Machine Vision Applications

MACHINE VISION APPLICATIONS - PHARMACEUTICAL INDUSTRY

Pharmaceutical industry is a quality critical industry because it has a close tie with peoples life and health. Vision inspecting system is often applied on the assembly line. The typical inspected objects usually include capsule, injection, bubble cap, label of the package etc. 
All Daheng Imaging cameras undergo thorough critical tests to ensure that they can meet the industrial and professional requirements under the tough conditions. Pharmaceutical production usually does not take place in a comfortable lab, but reliable inspection results in a tough environment are a guarantee for the drug quality. To get the reliable inspection results, Daheng Imaging cameras offer outstanding quality images with high-performance digital interfaces, as well as rapid trigger respond can ensure capture very precisely, furthermore, trigger signal filter function ensures that only the right pulses are inputted into the camera. No wrong image and no missing image are the most important keys for the vision system in pharmaceutical industry. Daheng Imaging cameras are just good at that.

Traffic & Transportation

 

 

The vehicle wheel set's fault and dimension dynamic detection system is a safety inspection system which is installed on the railway, it can be used to detect the wheel set’s geometric parameters that can check the tread wear and the flange wear. By computer analysis, the system can forecast the safety status of the vehicle wheel set, and make it convenient to deal with the failure of the vehicle in time. The system is a guarantee for the safety of a train, It can be used in online survey, locomotive warehousing survey, High-speed rail warehousing survey, subway warehousing survey and etc. 
All DAHENG IMAGING cameras undergo thorough critical tests to ensure that they can meet the industrial and professional requirements in the harsh conditions. The work environment of the vehicle wheel set usually is challenged, so the reliability and stableness of the camera is very important. In this application, some red spectrum lasers or some near-infrared lasers usually are used. The near-infrared lasers are more suitable in the outdoor environment  than the red spectrum lasers, because the visible spectrum laser is easy to be interfered by the sun light, some near-infrared cameras with some near-infrared lasers are required.

3D Application & Robot Vision


 

Un scanner 3D est un appareil qui analyse un objet ou un environnement réel pour collecter des données sur sa forme. Les données collectées sont utilisées pour construire des modèles numériques en trois dimensions. Les données 3D collectées sont utiles pour une grande variété d'applications, elles sont couramment utilisées pour la conception artistique, la conception industrielle, la rétro-ingénierie, l'inspection du contrôle qualité, les prothèses et la numérisation des artefacts culturels. Elles sont également utilisées pour les achats en ligne, la production de films et les jeux vidéo. 

De nombreuses technologies différentes peuvent être utilisées pour construire ces dispositifs de numérisation 3D, mais les méthodes les plus courantes sont la vision stéréo et la triangulation laser avec une feuille de lumière. Dans un système de vision stéréo, deux caméras ou plus avec une structure de lumière ou un réseau de codage sont utilisées, ce qui permet d'obtenir des informations en 3D sur la surface d'objets de forme arbitraire. 

L'idée de base de la technique de triangulation laser avec feuille de lumière est de projeter une fine ligne droite lumineuse générée par un projecteur de ligne laser sur la surface de l'objet à reconstruire. En dérivant les coordonnées de la ligne laser dans ces images, les coordonnées mondiales Y et Z peuvent être calculées par la relation d'étalonnage entre le plan de l'image et le plan du laser. En outre, si l'objet se déplace le long de l'axe de coordonnées X, la caméra peut capturer une série d'images de lignes projetées, ce qui permet d'obtenir les coordonnées X, Y et Z de l'objet. 

Les caméras d'imagerie Daheng sont bien adaptées aux scanners 3D, en raison de leurs caractéristiques : 
  • différentes résolutions et fréquences d'images  
  • Qualité d'image exceptionnelle 
  • légèreté et petite taille 
  • Haute précision de l'horodatage 
  • excellente compatibilité avec les exigences des scanners 3D portables ou de bureau.

Glass Bottle Production

 

We generally can see all kinds of glass bottles around our life such as beer bottle, drink bottle, perfume bottle, etc. These glass bottles usually belong to mould bottle which are produced by pouring liquid into a mould to create a given shape. And there is a glass tube of another kind to be used in medicine or pharmacy, they are usually produced without a mould and need more critical quality. 

In a glass bottle plants, vision systems are typically installed in the hot end or in the cool end of the process, the inspection machine employs high-speed cameras to acquire real-time images of a glass bottle, then gets detailed geometric parameters of the bottle and verify the detects. By comparing the measuring results with the pre-set dimensional parameters, the inspection machine can find out waste bottles and eject them from the production line, thereby providing a strong guarantee for the bottle quality and production efficiency. 

MER-131-210U3M, MER-132-43U3M, MER-503-36U3M and MER-131-75GM-P of MERCURY family have some special characters such as high frame rate, precise capture, plug and play, stable multi-camera running and so on. All these make them become engineer's favorite cameras in the inspection system of glass bottle . 

Daheng Imaging Cameras are well suited to the quality Inspection in the glass bottle industry , because of their features: 
-  High frame-rate 
-  Excellent image quality 
-  Ultra small, light and robust 
-  Capture the instant very precisely  
-  Work perfectly under the harsh conditions 
-  Stable mutil-camera running 
 

Logistics Industry

 

In the traditional logistics industry, the goods are usually sorted, read barcode and recorded by manual  operation, and then they are sent to the picking area. Because the types of goods, the shapes and materials are different, a large amount of manpower are required for the sorting. It not only takes a long time and have a high sorting error rate, but also has a high labor cost. It would greatly slow down the delivery speed . 

To find a solution for this situation, DAHENG IMAGING developed an vision sorting system that can rapidly classify the objects and get the position of the objects. This system is composed of DAHENG IMAGING’s compact digital camera, using USB3.0 interface to transfer data to a PC controller for analysis and processing. Finally, the Gigabit Ethernet interface is used to transfer the processed data to the robot for guiding the robot to perform the ‘pick up’ process. The sorting system can be used not only for automatic sorting in the logistics industry, but also for various industrial applications such as positioning, inspection, measurement, etc. as shown in the picture below.

This logistics vision sorting system is built by DAHENG IMAGING MERCURY cameras and a delta robot. The whole system is mainly composed of 3D image acquisition module, 3D image processing module, image coordinate transform to robot coordinate module, hand-eye calibration module, and robot control module.

First, "3D image acquisition module" captures the high-speed moving baskets on the conveyor line, and obtains three-dimensional information of the goods in the baskets. This image acquisition module is composed of two MERCURY cameras and laser light source. Both the FOV(field of vision) and the MR (measure range) cover the whole basket. Stereo vision method is used to reconstruct 3d geometry information of the object and get position of the object. 

After getting the 3D geometry information of the objects, "3D image processing module" divides the 3D features of the object into several separated pieces, and analyzes the most suitable grasping position of the goods, and then passes the position data to the "Image coordinate to robot coordinate" module. 

By using the result of hand-eye calibration, the "Image coordinate to robot coordinate" module transforms the most suitable grasping position of the goods which get previously to the robot coordinate. Through the communication protocol, the robot coordinate data will be transmitted to the robot and performed by the robot control module. According to the grasping robot coordinate, the robot will grasp the suitable goods precisely. 

Compared to the traditional robot grasping system, this 3D vision sorting system has several breakthroughs: 
a) Higher sorting speed  
b) Achieve from 2D plane grasping to 3D grasping . 
c)Succeed in reaching a new hand-eye calibration method even though the cameras and the robot are separated in the different field. 

MER-132-43U3M had been used in this 3D system. Thanks to compact size, light weight and high performance, the camera can be easily deployed under various challenging conditions and integrated into all kinds of automatic devices to accomplish machine vision tasks. 

DAHENG IMAGING Cameras are well suited to the transportation because of their features: 
-Ultra small, light and robust 
-Extremely low noise and compact design 
-A wide range of models available, support various CCD and CMOS sensors 
-Outstanding image quality 
-Reliable work in harsh environments 
 

Embedded Vision

 

Embedded vision has become very popular in recent years, and it is well suited for some applications where the primary emphasis is on low cost, power consumption, size and weight, such as pilotless automobile, unmanned aerial vehicle, robot and medical device etc. 

Over the past decade, personal computing platforms based on Intel architectures have maintained a substantial lead in processing power, ensuring their continued dominance of most industrial computing applications. But over the last few years, the architectures of ARM processors have been substantially upgraded by adding cores, instructions and faster pipelines to increase their performance, they have begun to compete head-to-head with Intel and AMD PC processors in industrial application. Embedded system continues to stand for low cost and low power consumption but it does not mean low processing power anymore. 

Today thanks for the tremendous progress of computational capacity, data accumulation, mathematical tools and so on, we can see the rapid growth of artificial intelligence (AI). Convolutional Neural Network (CNN) is a mathematical method as one part of AI field, and it is broken down into two parts: training and inference.   

A typical application of AI embedded system is for the pilotless automobile. In this application, AI technologies are used for the detection of obstacles, the recognition of signs, traffic lights, cars, and pedestrians etc. A bank of cameras are arranged on and around the automobile and responsible for offering the real-time images. The data training commonly has been performed in the data center before the automobile run on the road. And the inference algorithm that makes the detections to achieve is embedded on ARM platform. As one popular ARM platform, NVIDIA Jetson TX1 or TX2 platform is especially popular in this application due to its ARM+GPU processor, as well as GPUs are very good at manipulating computer graphics and image processing, and GPUs' highly parallel structure make them more efficient than general-purpose CPUs for algorithms where the processing of large blocks of data is done in parallel. 

In a successful story, DAHENG IMAGING MER-231-41U3C is used on NVIDIA Jetson TX2 for the real-time driving detection. Auto gain and auto exposure time of USB3.0 camera's features will make it well suit for all kinds of weathers and outdoor environments. The ARM Linux SDK of USB3.0 camera is based on 'libusb', which provides a generic access to USB device, so the data of USB3.0 cameras can freely be transferred to any ARMV7 or AMRV8 platform. 

The following arm platforms were extensively tested by DAHENG IMAGING: 
●　NVIDIA Jetson TX1/ TX2 
●　NVIDIA Tegra TK1 
●　Toradex  Apalis TK1 on Ixora Carrier Board 
●　Raspberry Pi 3B, incl. support of the camera module 

DAHENG IMAGING USB3.0 Cameras are well suited to the pilotless automobile, because of their characters: 
●　Auto gain and auto exposure time 
●　Excellent image quality               
●　Ultra small, light and robust 
●　Work perfectly in outdoor environment 
●　ARM Linux SDK for ARM Platform based on ARMV7/8 architecture

In the beginning I was sceptic because of the low prices, but support by email was great. They advise a lens and provided additional technical information. Unfortunately they don't offer a loan service, but I decided to try it. I had the cameras in house within 2 weeks and connection was easy. The SDK looks like the SDK from Basler so I felt directly comfortable with it. The camera and lens was a perfect match and now I'm able to read small DMC codes on large products with just a single camera.
