【概要描述】The concept of machine vision systems has been around for a long time, but in recent years it has really gained popular acceptance. With the development of the Internet, machine vision inspection is a sunrise industry, through the combination of automation equipment, can create value for enterprises. Next, give you a detailed introduction to the working process of machine vision testing equipment: 1. First, the workpiece detector is used to detect whether the object is near or moving to the center of the camera's field of view. Image acquisition card sends trigger pulse signal. 2. The image acquisition card sends the start pulse to the camera or lighting device according to the program and delay preset by the designer, but some cameras and lighting devices start when the system is initialized. 3. The camera stops the current scan and starts a new frame scan; Sometimes the camera needs to be in a waiting state until the initial pulse arrives, and the frame scan begins after the initial pulse arrives. 4. If the exposure strategy is used, the exposure structure should be opened before the camera starts a new frame scan. The exposure time is determined by the program or hardware according to your actual Settings. 5. If using an exposure strategy, use another start pulse to turn on the lighting, especially to match the start time to the camera exposure time. 6. After the camera is exposed, scan and output a frame of image. 7, if the camera output is analog signal, image acquisition card will be the camera received signal A/D conversion, the digital, if the output is digital signal, so it saves the image acquisition card thing. 8, the image acquisition card will send the image signal to the buffer, processor or computer memory for image processing and display. 9, processor or computer image processing, analysis, identification, measurement results or logical control variables, and then according to these results for processing, control other equipment (such as mechanical equipment) to complete the relevant actions, positioning. Correcting motion errors, etc., for example, correcting the position of a mechanical arm.
