  Machine vision inspection is widely used. Machine vision inspection can not only control the quality of enterprise products, but also machine inspection can greatly improve the detection accuracy compared with manual inspection. However, in actual testing, there are certain problems in machine vision inspection. Let's take a look at TEO Xiaobian.

  What problems should be paid attention to when the machine vision inspection equipment is running?

  In the application of machine vision inspection equipment, it mainly includes four aspects: measurement, detection, identification and positioning. The measurement is most likely to be affected by illumination. Only the illumination changes by 10%-20%, and the measurement result can have a large error. It is around 1 to 2 pixels. These problems are not software problems, but the lighting causes the edges of the image to change. Therefore, when providing customers with machine vision system solutions, it is necessary to minimize the interference of the light source lighting problem and ensure the stability of the machine vision system light source.

  In the design of the machine vision system, it is necessary to consider the problem that the detected position of the detected object changes in the field of view of the customer. Under the high quality requirements, the position correction or other forms only by the fixture can not completely ensure that the target to be tested is in the same position, and there will be a large error in the detection. Therefore, when detecting, it is necessary to cooperate with the positioning function to ensure that the measurement result deviation is small enough.

  The above is the relevant introduction of TEO on the problems that machine vision inspection equipment needs to pay attention to during operation. TEO brings together senior audio and video technology experts and professionals who have been engaged in the sales and management of the machine vision market for many years. It has the IEC International Electrotechnical Commission TC79 Safety and Protection Technology Branch Chinese experts, SAC/TC100 National Security and Alarm System Standardization Technical Committee, International Standardization Technical Experts. It is the first, second and third directors of the China Security Industry Association, the executive director unit of the Shenzhen Security Industry Association, and the Shenzhen Robot Industry Alliance. Over the years, he has paid great attention to academic exchanges and actively participated in the drafting, demonstration or validation of technical standards such as ISO International Standardization Organization, SAC National Standardization Management Committee, local government, and industry alliances.
