小草社区免费视频大全The main functions of intelligent vision system can be simply summarized as: location, recognition, measurement, defect detection, etc. Compared with artificial or traditional mechanical methods, intelligent vision system has a series of advantages, such as high speed, high precision and high accuracy. With the development of industrial modernization, intelligent vision has been widely used in various fields. For enterprises and users to provide better product quality and perfect solutions. Line detection is the most application of intelligent vision. The basic requirement of pipeline detection is to find the area to be detected in time after taking photos. This technology is geometric matching. The following describes the application of geometric matching in intelligent vision system:

小草社区免费视频大全When the product needs high-precision positioning, the geometric matching function can be used. First, a mark point (mark point) can be made on the product in advance, then the position deviation of the mark point on the product relative to the position on the picture can be detected, and then the detected deviation can be converted into millimeter or the pulse drive motor can be adjusted back to the corresponding position through the camera calibration to achieve high-precision positioning.


Target recognition and classification

2. Inspection of product direction

When the product needs to detect the direction and presence, it can find a sign point on one side of the product or a corresponding contour right angle edge, hypotenuse, arc and other geometric figures as a template. When the software finds the corresponding template within a certain range, it thinks that the product has the right direction and that the direction is reverse. At this time, it can send a signal to the product Eliminate or control the corresponding motor to turn the product in the opposite direction.

When the product needs to measure the distance between two points and the distance measurement and caliper measurement can not meet the product measurement requirements, the product measurement can be achieved by matching the contour of two points at the same time, which is mainly used for products with poor polishing effect.

4. Correctness of product placement

When some small products or accessories need to be placed or assembled on the product, it is usually necessary to test the correctness. In this case, you can set the corresponding search range in the location of small products or accessories to learn the corresponding template to achieve the test purpose, that is, search a template in the range a, search B template in the range B, search C template in the range C. if all the searches are successful, then OK, if any If a range search is unsuccessful, then ng.

When the character (number or letter) of the product needs to be detected, the character extraction function of the machine vision image processing software can be used, but the geometric matching must be used as the auxiliary positioning. Because the position of the product under the camera usually changes, and the full image range search may increase some miscalculation, so we can set a very small search range And this range can change with the deviation of the matched mark point.

In the early days, high complexity product industries, such as semiconductor industry and electronic industry, have traditionally promoted the development of machine vision market due to their complexity and miniaturization. But now, all industries, including automation, pharmaceutical, papermaking and other fields, rely on machine vision system to detect products to improve product quality. It can be predicted that in the future, machine vision will become a universal technology across all industries and an indispensable solution for industry users.
