A 3D vision detection system obtains the 3D contour data of the target through 3D contour sensors, and analyzes and processes the data with the vision software to achieve the purposes of size measurement, defect detection, target recognition, etc. The 3D vision measurement system can obtain the width, height and other information of the target more comprehensively, and has the advantages of strong anti-interference ability and high detection accuracy. It can be widely used in 3D dimension measurement of parts, accurate workpiece assembly measurement, defect detection, and other project requirements.
Principles of vision:
Cut the area where the character is located on the height grayscale map, calculate the difference between the average grayscale values inside and outside the area, and then convert the result to obtain the depth value. Compare the character area identified with the template to find the difference for defect detection.
The general software of 3D character vision detection is compatible with:
Disc engraving process, diamond engraving process and laser engraving process;
RAIVAS 3D profiler (OEM), Keyence 3D profiler, Cognex 3D profiler, LMI 3D profiler, and 3D profiler of other brands.
Three technical advantages:
3D point cloud imaging for overall high-precision identification of characters.
AI recognition compatible with the font recognition of different automobile enterprises.
Open Platform Communications (OPC) for data comparison with the production instructions of the customer's MES system.
