Industry Challenges and Needs
The varied appearance and complex structure of sand cores make traditional manual inspection difficult to ensure accuracy and timeliness. 2D inspection fails to capture the height information of the object, whereas 3D laser scanning technology enables non-contact, online, high-precision inspection, offering significant comparative advantages.
Solution
Based on the principle of laser triangulation, the use of a 3D high-speed camera combined with an ultra-high precision blue laser enables precise scanning of the sand core's external contours. This method can detect standard geometric dimensions of the sand core, including length, width, and depth (the height difference between the inspection surface and the reference surface).
