3D camera, also known as depth camera, is different from 2D camera, 3D camera can obtain the depth of field distance of the shooting space. Through the data obtained by the 3D camera, we can accurately know the distance of each point in the image from the camera, plus the (x, y) coordinates of the point in the 2D image, we can obtain the three-dimensional space coordinates of each point in the image , restore the real scene through three-dimensional coordinates, and realize the application of scene modeling, product volume detection, defect detection, railway detection and so on.

The solution of the industrial 3D camera mounted on the robotic arm of the welding robot can be flexibly applied to various scenarios. Such as initial welding position guidance, welding seam tracking, relative deformation detection, etc. However, in the process of actual project landing, the solution of the industrial 3D camera mounted on the robotic arm of the welding robot often encounters some special pain points:
1. The load of the robotic arm of the welding robot is small, and it is difficult to bear the large volume and weight of the high-precision camera;
2. The small-volume camera is lacking in accuracy and cannot meet the imaging requirements of welding operations;
3. High-precision 3D cameras are often expensive;
At present, most welding robots on the market use the line laser method, which has high precision but slightly lower efficiency.
