Steps Depth Chart

The Steps Depth Chart is designed to verify the depth information output by Depth cameras whichever technology they use. It is composed of 12 different depth gray scales of 18% reflectance, each with a depth difference of 2mm. Starting from the zero-reference plane of the substrate, the lowest block increases step by step from 8mm to 30mm, and the background plane above it is 19mm away from the base plate.
