What is a 3D depth camera?

3D depth camera DMOM2808D

With the gradual development of technologies such as machine vision and autonomous driving, there are more and more applications related to the use of 3D cameras for object recognition, motion recognition, and scene modeling. It can be said that 3D cameras are the eyes of terminals and robots. The purpose of DOMI 3D depth cameras is Let every terminal understand the world. So what is a 3d depth camera, and what is the difference compared with the previous ordinary camera (2D)?

A 3D camera is also called a depth camera. As the name implies, the camera can detect the depth of field distance of the shooting space. This is also the biggest difference from an ordinary camera. The pictures taken by ordinary color cameras can see all the objects in the camera’s angle of view and record them, but the recorded data does not include the distance of these objects from the camera. We can only judge which objects are far away from us and which are closer through the semantic analysis of the image, but there is no exact data. The 3D camera just solves this problem. With the data obtained by the 3D camera, we can accurately know the distance of each point in the image from the camera, so that by adding the (x,y) coordinates of the point in the 2d image, we can Get the three-dimensional space coordinates of each point in the image. The real scene can be restored through three-dimensional coordinates, and applications such as scene modeling can be realized.
