Automatic control method of mechanical arm and automatic control system

An automatic control system of a mechanical arm, comprising:

• a depth camera, configured to obtain a color image and depth information corresponding to the color image;
• and
• a processor, coupled to the mechanical arm and the depth camera, configured to perform image space cutting processing and image rotation processing according to the color image and the depth information to generate a plurality of depth images,
• wherein the processor inputs the depth images into a neural network operation model of the processor for outputting a displacement coordinate parameter, wherein the processor performs eigenvalue analysis on each of the depth images to generate spatial weight matrix data corresponding to the depth images, the processor determines a minimum weight value of the spatial weight matrix data as a position of the mechanical arm in a next frame, and the processor treats the one corresponding depth image as an effective safe space image;
• and the processor outputs the displacement coordinate parameter such that the processor controls the mechanical arm to move toward the position with the minimum weight value according to the displacement coordinate parameter.
