Motion sensing method and motion sensing device

A motion sensing device comprising:

• at least one infrared sensor configured to rotate relative to the motion sensing device and detect a human body in proximity to the motion sensing device;
• a camera configured to acquire a human body temperature distribution image;
• at least one processor coupled to the at least one infrared sensor and the camera;
• a non-transitory storage medium coupled to the at least one processor and configured to store a plurality of instructions, which cause the motion sensing device to:
• detect the human body and adjust rotation angle of the at least one infrared sensor to track the human body;
• acquire a human body temperature distribution image of the human body from the camera, and analyze a human body contour image based on the acquired human body temperature distribution image;
• acquire distance measurement between a moving part of the human body and the motion sensing device;
• compare the acquired human body contour image with stored human body contour images, and determine a target human body contour image matching with the acquired human body contour image from the stored human body contour images, and determine a two-dimensional motion corresponding to the target human body contour image;
• determine a corresponding operation according to the determined two-dimensional motion and the acquired distance measurement between the moving part of human body and the motion sensing device;
• determine a target control signal according to the determined operation and a relationship table defining a relationship between the number of operations and the number of control signals;
• and
• control the motion sensing device according to the determined target control signal.
