Description

(1) Technical field: [0001] The invention is a distributed electromagnetic human body motion detection device, which belongs to the field of electronic technology. (two) background technology: [0002] With the development of engineering bionics, sports medicine, robot control and large-scale network virtual reality technology, there is an urgent need for miniaturization, passivity and precision of human motion detection devices. Existing human body motion detection devices have the following several types: one is the multi-view synthesis device in the fixed field of view, which generally captures live motion images from different angles through the CCD lens distributed in a specific space, and then according to a certain spatial relationship Restructure the movement process. The second is to use the three-point positioning method of ultrasonic waves, infrared light waves and wireless electromagnetic waves at a fixed emission position to determine the absolute coordinates o...
