Gesture signal processing device and method based on diaphragm and pinhole near-field imaging

The invention discloses a gesture signal processing device and method based on diaphragm and pinhole near-field imaging. The gesture signal processing device is provided with a pinhole structure and a diaphragm hole; the small hole structure is arranged on the small hole shading plate; the small hole structure is located in the center of the gesture signal processing device in the horizontal direction. The diaphragm holes are formed in the diaphragm hole seat and distributed on the two sides of the gesture signal processing device in the horizontal direction; the LED array faces a detected object; the photoelectric sensor obtains light emitted by the LED array reflected by the detected object through the small hole structure and the diaphragm hole. By adopting the technical scheme, the accuracy of gesture recognition can be improved; the function of measuring physiological parameters of a human body is achieved; the functions of motion error compensation and physiological parameter measurement are achieved; a
