A single-chip microcomputer-based automobile gesture control device and its control method

Abstract

The present invention proposes a single-chip microcomputer-based automobile gesture control device and its control method. The present invention uses a single-chip microcomputer as the main control unit, uses an infrared supplementary light to project infrared light, and uses a monocular camera with an infrared filter to capture user gestures. The image is sent to the single-chip microcomputer module. The single-chip microcomputer module analyzes, processes and recognizes the user gesture image, and controls the equipment control module to operate the vehicle equipment, thereby realizing the gesture control of the vehicle equipment. The single-chip microcomputer module of the present invention has excellent expansibility, and can be connected with different device drive modules according to actual needs to drive different automobile devices, so as to achieve the purpose of using gestures to control various in-vehicle devices. At the same time, the present invention uses an infrared supplementary light device with a monocular camera, which can be used under low-illumination conditions, and is more suitable for use in cars, especially when driving at night without daylight illumination, it can still be used normally.

Description

technical field [0001] The invention belongs to the technical field of gesture recognition, in particular to a single-chip microcomputer-based automobile gesture control device and a control method thereof. Background technique [0002] The most common control methods for automotive accessories are physical push buttons or rotary buttons. Push-type buttons, when not subjected to external force, the button contacts are in a separated state, and the button is electrically closed after pressing, so as to judge that the button is pressed, and then control the auxiliary equipment in the car, such as: adjust the angle of the car rearview mirror, switch Door locks etc. Knob-type buttons usually have a "common end". When the knob is rotated to a fixed position, the contacts currently connected to the "common end" are disconnected, and the contacts of this gear are connected to the "common end" Through communication, to distinguish different gears, thereby controlling the auxiliary...

Problems solved by technology

[0007] The traditional push-button and knob-type button solutions require human hands to touch the designated buttons and apply a certain amount of force. The operation method is old and cumbersome and laborious. The gesture control solution is more novel than the traditional physical button control method, and the operation is convenient and saves space. , there is no longer any need for physical buttons, and no need for human hands to touch the control device; but the current electromagnetic induction scheme has a very short operating distance and can only recognize simple gestures. It is difficult to recognize complex gestures and has low sensitivity; while binocular vision and 3D The image processing scheme has a large amount of calculation, high requirements on the platform, high cost, and is not easy to integrate and maintain
