Automobile gesture control device based on single-chip microcomputer and control method thereof

Abstract

The invention provides an automobile gesture control device based on a single-chip microcomputer and a control method thereof. The single-chip microcomputer serves as a main control unit, an infraredlight supplementing lamp is used for projecting infrared light, and a monocular camera with an infrared filtering piece is used for capturing user gesture images which are transmitted to the single-chip microcomputer module. The single-chip microcomputer module is used for analyzing and processing the user gesture images, and controls a device control module to operate an automobile device, so that the gesture control of the automobile device is realized. The invention is advantageous in that the single-chip microcomputer module has excellent expansibility and can be connected with different device driving modules according to actual demands, different automobile devices can be driven, and the purpose of controlling multiple in-vehicle devices by using gestures can be achieved; meanwhile,the infrared light supplementing device is adopted to be matched with the monocular camera, so that the infrared light supplementing device can be used under the condition of low illumination; the automobile gesture control device is more suitable for being applied to a vehicle, and can still be normally used when no sunlight is used for night driving.

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
