Sun shield three-dimensional control method considering seat position and body type based on cameras

Abstract

The invention discloses a sun shield three-dimensional control method considering the seat position and the body type based on cameras. The sun shield three-dimensional control method considering theseat position and the body type based on the cameras comprises the specific steps that panoramic cameras are started, the sunlight irradiation intensity is judged by detecting the brightness of a picture, an intensity signal is sent to a control unit, and the control unit receives the signal and judges whether the sunlight irradiation intensity reaches the standard or not; and when the intensity reaches the standard, the control unit is connected with the panoramic cameras, and the direction of the sun irradiating the automobile at the moment is judged through the brightness and colors of pictures shot by the four panoramic cameras. Existing equipment of a vehicle are borrowed, hardware equipment is not additionally arranged, the light intensity, direction and angle of sun irradiation canbe accurately judged only through software, the body type of a driver, the position of a seat and the inclination angle of a backrest of the seat are considered, and the accuracy of obtained control information is high. In addition, the sun shield can rotate in a three-dimensional mode, and a good effect on lateral irradiation is achieved.

Description

technical field [0001] The invention relates to the technical field of automobile sun visor control, in particular to a three-dimensional control method for a sun visor based on a camera and considering seat positions and body shapes. Background technique [0002] With the advancement of science and technology and the development of society, the number of car ownership continues to increase, and cars have become a common means of transportation for people to travel. Now cars are becoming more and more intelligent and networked. [0003] At present, car sun visors are manually adjusted. Some manufacturers have introduced smart car sun visors, which collect information through light sensors and adjust the sun visors. The more expensive ones are to adjust the transmittance of the LCD screen. The price is high and there are few applications.

Problems solved by technology

[0003] At present, the car sunshade is adjusted manually. Some manufacturers have introduced smart sun visors for cars, which collect information through light sensors and adjust the sun visor. The more expensive ones are to adjust the transmittance of the LCD screen. The price is high and there are few applications.

There are some conceptual liquid crystal screen products in the prior art, which have not yet been put into use on a large scale. Other motor-controlled automatic sunshade products can only rotate up and down, and the effect on the side sun is poor; The side and front illumination and feedback control have low control accuracy for the sun visor; an additional light sensor is required, and the position of the light sensor is also easily affected. Using TBOX to communicate with the outside world to obtain the sun’s radiation angle requires an additional monthly traffic package fee. Huge increase in use cost, low maturity and high price
