Automobile seat posture intelligent control method based on binocular vision

Abstract

The invention relates to an automobile seat posture intelligent control method based on binocular vision. The method comprises the following steps: S1 installing an automobile binocular camera at a proper position of an automobile roof along the side direction of an automobile, carrying out the parameter calibration of the binocular camera, obtaining the baseline distance B of the binocular camera, and measuring the vertical height Hc from the optical center of the binocular camera to the ground; S2 after a person enters a proper distance range, collecting a video signal that the person moves towards the automobile through the binocular camera; S3 calculating the height Hhuman of the human body through a binocular vision imaging principle; S4 estimating main static human body size parameters of other parts of the human body through the height; S5 determining an optimal seat comfort position corresponding to the human body size data according to an ergonomics principle, and obtaining the horizontal position, height and backrest inclination angle information of the seat; and S6 inputting the seat parameters into an automatic regulation and control system, enabling a motor device to drive the seat to adjust the position, and achieving automatic adjustment of the horizontal position, the height and the backrest inclination angle of the seat.

Description

technical field [0001] The invention belongs to the field of intelligent control, in particular to a binocular vision-based intelligent control method for seat attitude. Background technique [0002] With the rapid development of my country's smart car field, the smart cockpit has become an important part of smart driving. Seat is an important part of the cockpit, and the automation and intelligence of seat adjustment has become the focus of current research. [0003] The demand for automatic adjustment seats can be understood from the following three levels. From the perspective of the development of automobile technology, the automatic adjustment of car seat position is an important part of the development of automobile intelligence. It realizes a higher level of human-computer interaction between cars and people, and will become the main field of future smart car development. One; from the perspective of car manufacturers, the automatic seat adjustment mechanism is a ma...

Problems solved by technology

[0004] For now, the height, front-to-back distance, and backrest inclination of traditional seats are mostly adjusted by passengers themselves after getting on the bus. Situations where the previously adjusted seat position of the passenger cannot meet the long-term ride comfort requirements

[0005] In addition, for now, computer vision has made great progress. In this field, the use of binocular vision to measure the depth information and size information of objects has also been tried and researched. However, using binocular vision to estimate human body information parameters and using the acquired Combined with ergonomics to guide the intelligent adjustment of the seat position and realize the intelligent and automatic seat adjustment, the research in this area is still relatively weak
