Automobile vision switch control system

Abstract

The invention discloses an automobile vision switch control system. The system comprises an automobile main engine, a camera, a vision processing unit, and a vision control switch. During running, thecamera carries out real-time monitoring to obtain binocular dynamic features of a driver, the features are output to the vision processing unit, the vision processing unit generates a human eye dynamic digital model, on the basis of the model, binocular focal point high-frequency calculation is carried out, a determined human eye focal point space position is compared with space position of the vision control switch built in the vision processing unit, whether an equipment operator watches a certain vision control switch or not is judged, a judging result is output to the automobile main engine, the automobile main engine issues a control instruction to equipment, and vision control over the automobile function can be achieved. The blinking frequency or fixation duration serves as an instruction signal to be subjected to function control, and vision control is achieved.

Description

technical field [0001] The invention belongs to the technical field of automobile visual interactive control, and relates to an automobile visual switch control system. Background technique [0002] With the rapid development of the automobile industry, automobiles are no longer just a simple means of travel. The content of interaction between people and automobiles is becoming more and more abundant, and the forms of interaction are becoming more diverse, from traditional switch control to touch screen control, to Today's voice control, gesture control, and car control are becoming more and more humanized, and drivers are becoming more and more worry-free. In particular, the development of automatic driving technology has directly changed the definition of driving, and drivers have gained more space in the car. The degree of freedom, the car has gradually changed from the initial travel tool to a private and comfortable space and a mobile office space. Automatic driving is...

AI Technical Summary

Problems solved by technology

[0005] 1. Traditional buttons, knobs, and levers need to be arranged in the interface that can be touched by human hands, which takes up more cabin space, limits the diversification of vehicle structures, and cannot achieve a simple and coherent interior design. At the same time, these components It produces cumbersome manipulation actions, and the formation of complex electrical circuits inside is also a potential safety hazard that cannot be ignored

[0006] 2. With the increase of additional vehicle functions, in the case of limited touch screen area, the icon is small and difficult to observe, and the icon is too large and the level is deep, requiring multiple page turning

Usually, completing an operation requires at least two or three touches, and as many as seven or eight touches, which is cumbersome and inefficient

In the future, when large-size screens are used to improve the visual experience in unmanned driving scenarios, touch-screen operations also have the problems of large single-operation distance and high operation frequency

[0007] 3. In a multilingual background, the recognition accuracy of speech semantics is low, the impact of space environment factors on speech recognition (such as noisy environment, someone talking next to you) is relatively large, the distance of speech recognition and the sound scene are limited

[0008] 4. Gesture operation, according to the survey, the car gesture control should be within 14, too many gestures will take up a lot of learning costs and energy for the driver

Gesture commands must be operated in a specific area. At the same time, all gestures must also meet the system's standard requirements for actions, otherwise it is prone to misoperation, which cannot meet the requirements in complex driving situations.
