Problems solved by technology

The recently developed panoramic parking system installs four wide-angle cameras on the front, rear, left, and right sides of the car, and then uses image processing technology to synthesize them into a complete bird's-eye view and display them on the LCD screen. The car owner can see the road conditions in all directions of the car. It has been greatly improved in comparison, but several pictures are synthesized on one screen, and the visibility is relatively poor, especially for car owners with low driving skills, they need to pay attention to watching the pictures on the screen of the car host during serious driving. Synthetic graphics, not conducive to efficient parking

Embodiment approach

[0054] There are many control methods for automatically selecting and outputting the image of the surrounding environment of the car and the distance between the car and the obstacle according to the detected vehicle driving state and the angle between the driver's line of sight and the driving direction of the car. The present invention defines a more reasonable implementation mode , specifically as follows: the vehicle status acquisition module acquires the driving status of the vehicle through the CAN bus, and the angle detection module detects two heading angles. heading angle β 2 Relative to the vehicle heading angle β detected by the three-dimensional electronic compass 1 installed on the vehicle host 1 , the angle deviates from | beta 2 —β 1 | When it is less than the set value, if the car is driving forward, the logic analysis and control module controls and switches the image and distance in front of the car and transmits information such as the image and distance...

Abstract

The invention discloses a driving assistance system and method based on head-mounted display and used for automatic scene selection for display. Four wide-angle cameras and six groups of radar transmitting and receiving devices are mounted all around a car body so as to collect images around the car and detect distances between the car and surrounding obstacles in real time, a relative direction (angle) between a diver head (sight) and an automobile is calculated through relative angles collected by a three-dimensional electronic compass on a driver helmet and a three-dimensional electronic compass mounted on the car body, then a logical analysis and process function module performs operation processing, and finally, real-time synchronous display is performed on the head-mounted display (goggles). Therefore, through a panoramic parking helmet, the driver can see the position of the car and the obstacles around the car conveniently and intuitively when sitting in the car.

Description

technical field [0001] The invention relates to the field of automotive electronics, in particular to a driving assistance system and method for automatic scene selection and display based on a helmet-mounted display. Background technique [0002] In recent years, due to the continuous increase of urban vehicles, the requirements for parking / reversing have been continuously improved. According to market demand, various driving assistance systems have gradually developed. [0003] At present, there are mainly reversing radar systems with ultrasonic ranging, track reversing and panoramic parking systems on the market. The reversing radar system is susceptible to interference and has no disadvantages such as the image is not intuitive enough. There is only one rear mirror in track reversing, and you can't see the road conditions in front, left and right. The recently developed panoramic parking system installs four wide-angle cameras on the front, rear, left, and right sides ...
