Vehicle-mounted around view display method and system

Abstract

The invention relates to a vehicle-mounted around view display method and system. The left side and the right side of each compartment of a vehicle are respectively provided with at least one camera, the front and the rear of the vehicle are respectively provided with at least one camera, each compartment is provided with at least one angle sensor, and a lookup table for recording the mapping relation of original image pixels and firstly spliced panoramic image pixels and recording compartment belonging information of pixels in a firstly spliced panoramic image is prebuilt; rotating angles of the corresponding compartments are detected through the angle sensors, and original images are collected respectively through the cameras; the mapping relation of panoramic display image pixels and the pixels of the firstly spliced panoramic image is calculated according to the rotating angles of the compartments, a panoramic display image is spliced and output in real time. The method and system are especially suitable for the vehicle with the multiple compartments, images of the surrounding conditions of the vehicle are provided for a driver when the driver parks the vehicle or turns the vehicle around, safety is improved when the driver parks the vehicle or turns the vehicle around, and accidents caused when the driver parks the vehicle or turns the vehicle around are effectively avoided.

Description

technical field [0001] The invention relates to the technical field of vehicle-mounted surround view, in particular to a vehicle-mounted surround-view display method and system, especially suitable for vehicles with multiple compartments. Background technique [0002] With the improvement of people's living standards, the transportation industry has become more and more developed, and automobiles have become an indispensable means of transportation for people to travel and a means of transportation for transporting goods. However, along with the increasing tension and scarcity of land, the parking spaces in places such as highways, streets, and parking lots are limited in size, which requires very high parking skills for drivers. It is difficult for drivers with limited parking skills to park accurately, and accidents that collide with surrounding vehicles or objects often occur during parking. [0003] Aiming at the safety hazards of the above-mentioned parking, a panorami...

For example, the application date is 2010-12-15, and the application number is 201010590428.8. The Chinese invention patent "A Vehicle Surround View Display System" provides a more intuitive way for the driver to present the situation around the car to improve the process of parking the vehicle. The safety and stability of the vehicle-mounted surround-view display system, but the vehicle-mounted surround-view display system is only suitable for cars with a single compartment, such as private cars, etc. For vehicles with multiple compartments, such as trailers, the vehicle-mounted surround-view display effect is poor

Since the vehicle is connected to more than one compartment, when the vehicle is reversing or turning, the front of the vehicle and each compartment are not at the same angle. If the parking method of a car is used, the surrounding conditions of the vehicle cannot be accurately displayed by directly cutting and splicing pictures to assist vehicle safety. The effect of parking or turning safely is poor, and accidents caused by parking or turning cannot be effectively avoided
