Embodiment

[0058] Taking a vehicle with N carriages as an example, the number of carriages is based on the carriage at the rear of the vehicle, and is added sequentially toward the front, that is, the rear carriage is the first carriage, and the front carriage is the Nth carriage. like figure 1 As shown, a vehicle-mounted surround view display method, a camera is respectively installed on the left and right sides of each compartment of the vehicle, a camera is respectively installed at the front and rear of the vehicle, and an angle sensor is respectively installed in each compartment, such as figure 2 As shown, the parking assistance method pre-establishes the look-up table and the steps of real-time splicing and outputting images during use, and the specific process is as follows:

[0059] S1 establishes in advance a lookup table that records the mapping relationship between the pixels of the original image and the pixels of the first-time stitched panoramic image and the belonging in...

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...
