Problems solved by technology

[0005] The object of the present invention is to provide a vehicle panoramic monitoring method and system for a vehicle, aiming to solve the following problems in the prior art panoramic video system for motor vehicles: No dead angle monitoring; 2. The dynamic connection car cannot be completely stitched together and there is a problem of dead angle in the stitched view; 3. Due to the long body and the change in the angle of the connected car body, the panoramic view of the traditional bird's-eye view and the view of a single camera Unable to meet the driver's observation habits, affecting the driver's effective observation of the car body and surrounding areas; 4. The problem of not being able to accurately calculate and draw the dynamic trajectory of the trailer part for the dynamically connected car

Abstract

The present invention is applicable to the field of automotive electronics, and provides a panoramic video monitoring method and system for motor vehicles, which can obtain the angle between the central axis of the main vehicle of the motor vehicle and the central axis of the trailer of the motor vehicle; and confirm the monitoring according to the obtained angle The monitoring area includes multiple sub-areas, and the multiple sub-areas constitute the panoramic area of ​​the motor vehicle; the mapping from the coordinates of each sub-area in the monitoring area to the coordinates of the display screen is established; a panoramic image is generated and displayed on the display screen according to the mapping establishment result. Therefore, the monitored sub-area can be confirmed according to the angle between the main vehicle and the trailer of the motor vehicle, and the monitoring area changes dynamically with the state of the motor vehicle. The driving track line realizes the complete panorama stitching of the dynamically connected vehicles, monitors multiple or more than two dynamically connected vehicles without blind spots, and improves the accuracy of the panoramic monitoring of motor vehicles.

Description

technical field [0001] The invention belongs to the technical field of automotive electronics, and in particular relates to a panoramic video monitoring method and system for motor vehicles. Background technique [0002] The use of driving assistance systems in motor vehicles can effectively observe the blind spots of driving, and the panoramic video recording system usually installs more than one camera around the vehicle body, so that the viewing angle covers all or most of the area around the vehicle body. And by directly displaying the camera video in different areas on the screen; or by the method of image video splicing, transform and splicing several camera videos to form: 1. A panoramic image with a bird's-eye view, intuitively showing the positional relationship between the vehicle body and the surrounding environment; 2. Display single-channel or multi-channel camera video from a special perspective, for example, from the driver's perspective from the left and righ...
