Problems solved by technology

[0006] The technical problem to be solved by the present invention is that the splicing quality of the plane splicing view of the existing automobile panoramic image monitoring system can be recognized subjectively, but it is not easy to be identified subjectively and the specific defect level cannot be judged subjectively. Subjective evaluation is not convenient for accurately describing the splicing quality. And currently there is no objective evaluation method in the industry

Embodiment Construction

[0057] In order to further understand the invention content, characteristics and effects of the present invention, the following examples are given, and detailed descriptions are as follows in conjunction with the accompanying drawings:

[0058] This embodiment discloses a method for evaluating the splicing quality of a plane splicing view in an automobile panoramic image monitoring system. The method is based on objective image testing and analysis, and is easy to implement on site. The splicing quality data is easy to handle and the calculation is simple and easy to automate.

[0059] In order to meet the driver's vision requirements in low-speed car movement and reversing events, the car panoramic image monitoring system stitches the images collected by multiple cameras according to the spatial distribution of the camera entities, and provides a flat spliced ​​view output on the display terminal of the car panoramic image monitoring system . And because this view is spliced...

Abstract

The invention provides a splicing quality evaluation method for a plane splicing view of an automobile panoramic image monitoring system. The method comprises the following steps: (1) uniformly distributed environment illumination covers the view field of the automobile panoramic image monitoring system; (2) covering the checkerboard graph card in the view field of the plane splicing view of the vehicle panoramic image monitoring system; (3) using an image acquisition device to shoot and acquire a plane splicing view image; (4) identifying a splicing gap; (5) identifying the spliced ghosting; (6) identifying splicing dislocation; and (7) identifying splicing loss. Based on objective image test and analysis, the method is easy to realize on site, splicing quality data is easy to process, calculation is simple, and automation is easy to realize, so that the splicing quality of the plane splicing view of the automobile panoramic image monitoring system can be rapidly, conveniently, effectively and consistently evaluated.

Description

technical field [0001] The invention belongs to the technical field of visual image performance evaluation, and relates to an automobile advanced driving assistance system-an automobile panoramic image monitoring system, and specifically relates to a technical method for evaluating the splicing quality of the plane spliced ​​views at the display end of the automobile panoramic image monitoring system. Background technique [0002] Automobile panoramic image monitoring system, that is, a system installed on a vehicle to display real-time images within a 360-degree range around the vehicle in the form of a visual video stream. Scene visual information in a large range is of great significance to improve driving safety. The market demand for such products is strong, and it is the prevailing configuration of M-type and N-type non-articulated vehicles. The car panoramic image monitoring system generally collects images through visible light cameras and provides the driver with re...
