Panoramic image splicing device and method suitable for trailer

Abstract

The invention relates to the technical field of panoramic image generation, and in particular relates to a panoramic image splicing device and method suitable for a trailer. The device comprises a direction measuring unit and an image acquisition module; the direction measuring unit comprises a main vehicle connecting mechanism and a hanging rod main shaft; one end of the main vehicle connecting mechanism is mounted on the main vehicle, and the other end is provided with a main shaft mounting seat and a direction measuring ring; the direction measuring ring is positioned right above the main shaft mounting seat; a plurality of groups of far infrared receivers are distributed at the edge of the top of the direction measuring ring in an annular array; one end of the hanging rod main shaft is rotationally connected to the main shaft mounting seat, and the other end of the hanging rod main shaft is provided with a far infrared emitter; and the far infrared transmitter can be in signal connection with any group of far infrared receivers. According to the invention, the operation steps are reduced through the physical movement mode of the direction measuring unit, the occurrence of the blockage of the panoramic image due to the azimuth change is avoided, and the work smoothness is improved.

Description

technical field [0001] The invention belongs to the technical field of panoramic image generation, and in particular relates to a panoramic image splicing device and splicing method suitable for trailers. Background technique [0002] In the prior art, the overall vehicle only needs to display the panoramic image on the screen based on a table. For the trailer, when the trailer is turning, it is necessary to obtain the turning angle in real time and generate a corresponding table in real time according to the turning angle, and then based on The table generated in real time displays on the screen a panoramic image of the trailer as it turns. [0003] Chinese patent CN112308782A proposes an image mosaic method, including: including: using the FAST algorithm to perform feature extraction in the reference image to obtain candidate feature points; to filter the candidate feature points to obtain target feature points, so that all The feature frames created with the above target...

Problems solved by technology

[0004] In the above-mentioned invention, only the problem of overlapping images during splicing is solved, but the problem of needing to generate the corresponding table in real time according to the turning angle cannot be solved, which leads to a slow update speed of the panoramic image displayed on the screen, and also causes screen problems. The displayed panorama image update is stuck
