Embodiment Construction

[0009] Attached below figure 1 Through the description of the embodiments, the specific implementation of the present invention will be further described in detail.

[0010] A calibration scene of an automobile surround view system, comprising first and second calibration blocks 10 and 20. The first calibration block 10 is symmetrically arranged on the central axis of the vehicle A to be calibrated in the length and width directions, and two adjacent first calibration blocks A second calibration block 20 is provided between the blocks 10, the center point of the second calibration block 20 and the center points of the two adjacent first calibration blocks 10 are connected to form a right triangle, and the center point of the second calibration block 20 It is a right angle vertex. Specific as figure 1 As shown, four first calibration blocks 10 and four second calibration blocks 20 are arranged symmetrically on the periphery of the parking place of car A. The first calibration bl...

Abstract

Provided is a vehicle round-looking system calibration scene. The vehicle round-looking system calibration scene comprises first calibration blocks and second calibration blocks, wherein the first calibration blocks are symmetrically distributed on central axes of the vehicle length direction and vehicle width direction of a to-be-calibrated vehicle, a second calibration block is arranged betweeneach pair of adjacent first calibration blocks, a center point of each second calibration block and center points of two first calibration blocks arranged adjacently form a right triangle, and the center point of each second calibration block is a right angle vertex. The vehicle round-looking system calibration scene has the advantages that the construction of the scene can be completed by arranging the calibration blocks in parallel around the vehicle body, the scene is simple, and the construction is convenient; the calibration blocks are divided into two groups according to the content of picture blocks and separately arranged in a visual overlapping area and a non-overlapping area, so that a computer can analyze and judge the orientation according to a real-scene picture taken by the calibration scene, an image can be automatically spliced and verified after feature points are extracted, and the calibration operation is fast and convenient.

Description

Technical field [0001] The invention belongs to the technical field of automobile image acquisition, and particularly relates to a calibration scene of a vehicle surround view system. Background technique [0002] As people pay more attention to traffic safety, more and more advanced technologies are applied to cars. Among them, the car surround view system can intuitively show the driver the surrounding conditions of the vehicle, which brings great benefits to driving safety. convenient. In the debugging process of the car surround view system, multiple cameras need to be calibrated, and then the images of each camera are stitched according to the calibration parameters to form a complete top view of the car body. The existing calibration scenes are complex to build and have poor anti-environmental interference capabilities. They need to manually specify target feature points, which makes calibration difficult and has a low success rate. Summary of the invention [0003] The pu...
