Embodiment Construction

[0018] Attached below Figure 1-7 , through the description of the embodiments, the specific implementation of the present invention will be further described in detail.

[0019] A three-dimensional calibration scene of an automobile surround-view system, comprising a central area 10 for parking a vehicle X to be calibrated, the central area 10 is a rectangular area, and the outer sides of the four corners of the central area 10 are respectively symmetrically provided with calibration units 20, each The first calibration unit 20 is provided with a calibration surface 30, the calibration surface 30 is located in the plumb plane and arranged facing the vehicle X. Since the calibration surface 30 is arranged vertically, it can avoid light, sunlight and other light reflected on the ground to form a bright part that interferes with the calibration surface, thus greatly improving the success rate of calibration. At the same time, since the calibration surface 30 is arranged vertica...

Abstract

A three-dimensional calibration scene of an automobile panoramic system comprises a central area used for parking a to-be-calibrated vehicle, the central area is a rectangular area, and the outer sides of the four corner points of the central area are symmetrically provided with calibration units respectively; each calibration unit is provided with a calibration surface, and the calibration surfaces are located in a plumb bob surface and arranged facing the vehicle. The calibration surfaces are far away from the running path of the vehicle, so that the calibration scene is high in reliability.The calibration surfaces located in the plumb bob surface effectively avoid calibration failures caused when light is reflected on the ground and makes characteristic points disappear, and the calibration success rate is greatly increased. The calibration operation using the calibration scene is simple, the computer detection precision is high, the success rate is high, and calibration can be completed without manual operation.

Description

technical field [0001] The invention belongs to the technical field of automobile image acquisition, and in particular relates to a three-dimensional calibration scene of an automobile surround view system and a calibration method using the scene. Background technique [0002] As people pay more attention to traffic safety, more and more advanced technologies are applied to automobiles. Among them, the car surround view system can intuitively show the driver the surrounding conditions of the vehicle, which has brought 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 spliced ​​according to the calibration parameters to form a complete overlooking picture around the car body. In the prior art, the method for calibrating multiple cameras on the vehicle is complex, requiring manual designation of target feature points, cumbersome operation, compl...
