Abstract

The present application provides a system and method for determining external parameters of a photographing device, which belong to the technical field of photographing devices. The method includes: during the moving process of the integrated board, acquiring the target image of the corresponding calibration board sent by each of the photographing devices, wherein at least two photographing devices are arranged on the integrated board, and each of the photographing devices corresponds to A calibration board; according to the target image, determine the target posture of the shooting device relative to the calibration board; according to a plurality of the target postures, determine the external parameters between the shooting devices. In this application, the external parameters between the shooting devices can be known only through the attitude of each shooting device relative to the calibration plate, and there is no need for the shooting devices to have a common visual range, which expands the scope of application.

Description

technical field [0001] The present application relates to the technical field of photographing devices, and in particular to a system and method for determining external parameters of a photographing device. Background technique [0002] Multi-camera calibration technology refers to the use of at least two cameras to shoot at the same time, and then convert the positioning results of different cameras into a unified coordinate system through the relative position relationship (external parameters) of the multi-cameras, and realize the mapping from 2D to 3D coordinates. Build a 3D image. Multi-camera calibration technology should be widely used in many fields, such as realizing spatial positioning and building maps through multiple cameras in the VR field, or constructing three-dimensional maps in the field of automatic driving, or making 3D videos. [0003] The current multi-camera calibration method requires at least two cameras to have a common visual range, or to obtain ...
