Abstract

The invention provides a method and a device for verifying calibration parameters of a camera and an electronic device. The method comprises: acquiring images obtained by shooting a calibration objectthrough all cameras; correcting each image by adopting the calibration parameters to obtain each corrected target image; determining homonymy points from each target image; and according to the homonymy points in each target image, judging whether the calibration parameter meets a verification index or not. According to the application, since the images obtained by shooting the calibration objectby the cameras are analyzed to verify the subsequent calibration parameters, the deviation condition of the calibration parameters during imaging application can be visually reflected, so that the calibration parameters are verified more accurately, and the verification effect of the calibration parameters is improved.

Description

technical field

[0001] The present application relates to the technical field of electronic equipment, in particular to a method, device and electronic equipment for verifying calibration parameters of a camera. Background technique

[0002] Camera calibration is to obtain the internal and external parameters of the camera. When using the camera for imaging, the pre-calibrated internal and external parameters are used to map the object to be photographed from the three-dimensional world to the imaging plane of the camera for imaging. In the process of practical application , in order to ensure the subsequent imaging effect, after pre-calibrating the camera, it is necessary to verify the internal and external parameters obtained through calibration.

[0003] In related technologies, when verifying the internal and external parameters obtained by calibration, random noise is generally added to the original internal and external parameters of the camera, and then the internal a...
