Parameter calibration method and device of camera device, medium and electronic equipment

Abstract

The invention discloses a parameter calibration method and device of a camera device, a medium and electronic equipment, wherein the method comprises the steps: respectively carrying out the feature point extraction operation of a first image shot by a to-be-calibrated camera device and a second image shot by a reference camera device, obtaining a plurality of first feature points in the first image and a plurality of second feature points in the second image; performing feature point matching processing on the plurality of first feature points and the plurality of second feature points to obtain a plurality of matched feature point pairs; and determining external parameters of the to-be-calibrated camera device according to the plurality of matched feature point pairs and the distance between the to-be-calibrated camera device and the reference camera device. According to the technical scheme provided by the invention, the external parameters of the camera device can be conveniently and accurately recalibrated. For smart driving application, the safety of vehicle driving can be improved.

Description

technical field [0001] The present disclosure relates to parameter calibration technologies, and in particular, to a parameter calibration method of an imaging device, a parameter calibration device of an imaging device, a storage medium, and electronic equipment. Background technique [0002] In applications such as ADAS (Advanced Driving Assistant System, Advanced Driving Assistance System), it is usually necessary to use multiple camera devices. For example, multiple camera devices are installed on the vehicle to realize functions such as automatic cruise or intelligent driving. [0003] During the use of multiple camera devices, the relative positions of the camera devices may change. For example, factors such as vibration of the vehicle, high temperature and severe cold inside the vehicle may cause the screws fixing the camera device to loosen, thereby changing the relative position between the two camera devices. For another example, the replacement of the camera dev...
