Method, device and equipment for determining internal reference of PTZ (Pan/Tilt/Zoom) camera device and storage medium

Abstract

The invention provides a method, device and equipment for determining an internal reference of a PTZ camera device and a storage medium, and the method comprises the steps: obtaining target image information which is shot by the PTZ camera device and is related to a target, and enabling the target to be disposed on unmanned plane equipment; determining first coordinate information of image feature points in the target image information according to the target image information; obtaining second coordinate information of target feature points in the target in a target coordinate system, wherein the target feature points correspond to image feature points of the target image information; and determining the internal reference of the PTZ camera device based on the first coordinate information and the second coordinate information. The automatic calibration of the PTZ camera device is realized by using the unmanned aerial vehicle equipment, and the current situation of tedious manual calibration of equipment one by one is replaced, so that the calibration process is simpler and more flexible, and the precision is superior to that of an automatic calibration result without a calibration object.

Description

technical field [0001] The present application relates to the field of communication technology, and in particular to a method, device, computer equipment and storage medium for determining internal parameters of a PTZ camera device. Background technique [0002] PTZ camera device refers to a surveillance camera with a PTZ control pan / tilt. PTZ is the abbreviation of Pan / Tilt / Zoom. The middle of the surveillance camera refers to the three dimensions of pan / tilt control: left and right rotation, up and down pitch, and zoom. Most of the current urban management systems rely on the video images of the multi-channel monitoring network and the ground duty personnel to monitor the key areas of the city. Traditional surveillance cameras only have image acquisition and basic PTZ pan / tilt control functions, and they are independent of each other. Ordinary PTZ camera devices have no calibration internal parameters, so they do not have spatial computing capabilities. Moreover, it is ...

Problems solved by technology

Ordinary PTZ camera devices have no calibration internal parameters, so they do not have spatial computing capabilities

Moreover, it is difficult for the PTZ camera devices in the city to ensure the overlap of the field of view, so the spatial constraint relationship between multiple camera devices cannot be determined by itself.
