Abstract

The invention provides a calibration method of an image acquisition device. The calibration method of the image acquisition device comprises the following steps: receiving an image uploaded by a userand displaying the image on a user interface, wherein the image is acquired by the image acquisition device; responding to an input operation of a user, and obtaining two parallel datum lines in the image; calculating vanishing point coordinates according to the two parallel datum lines; calculating a yaw angle and / or a pitch angle according to the vanishing point coordinates, a preset focal length and a preset principal point offset, wherein the preset focal length and the preset principal point offset are the focal length and the preset principal point offset of the image acquisition devicewhen the image acquisition device acquires the image; and outputting calibration information of the image acquisition device. In addition, the invention further provides computer equipment and a storage medium. A user only needs to adjust or draw two datum lines which are not parallel to the imaging plane of the image in the image, special professionals are not needed for processing, the application range of user groups is wider, and operation is simpler and more convenient.

Description

technical field [0001] The invention relates to the technical field of imaging, in particular to a calibration method for an image acquisition device, computer equipment, and a storage medium. Background technique [0002] In the vehicle-road coordination scenario, the camera is usually used as a road test perception device to perceive information such as the position of vehicles, pedestrians and other objects. However, during the installation or working process of the camera, the position may change due to factors such as operational problems during installation, wind, external impact, or human adjustments. The camera extrinsic parameters determine the relative position between the camera coordinate system and the world coordinate system relationship, so camera extrinsics, such as yaw and / or pitch angles, need to be corrected. However, the existing calibration techniques and tools are all geared towards algorithm personnel, and installation engineers or non-professionals c...
