Abstract

The embodiment of the invention provides a lens distortion parameter adjustment method and device and a camera shooting device. The method includes the steps of selecting adjustment modes which include a calibration adjustment mode and a hand adjustment mode, adjusting a spin button by hand to adjust the distortion degree of an image to be shot after calibrating the image to be shot if selecting the calibration adjustment mode, and otherwise, adjusting the spin button by hand to adjust the distortion degree of an image to be shot if selecting the hand adjustment mode. According to the lens distortion parameter adjustment method and device and the camera shooting device, in the calibration adjustment mode and the hand adjustment mode, a user adjusts only one parameter by hand, namely, the user adjusts the revision parameter through one spin button, therefore, the adjusting process is simple, and lens distortion can be effectively reduced.

Description

technical field [0001] Embodiments of the present invention relate to computer vision and image measurement technologies, and in particular to a lens distortion parameter adjustment method, device and camera equipment. Background technique [0002] Lens Distortion (Lens Distortion) is a general term for the inherent perspective distortion of optical lenses. It refers to the distortion caused by the perspective of the captured image. image quality is very poor. In the prior art, the geometric model of imaging is established by calibrating the parameters of the shooting device, such as a camera, a video camera, etc., and the parameters of the geometric model are adjusted to reduce lens distortion. The commonly used geometric models include single-parameter multiplication model, single-parameter division One-parameter models such as models and two-parameter models such as two-parameter multiplication models and two-parameter division models. [0003] Taking the single-paramet...
