Abstract

The invention discloses a calibration method and calibration device based on human-computer interaction and a storage medium. The method specifically comprises the following steps: enabling image acquisition equipment to acquire a first to-be-processed image containing a calibration plate at a current sampling position; calculating a first transformation parameter of the image acquisition equipment corresponding to the first to-be-processed image relative to the calibration plate; according to a preset sampling position and the first transformation parameter, calculating a translation relationship and a rotation relationship between the current sampling position of the image acquisition device and a preset sampling position, adjusting the image acquisition device to the preset sampling position based on an instruction generated by the translation relationship and the rotation relationship, acquiring a second to-be-processed image at the preset sampling position, and calculating camerainternal parameters and distortion parameters of the image acquisition device. According to the embodiment of the invention, the image acquisition equipment acquires the image at the preset sampling position in a man-machine interaction mode, the camera internal reference and distortion parameters of the image acquisition equipment are calculated, measurement is carried out without the assistanceof indirect measurement equipment, and accurate calibration of the image acquisition equipment is achieved.

Description

technical field [0001] The present application relates to the field of computer vision, and in particular to a calibration method, calibration device and storage medium based on human-computer interaction. Background technique [0002] As one of the important ways for computers to observe the objective world, cameras are often used in image measurement processes and machine vision applications. In order to determine the relationship between the three-dimensional geometric position of a point on the surface of a space object and its corresponding point in the image, a geometric model of camera imaging must be established, and these geometric model parameters are camera parameters. Under most conditions, these parameters must be obtained through experiments and calculations. This process of solving parameters is called multi-sensor calibration (or camera calibration). Whether it is in image measurement or machine vision applications, the calibration of camera parameters is a ...
