Embodiment Construction
[0031] The present invention will be further described below with reference to the accompanying drawings and examples, and the modes of the present invention include but are not limited to the following examples.
[0032] This embodiment is a camera calibration tool designed to improve the efficiency of camera quality inspection, and can be applied to the quality inspection process of the fanbot robot developed by the applicant. see figure 1 , when the camera calibration tool is in use, the entire tool is placed on a horizontal platform, so the horizontal and vertical in the "horizontal steering assembly" and "vertical steering assembly" described below are based on this. With reference to the description, when the tool is installed on other different workstations such as a vertical wall, its corresponding reference surface is changed to a wall (ie, its installation surface). The tooling in this embodiment mainly includes a calibration head 1, a head support 2, a calibration ...

The invention relates to a camera calibrating device and particularly discloses a camera calibrating pan-tilt and a calibrating tool comprising the calibrating pan-tilt. The calibrating pan-tilt is used for installing a to-be-calibrated camera, and comprises a pan-tilt base, a horizontal steering assembly arranged on the pan-tilt base, a vertical steering assembly arranged on the horizontal steering assembly, and a camera fixing assembly fixed to the vertical steering assembly; and the camera is fixed to the camera fixing assembly. The calibrating pan-tilt is simple in structure and ingeniousin design, the angle of the camera can be adjusted in the horizontal direction and the vertical direction, and fast disassembling and assembling of the camera and replacing of various cameras can be achieved. The calibrating tool comprise the calibrating pan-tilt, a pan-tilt support, a calibrating plate assembly and calibrating tracks, and has the beneficial effects of being simple in structure, reasonable in design, easy to operate, more compatible, capable of improving the quality inspection efficiency in the camera production process and the like.
Description
technical field [0001] The invention relates to a camera calibration device, in particular to a camera calibration pan-tilt and a calibration tool including the calibration pan-tilt. Background technique [0002] In the virtual reality multi-target tracking technology, in order to determine the relationship between the spatial position of the target object and its imaging in the image, the geometric model of the camera imaging must be established. These geometric model parameters are the camera parameters, and the process of solving the parameters is called Camera calibration. Before the camera leaves the factory, the camera needs to be calibrated to obtain the calibration information of the camera, so that the camera can process the image according to the calibration information, so that the processed image can restore the object in the three-dimensional space. Existing camera calibration tooling for calibrating cameras such as robots and mobile phones usually includes a c...
