Abstract

The present application discloses a calibration template, a template detection method, a device and a terminal. The calibration template includes at least one calibration circle group and at least three positioning circle groups, the centers of the at least three positioning circle groups are not located on the same straight line, each calibration circle group includes at least two calibration circles with the same center, and the same calibration circle At least two calibration circles in the group form a ring, and the color of the ring is different from that of the adjacent area; each positioning circle group includes at least two positioning circles with the same center, and at least two positioning circles in the same positioning circle group form Ring, the color of the ring is different from the adjacent area; each positioning circle group includes the first feature circle and the second feature circle, the radius of the first feature circle is not equal to the radius of the positioning circle in the positioning circle group, the second The radii of the two characteristic circles are not equal to the radii of the calibration circles in each calibration circle group. The calibration template disclosed in the present application is not easily disturbed by the external environment, which improves the accuracy of template detection.

Description

technical field [0001] The present disclosure relates to the technical field of visual measurement, and in particular to a calibration template, a template detection method, a device, and a terminal. Background technique [0002] Shooting devices such as cameras and video cameras can record instantaneous images, and are widely used in daily life and work. In order to understand the performance of the camera, it is necessary to obtain the parameters of the camera, and the process of solving the parameters of the camera is called calibration. [0003] In the traditional technology, calibration usually adopts a two-dimensional plane calibration method, which includes the following steps: first, select a calibration template, the calibration template is a two-dimensional plane with a fixed pattern pattern, and the calibration module contains calibration points ; Then, use the photographing device to take pictures of the calibration template from different positions and angles, ...
