[0003] Using the above-mentioned detection target, the local sharpness of the ISO12233 image sharpness test card has nothing to do with the installation angle of the industrial camera sensor. The industrial camera sensor is adjusted, resulting in the installation accuracy of the industrial camera sensor and the consistency of the product cannot be guaranteed

The invention discloses a target used for industrial camera detection and relates to the industrial camera detection technology field. The target comprises a center cross target arranged at the centerof the target and four edge cross targets close to the top point position of the target. The center cross target is a symmetrical structure. The edge cross targets are symmetrically arranged about atarget center line. The target lines of the center cross target and the edge cross targets are dot and dash lines with an equal length. The intersection point of the target lines of the center cross target is the center point of the target. The intersection point of the target lines of the edge cross targets is close to the top point of the target. The structures of the target lines and the positions of the cross targets can be associated, and the installation of a corresponding position industrial camera sensor is adjusted. In the technical scheme of the invention, the structures of the target lines and the positions of the cross targets are associated, through analyzing a target line length, a line width and a definition, the installation angle of an industrial camera sensor and the backintercept of an industrial camera are adjustes, which is conducive to improving the consistency and the product quality of industrial cameras in mass production.
Description
technical field [0001] The invention relates to the technical field of industrial camera detection, in particular to a target used for industrial camera detection. Background technique [0002] The existing method of detecting whether the installation angle of the industrial camera sensor meets the requirements is to take the ISO12233 image definition test card, and then detect the resolution of the image after shooting to obtain the definition of the camera to be inspected, and then calculate the obtained definition Compared with the set standard, if the definition meets the set standard, it is determined that the installation angle of the industrial camera sensor meets the requirements, otherwise, reinstall the industrial camera sensor. [0003] Using the above-mentioned detection target, the local sharpness of the ISO12233 image sharpness test card has nothing to do with the installation angle of the industrial camera sensor. The industrial camera sensor is adjusted, res...
