The invention relates to an installation method of an optical imaging sensor in machine vision, which is applied to the field of optical instrument installation and measurement. It includes the following steps: first, the optical imaging sensor is installed in a fixed housing with a reference mirror, and then the coordinates between the optical imaging sensor coordinate system, the V-STARS observation coordinate system, theodolite system coordinate system and the reference mirror coordinate system are determined through observation and calculation The conversion relationship, and the conversion relationship between the optical imaging sensor coordinate system and the reference mirror coordinate system is used as the basis of installation to install the application object. The invention breaks through the technical problem of physical representation of the optical coordinate system, and solves the problem of precise installation of the optical imaging sensor.
Description
technical field [0001] The invention belongs to the field of installation and measurement of optical instruments and equipment. Background technique [0002] In the existing vision theory and vision technology, the coordinate system of the optical imaging sensor studied is a virtual coordinate system. Therefore, in the installation of the optical imaging sensor, since the optical coordinate system cannot be monitored at any time, the installation result can only be detected by means of calibration after installation; and because the optical coordinate system of the optical imaging sensor and the coordinates of the installed casing are unknown It is also very difficult to rely on mechanical processing to ensure the design installation value, which will inevitably cause deviations between the installation results and the design installation value. [0003] At present, there is no detailed description in domestic and foreign literature on the installation method of the optical...
