Abstract

The invention discloses a presetting bit precision automatic testing system and a testing method thereof. The presetting bit precision automatic testing system comprises a testing system unit, tested equipment and template placing location unit. The testing method comprises the steps of: placing a calibration template, and adjusting zooming times of a camera so that the calibration template occupies an appropriate field-of-view scope of a lens; inputting a distance into a control module for setting; clicking calibration to run the calibration template, so as to obtain a transformation model of image pixels and spatial positions; setting a presetting bit for acquiring an image; recalling the presetting bit for acquiring an image; matching the images of the presetting bit and calculating a pixel deviation; calculating a rotation angle deviation of the tested equipment; testing presetting bit deviations of a uniform presetting bit under different control; and testing presetting bit deviations at different positions. Compared with the prior art, the presetting bit precision automatic testing system based on image processing disclosed by the invention is simple and rapid in system installation, has automatic testing operation, is more complete in tests, and achieves high test precision in the actual application.

Description

technical field [0001] The invention belongs to the technical field of preset position precision testing, and in particular relates to a preset position precision automatic testing system and a testing method thereof. Background technique [0002] In the field of video surveillance, pan / tilt and dome cameras are widely used, among which the accuracy of preset positions is an important evaluation parameter, and the demand for accuracy and convenience of accuracy testing is increasingly urgent. The current existing preset position accuracy test system generally equips the equipment to be tested with a preset position mapping point device, obtains each preset position mapping point through a data acquisition device to obtain the number of preset position deviation pixels, and then installs it according to the actual The position calculates the deviation distance of the horizontal and vertical direction of the preset position. [0003] In the above-mentioned test system, the in...
