Consult Fig. 1 to Fig. 4, for solving the problems of the technologies described above, the utility model adopts following technical scheme to be achieved.The universal type centering one-dimension calibration target of automobile pattern vision detection system provided by the utility model includes camera tripod, video camera, unique point mark, one-dimension calibration target rod, universal joint and cross square steel.
Video camera is placed on the upper surface of camera tripod, threaded hole bottom video camera is fixedly connected with the stud screw thread of camera tripod upper surface, bolt is fixedly connected with the threaded hole screw thread of cross square steel end face through four manholes of universal joint bottom circular steel plate, three unique points mark is equidistantly pasted onto in the plane of one-dimension calibration target rod side, and the axle that the borehole jack of the bottom of one-dimension calibration target rod is contained in universal joint top is tightly fixed with the axle on universal joint top and is connected.
Unique point described in technical scheme is designated the circular paster with gridiron pattern pattern.
One-dimension calibration target rod described in technical scheme is processed into by round steel pipe, and the side of steel pipe processes a plane.
The circular steel plate that universal joint described in technical scheme is welded with bottom axial end by cardan (hookes)universal joint is made, circular steel plate symmetrical machining four manholes.
Cross square steel described in technical scheme is welded by three blocks of square steel and makes, and two blocks of short square steel are symmetrically welded at the side, middle part of rectangular steel, and cross square steel upper surface processes four threaded holes.
The beneficial effects of the utility model are:
(1) because the constraint that one-dimension calibration thing provides freely is not enough to solve all parameters of camera, the utility model makes the bottom through hole of 1-dimension drone rod and the axle wringing fit of universal joint one end, the universal joint other end is fixed on cross square steel end face, thus the centering achieving the excellent center around fixing universal joint of 1-dimension drone is freely rotated, and meets the constraint condition that 1-dimension drone solves camera interior and exterior parameter.
(2) critical part of the present utility model adopts standard steel section to process, and first, standard steel section output is large, and machining operation is few, and production cost is lower; Secondly, as the important accessory of surveying instrument, adopt standard steel section to have certain intensity, can be indeformable in Long-Time Service, ensure the precision measured, the requirement of national standard to measuring accuracy can be met.
