Summary of the invention
The utility model is for realizing the present situation of automobile pose parameter being carried out to low cost detection at present, have employed a kind of measuring technique based on monocular vision, provide a kind of low cost, structure simple, be easy to operate, measuring accuracy is high, dirigibility is strong, dependable performance can meet the body of a motor car pose parameter detection system based on monocular vision of automotive check industry to automobile pose testing requirement.
Consult Fig. 1 to Fig. 4, for solving the problems of the technologies described above, the utility model adopts following scheme to be achieved.Body of a motor car pose parameter detection system based on monocular vision provided by the utility model comprises video camera, circular hole formula target plate and Magnetic gauge stand.
Video camera is placed in the horizontal plane, and circular hole formula target plate is placed in the field range of video camera, and two bolts are fixedly connected with the threaded hole screw thread of two Magnetic gauge stand end faces through two small circular through holes of circular hole formula target plate two ends symmetrical machining.
Circular hole formula target plate described in technical scheme is the square plate part that resin makes, the uniform processing of circular hole formula target plate one group of manhole, two ends symmetrical machining two small circular through holes of circular hole formula target plate.
Magnetic gauge stand described in technical scheme is dial gauge standard magnetic gauge stand.
The beneficial effects of the utility model are:
(1) intersection point of gridiron pattern target plate can only be identified when the utility model finds unique point for current existing detection system, the problem that when obtaining enough unique points, target plate area is excessive, provide a kind of directly can obtain circular hole under camera coordinate system quafric curve image thus obtained the pose parameter of body of a motor car by the planimetric coordinates matrix conversion be tied under camera coordinate system.Coupling due to a unique point can only obtain two equation of constraint about vehicle body pose, and the coupling of a quafric curve can obtain five equation of constraint about vehicle body pose, therefore can obtain higher measuring accuracy.
(2) the utility model detects light to calibration system quality for body of a motor car pose parameter, easy to carry, requirement is waited on the car surface that is fixed on that can be firm, Magnetic gauge stand is adopted target plate and vehicle body to be fixed together, can Fast Installation be realized and real-time pose change body of a motor car being detected, improve the real-time of test.
(3) the utility model detects light to calibration system quality for body of a motor car pose parameter, easy to carry, can be firm be fixed on the requirements such as car surface, adopt circular hole formula target plate, the center of each circular hole has good noise immunity, improves the precision that test is measured.
(4) Magnetic gauge stand that the utility model adopts is magnet base conventional in industry, and this magnet base can by the presence or absence of switch control rule magnetic, and suction is large, volume is little, quality is light, can resist the impact of extraneous factor, improves the accuracy detecting vehicle body pose parameter.
