Abstract
The utility model relates to an around view system calibration device based on vehicle position detection. The around view system calibration device comprises a calibration plate, a calibration plate controller, a vehicle controller area network (CAN) bus and an around view system controller. A position sensor is arranged on the calibration plate and connected with the calibration plate controller, and the calibration plate controller is connected with the around view system controller through the vehicle CAN bus. Compared with the prior art, the around view system calibration device has the advantages of being low in achieving cost, high in calibration precision, wide in application range and the like.
Description
Technical field
The utility model relates to a kind of vehicle viewing system caliberating device, especially relates to a kind of viewing system caliberating device detected based on vehicle location.
Background technology
The multiplex environment of the reversing in more complicated of backup camera, but the visual field of a camera is limited, in the situation that vehicle front side obstacle is more, usually adopt multiple cameras to form vehicle viewing system (BEV), for chaufeur provides vehicle 360 degree complete environment sensing information.The vehicle viewing system is mainly the image of taking by being arranged on vehicle many cameras all around, through aforesaid view transformation process obtain multiple virtual centered by vehicle birds-eye view vertically downward, and be spliced into a complete birds-eye view by composition algorithm.
Viewing system uses four cameras, its calibration process is more complicated and expensive, for obtaining accurate calibration result, need to utilize special-purpose demarcation station and demarcate place, all calibration methods all need vehicle to be calibrated is accurately alignd with the scaling board center, to obtain the Accurate Calibration result, for vehicle is accurately alignd with the scaling board center, demarcate usually and complete at four-wheel location station, problem is various for equipment on the station of four-wheel location, there is no the space of placing large-scale BEV scaling board too much.
The utility model content
The purpose of this utility model is exactly to provide a kind of viewing system caliberating device detected based on vehicle location of realizing that cost is low, stated accuracy is high, applied widely in order to overcome the defect that above-mentioned prior art exists.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of viewing system caliberating device detected based on vehicle location, it is characterized in that, comprise scaling board, scaling board controller, vehicle CAN bus and viewing system controller, described scaling board is provided with position transduser, this position transduser is connected with the scaling board controller, and described scaling board controller is connected with the viewing system controller by vehicle CAN bus;
When vehicle is sailed to after on scaling board, position transduser on scaling board is issued the scaling board controller by the location information of vehicle, the scaling board controller sends to the viewing system controller by the location information of vehicle, and this viewing system controller is demarcated vehicle in conjunction with the location information of vehicle.
Described scaling board is checkerboard configuration, is equipped with a position transduser in each gridiron pattern.
Described gridiron pattern is square structure, and its length of side is 30cm.
Described position transduser is ultrasonic transduter, optical sensor or infrared pickoff.
Described viewing system controller judges by vehicle position information whether vehicle arrives the accurate location of demarcation.
Described vehicle position information comprise vehicle coordinate figure and with the horizontal angle of scaling board.
Compared with prior art, the utlity model has following advantage:
1, realize that cost is low, no longer need expensive four-wheel fixing aid to carry out accurate positioned vehicle, just can obtain accurate calibration result;
2, stated accuracy is high, by position transduser, the accurate location of vehicle on scaling board detected, thereby has effectively improved stated accuracy;
3, applied widely, not only can be used for the viewing system demarcation of rolling off the production line, also can be used for the demarcation of other all cameras or sensor.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
Embodiment
As shown in Figure 1, a kind of viewing system caliberating device detected based on vehicle location, comprise scaling board 1, scaling board controller 2, vehicle CAN bus 3 and viewing system controller 4, described scaling board 1 is provided with position transduser 11, this position transduser 11 is connected with scaling board controller 2, and described scaling board controller 2 is connected with viewing system controller 4 by vehicle CAN bus 3; Described viewing system controller 4 judges by vehicle position information whether vehicle arrives the accurate location of demarcation.
When vehicle is sailed to after on scaling board 1, position transduser 11 on scaling board 1 is issued scaling board controller 2 by the location information of vehicle, scaling board controller 2 sends to viewing system controller 4 by the location information of vehicle, and this viewing system controller 4 is demarcated vehicle in conjunction with the location information of vehicle.
Described scaling board 1 is checkerboard configuration, is equipped with a position transduser 11 in each gridiron pattern.Described gridiron pattern is square structure, and the principle of design of gridiron pattern size is: single-sensor is undetected can not affect calibration result, and the gridiron pattern length of side in the present embodiment is 30cm.Described position transduser 11 is ultrasonic transduter, optical sensor or infrared pickoff.Described vehicle position information comprise vehicle coordinate figure and with the horizontal angle of scaling board.
