Row record has the program of correlative code of the embodiment of the present invention, to test camera to be measured.
Alternatively, the controller control first actuator 130 drive the second cross beam 120 so that the lamp plate 150 with
Before the distance between the camera to be measured is pre-determined distance, the controller can obtain the pre-determined distance first.Wherein, the control
Device processed can obtain the pre-determined distance in several ways.For example, the pre- of the camera to be measured can be stored inside the controller
If distance.In another example the controller can obtain the pre-determined distance by other equipment or system.For another example the controller can
For obtaining the nearly focal length of the camera to be measured；According to the nearly focal length, the pre-determined distance of the camera to be measured is determined.
More than, describing the controller with reference to Fig. 1 and Fig. 2 can control the first actuator 130 and the second actuator 170 to drive
Dynamic lamp plate 150 moves, so that the test equipment 100 can be tested camera to be measured corresponding to different nearly focal lengths, energy
The enough efficiency and quality for improving test.Wherein, the test equipment 100 can be tested many kinds of parameters of camera to be measured.
For example, the test equipment 100 can be tested the installation site of the camera to be measured.Ideally, the shooting to be measured
Head meets installation standard in the installation site of capture apparatus.However, due to factors such as techniques, camera to be measured is on capture apparatus
Installation be likely to occur off normal (i.e. deviation post), so as to cause shooting quality problem.
Alternatively, the controller of the test equipment 100 can be also used for：
Based on the pre-determined distance, the lamp plate image with mark point that the camera to be measured is shot is obtained；
According to the lamp plate image, actual position information of the mark point in the lamp plate image is determined；
According to the actual position information and reference position information, the installation position of the camera to be measured on capture apparatus is determined
The off normal size put and off normal direction.
Specifically, the test equipment 100 can test installation of the camera to be measured on capture apparatus by controller
Whether position meets installation standard.Wherein, actual position information of the mark point in lamp plate image can refer to：In practice should
Positional information in the lamp plate image of the camera shooting of capture apparatus where mark point；The reference position information can refer to：
If camera meets installation standard, the lamp plate image acceptance of the bid of the camera shooting of the capture apparatus in the installation site of capture apparatus
Remember the positional information (can be ideal position information or theoretic positional information by the reference position comprehension of information) of point.Example
Such as, if the installation site of the camera of capture apparatus meets standard, mark point A should position in the lamp plate image of capture apparatus shooting
At the X position of the lamp plate image；In fact, mark point A is located at the Y of the lamp plate image in the lamp plate image of capture apparatus shooting
Opening position, the test equipment 100 can determine that the camera is relative according to the positional information of X position and the positional information of Y location
Off normal size and off normal direction in the capture apparatus, the test equipment 100 can be used for the installation for detecting the camera to be measured
Situation.
Therefore, the test equipment 100 of the embodiment of the present invention can be to camera to be measured on capture apparatus by controller
Installation site carry out off normal test, off normal size and the off normal direction of the installation site of camera to be measured are obtained, in order to pacify
Install standby or other equipment and the camera to be measured is handled according to the off normal size and off normal direction and (such as carry out installation position
The correction put), it is possible to increase the installation accuracy of the camera to be measured, improve the shooting quality of camera to be measured.If for example, survey
The camera to be measured that examination equipment 100 is tested off normal be present but off normal size is not less than pre-determined threshold, illustrates the camera to be measured
Off normal belong to qualified installation in the scope that can be received, the camera to be measured.In another example if the test equipment 100 test
The off normal size of camera to be measured exceedes pre-determined threshold, illustrates that the off normal of the camera to be measured is serious, it is necessary to the shooting to be measured
Position of the head on camera is adjusted, to ensure the shooting quality of camera to be measured.Further, the off normal size and partially
Position direction can also be used to correct the installation site of other cameras, in order to improve the installation accuracy of other cameras, so as to
Improve the shooting quality of other cameras.Further, the off normal size of the test equipment 100 acquisition and off normal direction are to same
The capture apparatus of one model is calibrated, it is possible to increase the shooting uniformity of the capture apparatus of same model.
In embodiments of the present invention, the controller can obtain the reference position information in several ways.For example, the control
Corresponding reference position information can be stored inside device processed；In another example the controller can be obtained by other equipment or system
The reference position information；For another example the controller is used for the reference chart of the lamp plate 150 of the camera shooting for obtaining reference device
Picture；According to the position of mark point in a reference image, the reference position information is determined.It is assumed that D1 is reference device, the controller
The reference picture of the lamp plate 150 of D1 shootings is obtained, the positional information of the mark point in a reference image can be used as the reference
Positional information.
The controller can obtain the reference position information in several ways, in order to which the test equipment 100 is according to this
The off normal of the reference position acquisition of information camera to be measured.
Above, the off normal can be determined according to reference position information and actual position information by describing the test equipment 100
Size and off normal direction.Wherein, the actual position information and the reference position information can be comprised at least with the situation of sowing：
Situation one,
The actual position information includes the mark point in the lamp plate image to be included to the vertical line section at the edge of the lamp plate image
Pixel actual quantity, the reference position information includes reference number amount, and the controller is specifically used for：
According to the actual quantity and this refer to quantity between difference, determine the off normal size；
According to the position relationship between the edge of the mark point and the lamp plate image in the lamp plate image, the off normal side is determined
To.
Specifically, this can refer to reference to quantity：If camera meets installation standard in the installation site of capture apparatus,
The quantity for the pixel that the vertical line section includes.For example, if the installation site of camera to be measured meets standard, the lamp of capture apparatus shooting
Mark point A should include N number of pixel, the reference number of the pixel to the vertical line section between the left margin of the lamp plate image in plate image
Measure to be N number of；In fact, mark point A is to the vertical line between the left margin of lamp plate image in the lamp plate image of camera to be measured shooting
Section includes N+M pixel, and M is the positive integer more than 1 or equal to 1, then the actual quantity is N+M.Compared with reference quantity,
The vertical line section of mark point A to the left margin of lamp plate image adds M pixel.The controller can be according to camera installation position
Corresponding relation between the off normal amount and pixel quantity put, determine the installation site of camera to be measured corresponding to M pixel quantity
Off normal size, off normal direction of the camera relative to capture apparatus can be determined according to the position relationship at mark point and X edges
For left side.
