The processing terminal is based on first definition values and default definition values obtain the first difference, if first difference
Less than or equal to zero, then the camera calibration is completed, and the calibration rotating disk stops operating；
If first difference is greater than zero, the calibration rotating disk continues to rotate the camera lens according to the first direction and obtain
Second difference of the second definition values and default definition values out continues if second difference is less than first difference
The camera lens is rotated according to the first direction, until the difference of definition values and default definition values that the camera lens obtains is small
In equal to zero；
If second difference is greater than first difference, the calibration rotating disk rotates the camera lens according to second direction,
The first direction is opposite with the second direction.
7. lens calibration method as claimed in claim 6, which is characterized in that the lens calibration device further includes video acquisition
Card, the calibration rotating disk rotate the camera lens according to first direction, the image that the camera acquires are sent to the place
The step of reason terminal calculates the first definition values further include:
The imaging signal that camera acquires is converted digital signal by the video frequency collection card；
The processing terminal handles the digital signal to obtain the first definition values.
8. lens calibration method as claimed in claim 6, which is characterized in that if first difference is greater than zero, institute
Calibration rotating disk is stated to continue to rotate the camera lens according to the first direction and obtain the second definition values and default definition values
The second difference continue to rotate the camera lens according to the first direction if second difference is less than first difference
The step of further include:
The lens calibration device is according to the preset time interval acquired the definition values of the camera.
9. lens calibration method as claimed in claim 6, which is characterized in that the second driving assembly driving is according to the school
Calibration rotating disk rotation described in quasi instruction completes the calibration to the camera clarity to drive the camera lens to rotate:
The processing terminal responds the instruction calibrated to definition values, wherein includes the camera shooting of required calibration in described instruction
Head clarity.
10. a kind of camera lens calibration system, which is characterized in that the camera lens calibration system includes the processing terminal and mirror of communication connection
Head calibrating installation, the system carry out lens calibration using the described in any item lens calibration methods of claim 1-9.
