The present invention relates to a PTZ correction method, belonging to the technical field of PTZ calibration. Firstly, the image of a preset position is collected as a template image, and an azimuth, a pitch angle and a camera zoom ratio at that time are recorded; then the template image is subjected to modeling, and the outline of a target object is extracted with the center point of the template image as a center; then a PTZ and a camera are set to carry out image collection with the preset position of the template image in collection, the collected image and the template image are compared, and the offset pixel of the target object is calculated; and finally the PTZ offset angle is calculated according to the obtained offset pixel, and the PTZ offset angle is added to the PTZ preset position, and a corrected absolute angle is obtained. The machine vision technology is used to identify a target point, the PTZ posture can be quickly adjusted, an external sensor is not needed, the alignment precision of the PTZ is improved, and the target deviation error in shooting the image is reduced.

The invention relates to an infrared temperature measurement system holder position calibration method based on visible light image registration. The method comprises the following steps: (1) pre-acquiring a standard image of a preset position through a visible light video probe, and storing the standard image as a template image; (2) acquiring a current image of the preset position through the visible light video probe when a holder returns to the preset position again, and calling the current image a target image; (3) acquiring the position deviation between the template image and the target image, judging whether the position deviation is greater than a predetermined threshold, executing step (4) if the position deviation is greater than the predetermined threshold, or returning to step (2); and (4) generating a compensation parameter through a holder controller according to the position deviation, making the holder rotate according to the compensation parameter, and calibrating the holder to make the holder return to the preset position. Compared with the prior art, the method of the invention has the advantages of less repeated operation, high image matching speed, effective realization of temperature measurement position correction, and the like.

The invention discloses a dome camera preset position correction method and a correction device, which can be used to optimize the operation system of the dome camera. The correction method is characterized in that when offset of a preset position occurs during real-time monitoring of a target object, an offset image can be acquired and stored, and then the offset characteristic data of the offset image can be extracted; the above mentioned offset characteristic data can be compared with the original characteristic data of the original data of the pre-stored corresponding preset position, and the preset position can be corrected according to the acquired comparison result. When the preset position is offset, the preset position can be corrected effectively, and therefore the correctness and the validity of the monitoring of the dome camera can be guaranteed, and the manual maintenance of the dome camera can be reduced.

The invention relates to the field of robot positioning, in particular to a rapid positioning compensation method. The rapid positioning compensation method includes that a robot moves to a photograph site, and a standard template is established; the robot rotates along a preset axis, and rotation angle of a camera and offset coordinates of a camera center which the rotation angle corresponds to during rotation are collected; according to the rotation angle, the offset coordinates and the standard template, the deviation of the offset coordinates and the standard template is calculated, and a corresponding relation between the rotation angle and the deviation is established; a compensation form of the rotation angle and the deviation is established by means of an interpolation method, compensation is performed on positioning of the camera and the robot, rapid compensation of coordinates between the robot and the camera can be achieved, and the implementation method is simple.

The invention provides a method for improving the presetting bit accuracy of a pan-tilt camera. The method comprises the following steps that (1) compensation is conducted on a mechanical error when a pan-tilt is operated; (2) when a presetting bit is set, a current image needs to be obtained and stored as a template image; (3) a coarse positioning step and a fine positioning step are conducted, wherein (1) the presetting bit is called and the pan-tilt is moved to the position near a presetting bit point; (2) the current image is obtained, deviation of the current image and the template image is converted into pain-tilt displacement, error compensation is reckoned, the current position is corrected. The method for improving the presetting bit accuracy of the pan-tilt camera has the advantages that compensation is conducted on the pan-tilt mechanical error and the presetting bit accuracy is improved; through the match of the current image and the template image, the pan-tilt displacement compensation amount is calculated and the presetting bit accuracy is further improved; the method is also suitable under the condition that pan-tilt control lacks displacement feedback of a sensor, the pan-tilt structure scheme is simplified, and cost is reduced.
