A device for realizing the angle return of the pan-tilt

Abstract

The invention belongs to the video monitoring field, in particular to a method for realizing the angular rotation of a tripod head, comprising a boundary limiting module, a zero-angle position module, a singlechip control module and a rotation angle display module. The boundary limiting module is used for fixing the tripod head in a motion range of a certain direction and generating a hop signal of the level; the zero-angle position module is used for confirming the physical position displaying zero angle and generating a hop signal of the level; the singlechip control module is used for processing the received hop signal, finishing the initialization of needed parameters, calculating the rotary angle and outputting the rotation angle; and the rotation angle display module is used for receiving the information of the rotation angle and outputting the information to display equipment for display. By utilizing the structures of the singlechip control module, and the like, the invention realizes the self adaption of the angular rotation; by the arrangement of the zero-angle position module, the feedback angle can be repeatedly calibrated to improve the accuracy of the feedback data; and any positive and negative angle range can be adjusted according to different mounting positions of the zero-angle position module.

Description

technical field [0001] The invention belongs to the field of video monitoring, and in particular relates to a device for realizing the return transmission of the angle of a pan-tilt. Background technique [0002] With the continuous development of security products, people are no longer satisfied with simply controlling products such as pan / tilts, shields, and high-speed balls, but hope to have enough feedback information to let them understand the current operating status of the products more intuitively. , or use these status feedback information to conduct research on other projects, so that our security products can develop to a wider field and a deeper level, not just limited to the current application field. [0003] Angle status feedback, that is, the angle return function, is a function developed earlier and widely used. It can accurately reflect the current product position status, help the system to accurately locate the target, accurately search for a certain posi...

Problems solved by technology

[0005] The purpose of the present invention is to provide a device for realizing the return of the angle of the pan / tilt, aiming at solving the problem that the correct implementation of the commonly used angle return method must know the theoretical installation angle, and the limit device must be installed accurately to ensure the theoretical and The actual horizontal position of 0 degrees coincides, so once the installation angle is required to change, the program needs to be revised again, which is very inflexible to use; if there is a deviation during the installation process, the feedback data still has errors
