With the development of monitoring field electronic technology, the design direction of various products is all detail towards remote sharpening
Direction develop, big multiplying power monitoring device is come into being, but multiplying power more bigger it is easier by strut shake or it is pneumatic influence,
Under the influence of these factors, so that the video jitter that machine core sensor is obtained under big zoom is strong, the sense organ of user, shadow are influenced
Ring accuracy of the back-end platform to video analysis.
Summary of the invention
Based on this, a kind of mechanical stabilization long-focus video camera is proposed, the technical solution adopted is as follows:
A kind of machinery stabilization long-focus video camera, including big magnification camera machine core, big magnification camera machine core are mounted on
On stabilization bracket, stabilization bracket connects stabilization mechanism, and the stabilization mechanism includes DC brushless motor and multiaxis gyroscope, described
Stabilization bracket includes round rectangle bottom plate, and the bottom plate is equipped with several circular holes, and the side of the bottom plate has for connecting direct current
The top of the side plate of brushless motor, the side plate is equipped with restoring board, and restoring board is perpendicular with side plate, and restoring board is far from side plate side
For arc-shaped recess, positional symmetry sets that there are two notches at arc-shaped recess.
Further, the smooth of the edge of the arc-shaped recess.
Further, the side plate is rectangular slab, and the width of rectangle is less than the side length of side plate position side bottom plate.
Further, the stabilization mechanism includes DC brushless motor and multiaxis gyroscope, and multiaxis gyroscope passes through sampling,
Current camera position and amount of jitter are obtained, control module calculates position deviation according to amount of jitter, and control module is controlled by PID
DC brushless motor processed carries out real-time angle Reverse Turning Control to machine core position.
Further, wherein DC brushless motor includes magnetic encoder device, and motor real time position is read by magnetic coder
It takes, and sends control module to.
Further, DC brushless motor real-time control electric current, after more resistance samplings, by three control lines, directly
By current value feedback to control module.
Compared with prior art, the beneficial effects of the present invention are:
1. and the compensation operation of motor is carried out by pid algorithm, picture can carry out electrodeless compensation, vision in shake
Upper imperceptible any variation, response speed are significantly faster than the video optimized algorithm of electronic flutter-proof.
