Automatic tracking and aiming high-precision numerical control cradle head

Abstract

The invention discloses an automatic tracking and aiming high-precision numerical control cradle head. The automatic tracking and aiming high-precision numerical control cradle head comprises an image identification module, a tracking control module and a servo module, wherein the image identification module is used for cutting and identifying an image acquired by a camera and determining position coordinates of a target tracked and aimed by the cradle head; the tracking control module comprises a motion control module and a laser positioning module, the motion control module finds the tracked target by controlling the movement of the cradle head, and the laser positioning module emits lasers with different powers to aim at the target; and an input interface of the servo module is connected with an output interface of the image identification module, receives the position coordinates of the tracked and aimed target, and responds to and outputs the rotating speed and angle of a servo motor from the output interface according to the received position coordinates. A hollow speed reducer rotating platform and the servo motor direct drive mode are adopted, delay in multi-stage gear transmission is avoided, all the modules are coordinated and matched with one another, the automatic tracking and aiming function can be achieved, precision is high, and the real-time tracking effect is good.

Description

technical field [0001] The invention relates to a high-precision numerically controlled pan-tilt for automatic tracking and aiming, which belongs to the field of laser pan-tilts. Background technique [0002] With the rapid development of computer technology and the rise of artificial intelligence, computer vision, as a product of the combination of the two, is booming. Computer vision can process and analyze the visual information collected by the imaging system through computers and related equipment, and simulate biological vision to complete a series of identification, detection, and tracking tasks. Among them, visual tracking technology is an important research field of computer vision, and has broad application prospects in military, manufacturing, medical and other fields. [0003] As a support device for a fixed imaging system, the pan / tilt's rotation control performance plays a decisive role in the tracking effect of the system. Most of the tracking pan / tilts curr...

AI Technical Summary

Problems solved by technology

Most of the tracking pan / tilts currently on the market are multi-stage gear reduction structures. Machining errors and assembly errors will cause gaps between the gears. There is a delay in the drive, and it is difficult to achieve real-time tracking

In addition, the structure of the turntable and encoder of the gimbal has low stepping accuracy and poor tracking effect
