Movement speed control method for cable-driven camera robot

Abstract

The invention discloses a movement speed control method for a cable-driven camera robot. The method includes the steps of initializing a control device, selecting a control mode, processing received data, controlling a camera to move, stopping movement of the camera and the like. Movement speed of the camera robot is controlled in a point-motion control mode and a handle control mode; in the point-motion control mode, the movement speed of the camera robot is increased from zero to a constant speed to keep the camera robot moving at the constant speed by controlling a point-motion knob; in the handle control mode, the movement speed of the camera robot changes with change of rocking angle of a handle by controlling the handle, a control program of a camera robot actuator controls telescoping speed and length of four cables of the camera robot according to a transmitted speed vector, and the camera robot is controlled to be in stable three-dimensional motion in the specified space according to the specified speed vector.

Description

technical field [0001] The invention belongs to the field of mechanical technology, and further relates to a method for controlling the motion speed of a cable-drawn camera robot in the field of mechanical motion control. The invention can realize the stable movement of the camera robot pulled by the cable in any direction at any speed within a specified space range. Background technique [0002] Traditional aerial photography is realized through equipment such as rocker cameras, helicopter aerial photography systems, and crank-arm elevator camera systems. These shooting methods are subject to certain conditions in terms of shooting angle and area. The lifting height of the rocker camera is very limited, and it can only be fixed in a small radius for shooting. During aerial photography by helicopter, due to the influence of noise and vibration, only long-distance shooting can be carried out, which cannot reflect the details of the subject, and the cost of aerial photograph...

AI Technical Summary

Problems solved by technology

The disadvantages of the control method provided by this patent application are: in the process of controlling the movement of the controlled object, the moving speed is not effectively controlled, and the controlled object may have problems of impact and motion instability during the movement process

The disadvantage of the control method disclosed in this patent is: in the process of using the mouse to control the movement of the camera, the mouse can only move in two-dimensional plane, so there will be limitations when controlling the camera to move in three-dimensional space

The deficiency in this patent is: there is no specific implementation method for controlling the change of camera movement speed, and how to realize the smooth change of camera speed
