Embodiment Construction

[0028] In the invention, the camera robot is pulled by the cable control device to realize three-dimensional movement in space. The device is mainly composed of a user control cabinet, a PC and an actuator. The control cabinet is connected with the PC, which is used to send the speed vector generated by the user when shaking the direction handle or pressing the jog button to the PC; the PC is connected with the actuator, and the PC converts the speed vector sent by the control cabinet into The execution command of the actuator is sent to the actuator, and the actuator controls the camera robot to move at the specified speed and direction.

[0029] The camera robot in the present invention has two control modes: jog control mode and handle control mode. Select the jog or handle control mode according to the control speed requirements; if you choose the jog control mode, then switch the control mode knob to the jog control mode. In this mode, the moving speed of the camera robo...

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...
