Embodiment Construction

[0019] A preferred embodiment of the present invention is described as follows in conjunction with accompanying drawing:

[0020] Referring to FIG. 1 , the small airborne pan-tilt tracking control device 2 is applied to a micro unmanned aerial vehicle 1 carrying a camera to track a ground moving target 4 . The device 2 , the airborne platform 3 , the image processing module 6 and the wireless remote control communication module 7 are all loaded on the miniature unmanned aerial vehicle 1 . The airborne gimbal 3 can move in two degrees of freedom, it is driven by an integrated motor, and has a camera and an RS-232 control interface. Among them, 5 are ground control stations. The function of this device 2 is to collect and process the attitude angle and angular velocity information of the aircraft, then fuse the tracking target image information sent by the image processing module 6, and calculate the moving angles of the airborne gimbal in two directions through a certain track...

Abstract

This invention relates to a small load trace and control device, whose circuit is to adopt SPI series connection between one main control single machine and one assistant single machine, wherein, the four series mouths are through RS-232 level conversion chip with one connected to electron panel and other three as outer series communication interfaces separately connecting one image process module, one wireless remote communication module and one load machine; there is also one angle sensor composed of three circuit single axis speed with output signals orderly through one high band filter and one low band wave as signal amplifier into main control single machine.

Description

technical field [0001] The invention relates to a small airborne pan-tilt tracking control device, in particular to an airborne small, multi-sensor and multi-serial port pan-tilt tracking control device. Background technique [0002] The camera carried by the micro-unmanned aerial vehicle can be used for ground area monitoring or moving target tracking, which requires that the camera's line of sight can be accurately controlled according to the needs of the system to obtain images of the monitored area or the tracked target. However, the aircraft's body vibration and body attitude It is difficult to achieve precise control, and it is not feasible to directly fix the camera on the body, which requires a two or three degrees of freedom gimbal to carry the camera, through the accurate control of the gimbal to achieve the camera line of sight within a certain range Adjustment, and stabilize the camera to ensure that the camera line of sight can obtain a stable image of the monit...
