Abstract

The invention discloses a device and a method for measuring a to-ground height of an unmanned aerial vehicle in the field of electronic information, and belongs to the technical field of electronic information. The device comprises a central processing unit, wherein the central processing unit is electrically connected with a distance collecting system and an unmanned aerial vehicle state collecting system in an input manner respectively; the central processing unit is electrically connected with a wireless transmission system, a control system and a display system in an output manner respectively. According to the device and the method, a locating image frame is collected through an optical-flow camera in the distance collecting system; an ultrasonic generator measures the to-ground distance; a distance value and the pixel of the image frame are comprehensively compared and analyzed; the locating coordinate of an aircraft is obtained; the accurate measurement of the to-ground height is obtained; the electric quantity, the failure and the signal intensity of the unmanned aerial vehicle are detected through the unmanned aerial vehicle state collecting system; a control background masters the flight state of the unmanned aerial vehicle in real time; the control information of a controller is transmitted to the unmanned aerial vehicle through the wireless transmission system so as to control the unmanned aerial vehicle.

Description

technical field [0001] The invention relates to the technical field of electronic information, in particular to a device and method for measuring the height of an unmanned aerial vehicle to the ground in the field of electronic information. Background technique [0002] UAV is an unmanned aircraft controlled by radio remote control equipment or onboard computer program control system. UAV is simple in structure and low in use cost. Tasks play an important role in emergencies and early warning. The height measurement of the ground when the UAV is flying is often an important data to ensure the safety of the flight. The computing power requirements of the processor are naturally high, so the cost of the equipment has increased significantly. Moreover, the camera is usually mainly used for flight aerial photography. Technically, the optical flow camera (the principle is the same as the photoelectric sensor for mouse displacement detection) is used to replace the traditional ca...

[0002] UAV is an unmanned aircraft controlled by radio remote control equipment or onboard computer program control system. UAV is simple in structure and low in use cost. Tasks play an important role in emergencies and early warning. The height measurement of the ground when the UAV is flying is often an important data to ensure the safety of the flight. The computing power requirements of the processor are naturally high, so the cost of the equipment is greatly increased. Moreover, the camera is usually mainly used for flight aerial photography. Technically, an optical flow camera (the principle is the same as the photoelectric sensor for mouse displacement detection) is used to replace the traditional camera unit, but since the optical flow camera is a telephoto camera, the captured image area is relatively small, and the amount of information processed is relatively small , based on this, the present invention designs a device and method for measuring the height of an unmanned aerial vehicle to the ground in the field of electronic information, to solve the above-mentioned problems
