Abstract

The invention provides range finding equipment and an unmanned plane, and relates to the range finding control technical field; the range finding equipment comprises a controller, and a signal generator and a signal detector connected with the controller; the signal generator is triggered by the controller so as to emit range finding signals according to preset time intervals and frequency parameters; the signal detector is used for detecting a reflection signal reflected by a detected object responding to the range finding signal; the controller is used for recording the emission time of therange finding signal and the reception time of the reflection signal, and calculating a distance value of the detected object according to the emission time, the reception time, and a pre-stored rangefinding signal propagation speed. The range finding equipment and the unmanned plane can use the controller to realize the whole range finding calculation process, thus reducing requirements on the environment factors; the equipment can be hardly affected by the environment factor, thus improving the measuring accuracy in certain level.

Description

technical field [0001] The invention relates to the technical field of ranging control, in particular to a ranging device and an unmanned aerial vehicle. Background technique [0002] UAV is an unmanned aircraft operated by radio remote control equipment and self-contained program control device. Because of its flexible action and convenient operation, it is used in various fields, such as aerial photography, agriculture and monitoring. [0003] Usually, when UAVs perform operations, they have certain requirements for their flying height and the distance of the monitoring object. The devices used in the traditional ranging function have high requirements for environmental factors, resulting in large measurement errors, making unmanned The stability of drone operations is reduced, thereby reducing the efficiency of drone use. Contents of the invention [0004] In view of this, the object of the present invention is to provide a distance measuring device and a UAV, so as t...
