Abstract:

In order to solve the problem of three-dimensional measurement of objects that cannot be contacted closely in special scenes, the UAV(Unmanned Aerial Vehicle) hoisting measurement system is designed and implemented based on UAV and raspberry. The cascaded raspberry is used to realize image transmission and data transmission link. The laser sensor, GNSS(Global Navigation Satellite System)sensor and monitoring lens sensor are utilized to realize information acquisition and combined with electric telescopic rod to realize the vertical adjustment of measuring device. The binocular camera is used to collect information to realize scene three- dimensional modeling and object three-dimensional accurate measurement. The UAV hoisting measurement system is composed of five parts: power system part, image transmission and data transmission integrated link part, positioning and height acquisition part, electric telescopic rod part and object three-dimensional measurement part. The test results show that the UAV hoisting measurement system can quickly, effectively and automatically construct the three-dimensional measurement scene and complete the actual three-dimensional dimension measurement of the target object. The accuracy error is up to 1% , and the expected effect is achieved.

Key words: unmanned aerial vehicle ( UAV), dimensional measurement, 3D model, raspberry, binocular camera
