Rotorcraft UAV laser charging target center location algorithm

Using laser features of high brightness and good directivity, can undertake directional transmission of energy, laser charging technology transforms the energy supply way with its own carrying to charge at any time. The key to laser alignment is to identify the target of the charging panel and locate the center. Through the control of the servo module, the battery charging plate can be adjusted to the center of the field of view to complete laser alignment charging. Object recognition and center location algorithm are mainly divided into three steps: image preprocessing, rectangle panel identification and center positioning. Through this, the center positioning is realized, and the center positioning of the panel charged by laser is carried out for rotorcraft with different distances and angles, so as to achieve a better effect.
