Abstract

The invention relates to the technical field of unmanned aerial vehicle positioning, discloses an unmanned aerial vehicle positioning method and device fusing visual data and laser data, electronic equipment, a computer readable storage medium and a computer program product, and is used for solving the problems that an unmanned aerial vehicle positioning method in the prior art is greatly influenced by scene environment feature changes, and the positioning accuracy is high. And universality and robustness are not good. The method comprises the following steps: acquiring visual data and laser data, and generating a visual point cloud and a laser point cloud; respectively extracting feature information of the visual point cloud and the laser point cloud, and matching and aligning the visual point cloud and the laser point cloud according to the feature information; evaluating position measurement errors of the visual point cloud and the laser point cloud in real time, and dynamically calculating weight parameters; and carrying out weighted fusion positioning in real time based on the visual image and the laser image in combination with the weight parameter to obtain unmanned aerial vehicle positioning information. According to the method, the unmanned aerial vehicle can adaptively fuse visual and laser data according to an actual scene for accurate positioning.
