- Abstract:
-
Aiming at the problem that the quadrilateral aircraft has poor recognition effect and low precision, we studied the method of quadcopter obstacle recognition using a multisensor based on an ultrasonic sensor, infrared ranging sensor, and lidar sensor. The original data evidence weight of the sensor was optimized using the fruit-fly optimization algorithm (FOA) to obtain the optimal weight. According to the optimal weight of each sensor, an improved D-S evidence theory algorithm was used to fuse the data of multiple sensors to improve the obstacle recognition accuracy of the quadcopter. By comparing the single sensor and other data fusion algorithms, the research results show that under the same condition, the proposed method has a higher recognition accuracy for obstacles and faster response to obstacles.
