Embodiment Construction
[0050] Inspired by the behavior of homing pigeons using landmark information for navigation, the invention proposes a new autonomous navigation method for unmanned aerial vehicles. Combined with convolutional neural network and visual positioning and mapping methods, the positioning is optimized by using the results of target recognition, and the environment perception and autonomous navigation functions of the UAV are realized.
[0051] The effectiveness of the system and method proposed by the present invention will be verified below through a specific simulation test example. Specific steps are as follows:
[0052] Step 1: Initialize the environment field and train the neural network
[0053] Initialize the experimental environment, collect images of landmark samples with distinctive features and common moving objects in the environment to create a training data set. Input the YOLOv3 network to train the target, and get a neural network model suitable for the current envi...
