Embodiment Construction
[0017] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0018] figure 1 It is a flowchart of the method of the present invention, the method may further comprise the steps:
[0019] S1: Preprocess the spatial position of the UAV airborne platform and adjust it to a detectable height range. The specific steps of UAV spatial position adjustment are as follows:
[0020] S11: Use GPS positioning technology to obtain the height H of the drone to the ground;
[0021] S12: Judging whether the current spatial height of the drone satisfies formula H min ≤H≤H max , if it is, the vehicle target detection is performed, otherwise, the spatial position of the UAV is adjusted to meet the above spatial constraints.
[0022] S2: Collect positive and negative samples of infrared images for vehicle target detection offline, preprocess the samples respectively, use convolutional neural network (CNN) to perform...
