A Small Object Detection Method for Drone-Captured Images Based on Improved YOLOv7

Dewei Zhao,
Faming Shao,
Qiang Liu
et al.

Abstract: Due to the broad usage and widespread popularity of drones, the demand for a more accurate object detection algorithm for images captured by drone platforms has become increasingly urgent. This article addresses this issue by first analyzing the unique characteristics of datasets related to drones. We then select the widely used YOLOv7 algorithm as the foundation and conduct a comprehensive analysis of its limitations, proposing a targeted solution. In order to enhance the network’s ability to extract features… Show more

“…Yu et al [26] focused on the issues of occlusion and overlap of objects in RS images, emphasizing the strategy of large-scale proposal bounding boxes, and constructed a novel spatial adaptive detector (RSADet). Zhao et al [27] introduced non-striding convolution and an attention mechanism into YOLOv7 to improve the feature extraction capability for small targets, and optimized the fusion process of deep information for small targets using the Lion optimizer. In article [28], a joint motion mechanism based on a three-degree-of-freedom (DOF) framework was designed for drones in complex motion patterns to achieve real-time active tracking of targets.…”
