光学遥感图像受背景复杂度和语义信息量大等影响,在检测精度和效率上仍然存在一定的不足。本文提出了以Resnet50为基础特征提取的SSD300网络模型,加入注意力机制CBAM模块和特征融合FPN模块,采用Soft-NMS策略选取最终预测框,对遥感图像飞机目标进行更加有效地检测。最后,在2 150张飞机遥感图像数据集上进行训练,当IoU为0.5和0.75时平均精度MAP达到92.54%和63.44%,较改进前的算法模型提升了5.04%和11.38%,检测速度达到24.1 FPS。实验结果表明,该方法可以有效提高物体的检测能力,以及快速、准确地检测机场区域内的飞机物体,有效降低了飞机物体的漏检率,提高了检测精度和速度。
Optical remote sensing images are affected by the complexity of the background and the large amount of semantic information
and there are still certain deficiencies in detection accuracy and efficiency. This paper proposes an SSD300 network model based on Resnet50 for feature extraction
adding the attention mechanism CBAM module and feature fusion FPN module
and adopting the Soft-NMS strategy to select the final prediction frame to detect aircraft targets in remote sensing images more effectively. Finally
training on 2 150 aircraft remote sensing image data sets
when the IoU is 0.5 and 0.75
the average accuracy MAP reaches 92.54% and 63.44%
which are 5.04% and 11.38% higher than the previous algorithm model
and the detection speed reaches 13.4 FPS. Experimental results show that this method can effectively improve the detection ability of objects and quickly and accurately detect aircraft objects in the airport area
effectively reducing the missed detection rate of aircraft objects and improving detection accuracy and speed.
