Target detection method and device based on image sequence

The invention provides a target detection method and device based on an image sequence. The method comprises the following steps: acquiring a to-be-detected image sequence including an image at the current moment; obtaining a plurality of backbone feature maps with different sizes and a plurality of sequence feature maps with corresponding sizes of the image and the image sequence at the current moment respectively; performing channel aggregation based on the plurality of backbone feature maps and the sequence feature maps of the corresponding sizes to obtain a plurality of target feature maps of the corresponding sizes; and fusing the plurality of target feature maps to obtain a target detection result. According to the invention, the problem that the target detection performance of a target detection method in the prior art is limited under the interference of image motion blurring, object shielding and the like is solved. 本发明提供一种基于图像序列的目标检测方法及设备，该方法包括：获取包括当前时刻图像的待检测图像序列；分别获取当前时刻图像和图像序列的多个不同尺寸的骨干特征图和多个对应尺寸的
