Abstract

In order to solve the problems that in spaceborne optical remote sensing image ship target detection, the ship target scale change is large, and the calculated amount of a spaceborne platform is seriously limited, a lightweight multi-scale feature extraction network module is introduced, and the ship target detection efficiency of a deep learning network can be effectively improved. The inventiondiscloses a satellite-borne optical remote sensing image ship target detection method based on a lightweight receptive field pyramid. A method for constructing a lightweight receptive field pyramid byintroducing hole convolution is adopted, a multi-scale feature fusion detection module is constructed according to multi-scale features extracted from the receptive field pyramid, and the adaptability to optical remote sensing image ship target features is improved under the condition that the network scale is limited.

Description

technical field [0001] The invention belongs to the field of remote sensing image processing, in particular to a target detection method for optical remote sensing images. Background technique [0002] Ship detection based on optical remote sensing images has always been a research hotspot in the field of remote sensing target recognition. Ships are very important strategic targets in both civilian and military fields. With the rise of deep learning, early manual features have gradually been unable to meet the increasingly complex optical remote sensing visual recognition tasks, and deep learning has shown strong feature representation capabilities in the wide application of computer vision. How to design a deep learning detection network suitable for the characteristics of ship targets in optical remote sensing images has become a major challenge for ship target detection in remote sensing images. [0003] In order to improve the performance of all aspects of the deep lear...
