Benefits of technology

[0044]本发明实施例提供了一种基于序列图像的地理定位方法、装置及计算设备，该方法利用子场景图像序列中场景相同的特点对待处理视频图像进行切分，以通过子场景图像序列中包括的若干单帧图像进行融合增强处理，生成包括完整空间要素的当前场景的子场景增强图像，然后通过预设地理空间知识库，确定子场景增强图像对应的候选地理位置，最后基于对候选地理位置的融合排序，确定待处理视频图像的目标地理位置。如此，该方法解决了序列图像中单帧图像特征显著性弱、无法有效利用序列图像的时空相关性、定位地点模糊性高的问题，通过聚合贯穿序列图像中可用的定位特征，在序列图像时空相互约束关系下进行联合地理定位，提升了地理位置的定位精度。

Abstract

The application provides a geographical positioning method and device based on a sequence image and a computing device, and the method comprises the following steps: splitting a to-be-processed video image to obtain a sub-scene image sequence; wherein the sub-scene image sequence comprises a plurality of single-frame images with the same scene; performing fusion enhancement processing on all single-frame images in the sub-scene image sequence to obtain a sub-scene enhanced image; determining a candidate geographical position corresponding to the sub-scene enhanced image according to a preset geographical space knowledge base; and performing fusion sorting on the candidate geographical position to obtain a target geographical position of the to-be-processed video image. The geographical positioning method based on the sequence image provided in the scheme effectively utilizes the sequence image to improve the geographical positioning precision.
