The invention provides an earth observation space cloud service vehicle target three-dimensional tracking method, and belongs to the field of remote sensing image processing. According to the invention, the epipolar line image is generated by using the RPC parameter and dense matching is carried out, the road in the satellite video image is extracted by using the migrated neural network to obtain the road mask, the vehicle target to be selected is purified by combining the extracted road mask to obtain the vehicle target on the road, and the vehicle target on the road is obtained according to the dense matching result. And obtaining three-dimensional coordinates of the vehicle target. According to the invention, tracking of the three-dimensional vehicle target can be carried out only with little manual intervention, in addition, large-scale satellite video images are used as data sources, and large-scale three-dimensional tracking of the vehicle target can be realized at the same time. 本发明提出了一种对地观测空间云服务车辆目标三维
