The invention relates to the technical field of target positioning, and particularly discloses a vision and satellite navigation combined target positioning method, which comprises the following steps: acquiring satellite images of an application area under different precisions, and extracting image features of the satellite images under different precisions in a target area as target features; performing statistics on the target features and the corresponding precision to obtain a target feature table; in the application stage, acquiring a satellite image based on a preset acquisition frequency, positioning a target in the satellite image based on a target feature table, determining an operation path of the unmanned aerial vehicle based on the target position, sending the operation path to the unmanned aerial vehicle, and acquiring supplementary video data of the target by the unmanned aerial vehicle; according to the method, the target position is preliminarily acquired through the satellite, then the unmanned aerial vehicle performs data auxiliary acquisition, the satellite precision requirement is not high, the cost is low, the unmanned aerial vehicle only needs to be controlled on the ground, high-altitude operation is not involved, and a target positioning scheme which is low in cost and extremely high in safety is provided.
本发明涉及目标定位技术领域,具体公开了一种视觉与卫星导航联合的目标定位方法,所述方法包括获取应用区域在不同精度下的卫星图像,提取不同精度下的卫星图像在目标区域中的图像特征,作为目标特征;统计目标特征及其对应的精度,得到目标特征表;在应用阶段,基于预设的采集频率获取卫星图像,基于目标特征表在卫星图像中定位目标,基于所述目标位置确定无人机的运行路径,将运行路径向无人机发送,由无人机获取目标的补充视频数据;本发明通过卫星先初步获取目标位置,再由无人机进行数据辅助采集,卫星精度要求不高,成本较低,无人机只需要在地面上进行控制即可,不涉及高空作业,提供了一种成本较低且安全性极高的目标定位方案。
