摘　　要：为了得到多信息进行信息融合,光电经纬仪采用多传感器的方法,即在主光轴及辅助光轴上安装了传感器。主光轴传感器获得的测量数据,可按常规方法进行脱靶修正;辅助光轴与主光轴存在平行度,辅助光轴传感器获得的测量数据,处理时必须对结果进行平行度修正。采用坐标变换方法推导出多传感器跟踪误差修正公式,获得目标的方位角、高低角,经实际验证表明,该方法可有效提高处理精度。In order to get multi-source information to implement data fusion, Photo-electric theodolite installs sensors on the main visual axis and secondary visual axis. The main visual axis t data can correct off-target with conventional methods. Because the auxiliary visual axis has different parallelism from the main visual axis, its measurement data must be modified with the parallel correction while processing the results. The multi-sensor off-target correction formula can be worked out by the coordinate transformation method, and the target azimuth and elevation angle are obtained afterwards. Practice verification shows that this method can effectively improve the processing accuracy.
