实景影像采集的错帧问题与解决措施

Stagger Frame in Real Image Capture and Its Solution

实景影像地图是近年来出现的一项新的数据产品，其应用越来越广泛。但在实景影像的采集作业中，由于软硬件设备的偶发故障会造成实景影像错帧，影响了数据的后期应用。本文结合作业实践，综合分析了错帧问题产生的原因，指出采集传感器间的信号延迟是造成错帧的主要原因。在此基础上，提出了一套完整的解决方案，经实践应用，证明该方案有效解决了错帧问题。

Real image map is a new geographic information product and has a wide application. However, the stagger frame caused by accidental software or hardware malfunction during real image capture has a terrible influence on follow - on application. Combined with practice, comprehensive analysis of the stagger frame problem is conducted and signal delay among collection sensors is considered to be the primary reason. On the basis of analysis, corresponding solutions are proposed and has proved to be effective after put into practice.
