Mobile system projects
This chapter outlines typical processing workflows for images from mobile systems. Usually, mobile systems include several cameras, such as down-looking and side-looking cameras. The first part in the processing workflow is to check the calibration of the camera system and possibly improve the camera parameter values using tie points. Images from down-looking cameras can then be used to create orthophotos of the ground (e.g. of the road surface). The images from side-looking cameras may be utilized to assign color values to laser points.
Furthermore, images of the road surface allow the collection of specific tie point types that can be utilized by TerraMatch for the derivation of corrections values. This supports the correction of the trajectory drift for high-accuracy work.
