Enhancement of Lidar Planimetric Accuracy using Orthoimages

Krzysztof Bakuła , Wojciech Dominik , Wojciech Ostrowski

Abstract

In this study the planimetric accuracy of lidar data was verified by registration of laser reflection images, point cloud modelling results and true orthophoto. The presented research is the basis for improving the accuracy of the lidar processing products, which is particularly important in issues related to surveying measurements. In the experiment, the true orthophoto generated by dense matching of aerial images was used to check for the planimetric accuracy of lidar data in two proposed approaches. The first (intensity-based) analysis is carried out by comparing coordinates of manually selected, salient points in the true orthoimages and rasters of the lidar reflection intensity. The second (feature-based) method to verify planimetric accuracy is based on matching roof ridges extracted from lidar data and true orthoimages. Both analyses were carried out for 3 fragments of lidar strips. A detected systematic planimetric error in the centimetre level range enabled the implementation of appropriate local correction for the analyzed data. The presented solutions provide an opportunity to improve the planimetric accuracy of lidar data that allow its efficient usage.
