Detection of Ground in Point-clouds Generated from Stereo-pair Images

چکیده
This paper proposes a new approach for constructing digital terrain models (DTM) from the point-clouds generated from airborne stereo-pair images. The method uses data decomposition based on the differential attribute profiles and Θ-mapping for the extraction of the most-contrasted connected-components. Their filtering is achieved based on multicriterion threshold function. The method is evaluated by comparing the output DTM with the reference Light Detection and Ranging data (LiDAR).
