Pix4Dmapper Now with Fully-Automated DTM Extraction

­

Precisely distinguishing bare earth from digital surface models (DSMs) has always been sought-after. However, it remains difficult to precisely separate objects from terrain, due to the large variety of vegetation and man-made structures above ground

Pix4D is proud to announce our implementation of some of the most successful academic research for DTM extraction into Pix4Dmapper, starting from 3.1.13 Preview. Using DSMs generated from high-resolution images, Pix4Dmapper algorithms can now detect bare earth, as well as compute and remove above-ground objects precisely without pulling the terrain height up for interpolation. This new approach gives the accurate terrain model elevation, instead of just visually removing objects.

This fully-automated algorithm works perfectly on surface models, whether it contains small and scattered houses or large, dense trees. To experience the amazing new DTM extraction, download Pix4Dmapper trial now.

* In Pix4Dmapper, simply check the option “Raster DTM”, and you will find the terrain model saved in the extras folder inside step 3. 
The contour lines (if needed) will also be generated based on the DTM instead of DSM.
