1

LMMS samples road-side trees at ~50 km/h Goal: extract tree parameters at a processing speed of 50 km/h as well

2

Workflow 1. Retile and downsample 2. Classify tree points 3.& 4. Separate individual trees → approximated tree parameters 5. For each tree: upload original points → high quality tree parameters Red: full point density Green: voxels, of, say, 30 cm

3

Workflow: example

4

Results obtained at a processing speed of 10 km/h Test data: 7km Full data: 200 km

Goal: extract tree parameters at a processing speed of 50 km/h as well
