Lidarvisor - Steep Terrain Classification

Deep learning models handle steep terrain without parameter adjustment

Why Ground Classification Is So Frustrating

Accurate ground classification determines the quality of every downstream product. If ground points include vegetation or building edges, your DTM will have errors. If true ground points are filtered as noise, you lose critical terrain detail.

Traditional ground classification algorithms require constant parameter tuning, and what works for one terrain type fails completely for another.

Traditional Classification Methods

Morphological Filtering

Uses minimum elevation within moving windows to find ground. Requires separate settings for each terrain type.

change_history

Progressive TIN Densification

Builds a triangulated surface from lowest points and adds points within angle/distance thresholds. Sensitive to initial seed points.

Slope-Based Methods

Iteratively classifies points based on slope relative to neighbors. Struggles with steep terrain and cliff edges.

Each approach requires parameter tuning: maximum slope angles, window sizes, height thresholds, iteration counts. Parameters optimized for flat coastal terrain fail in mountains. Urban settings need different values than forests.

AI-POWERED SOLUTION

How AI Ground Classification Eliminates the Guesswork

Deep learning models learn what ground looks like from examples

Instead of following explicit rules, neural networks learn to recognize ground points from examples. Train on millions of labeled points across diverse environments, and the model learns what ground looks like in different contexts.

KPConv and PointNet++ process 3D point coordinates directly

Each point analyzed within its local neighborhood

Considers elevation, geometry, density, and context simultaneously

AI classification separates ground from vegetation with consistent accuracy

Training on Global Datasets

The key to robust AI ground classification is diverse training data. When the model has seen enough examples of each scenario, it learns to recognize ground regardless of the specific environment.
