Both LiDAR and photogrammetry create 3D point clouds, but they work in fundamentally different ways. Choosing the wrong technology wastes time and money. Understanding their strengths helps you make informed decisions for every project.
How They Differ
LiDAR (Active Sensor)
- Emits laser pulses and measures return time
- Works in any lighting condition
- Penetrates vegetation to reach ground
- Captures thin features (wires, poles)
- Direct distance measurement = inherent accuracy
Photogrammetry (Passive)
- Calculates 3D from overlapping photos
- Requires good lighting and texture
- Cannot see through dense vegetation
- Produces RGB-colored point clouds
- Lower equipment cost than LiDAR
When to Choose LiDAR
LiDAR excels when you need:
- Bare-earth terrain under forest canopy, where photogrammetry cannot see through trees
- Thin infrastructure like power lines and telecommunications towers
- Challenging conditions such as low light, overcast weather, or light rain
- Maximum accuracy when precise elevation data matters most
When to Choose Photogrammetry
Photogrammetry shines when you need color imagery and textured 3D models at lower cost
Visual Richness
Natural RGB colors and photorealistic textures for visualization and presentation.
Cost Effective
A camera costs far less than a LiDAR sensor, making it accessible for smaller budgets.
Open Terrain
For areas without dense vegetation, photogrammetry produces excellent results efficiently.
The Hybrid Approach
Many projects benefit from combining both technologies:
- LiDAR for accuracy and ground detection through vegetation
- Photogrammetry for color and visual context
LidarVisor supports colorizing LiDAR point clouds with imagery, giving you the precision of laser measurement with the visual richness of photography.
