The TrueView GO is designed primarily as a handheld SLAM-based LiDAR system for walking applications. However, it can be mounted on a vehicle for corridor scanning if proper speed and mounting practices are followed. This article provides guidance on optimal travel speed, setup tips, and quality assurance steps for car-mounted TrueView GO workflows.
Recommended Travel Speed
- Optimal Range: 5–10 mph (8–16 km/h)
Best balance of SLAM stability and point density. - Upper Bound: Up to ~15 mph (24 km/h)
Acceptable only in feature-rich environments and when GNSS RTK corrections are active.
Why this range? SLAM requires overlapping frames and consistent environmental features to maintain trajectory accuracy. Higher speeds reduce overlap and can cause drift or sparse point clouds, especially on straight, feature-poor roads.
Factors Affecting Speed
- Environment:
- Urban corridors with poles, signs, and façades allow slightly higher speeds.
- Open highways or feature-poor areas require slower speeds.
- Mount Stability:
- Rigid, vibration-damped mounting is critical for data quality.
- GNSS Availability:
- RTK corrections improve global accuracy and allow safe operation near the upper speed limit.
Setup & Field Tips
- Mounting
- Use a TrueView Suction Mount for a rigid mount with minimal vibration.
- Keep the sensor level and unobstructed.
- GNSS & SLAM
- Enable RTK if available.
- Brief revisits to distinctive features help reinforce SLAM.
- Route Planning
- Avoid long, feature-poor segments or slow down significantly.
- Safety
- Follow local traffic laws and prioritize safe driving.
Quick QA/QC Workflow (LP360 LAND)
After a short test run (100–200 m):
- Check trajectory confidence and SLAM residuals.
- Review point density maps for gaps or streaking.
- Validate alignment to fixed features (signs, poles).
If results are good, gradually increase speed in small increments and re-check.
Model-Specific Notes
- TrueView GO 116S (16-channel, 320 kHz): Favor lower speeds (5–10 mph).
- TrueView GO 132S (32-channel, 640 kHz): Can tolerate slightly higher speeds (up to ~15 mph in good conditions).
When to Consider Alternatives
If your project requires sustained higher speeds or long, feature-poor corridors, consider a vehicle-optimized dual mapping mobile mapping and drone lidar system with dedicated IMU and trajectory processing.
