Recommendations
Planning a Route
- Identify the suitable start/ finish location with relation to the project. The capture should finish within 1m from the start location, facing the same features.
- Make sure there are plenty of features along each captured road (i.e. street signs, parked cars, trees, buildings. etc)
- Plan the drive that enables loop closure in smaller streets. Straight linear road capture (> 250m) should be avoided)
During Capture
- Make sure the ZEB Horizon system is firmly installed on the car mount and on the car’s roof.
- Start the system while the car is parked with the engine off.
- As soon as the scanner starts rotating, start the drive.
- Drive slowly – 30 mph maximum. For higher point density, consider driving slower (15 – 20 mph). Drive slow in narrow streets with tree cover.
- Maximum capture time – 20 minutes.
- Finish the capture on the same starting point. If possible, approach the end parking location from a different direction than you started.
- Wait until the data is compressed before switching the system off.
Data Processing
- Processing parameters might need to be adjusted on the project basis. For large area captures, it might be necessary to increase Windows size and Convergence threshold (both Local and Global SLAM). Both parameters can be increased to 2 or 3 to start with
- If the finish location was not within 1 meter of the starting position, Start/ Finish closed loop will need to be unticked
- If parts of the car are caught up in the capture, increased bounding box size will eliminate those close points
