Best Practices and Methodologies to Mobile Mapping
- Use shortest route needed to adequately map an area
- Close the loop. Loop closure is the act of correctly asserting that the LiBackpack has returned to a previously visited location. A closed-loop route will help to prevent accumulative drift error and distortion of the final data.
- Make slow, wide turns around corners
- When going up and down a staircase, the scanner should be kept parallel to the staircase
- If an about-turn is necessary, try to be as slow as possible and make sure the rotation speed is less than 30 degrees per second
- Do not move features in the mapping area once data collection has begun
- Do not double-back along the same route of travel while capturing data with LiBackpack
- Begin from a stationary position in an environment with ample features
- Begin data collection after point cloud appears on the user's device
- When mapping open areas, do not start scanning in a corner or against a wall
- Ensure only one device is connected to the LiBackpack WiFi connection at any given time.
- It is recommended the battery be above a 30% charge during data acquisition
- The distance between the LiBackpack and the display device should not exceed 5 meters.
