ensure that the scanner is relatively stable, and the door is open as much as possible. If the door is closed, when
approaching the door, you need to turn the scanner back to the door and open the door with the other hand.
During the process of passing through the door, you should fully consider the scanning field of vision and scan
the scenes outside the door as much as possible in the room. When closing the door, try to avoid the scanner
scanning the moving door as much as possible, to prevent data calculation errors.
Matters needing attention when turning corners
When the hand-held scanner passes through the corner, it is recommended to avoid too fast corners, and the way
of the corner should be considered in route planning. Get as many point cloud data at the same position before
and after the corner as possible to improve the accuracy of data calculation.
Matters needing attention in large-scale data acquisition
When the scanner is used to collect large-scale data, the whole survey area should be divided to facilitate the data
calculation efficiency, improve the calculation accuracy and facilitate the survey area management. Divide the
larger survey area into several small survey areas. It is suggested that the planned data collection time of each
survey area should be 25-30 minutes, and the overlapping range of survey areas should be at least 30%.
Suggestions for scanning long corridors (Tunnels)
Generally, the data obtained in areas with rich features and textures will have good calculation results. To ensure
the calculation accuracy, it is necessary to manually set a feature point with a diameter of about 1 meter every 10
