What is Matterport
Matterport has focused on its virtual tour deliverable, however it can produce a point cloud and so it is an interesting potential cheap solution for those looking to dip their toe into 3D scanning or introduce point clouds on a project.
RED is the Matterport data, BLUE is the Leica P20
The vertical accuracy shows a deviation of ~5 inches over a mere ~17 feet. This deviation is consistent across the entire floor. The reason for the large error is due to the dramatic falloff in accuracy with distance. The Matterport sensors cannot shoot directly up, and in order to reach the ceiling they measure at an angle and at the furthest extents of their range. Matterport suggests scanning closer together, or lifting the scanner on a high tripod to provide more accurate data on high ceilings.
The overall levelness of the data is excellent. No real difference between the Matterport and the p20. However, at the ends of the floor there is a "potato chip" warping effect. This is probably the same effect occurring on the ceiling: data far away from the scanner is less accurate (there were no scans directly near these areas).
One thing to note, we needed 2.5 times as many scans for the Matterport compared to the P20. This is due to the short range of the Matterport scanner.
