Accuracy of Matterport pro3 Scan for Construction17913

EMILIANO private msg quote post Address this user
Good evening everyone,

I would like to discuss with you to find out if anyone has carried out any accuracy checks in the measurements of the MATTERPORT PRO3. I carried out a test on my work that I had verified the measurements with a theodolide. If you have your own experiences let's compare.

Also, how would you go about scanning to maximize the accuracy of the scans through a medium to large project - in PRO3. ?

Hey @Aeronautica3D,
to minimize measurement errors, based on my experiences with the MATTERPORT PRO2 (although I recommend always taking random verification measurements), to carry out the measurements from point A to point B (to simplify… if I have to scan an entire building effects the scans like a photocopier, in one direction only) while I do not recommend the "circular" scan with measurements from point A always returning to point A, the measurement errors increase.

So for a 100 ft corridor, 10 ft wide, would i get better results if I take scans every 10 ft? Than say every 20 ft?

The more frequently you are scanning the more accuracy you should get but corridors are tricky. If they are empty and look similar over their whole length Matterport can put one scan in a wrong part of it and that can make huge errors.

ah okay....
in general, the more scans and more detailed environment, I should get better accuracy?

in both theory and practise yes. Just imagine you did a next scan at a corner with a hall turning 90 degrees and Matterport due to the lack of data on both sides(before the corner and after it) did not identify correctly a corner angle. If you leave it like this you got totally wrong angle for the corner turn. However if you keep scanning near the corner next scans will be correcting the corner angle with every next scan around it.
