Using a Miraco Pro, I noticed today that standard fusion is producing significantly fewer points than advanced mode. Given advanced produces a clean “best of” sort of point cloud, that seems counterintuitive.
Upon further investigation, it seems that standard mode can produce a maximum of 50,000 points per frame whereas advanced seems to have no such limitation.
It’s an easy enough thing to test in single shot mode. A single frame in far mode at .28mm point distance produced 604,814 points in advanced and 50,000 in standard. At the recommended point distance of .67 for this particular test shot, advanced produced 95,445 points and standard 37,218.
In continuous mode it’s obviously harder to pinpoint but point totals for standard being around 25% of the advanced total seems average in limited testing.
Unfortunately I discovered this after laboriously re-assembling a botched single-shot mode capture that refused to align without being manually broken into individual frames and merged back together. After 16 frames I only had ~72K points spanning an 8 foot wide section of vehicle.
The Standard fusing mode includes all data including overlapped points and lots of noises that need to be heavily cleaned after , this Algorithms are for those that looking for raw data , after cleaning the raw data manually in any other program that allows point cloud editing you literally ends with the same amount of points that Advanced fusing mode produces .
Advanced fusing mode do not reduce the accuracy , this advanced fusing mode clean automatic most junk data that was captured and are really not nesesery to build a mesh from it .
Adding more points will not create better accuracy or resolution , the accuracy is already determined by the hardware and can be reduced via processing but never increased .
Safe yourself work and use advanced mode , making sure you use the proper resolution fusing settings according your object details . Setting fusing all way up will not increase any details on objects that originally do not have that details scale .
Merging separate single shot frames is kinda pointless , you need at least 3 frames from 3 different angles to have full 3D shot .
On top the merging function at this moment is kinda wonky , but the dev team is working on the solution as we speak .
Not really , the dev team is on it , hopefully vertex color returns soon to merging function so we can use own color markers for more precision with merging scans that do not have enough features .
I am preparing tomorrow the merging projects for the Dev team for full evaluations with random scanners to ensure there is not precision issues in the algorithms .
Cleaning and cutting bad edges helped a lot and that is must have workflow , but lately it still missing the points despite the scans was clean .
I am on it , it is being too long already and this issue getting everyone on the nerves .
