How to achieve 20 fps with miraco plus

Testing out miraco plus, and first impression is, identical as miraco pro… didn’t use the metrology kit yet… and 16 fps is highest I got…

Does the 20fps work with PC only and can I connect to ipad/iphone?
What is the limitation to why it cannot achieve more FPS - is it the cpu?
And if the fps is higher will this result in less loss in tracking?

What is the purpose of the HDMI cable to USB connection - there is no output to hdmi happening on my end?

Is the mini 2 better in tracking and accuracy? Does it capture texture: does someone know a good workflow to combine classical photogrammetry wia dslr and these scanners - for better texture quality. Basically what I guess I need is a way to rotate and scale the photogrametried object same to the miraco’s - is there a tool for that …

thanks,

You can’t connect Android tablet to a iPhone , why ?
There is not even a benefit of doing so.
You can connect to MAC or PC to have a u benefit .

Your last bus is need to have proper smooth of tracking points ( features) to be able to keep tracking , more speed of frames will not fix that , you are using. 3D Structured light scanner that relays on features to keep tracking.

It is USB C to HDMI to connect your Miraco to portable touch screen , TV , projector

MINI 2 accuracy is better but it needs more tracking points on your objects since it is created to scan very small objects only , how higher the accuracy how small the tracking point distance is required .

MINI series can scan textures but it is less good to archive because MINI series need very low environment lighting since it uses blue light for scanning , any colors other than blue can absorb the blue light making it difficult to scan in full color .
Blue light scanners like MINI series works best when used with 3D spray .

It is not the same as MIRACO /pro , it also have zoom options in near mode to scan objects with higher accuracy and PMK .

The highest frame speed is in High speed mode .
4 frames more or less makes zero difference.

Speed can wary regarding the area of being scanned and the intensity of the point cloud .

OK thanks a lot for the answers… appreciate it… still haven’t gotten to all the features of miraco, so just randomly testing what’s obvious to me

I’m used to photogrammetry, and I can get very good / predictable results - but of course it takes a lot of time to make an actual thing … I’ve even built my light box out of three 60x60 led panels meant for ceiling - at 40 watts each - so I get uniform lighting - and built arduino / stepper motor turntable with a relay to trigger the camera to take consistent photos…

Anyway, the textures on miraco look like web cam quality photos to me - 4k 8k… does not look like it is 4k - I guess it can be improved if I have a good constant lighting - but I guess I can’t expect much from phone camera type lenses / camera sensors… vs a 5k$ dslr

So what do you think the metroX might be less work / faster performing - what’s the blue light limitation?

So far I would like to use it to scan object to use in scenes such as rocks and nature… and I can get good scans of rocks, textures are broken - as soon as I turn it around the lighting condition changes … I wanted to maybe use the photogrammetry to improve textures…

4-8 K is the resolution for the Single shot mode only , when you take a picture on a distance propably only 2K will be used from the 8K anyway .
It is a RAW shot so not edited or process with filters as you have on a phone with the same sensor that actually cost $40 .
The sensor needs a very good lighting conditions .
MIRACO is not a DSLR and never intended to be other way it would cost 16K .

Single shot mode at 8K are very good and pleasant results .
But you can’t compare it to DSLR , it is Android Tablet after all .

With your light settings you may get very good results , remember the center for camera is on the left , not in the middle of Miraco when setting light source .

I can’t talk about Metro X , you will need to wait until the KS page is ready with all specifications .

But It is not propably what you need , it is strictly for reverse engineering stuff and reconstruction and not just for scanning random stuff , so you probably will have nothing from it since it is far away from what you doing I assume .

Well light changes with photogrammetry too if you moving around .
I would suggest you build your own mobile lighting on a bracket so it follows the scanner and deliver the proper lighting levels .

Make sure you use calibration board for calibrate white balance and exposure but since you doing photogrammetry you must know that already .
