So earlier than we get on with the testing, let’s see what’s within the field, and the way it all works.
MIRACO Plus & Photogrammetric Metrology Package Overview
Whereas the unique MIRACO 3D scanners have been designed for scanning gadgets of varied sizes, the brand new MIRACO Plus with the Photogrammetric Metrology Package not solely helps common detailed scanning but additionally adapts seamlessly to advanced measurement eventualities.
The unique MIRACO scanners work by structured gentle expertise to map the geometry of an object. The scanner tasks a collection of sunshine patterns onto the item, and as these patterns deform over the floor, a stereo digital camera pair captures the ensuing distortions.
Photogrammetry works a bit of in another way, and depends upon 2D pictures taken from a number of angles to reconstruct a 3D mannequin.
The method calculates depth info by evaluating widespread factors throughout the photographs after which producing a 3D mesh primarily based on the geometry inferred from these factors. On this case, the widespread options are the coded targets and scale bars contained in the PMK.
You’ll be able to see the calibrated carbon fiber scale bars, and sticky / magnetic coded targets within the picture under. These have to be positioned liberally on/across the object being scanned.
Setting Up
Opening the principle field, we are able to see all of the equipment included with the MIRACO Plus and Photogrammetric Metrology Package. These embody energy provide, USB cable, markers, and a flowery carry case. You’ll be able to see all of them within the image under.
We obtained the instruction guide in PDF from Revoipoint instantly, and the directions are pretty straightforward to observe.
Opening the settings on the MIRACO Plus will present the scan modes, Level Cloud (3D scan), Photogrammetry, and World Marker. Level Cloud mode is the common scanning mode, discovered on the opposite MIRACO scanners. The opposite two modes are new to the MIRACO Plus.
Photogrammetry mode requires the size bars for metrology-grade duties, and World Marker mode combines steady scanning of the markers with level cloud for fast and correct scanning of huge objects.
Photogrammetry Mode
First, I needed to check the photogrammetry mode. To do that, it’s best to place not less than two scale bars towards or across the object’s floor, guaranteeing that they don’t seem to be parallel however positioned at an angle to at least one one other. The PMK’s coded targets should even be paired up with the MIRACO Plus 3D scanner, which might be carried out by way of the scanner interface. After this step is full, then the scanning can start.
Revopoint says this PMK is nice for scanning gadgets as massive as vehicles and plane elements. Sadly, I should not have both of these useful in the meanwhile, so I caught a bunch of the registration stickers throughout my desk at first (proven within the image above). It has a reasonably fascinating geometry and number of floor finishes.
After taking the required minimal 30 photographs from numerous angles, I processed the information on the hand-held unit and produced my first marker map. The onscreen directions are straightforward to observe, and the MIRACO Plus tells you while you make an error and have to retake a photograph. These errors are usually distance associated, or are attributable to not sufficient markers being within the scene.
For the following level cloud stage, the display and PC have been reflective, so I used to be unable to generate a full level cloud. I managed to supply some extent cloud and 3D mannequin of the encompassing areas although. Due to this fact, earlier than scanning clear, darkish or extremely reflective objects, utilizing scanning spray can give you a greater scanning expertise
That is going to take a bit of bit extra observe and plenty of spray to get proper. Just a few extra markers is perhaps useful too.
Onto the following mode, which might show a bit of easier to become familiar with.
World Marker Mode
The second new mode obtainable on the MIRACO Plus is the World Marker mode.
Whereas photogrammetry mode requires a number of particular person photographs and the size bars, World Marker mode makes use of a steady scan to create the worldwide marker factors.
Operating out of huge issues with first rate surfaces that I might scan, I lined a radiator in coded targets, and tried to scan with World Marker mode. The World Marker scan was over in only a few seconds, and you’ll see the ensuing marker map on the MIRACO Plus display within the picture under. This was approach sooner than capturing the markers in photogrammetry mode.
As with photogrammetry mode, some extent cloud scan might be utilized to the marker skeleton. The inexperienced 3D matrix of the markers seems augmented on the AMOLED display and rotates because the scanner is moved, permitting the person to place the scanner correctly.
I used to be a bit of extra liberal with the markers this time, and so capturing the purpose cloud was painless. I managed to seize the seen faces of the radiator in beneath a minute.
With out the markers, this may have been time-consuming (if not not possible) to supply the purpose cloud because of the lack of options on the radiator. However with the markers, your entire radiator was mainly scanned in a single go, needing solely minor shifts within the place of the scanner.
You’ll be able to see the ensuing level cloud within the picture under, which has been rendered excessive of the worldwide marker factors.
Conclusion
The MIRACO Plus 3D scanner and its Photogrammetric Metrology Package is designed to scan massive objects precisely and shortly due to its fast technique of gathering photogrammetry knowledge, mixed with its level cloud producing capabilities with the common 3D scanner factor.
It’s as straightforward to make use of because the MIRACO, however can be 20% extra correct at 0.04 mm and round 33% sooner, with speeds as much as 20 fps, than the MIRACO and MIRACO Professional. It additionally has 1.5x and 2x infrared optical zoom for enhanced element seize.
The inclusion of the Photogrammetric Metrology Package permits for high-resolution seize of small particulars on massive objects whereas guaranteeing volumetric accuracy. This makes it ideally suited to these working in aerospace, automotive, structure, historic preservation, and presumably industrial digital twins.
Identical to the unique MIRACO, it has a user-friendly interface, and is intuitive to make use of. The PMK actually hastens the seize of bigger areas, however floor preparation is significant in terms of making level clouds.
We have now seen how the purpose cloud options work in our earlier article, and we have been more than happy with the outcomes. I sit up for getting higher outcomes with the brand new MIRACO Plus, as soon as I’ve spent a bit of extra time with the PMK.

And simply in case you wish to expertise among the authentic MIRACO goodness, you may be completely satisfied to know that each the MIRACO and MIRACO Professional are at present obtainable with a 20% low cost.
By the way in which, Revopoint launched its first Laser 3D Scanner, MetroX, on Kickstarter on October fifteenth and can run till November 14th, providing a reduction of as much as 35%, bringing the worth down to only $649.
