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 Equipment 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 Equipment not solely helps common detailed scanning but additionally adapts seamlessly to advanced measurement eventualities.
The unique MIRACO scanners work by structured mild know-how to map the geometry of an object. The scanner initiatives a collection of sunshine patterns onto the thing, and as these patterns deform over the floor, a stereo digital camera pair captures the ensuing distortions.
Photogrammetry works a little bit otherwise, and is dependent upon 2D photographs taken from a number of angles to reconstruct a 3D mannequin.
The approach calculates depth data 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 possibly can see the calibrated carbon fiber scale bars, and sticky / magnetic coded targets within the picture under. These should be positioned liberally on/across the object being scanned.
Setting Up
Opening the primary field, we will see all of the equipment included with the MIRACO Plus and Photogrammetric Metrology Equipment. These embody energy provide, USB cable, markers, and a flowery carry case. You possibly can see all of them within the image under.
We acquired the instruction handbook in PDF from Revoipoint instantly, and the directions are pretty simple 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 dimensions 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 wished to check the photogrammetry mode. To do that, it’s best to place no less than two scale bars in opposition to or across the object’s floor, making certain 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 finished through the scanner interface. After this step is full, then the scanning can start.
Revopoint says this PMK is sweet for scanning gadgets as massive as automobiles and plane elements. Sadly, I shouldn’t have both of these useful for the time being, so I caught a bunch of the registration stickers throughout my desk at first (proven within the image above). It has a reasonably attention-grabbing geometry and number of floor finishes.
After taking the required minimal 30 pictures from varied angles, I processed the info on the hand held unit and produced my first marker map. The onscreen directions are simple 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 as a consequence of 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 encircling areas although. Due to this fact, earlier than scanning clear, darkish or extremely reflective objects, utilizing scanning spray can offer you a greater scanning expertise
That is going to take a little bit bit extra follow and numerous spray to get proper. A couple of extra markers is perhaps helpful too.
Onto the following mode, which might show a little bit simpler to become familiar with.
World Marker Mode
The second new mode accessible on the MIRACO Plus is the World Marker mode.
Whereas photogrammetry mode requires a number of particular person pictures and the dimensions bars, World Marker mode makes use of a steady scan to create the worldwide marker factors.
Operating out of huge issues with respectable surfaces that I may 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 may see the ensuing marker map on the MIRACO Plus display within the picture under. This was manner quicker 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 little bit 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 could have been time-consuming (if not not possible) to supply the purpose cloud as a result of lack of options on the radiator. However with the markers, the complete radiator was principally scanned in a single go, needing solely minor shifts within the place of the scanner.
You possibly can 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 Equipment is designed to scan giant objects precisely and rapidly due to its fast technique of gathering photogrammetry knowledge, mixed with its level cloud producing capabilities with the common 3D scanner aspect.
It’s as simple to make use of because the MIRACO, however can be 20% extra correct at 0.04 mm and round 33% quicker, 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 Equipment permits for high-resolution seize of small particulars on giant objects whereas making certain volumetric accuracy. This makes it ideally suited to these working in aerospace, automotive, structure, historic preservation, and presumably industrial digital twins.
Similar to the unique MIRACO, it has a user-friendly interface, and is intuitive to make use of. The PMK actually accelerates the seize of bigger areas, however floor preparation is important in relation to making level clouds.
We’ve seen how the purpose cloud options work in our earlier article, and we have been very happy with the outcomes. I sit up for getting higher outcomes with the brand new MIRACO Plus, as soon as I’ve spent a little bit extra time with the PMK.

And simply in case you want to expertise a few of the authentic MIRACO goodness, you’ll be comfortable to know that each the MIRACO and MIRACO Professional are at the moment accessible 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 value down to only $649.
