POP 4 - BETA TESTING -

SCANNING A MOSAIC

I’m currently testing the upcoming

Revopoint POP 4 (an AI-powered

Blue Laser & Infrared

Hybrid Scanner under $1k) and

wanted to share a quick look at what

this hardware can do.

For this test, I scanned an amazing

reproduction of a highly detailed

ancient mosaic from

Jordan (size 25x21cm).

The Workflow

• Scanner Mode: 30-Cross Blue

Laser Lines

• Tracking: Marker mode

The color in these images is from a

high-res photo overlaid directly onto

the POP 4’s 3D

mesh.

The Results

• Micro-Details: Mosaics are tough

due to the tiny tile variations and

grout lines. The

POP 4 boasts up to 0.03 mm

single-frame accuracy, and it

captured the physical

texture perfectly without smoothing

out the real-world imperfections.

• Silky Smooth Scanning: In

multi-line laser mode, it hits up to

105 fps (with an NVIDIA

GPU). The tracking was incredibly

fluid and completely lag-free.

The crossed blue lasers easily scan

the multicolored the mosaic tiles.

Other Cool Specs

I’m just scratching the surface here.

For its price bracket, it’s incredibly

versatile:

• True Hybrid: Includes NIR full-field

& VCSEL structured light, plus a

single-line laser

for deep holes.

• Native Gaussian Splatting:

Converts point clouds/RGB directly

into 1:1 models and

exports to .splat.

• Untethered Scanning: Wi-Fi 6 and

a 5500mAh battery grip (4 hours of

power) mean

you can cast straight to your phone,

no laptop required.

• Outdoor Ready: Handles up to

100,000 lux (bright daylight) in laser

mode.

Let me know what you think of the

mesh quality! I’ll be doing more

tests soon

That’s awesome! Thanks for sharing! I hope I get to test one.

Thanks for appreciation
Pop 4 is a little monster!

Any close up details of what I can do? I’m curious if this will be usable for accurate reverse engineering of small to medium parts.

Hi @Enpixelate POP4 is not really designed for scanning very small volume objects , it is more for medium to large objects , it’s maximum accuracy is 0.03 mm , small objects requires at least 0.02mm . It don’t have the capacity of Mini 2. As it was designed mostly for Rapid scanning and prototyping .

You will be better off with Mini 2 or any Metro series scanner like MetroX or MetroY Pro or better Metro Ultra

[Enpixelate]

Thanks. I understand POP4 is not intended to replace the Mini 2 or Metro series for very small high-precision parts.

My use case is practical scan-to-CAD work for 3D printing. I would be scanning small-to-medium objects or surfaces with curved shapes, grooves, edges, recessed areas, and fit-related details. The goal would be to use the scan as a CAD reference to design 3D printed parts that fit around or attach to existing objects, not for inspection-grade measurement.

The versatility of POP4 is what makes it appealing. A scanner that has to stay connected to my computer limits me to one workspace, while POP4 seems like it would let me scan in other rooms, a garage, or wherever the object already is. MetroY Pro is outside my budget, so I am trying to understand whether POP4 would be accurate and detailed enough for this kind of workflow.

Are there any close-up examples showing functional parts or detailed surfaces, especially holes, grooves, edges, recessed areas, and measurements compared to the real object?

Preserving History with the Revopoint POP 4

Another test with the new Revopoint POP 4 on interisting antique object: a decorated bronze bell. This piece isn’t just metal; it’s covered with a repetitive decorations, a beautiful dark aged patina, and some corrosion crusts that make surface capture interesting test for the POP 4 3D scanner.

I used the 30-cross blue laser lines mode, which is designed specifically to handle high reflectivity and dark surfaces. The results were amazing:

• Precision: Captured the fine details of the decorations with a single-frame accuracy of up to 0.03 mm.

• Stability: Even with the “messy” texture of the corrosion, the laser tracking remained rock-solid at a high frame rate (it can go up to 105 fps!).

• Analysis: After the scan, I moved the model into Revo Measure to take precision measurements of the bell’s dimensions for digital archiving.

It’s amazing to see how this hybrid blue laser and infrared tech can bring professional-grade cultural heritage preservation to a handheld device.

Check out the images of the process!

3DGS scanning a terracotta head with Revopoint POP4

Terracotta is an excellent material for 3D scanning, but the goal of this test was to capture its complex natural texture. Although the piece is non-polychrome, it features a rich surface of red, gray, and black tones resulting entirely from the firing process.

The POP4 accurately captured every chromatic and geometric variation, providing the necessary dataset for 3DGS technology. By using 3D Gaussian Splatting, the final output goes beyond traditional meshes, delivering a material realism that stays true to the authentic look of fired clay.

Discover with POP 4 what is invisible on the surface of an ancient painting

We are thrilled to share some fascinating insights from our latest project involving a beautiful late 19th to early 20th-century Belgian painting.

The Artwork:

Housed in an ornate, richly gilded frame, this piece is an oil painting on pressed cardboard. It captures an intimate, dimly lit domestic interior. On the right, an elder woman sits quietly working near a window adorned with potted flowers, while a young girl sits on the floor nearby, deeply absorbed in reading a book. An open door in the center breaks the shadowed atmosphere, looking out onto a sunlit courtyard with a red-tiled roof structure, while a wooden staircase climbs along the left wall.

The Tech Discovery:

Using the Revopoint POP 4 3D scanner in Full Field mode, we captured the heavily textured, impasto surface of this piece in extreme detail. When we analyzed the 3D data by stripping away the color layer, the surface morphology told a completely different story.

As you can see highlighted by the red dashed lines, there is a stark discrepancy between the visible painted scene and the underlying brushstroke topography. The physical ridges and textures running horizontally across the surface do not match the shapes of the figures, the open door, or the staircase we see today.

The Verdict:

This strongly indicates a reused support. The artist likely painted this beautiful domestic scene directly over an entirely different, pre-existing painting.

Art history meets cutting-edge technology to reveal the hidden secrets left behind by the masters.
