Revopoint3D POP 4 is currently LIVE on Kickstarter , don’t miss the chance to support this great new project : https://revo.ink/3Rbqdid
POP 4
Its hybrid blue laser and infrared structured-light system lets you capture nearly everything, even dark or shiny surfaces, delivering high-detail 3D scans from small mechanical parts indoors to large outdoor workpieces.
With Gaussian splatting mode, wireless connectivity, outdoor-ready performance, and smart AI features, POP 4 makes it easy to create detailed 3D models anywhere.
Below some examples with POP 4
Cross Line & Single Line BlueLaserScanning involves projecting a blue laser beam onto an object’s surface and capturing the reflected light in depth cameras to capture an object’s surface. Cross 30 Line mode allowing to capture surfaces much faster, especially flatter surfaces can be captured in no time, Single Line is mostly used for scanning deeper surfaces like holes and cavities. Laser mode request Markers , Rapidly scan flat, shiny, or dark surfaces at up to 2M points/s* for fast, accurate results, no scanning spray needed.
Accuracy: Up to 0.03
below some examples with POP 4
Full Field mode uses infrared projector that project 2 patterns on the object surface and capturing the infrared patterns in depth camera sensors , also called Structured Light , Full Field mode relay on object features for tracking, markers can be used to replace the missing features and keep the tracking stable. Easily capture bodies, faces, and feature-rich objects, marker-free, at speeds up to 5M points/s.
Use VCSEL mode for fast, up to 30 fps scans that easily capture larger workpieces and people marker-free, even in direct sunlight. This is a rapid mode that requires less features per object what is great for scanning middle to big objects .
VCSEL speckle code pattern is irradiated onto the surface of an object, it is scattered and the depth camera captures the image formed by the scattered light. Based on the matching results, the distance between each point on the object surface and the camera is calculated using the triangulation principle, thereby achieving accurate 3D reconstruction. The wavelength characteristics of infrared VCSEL make it less susceptible to interference in strong light environments, ensuring the stability and reliability of 3D reconstruction. In addition, since infrared is invisible light, VCSEL can achieve lightless scanning, especially when scanning sensitive occasions such as the human body scan, providing a more friendly and interference-free scanning experience even in full sunlight .

3D Gaussian Splatting
3D Gaussian Splatting (3DGS) is a state-of-the-art rendering technique that creates photorealistic 3D scans from 2D images in real-time. It represents scanned object using millions of tiny, fuzzy, 3D ellipsoids (Gaussians) rather than polygons.
To have a successful 3DGS model created from your scan , you need to make sure the background where you scan your object is free from anything else but the one color background.
i liked the auto tt mode of metrox for my use case. Not too much raw point cloud data an therefore noise, but very precise results. Does pop4 reach this goal?
POP 4 accuracy of 0.03mm is archived only with the Laser mode .
MetroX Auto Single shot mode provide very slightly better result because of the Blue Laser Full Field, Infrared Full Field is slightly more noisy in general compared to Blue light so your Auto mode is definitely better.
POP 4 offers things that MetroX can’t archive, so it’s a more a companion scanner than Metro series replacement . All depends on what you need and less what is better as both scanners offers different things.
Hi Daniel , what I would see interesting here for your work with POP 4 is 3D Gaussian Splatting, it produces great color models for websites or catalog , hopefully this function will be added to other scans in the future as it is really great .
