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.
