Mech-Eye PRO/LSR, featuring a brand-new algorithm upgrade, delivers even superior imaging effects for reflective scenarios

Intro

Mech-Eye SDK version 2.3 is officially released, featuring a significant algorithm upgrade that greatly enhances the imaging effects of PRO and LSR cameras in various reflective scenarios.

Point cloud demo

In 3D vision, imaging of reflective metal workpieces poses challenges. The intense reflection effects on the metal surface lead to issues such as glare spots and shadows, making accurate and complete 3D imaging complex. The following are some typical challenging scenes in reflective imaging:

In response to these typical reflective scenes, Mech-Mind has introduced a completely new projection scheme and imaging algorithm, officially released in Mech-Eye SDK 2.3. After upgrading to Mech-Eye SDK 2.3, when using Mech-Eye PRO and Mech-Eye LSR cameras, you can optionally utilize the new “Reflective” mode, enhancing the imaging effects in various reflective scenarios.

Highly reflective metal workpiece with oil on the surface


Imaging challenges: Strong reflections on metal workpieces, combined with surface oil stains, pose difficulties for point cloud imaging.

Metal objects inside a reflective deep bin

Imaging challenges: Strong reflections on metal workpieces; mirror-like reflections on the sidewalls of deeply reflective containers interfere with point cloud imaging.

Air conditioner compressor

Imaging challenges: The surface of the compressor is made of black and reflective material, with an irregular arc shape. At the same time, the compressor is placed on a white foam partition, and the contrast of the scene is very high, which increases the difficulty of point cloud imaging.

Lithium battery cell

Imaging challenges: The surface of the battery cell simultaneously features black patches and a reflective aluminum material top cover, posing challenges for point cloud imaging.
