In the situation where metal parts are neatly arranged in a full basket, how should high-reflectivity metal point clouds be processed?

My workpieces are neatly arranged in a bin, but they are highly reflective, and the imaging effect of the 3D camera is not good. How should I adjust it?

Highly reflective metal parts often lead to missing point cloud data. The general approach to addressing point cloud missing issues is as follows:

  1. Begin by utilizing flash images to determine if the current missing parts are caused by overexposure.
  2. Adjust the projection of light by appropriately reducing its intensity or avoiding overexposed areas.
  3. Shift positions to avoid mirror-like reflections (move away from overexposed points).
  4. Adjust the angle to cover the entire field of view (modify the field of view range).

If camera adjustment positions are limited, you can potentially fully resolve the current point cloud issue by adjusting the camera exposure and observing the results.
Main adjustment strategies:

  1. Decrease the camera exposure intensity by reducing the 3D exposure, lowering laser intensity, and decreasing the projection light intensity. This method aims to address improvements in overexposed areas while potentially leading to underexposure in surrounding regions.
  2. Introduce additional sets of higher exposure to compensate for darker areas within the current scene.
  3. Ultimately, use a combination of low exposure and high exposure settings through multiple exposures to resolve the tuning issue.
