Too Dark 2D Images Captured by LSR L/LSR S/DEEP V4 during Calibration

Symptom:

In the hand-eye calibration with LSR L/LSR S/DEEP V4 cameras, the 2D images captured by the cameras were too dark.

Affected Software Versions:

Mech-Vision 1.6.1 and later versions

Possible Cause:

The LSR/DEEP series consist of a 2D camera (texture) and two 2D cameras (depth source). For 2D images captured by 2D monochrome cameras in Hand-eye calibration, you should increase the value of the 2D Image (Depth Source) Exposure Time parameter in Mech-Eye Viewer if the environment is relatively dark.

Solution:

Follow these steps to fix the issue:

  1. Connect to the LSR L/LSR S/DEEP V4 camera through Mech-Eye Viewer.

  2. Select “calib” under Parameter group.

  3. Increase the 2D Image (Depth Source) Exposure Time or set Increase the 2D Image (Depth Source) Exposure Time to Flash and re-calibrate the camera.

  4. Add light to the environment if the issue persists.
