2D brightness variation when projector brightness is set to 0

Problem

2D captures show unexpected brightness variations even though the projector brightness is set to 0.

Potential cause

This is caused by the projector's thermal stabilization interfering with 2D captures. It affects SDK version 2.17.2 specifically. See 勘误表 for details (E-37).

Solutions

Update to SDK 2.18 or later, or downgrade to SDK 2.17.1.

If neither is possible, disable thermal stabilization as a workaround. Follow the instructions at 如何禁用它.

小心

Disabling thermal stabilization increases the impact of ambient temperature on point cloud accuracy.
