*结果基于在0.5 m处250 µs的曝光时间。所有其他距离都使用1000 µs的曝光时间，并用白皮书目标测量距离。
Test Conditions:
- Target: White paper mounted on bar attached to motion stage
- Helios2 positioning: mounted on tripod, laser distance meter used to measure distance from case front to stage zero position
- Camera setting: Coord3D_C16 Pixel Format, bilateral filtering OFF, camera warmed up for 20 minutes.
- Imaging environment: Room light on during testing, black material used to minimize reflections off floor
- Motion stage moved in 50mm steps, for each step measure depth over 10×10 pixel ROI at image center, repeat 32 times at each position
- Accuracy measured as difference between camera’s average measured depth across the ROI and 32 images and the ground truth depth (stage zero distance + stage position)
