  • Difficulty in Measuring Depth of Small Objects at 2 Meters with OAK-D Pro POE

Hello Luxonis Community,

I am currently working on a project where I need to measure the depth of food items on a plate using the OAK-D Pro POE camera. The challenge I'm facing is that these objects are small, and when the camera is positioned 2 meters away, the depth measurements are not accurate.

Here is the setup I'm using:

  1. Camera: OAK-D Pro POE

  2. Distance: 2 meters

  3. Configuration Settings:

    • Confidence: 230

    • Median Filter: 5 (KERNEL_5x5)

    • Extended Disparity: Disabled

    • Subpixel Precision: Enabled

    • Decimation Factor: 1

    • Temporal Filter: Disabled

    • Spatial Filter: Enabled (Radius: 2, Alpha: 0.5, Delta: 2, Iterations: 1)

    • Threshold Filter: Min Range: 2000, Max Range: 2400

Despite trying various configurations, I am unable to achieve satisfactory depth accuracy. The depth map does not seem to capture the fine details of the small objects on the plate.

Could anyone suggest additional parameters I might adjust or any specific techniques to improve depth precision for small objects at this distance?

Any help or advice would be greatly appreciated.

Thank you!
