Depth Estimation (DepthAny. V2)

This function block estimates per-pixel depth (distance) from a single RGB/BGR image. It produces a colorized depth visualization and a grayscale depth map that you can view, log, or feed to other processing blocks.

📥 Inputs

Image RGB/BGR image used as the input for depth estimation.

📤 Outputs

Depth Vis Colorized visualization of estimated depth (easy to inspect).

Depth Map Grayscale depth map normalized to 0–255 (useful for analysis and downstream blocks).

🕹️ Controls

Model Size Choose the model accuracy / speed trade-off. Options typically include Small, Base, and Large. Max Size Slider to limit the largest image dimension used during processing. Larger values give more detail but require more processing time.

🎨 Features

• Produces both a visual depth map and a raw grayscale depth image for flexible use.

• Model selection control lets you trade inference speed for accuracy.

• Max Size prevents very large images from slowing down processing; the block automatically resizes inputs for efficient inference.

• Automatically uses available processing resources to give best possible throughput (UI-level behavior).

⚙️ Running mechanism

When the block runs it takes the current input image, optionally resizes it to respect the Max Size setting, processes it with the selected model size, and returns the two outputs: a color visualization and a normalized grayscale depth map. Larger models and larger Max Size values increase processing time.

📝 Usage Instructions

1. Connect an image-producing block to the Image input.

2. Select a Model Size based on the accuracy vs. speed you need.

3. Adjust Max Size to limit processing time while preserving enough detail.

4. Use the Depth Vis to quickly inspect results; use Depth Map as numeric input for other processing blocks.

💡 Tips and Tricks

• For very large images, use Image Resizer before this block to reduce processing time while preserving the important area.

• If the input image is low-resolution, try running Super Resolution upstream to improve detail before depth estimation.

• To visually inspect outputs in your workflow, connect Depth Vis to the Show Image block.

• Save results automatically by sending Depth Vis or Depth Map to Image Logger or Image Write.

• When experimenting, start with Model Size set to Small to get quick feedback, then switch to Base or Large once settings are stable.

(hint: recommended companion blocks — Image Resizer, Super Resolution, Show Image, Image Logger, Image Write)

🛠️ Troubleshooting

• If processing is too slow: lower Model Size or reduce Max Size.

• If results look coarse: increase Max Size or try a larger Model Size (if processing resources allow).

• If no output appears or the block stalls: ensure the upstream image block is supplying valid image frames.

• If you need to keep recent results available for review, route outputs to Image Logger or Show Image to confirm expectations.
