CV / Depth-Anything

Depth-Anything-V2-ViTS

Depth-Anything-V2-Small (ViT-S backbone) outputs a 224x224 relative depth map. The app normalizes it, applies an INFERNO colormap, and alpha-blends onto the original frame. First variant of the depth_anything family.

Modeldetails

Depth-Anything-V2-ViTS on reComputer R Series (CM5 + Hailo-8)

Depth-Anything-V2-Small (ViT-S backbone) performs zero-shot monocular depth estimation on Hailo-8. The HEF outputs a 224×224×1 relative depth map; the app normalizes it, applies an INFERNO colormap, and alpha-blends onto the original frame.

REST API

bash

curl -X POST "http://<Board_IP>:8000/api/models/depth_anything_v2_vits/predict" \
  -F "file=@test.jpg"

Returns depth_stats (min, max, mean, std) for the predicted depth map.

Endpoint	Method	Purpose
`/api/models/depth_anything_v2_vits/predict`	POST	Depth statistics (JSON)
`/api/video_feed`	GET	MJPEG with INFERNO depth overlay

Implementation Notes

Relative depth: output is per-frame min-max normalized (not metric). Higher = farther. Dark (INFERNO) = close, bright = far.
Slider controls alpha blend between original frame and depth colormap.
normalize_in_net ImageNet RGB; no input_conversion → feed raw uint8 RGB.
No on-chip post-processing — raw FLOAT32 depth map output.

Development Notes

Source: src/rpi5_hailo8_depth_anything_v2_vits/
Container: ghcr.io/seeed-projects/recomputer-hailo8-cv/depth_anything_v2_vits:latest
Family: depth_anything (variants v2_vits / vits)

Invoer en uitvoer

Input: image, video, or USB camera frame. Output: relative depth map with INFERNO colormap overlay on MJPEG preview, plus depth statistics (min/max/mean/std) via API.
