# Capture Normals Image

`GET /periphery/cameras/capture/normals`

Retrieves surface normal data from the camera's captured image.

- Pixels without geometry carry no normal and are returned as 0.0 in the
  json format, since JSON cannot represent the non-finite value the
  annotator puts there.

## Query parameters

- `result_type` 'json' | 'rgb_png' | 'jpeg', required — Format which will be used to represent the captured data. 'json' carries the measurements; 'rgb_png' and 'jpeg' are renderings to look at, and jpeg is lossy.
- `camera_prim_path` string, nullable — Path of camera prim. Leave it out to capture through the active viewport camera.
- `width` integer — Image width in px
- `height` integer — Image height in px

## Response `200`
