Depth (OSD-DPT)

  1. Is produced by the Depth & Occlusion Estimation Sub-AIM of the Visual Scene AIM.
  2. Represents the estimated distance of a visual object from the user’s point of view, expressed in meters.
  3. Includes depth value accuracy to support improved downstream processing.

Function Description
Depth Value Specifies the estimated distance from the user’s point of view in meters
Depth Accuracy Indicates the reliability of the depth estimation (range: 0–1)
Header Metadata Identifies the schema version and ensures traceability across AIMs

5     Conformance Testing

A Data instance Conforms with MPAI-OSD Depth (OSD-DPT) if:

  1. The Data validates against the OSD-DPT’s JSON Schema.
  2. All Data in the  OSD-DPT’s JSON Schema
    1. Have the specified type
    2. Validate against their JSON Schemas
    3. Conform with their Data Qualifiers if present.
