# DetectHumanBodyPose3DRequest

A request that detects points on human bodies in 3D space, relative to the camera.

## Declaration

```swift
final class DetectHumanBodyPose3DRequest
```

## Overview

Overview This request generates a collection of HumanBodyPose3DObservation objects that describe the position of each body the request detects. If the system allows it, the request uses AVDepthData information to improve the accuracy.
