DepthCorrelatedCoordinateMapper.UnprojectPoint 方法

定義

命名空間:

Windows.Media.Devices.Core

使用從 MediaFrameSource 呼叫TryCreateCoordinateMapper建立之DepthMediaFrame的深度資訊，將 2D 點從MediaFrameSource取消產生至 3D 空間中的點。

public:
 virtual float3 UnprojectPoint(Point sourcePoint, SpatialCoordinateSystem ^ targetCoordinateSystem) = UnprojectPoint;

float3 UnprojectPoint(Point const& sourcePoint, SpatialCoordinateSystem const& targetCoordinateSystem);

public Vector3 UnprojectPoint(Point sourcePoint, SpatialCoordinateSystem targetCoordinateSystem);

function unprojectPoint(sourcePoint, targetCoordinateSystem)

Public Function UnprojectPoint (sourcePoint As Point, targetCoordinateSystem As SpatialCoordinateSystem) As Vector3

參數

sourcePoint

Point

要對應之 MediaFrameSource內的 2D 來源點。

targetCoordinateSystem

SpatialCoordinateSystem

取消專案點的座標系統。

傳回

Vector3 Vector3

float3

3D 空間中的點。
