Méthodes publiques

Méthode Description
FitPlaneModelNearClick ( Vector3 pointCloud, int pointCount, double timestamp, TangoCameraIntrinsics cameraIntrinsics, Matrix4x4 &matrix, Vector2 uvCoordinates, Vector3 &intersectionPoint, Plane &plane ) : int

Fits a plane to a point cloud near a user-specified location. This occurs in two passes. First, all points in cloud within maxPixelDistance to uvCoordinates after projection are kept. Then a plane is fit to the subset cloud using RANSAC. After the initial fit all inliers from the original cloud are used to refine the plane model.
ScreenCooordinateToWorldBilateral ( Vector3 pointCloud, int pointCount, double timestamp, TangoCameraIntrinsics cameraIntrinsics, TangoImageBuffer colorImage, Matrix4x4 &matrix, Vector2 uvCoordinates, Vector3 &colorCameraPoint, bool &isValidPoint ) : int

Calculates the depth in the color camera space at a user-specified location using bilateral filtering weighted by both spatial distance from the user coordinate and by intensity similarity.
ScreenCoordinateToWorldNearestNeighbor ( Vector3 pointCloud, int pointCount, double timestamp, TangoCameraIntrinsics cameraIntrinsics, Matrix4x4 &matrix, Vector2 uvCoordinates, Vector3 &colorCameraPoint, bool &isValidPoint ) : int

Calculates the depth in the color camera space at a user-specified location using nearest-neighbor interpolation.
TangoPoseToWorldTransform ( TangoPoseData poseData, Vector3 &position, Quaternion &rotation ) : void

Convert a TangoPoseData into the Unity coordinate system. This only works on TangoPoseData that describes the device with respect to the start of service or area description. The result position and rotation can be used to set Unity's Transform.position and Transform.rotation.
UpdateCurrentRotationIndex ( ) : void

Update current rotation index. This function will make a query from native Android and decide what is the current screen orientation.

FitPlaneModelNearClick() public static méthode

Fits a plane to a point cloud near a user-specified location. This occurs in two passes. First, all points in cloud within maxPixelDistance to uvCoordinates after projection are kept. Then a plane is fit to the subset cloud using RANSAC. After the initial fit all inliers from the original cloud are used to refine the plane model.

pointCount int /// The number of points to read from the point cloud. ///
timestamp double The timestamp of the point cloud.
cameraIntrinsics TangoCameraIntrinsics /// The camera intrinsics for the color camera. Cannot be null. ///
matrix UnityEngine.Matrix4x4 /// Transformation matrix of the color camera with respect to the Unity /// World frame. ///
uvCoordinates Vector2 /// The UV coordinates for the user selection. This is expected to be /// between (0.0, 0.0) and (1.0, 1.0). ///
