easyar

MotionTrackerCameraDevice implements a camera device for real-scale 6DOF motion tracking, outputting InputFrame (including image, camera parameters, timestamp, 6DOF position information, and tracking status). After creation, start/stop can be called to start and stop the data stream. When the device is no longer needed, close can be called to close it. It should not be used after close. MotionTrackerCameraDevice outputs InputFrame through inputFrameSource. inputFrameSource should be connected to InputFrameSink for use.

setBufferCapacity

Definit the capacity of the InputFrame buffer. bufferCapacity indicates the capacity of the InputFrame buffer.

This may cause problems such as a frozen image.

hitTestAgainstPointCloud

Effectue Hit Test in the current point cloud and obtains the nearest 3D point position coordinate on a ray from near to far relative to the camera. The point is represented by three consecutive values, corresponding to the coordinate values on the X, Y, and Z axes. In the input image coordinate system ([0, 1]^2), x points right, y points down, and the origin is at the upper-left corner. You can use imageCoordinatesFromScreenCoordinates to convert from screen coordinates to image coordinates.

hitTestAgainstHorizontalPlane

Effectue Hit Test on horizontal planes detected in real time within the current field of view. After hitting a horizontal plane, returns the position coordinate of the 3D point on that plane nearest to the Hit Test ray. In the input image coordinate system ([0, 1]^2), x points right, y points down, and the origin is at the upper-left corner. You can use imageCoordinatesFromScreenCoordinates to convert from screen coordinates to image coordinates. The output is the coordinates of the point cloud on the plane in the world coordinate system. Each point is represented by three consecutive values, corresponding to the coordinate values on the X, Y, and Z axes.
