Detailed Description

The depth data circle tracker uses depth data from a depth camera to track circles, such as holes in a calibration board or the gesture where the thumb and index finger meets to form a ring.

Member Data Documentation

std::auto_ptr< SFPaintTexture > HVR::DepthDataCircleTracker::debugTexture

This texture will not be cleared between frames, since many trackers may be drawing to the same texture.

Add the same texture to the depth camera node to reset and fill with the depth image.

std::auto_ptr< SFDepthCamera > HVR::DepthDataCircleTracker::depthCamera

The camera to read the depth data from.

std::auto_ptr< H3D::SFVec2f > HVR::DepthDataCircleTracker::meanRadiusRange

The range of mean radius values of valid circles.

std::auto_ptr< H3D::SFVec2f > HVR::DepthDataCircleTracker::stddevRadiusRange

The range of the standard deviation of the radius values of valid circles.

This is a measure of how circular the circle is.
