3D freehand ultrasound calibration: Python implementation for calibration of a 3D freehand ultrasound system using a stereo vision system and a planar marker.
C++ acquisition system of two stereo Basler cameras and an ultrasound machine.
Notes about trifocal tensor estimation and point transfer using a calibrated three-view system. A camera1-projector-camera2 setup is used as a three-view system. The trifocal tensor is estimated for that calibrated case and point transfer is applied to the third view (camera2).
Notes about fundamental matrix estimation with calibrated stereo cameras, using different approaches: epipolar restrictions and bilinear relations.
Notes about stereo triangulation where different methods are evaluated: DLT, inhomogenenous, optimal method, and plane-line triangulation (using a single coordinate for a view and both for the another view).
C++ code example for NGIMU data acquisition over Wi-Fi through OSC messages using ospack library.
