3D observation instrument for pathology tissues

Abstract Pathology telemedicine uses digital data of pathological samples to acquire technical support from sophisticated remote experts, aiding cancer diagnosis in less developed regions. In this paper, we propose a color 3D observation system composed three cameras and projector, achieving complete range imaging pathology tissues. A new phase mapping method for the projector calibration is proposed by locating geometric centroid checkboard’s white squares, avoiding center positioning error traditional circular markers introduced perspective distortion. denoising successively using amplitude modulation judge, monotonicity check, abruptness constraint proposed, which facilitates obtaining clean point clouds.
