Endoscopic probe for multispectral 3D measurements and imaging

摘要

The industrial endoscopic remote visual inspection and endoscopic minimally invasive procedures in medicine provide the wide range of visualization and measurement techniques for hard-to-reach objects' inner surfaces inspection. In common practice, the three-dimensional visualization, three-dimensional geometrical measurement and spectral imaging techniques are realized independently in different specialized endoscopic devices. Simultaneous implementation of these techniques in a single versatile endoscopic system may increase the efficiency of the inspection and diagnostic procedures. We propose a combined approach to multispectral stereoscopic endoscopic imaging. The prototype of an endoscopic probe able to carry out remote three-dimensional geometrical measurements as well as spectral visualization and measurements is demonstrated.
