Abstract : Cystoscopy is currently the reference clinical examination for visual exploration of the inner walls of the bladder. A cystoscope (instrument used in this examination) allows for video acquisition of the bladder epithelium. Nonetheless, each frame of the video displays only a small area of few squared centimeters. This work aims to build 3D maps representing the 3D shape and the texture of the inner walls of the bladder. Such maps should improve and facilitate the interpretation of the cystoscopic data. To reach this purpose, a new flexible algorithm is proposed for the calibration of cystoscopic active vision systems. This algorithm provides the required parameters to achieve accurate reconstruction of 3D points on the surface part imaged at each given moment of the video cystoscopy. Thus, available data for each acquisition are a set of few 3D points (and their corresponding 2D projections) and a 2D image. The aim of the second algorithm described in this work is to place all the data obtained for a sequence in a global coordinate system to generate a 3D point cloud and a 2D panoramic image representing respectively the 3D shape and the texture of the bladder wall imaged in the video. This 3D cartography method allows for the simultaneous estimation of 3D rigid transformations and 2D perspective transformations. These transformations give respectively the link between cystoscope positions and between images of consecutive acquisitions. The results obtained on realistic bladder phantoms show that the proposed method generates 3D surfaces recovering the ground truth shapes.
