ABSTRACT:This contribution provides an overview of various photogrammetric measurement techniques in minimally invasive surgery and presents a self-developed prototypical trinocular endoscope for reliable surface measurements. Most of the presented techniques focus on applications regarding laparoscopy, which mean endoscopic operations in the abdominal or pelvic cavities. Since endoscopic operations are very demanding to the surgeon, various assistant systems have been developed. Imaging systems may use photogrammetric techniques in order to perform 3D measurements during operation. The intra-operatively acquired 3D data may be used for analysis, model registration, guidance or documentation. Passive and active techniques have been miniaturised, integrated into endoscopes and investigated by several research groups. The main advantages and disadvantages of several active and passive techniques adapted to laparoscopy are described in this contribution. Additionally, a self-developed trinocular endoscope is described and evaluated.

“…However, there are a number of methods that have been proposed to facilitate pattern detection through the use of more complex coded patterns, and a number of coding algorithms have been proposed in the literature (e.g. (Albitar et al, 2007;Pavlidis et al, 2007;Chen and Li, 2008;Kawasaki et al, 2008;Gorthi and Rastogi, 2010;Maurice et al, 2011)); processing and display may be achieved in real time. In the case of a mono camera detection, the challenge is to establish the relationship between the pattern generation and the camera parameters, a process that is again generally achieved prior to operation using a calibration target.…”

One of the main challenges for computer-assisted surgery (CAS) is to determine the intra-operative morphology and motion of soft-tissues. This information is prerequisite to the registration of multi-modal patient-specific data for enhancing the surgeon's navigation capabilites by observing beyond exposed tissue surfaces and for providing intelligent control of robotic-assisted instruments. In minimally invasive surgery (MIS), optical techniques are an increasingly attractive approach for in vivo 3D reconstruction of the soft-tissue surface geometry. This paper reviews the state-of-the-art methods for optical intra-operative 3D reconstruction in laparoscopic surgery and discusses the technical challenges and future perspectives towards clinical translation. With the recent paradigm shift of surgical practice towards MIS and new developments in 3D optical imaging, this is a timely discussion about technologies that could facilitate complex CAS procedures in dynamic and deformable anatomical regions.

Owing to the diversity of projection surfaces, an effective mobile display system must be adaptive to the surface to avoid introducing a clipped scene. In this paper, we propose a smart mobile display system which automatically adapts to the location and motion of a surface. Firstly, an imperceptible structured light technique is adopted and continuous adaptation is accomplished. Secondly, a specifically designed code image with high distortion tolerance is proposed. Thirdly, we present a priority-based correction method to revise previous decoding results. Finally, a matching procedure resisting noise interruption is introduced. The system achieves 95% correct rate under the common indoor illuminance. In addition, the system performance is independent of the projected content and the surface shapes.
