An algorithm for the restoration of blurred image obtained with a rotating camera tilted to the horizon

This work is a continuation of the authors’ previous publications, in which the restoration of images obtained with a horizontally rotating camera was considered. In this paper, a mathematical model is constructed for reconstructing blurred images obtained with a camera rotating in the horizontal plane and having its optical axis tilted at an angle to the horizon. The method of image restoration involves constructing a strip of spherical panorama from the original images. Results of numerical experiments that confirm the good quality of the presented image recovery method and the high performance of the developed algorithm are presented.

P182 3D TECHNOLOGY IN MINIMALLY INVASIVE UPPER GI SURGERY: COMPARISON BETWEEN DIFFERENT SYSTEMS

Aim Three-dimensional laparoscopy improves the depth of perception during minimally invasive surgery, leading to better visibility and more precise dissection, and providing better clinical and surgical outcomes in complex surgical procedures. The aim of this study was to compare the pros and cons of the 3D technological systems available in our Unit for UGI surgery. Background & Methods In our Unit, we have two different 3D systems for abdominal and thoracic surgery. B Braun has the EinsteinVision 3D system with 0 and 30 degree fixed camera. Olympus produces an Endoeye Flex with an articulating tip 0 degree 3D camera as well as an Endoeye 3D 0 and 30 degree rotating camera. Advantages and disadvantages of the different 3D systems were evaluated on the basis of the experience of our senior surgeons performing routinely 3D operations. Results All surgeons agreed of the superiority of 3D vision compared to conventional 2D laparoscopy or thoracoscopy. The B Braun system is not available in an integrated operating theatre system and does not allow image rotation, but provides a full HD sharp resolution and has the advantage of a reusable camera with single use warming cover which could be used for unlimited procedures every day. The Olympus Endoeye Flex does not provide HD resolution and can be more difficult to manoeuvre, but has the advantage of the articulating tip. The Olympus Endoeye 30 degree rotating camera has a better HD resolution and the advantage of image rotation while maintaining the horizon. Conclusion Technology beyond 3D laparoscopic system has been evolving rapidly. Different products have their own strengths and weaknesses, and surgeons should be familiar with the system used.

3D CAMERAS ACQUISITIONS FOR THE DOCUMENTATION OF CULTURAL HERITAGE

<p><strong>Abstract.</strong> Photography has always been considered as a valid tool to acquire information about reality. Nowadays, its versatility, together with the development of new techniques and technologies, allows to use it in different fields of application. Particularly, in the digitization of built heritage, photography not only enables to understand and document historical and architectural artifacts but also to acquire morphological and geometrical data about them with automated digital photogrammetry. Nowadays, photogrammetry enables many tools to give virtual casts of reality by showing it in the way of point cloud. Although they can have metric reliability and visual quality, traditional instruments &amp;ndash; such as monoscopic cameras &amp;ndash; involve a careful planning of the campaign phase and a long acquisition and processing time. On the contrary, the most recent ones, based on the integration of different sensors and cameras, try to reduce the gap between time and results. The latter include some systems of indoor mapping who, thanks to 360&amp;deg; acquisitions and SLAM technology, reconstruct the original scene in real time in great detail and with a photorealistic rendering. This study is aimed at reporting a research evaluating metric reliability and the level of survey detail with a Matterport Pro2 3D motorized rotating camera, equipped with SLAM technology, whose results have been compared with point clouds obtained by image-based and range-based processes.</p>

High-Efficiency Automatic Recharging Mechanism for Cleaning Robot Using Multi-Sensor

Cleaning robot has the highest penetration rate among the service robots. This paper proposes a high-efficiency mechanism for an intelligent cleaning robot automatically returns to charging in a short time when the power is insufficient. The proposed mechanism initially combines the robot’s own motor encoder with neural network linear regression to calculate the moving distance and rotation angle for the location estimation of the robot itself. At the same time, a self-rotating camera is applied to scan the number of infrared spots on the docking station to find the location of the docking station so that the cleaning robot returns to charging properly in two stages, existing infrared range and extended infrared range. In addition, six-axis acceleration and ultrasound are both applied to deal with the angle error that is caused by collision. Experimental results show that the proposed recharging mechanism significantly improves the efficiency of recharging.

“Bringing the Unseen out of the Shadows”: in Pursuit of Ciné-Trance and Film-Performance in Ben Russell’s the quarry (2002) and TRYPPS #7 (BADLANDS) (2010)

This paper aims to present the ways in which Ben Russell’s films, the quarry and TRYPPS #7 (BADLANDS), tend to draw on conventions traditionally associated with ciné-trance (TRYPPS #7), as developed by Jean Rouch, and film-performance (TRYPPS #7 and the quarry). While both pictures invoke the presence of the sublime, the quarry transforms the featured landscape into an image-object and hence fails to represent the lived experience and instead provides the audience with a spectacle or a sensation simultaneously engaging them in the performance on their own terms. Meanwhile, TRYPPS #7’s reliance on ciné-trance becomes more evident in its attempt to expose the hypnotic and deceptive capabilities of moving-image media, which do not only distort the spectator’s rational sense of space and perspective, but also connote the phenomenon of possession itself through featuring the protagonist’s narcotic trance. To achieve the desired effect, Russell creates an atmosphere of sublimity and transcendence by means of structural and avant-garde film’s devices that transcend the realist–narrative paradigm of anthropological filmmaking, including static and kinetic montage, multiple perspectives, hand-held and rotating camera movements, intimate long takes or fixed shots of extended duration.Article received: December 28, 2017; Article accepted: January 10, 2018; Published online: April 15, 2018; Original scholarly paper How to cite this article: Boczkowska, Kornelia.
