Towards a Real Time Panoramic Depth Sensor

چکیده
Recently we have presented a system for panoramic depth imaging with a single standard camera. One of the problems of such a system is the fact that we cannot generate a stereo pair of images in real time. This paper presents a possible solution to this problem. Based on a new sensor setup simulations were performed to establish the quality of new results in comparison to results obtained with the old sensor setup. The goal of the paper is to reveal whether the new setup can be used for real time capturing of panoramic depth images and consequently for autonomous navigation of a mobile robot in a room.

Multi-Spectral Panoramic Sensor
To reconstruct an environment under 360 degrees with a great accuracy and true color represents an important challenge for motion pictures and multimedia applications. This paper describes a new stereoscopic panoramic sensor to achieve this task. Unlike the existing sensors, it uses four acquisition channels coupled with an additional structured light projector to obtain an accurate 3 0 panoram...

This paper presents a novel 360° High-Dynamic Range (HDR) camera for real-time 3D 360° panoramic computer vision. The camera consists of (1) a pair of bio-inspired dynamic vision line sensors (1024 pixel each) asynchronously generating events at high temporal resolution with on-chip time stamping (1µs resolution), having a high dynamic range and the sparse visual coding of the information, (2) ...
متن کاملA Computer Vision Sensor for Panoramic Depth Perception
A practical way for obtaining depth in computer vision is the use of structured light systems. For panoramic depth reconstruction several images are needed which most likely implies the construction of a sensor with mobile elements. Moreover, misalignments can appear for non-static scenes. Omnidirectional cameras offer a much wider field of view than the perspective ones, capture a panoramic im...

Traditional stereo systems have a small field of view which limits their usefulness for certain applications. By imaging curved mirrors, the field of view of conventional cameras can be enhanced. In this paper, we present the design of a compact panoramic stereo camera which uses parabolic mirrors and is capable of producing 360 panoramic depth maps at the rate of several frames per second. Vid...
متن کاملAcquisition of omnidirectional stereoscopic images and videos of dynamic scenes: a review
Different camera configurations to capture panoramic images and videos are commercially available today. However, capturing omnistereoscopic snapshots and videos of dynamic scenes is still an open problem. Several methods to produce stereoscopic panoramas have been proposed in the last decade, some of which were conceived in the realm of robot navigation and three-dimensional (3D) structure acq...
