Stereo Camera-based Intelligence Surveillance System

Camera Arrangement in Visual 3D Systems using Iso-disparity Model to Enhance Depth Estimation Accuracy

In this paper we address the problem of automatic arrangement of cameras in a 3D system to enhance the performance of depth acquisition procedure. Lacking ground truth or a priori information, a measure of uncertainty is required to assess the quality of reconstruction. The mathematical model of iso-disparity surfaces provides an efficient way to estimate the depth estimation uncertainty which ...

A Smart Camera Mote Architecture for Distributed Intelligent Surveillance

Surveillance is one of the promising applications to which smart camera motes forming a vision-enabled network can add increasing levels of intelligence. We see a high degree of in-node processing in combination with distributed reasoning algorithms as the key enablers for such intelligent surveillance systems. To put these systems into practice still requires a considerable amount of research ...

Removal of Adherent Waterdrops from Images Acquired with a Stereo Camera System

In this paper, we propose a new method that can remove view-disturbing noises from stereo images. One of the thorny problems in outdoor surveillance by a camera is that adherent noises such as waterdrops on the protecting glass surface lens disturb the view from the camera. Therefore, we propose a method for removing adherent noises from stereo images taken with a stereo camera system. Our meth...

Visually Guided Mobile Robots

Our mobile robots use trinocular stereo sensors to sense their environment, navigate around obstacles in a dynamic, unknown world and partner with humans in various tasks. Fundamental to these abilities is the capacity to build a map and locate themselves relative to it, while operating. Here we review a collection of methods that permit mobile robots to acquire spatial and visual maps of their...
