讲座内容简介:

Coverage is a key issue for visual sensor networks for industrial inspection, environmental monitoring and surveillance, etc., however, it is still challenging due to the anisotropic field sensing rather point sensing, 3-D sensing of 3-D objects, and high complexity for optimization. In this talk, we will present a visual distance approach for multi-camera deployment through parallel coverage optimization over three-dimensional (3-D) space to inspect 3-D objects. The key idea is the proposal of a new `visual distance' between a single camera and a scene point, which takes into account multiple coverage criteria. It is shown that this new measure is capable of characterizing the coverage level of a task point in a quantitative way. Based on the visual distance, a coverage strength model and a new type of scene partition, called ‘Visual Voronoi Partition’ (VVP), are established, and then a parallel gradient optimization approach is developed to achieve optimal coverage performance of a multi-camera network. Comparative simulation and experimental results are provided to show the effectiveness and superior performance of the proposed approach.
