快速鲁棒的城市场景分段平面重建
Rapid and Robust Piecewise Planar Reconstruction of Urban Scenes
摘要
Abstract
For image-based urban scene reconstruction,traditional pixeMevel or region-level methods often fail to achieve satisfactory results because of various negative factors such as illumination variations,perspective distortion,poorly textured regions,etc.To address this problem,a rapid and robust piecewise planar stereo method is proposed in this paper.Under the scene piecewise planar assumption and by taking into account the structural characteristics of urban scenes,the proposed method at first extracts sufficient and reliable candidate planes from initial spatial points based on the connected-region detection;then the problem of scene reconstruction is converted into a plane labeling problem under the Markov random field (MRF) framework.By virtue of the high reliability of our extracted candidate planes and the energy model properly designed by incorporating geometric constraints,spatial visibility and photo-consistency measures,a complete scene structure is effectively reconstructed.Experiment results show that the proposed method can satisfactorily handle the low-reliability and incomplete-reconstruction problems in traditional methods with computational efficiency.关键词
