Slanted Stixels: A Way to Represent Steep Streets

Daniel Hernandez-Juarez, Lukas Schneider, Pau Cebrian, Antonio Espinosa, David Vazquez, Antonio M. López, Uwe Franke, Marc Pollefeys, Juan C. Moure
2019 International Journal of Computer Vision  
Our approach overcomes the previous rather restrictive geometric assumptions for Stixels by introducing a novel depth model to account for non-flat roads and slanted objects.  ...  Both semantic and depth cues are used jointly to infer the scene representation in a sound global energy minimization formulation.  ...  Fig. 2 2 Fig. 2 Scene representation obtained by our method of a challenging street environment with a slanted road.  ...

Curb reconstruction using Conditional Random Fields

Jan Siegemund, David Pfeiffer, Uwe Franke, Wolfgang Forstner
2010 2010 IEEE Intelligent Vehicles Symposium  
Based on a 3D point cloud, we estimate the parameters of a 3D curb model, incorporating also the curb adjacent surfaces, e.g. street and sidewalk. We apply an iterative two step approach.  ...  ., obtained from dense stereo vision, are assigned to the curb adjacent surfaces using loopy belief propagation on a Conditional Random Field.  ...  Approaches modeling the car's free driving space, as for example the Stixel World representation by Badino et al.  ...

Performance Metrics and Test Data Generation for Depth Estimation Algorithms

Katrin Honauer
2019
To develop and select suitable and safe algorithms, it is essential to gain a thorough understanding of their respective strengths and weaknesses.  ...  Stereo and light field algorithms take structured camera images as input to reconstruct a depth map of the depicted scene.  ...  For situations like the person lying on the ground (see third row), slanted cardboards or a Stixel representation [2] are required.  ...
