The Roll Angle Consistency Constraint
A new method is presented for reasoning with constraints on the three orientation parameters of an object which arise from the identification of features discovered in a single image. The method uses a geometrical model of the object and a tetrahedral representation of view-direction. The final angle parameter, the roll angle, is computed for each view direction. This method is subject to error...
متن کاملEstimation of Vehicle Roll Angle
Haldex Traction can with their Active Yaw Control prevent unwanted handling when driving a vehicle, by applying an extra torque with their all wheel drive system. To be able to calculate when and how this torque should be applied, it is important to the state information of the vehicle. When driving on banked roads, vehicle dynamics and sensor measurements are changed compared to when driving o...
متن کاملOnline Calibration of Camera Roll Angle
Modern day cars are often equipped with a vision system that collects information about the car and its surroundings. Camera calibration is extremely important in order to maintain high accuracy in an automotive safety applications. The cameras are calibrated offline in the factory, however the mounting of the camera may change slowly over time. If the angles of the actual mounting of the camer...
متن کاملParallel Consistency in Constraint Programming
Program parallelization becomes increasingly important when new multi-core architectures provide ways to improve performance. One of the greatest challenges of this development lies in programming parallel applications. Using declarative languages, such as constraint programming, can make the transition to parallelism easier by hiding the parallelization details in a framework. Automatic parall...
متن کاملConstraint Tightness versus Global Consistency
Constraint networks are a simple represen tation and reasoning framework with diverse applications In this paper we present a new property called constraint tightness that can be used for characterizing the di culty of problems formulated as constraint networks Speci cally we show that when the con straints are tight they may require less pre processing in order to guarantee a backtrack free so...
