Error modeling in stereo navigation
on scalar models of measurement error in triangulation. Using t h m-dimensional (3D) Gaussian distributions to model triangulation error is shown lo lead lo much better performance. How to compute the error model from image correspondences. estimate robot motion between frames, and update the global positions of the robot and the hndm8rks over time are discussed. Simulations show that, compared...
متن کاملError Modelling in Stereo Navigation
In stereo navigation, a mobile robot estimates its position by tracking landmarks with on-board cameras. Previous systems for stereo navigation have suffered from poor accuracy, in part because they relied on scalar models of measurement error in triangulation. This paper shows that using 3-D gaussian distributions to model triangulation error leads to much better performance. The paper describ...
متن کاملMobile Robot Navigation Error Handling Using an Extended Kalman Filter
Obviously navigation is one of the most complicated issues in mobile robots. Intelligent algorithms are often used for error handling in robot navigation. This Paper deals with the problem of Inertial Measurement Unit (IMU) error handling by using Extended Kalman Filter (EKF) as an Expert Algorithms. Our focus is put on the field of mobile robot navigation in the 2D environments. The main chall...

متن کاملStereo Reconstruction for Visual Navigation
Visual Navigation is the key to enabling useful mobile robots to work autonomously in unmapped dynamic environments. It involves positioning a robot by tracking the world as it moves past a camera. This paper describes techniques we are developing to improve the accuracy of transformations calculated by matching sets of points between two views. This tells us how far the robot has moved. In the...
