Abstract :
A feature-based technique is presented for 3D motion and structure estimation of rigid objects from a sequence of images. Considered is a feature-based rigid object representation which is more complete as compared to previous techniques. In this approach the features provide information regarding the location and type of significant object components and connections. A robust enhanced Hough transform (HT) approach is proposed for line and junction detection. Based on a perspective projection imaging model the extracted feature points of an object are for estimating its 3D motion and structure parameters by means of the unscented Kalman filter (UKF). The performances of the HT-based feature extractor and the UKF are illustrated via simulation results.
