Abstract : This paper presents image-based navigation from an image memory using a combination of line segments and feature points. The environment is represented by a set of key images, which are acquired during a prior mapping phase that defines the path to be followed during the navigation. The switching of key images is done exploiting the common line segments and feature points between the current acquired image and the nearby key images. Based on the key images and the current image, a control law is derived for computing the rotational velocity of a mobile robot during its visual navigation. Using our approach, real-time navigation has been performed in real indoor environment with a Pioneer 3-DX equipped with an on-board perspective camera and the humanoid robot Pepper without the need of accurate mapping and localization nor of 3D reconstruction. We also show that the combination of points and lines increases the number of features that helps in robust and successful navigation especially in those regions where few points or lines can be detected and tracked/matched.
