The scene map building is the key of robot navigation. This paper proposes the principle of projection of virtual height line (PVHL) and its application in the scene map building. At first partition the scene scope uniformly into grids. Then introduce virtual height lines (VHLs) which do not exist in the scene. Each VHL is projected into left image and right image, and two projection lines are generated...
This paper presents a new, computationally inexpensive, terrain roughness assessment technique. The technique, targeted for high speed unmanned ground vehicles (UGVs), considers no previous knowledge about the terrain but a priori knowledge about the vehicle's characteristics such as damping ratio, natural frequency and wheel configuration. The approach aims to allow fast, smooth and safe transition...
Binocular Stereo vision system has been actively used for real time obstacle avoidance in autonomous mobile robotics for the last century. The computation of free space is one of the essential tasks in this field. This paper describes algorithm for obstacle avoidance for mobile robots which can navigate through obstacle. While most of the paper based on stereo vision works on the disparity image but...
Autonomous robot navigation has many applications such as space exploration and autonomous vehicles. Currently, such navigation is ensured by the use of multiple sensors which may hinder quick commercialization. In this article, we propose a solution for navigating a robot in an unknown environment using only monocular vision algorithms.
Recently, many vision-based navigation methods have been introduced as an intelligent robot application. However, many of these methods mainly focus on finding an image in the database corresponding to a query image. Thus, if the environment changes, for example, objects moving in the environment, a robot is unlikely to find consistent corresponding points with one of the database images. To handle...
