Book Description
This monograph is devoted to the theory and development of autonomous navigation of mobile robots using computer vision based sensing mechanism. The conventional robot navigation systems, utilizing traditional sensors like ultrasonic, IR, GPS, laser sensors etc., suffer several drawbacks related to either the physical limitations of the sensor or incur high cost. Vision sensing has emerged as a popular alternative where cameras can be used to reduce the overall cost, maintaining high degree of intelligence, flexibility and robustness. This book includes a detailed description of several new approaches for real life vision based autonomous navigation algorithms and SLAM. It presents the concept of how subgoal based goal-driven navigation can be carried out using vision sensing. The development concept of vision based robots for path/line tracking using fuzzy logic is presented, as well as how a low-cost robot can be indigenously developed in the laboratory with microcontroller based sensor systems. The book describes successful implementation of integration of low-cost, external peripherals, with off-the-shelf procured robots. An important highlight of the book is that it presents a detailed, step-by-step sample demonstration of how vision-based navigation modules can be actually implemented in real life, under 32-bit Windows environment. The book also discusses the concept of implementing vision based SLAM employing a two camera based system.

Book Description
The field of robotic vision has advanced dramatically recently with the development of new range sensors. Tremendous progress has been made resulting in significant impact on areas such as robotic navigation, scene/environment understanding, and visual learning. This edited book provides a solid and diversified reference source for some of the most recent important advancements in the field of robotic vision. The book starts with articles that describe new techniques to understand scenes from 2D/3D data such as estimation of planar structures, recognition of multiple objects in the scene using different kinds of features as well as their spatial and semantic relationships, generation of 3D object models, approach to recognize partially occluded objects, etc. Novel techniques are introduced to improve 3D perception accuracy with other sensors such as a gyroscope, positioning accuracy with a visual servoing based alignment strategy for microassembly, and increasing object recognition reliability using related manipulation motion models. For autonomous robot navigation, different vision-based localization and tracking strategies and algorithms are discussed. New approaches using probabilistic analysis for robot navigation, online learning of vision-based robot control, and 3D motion estimation via intensity differences from a monocular camera are described. This collection will be beneficial to graduate students, researchers, and professionals working in the area of robotic vision.

Book Description
A performance analysis of several vision-based robot localization systems is presented for real-time Micro Aerial Vehicle (MAV) navigation tasks in touch-free, GPS denied, and high-accuracy environments. The systems were designed and utilized during our quadrotor visual control research, consisting of a local positioning system (LPS), a simplified monocular visual odometry (VO), and a stereo visual odometry ranging system. Measurement performance is evaluated through experiments performed using a membrane potentiometer sensor as reference. Feature-based image processing algorithms and motion detection methods are implemented to generate 3D position information from 2D image data. Performance analysis gave verified data for the applications of those systems. Final measurement resolution of 1mm was obtained for the LPS, and a high positioning accuracy was demonstrated for the VO systems.

Book Description
"Mobile robotics is an active and exciting sub-field of Computer Science. Its importance is easily witnessed in a variety of undertakings from DARPA's Grand Challenge to NASA's Mars exploration program. The field is relatively young, and still many challenges face roboticists across the boards. One important area of research is localization, which concerns itself with granting a robot the ability to discover and continually update an internal representation of its position. Vision based sensor systems have been investigated, but to much lesser extent than other popular techniques. A custom mobile platform has been constructed on top of which a monocular vision based localization system has been implemented. The rigorous gathering of empirical data across a large group of parameters germane to the problem has led to various findings about monocular vision based localization and the fitness of the custom robot platform. The localization component is based on a probabilistic technique called Monte-Carlo Localization (MCL) that tolerates a variety of different sensors and effectors, and has further proven to be adept at localization in diverse circumstances. Both a motion model and sensor model that drive the particle filter at the algorithm's core have been carefully derived. The sensor model employs a simple correlation process that leverages color histograms and edge detection to filter robot pose estimations via the on board vision. This algorithm relies on image matching to tune position estimates based on a priori knowledge of its environment in the form of a feature library. It is believed that leveraging different computationally inexpensive features can lead to efficient and robust localization with MCL. The central goal of this thesis is to implement and arrive at such a conclusion through the gathering of empirical data. Section 1 presents a brief introduction to mobile robot localization and robot architectures, while section 2 covers MCL itself in more depth. Section 3 elaborates on the localization strategy, modeling and implementation that forms the basis of the trials that are presented toward the end of that section. Section 4 presents a revised implementation that attempts to address shortcomings identified during localization trials. Finally in section 5, conclusions are drawn about the effectiveness of the localization implementation and a path to improved localization with monocular vision is posited"--Abstract.

Book Description
In this chapter, we proposed a vision-based approach to bearing-only SLAM in a 2dimensional space. We assumed the environment contained several visually distinguishable landmarks. This approach is inspired from techniques used in stereo vision and Structure From Motion. Our landmark initialization method relies solely on the bearing measurements from a single camera. This method does not require information from an odometer or a range sensor. All the object positions can be estimated in a landmark-based frame. The trade-off is that this method requires the robot to be able to move in a straight line for a short while to initialize the landmarks. The proposed method is particularly accurate and useful when the robot can guide itself in a straight line by visually locking on static objects. Since the method does not rely on odometry and range information, the induced map is up to a scale factor only. In our method, the distance L1 - L 2 of two landmarks is taken as the measurement unit of the map. The selection of L1 and L 2 is critical for the accuracy of.
