Book excerpt: "High traffic congestion in cities can lead to difficulties in delivering appropriate aid to people in need of emergency services. Developing an autonomous aerial medical evacuation system with the required size to facilitate the need can allow for the mitigation of the constraint. The aerial system must be capable of vertical takeoff and landing to reach highly conjected areas and areas where traditional aircraft cannot access. In general, the most challenging limitation within any proposed solution is the landing sequence. There have been several techniques developed over the years to land aircraft autonomously; however, very little attention has been scoped to operate strictly within highly congested urban-type environments. The goal of this research is to develop a possible solution to achieve autonomous landing based on computer vision-capture systems. For example, by utilizing modern computer vision approaches involving depth estimation through binocular stereo computer vision, a depth map can be developed. If the vision system is mounted to the bottom of an autonomous aerial system, it can represent the area below the aircraft and determine a possible landing zone. In this work, neural networks are used to isolate the ground via the computer vision height map. Then out of the entire visible ground area, a potential landing position can be estimated. An optimization routine is then developed to identify the most optimal landing position within the visible area. The optimization routine identifies the largest identifiable open area near the desired landing location. Web cameras were utilized and processed on a desktop to form a basis for the computer vision system. The algorithms were tested and verified using a simulation effort proving the feasibility of the approach. In addition, the system was tested on a scaled down city scene and was able to determine an optimal landing zone."--Abstract.

Download or read book Autonomous Safe Landing Zone Detection for UAVs Utilizing Machine Learning written by Upesh Nepal and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the main challenges of the integration of unmanned aerial vehicles (UAVs) into today's society is the risk of in-flight failures, such as motor failure, occurring in populated areas that can result in catastrophic accidents. We propose a framework to manage the consequences of an in-flight system failure and to bring down the aircraft safely without causing any serious accident to people, property, and the UAV itself. This can be done in three steps: a) Detecting a failure, b) Finding a safe landing spot, and c) Navigating the UAV to the safe landing spot. In this thesis, we will look at part b. Specifically, we are working to develop an active system that can detect landing sites autonomously without any reliance on UAV resources. To detect a safe landing site, we are using a deep learning algorithm named "You Only Look Once" (YOLO) that runs on a Jetson Xavier NX computing module, which is connected to a camera, for image processing. YOLO is trained using the DOTA dataset and we show that it can detect landing spots and obstacles effectively. Then by avoiding the detected objects, we find a safe landing spot. The effectiveness of this algorithm will be shown first by comprehensive simulations. We also plan to experimentally validate this algorithm by flying a UAV and capturing ground images, and then applying the algorithm in real-time to see if it can effectively detect acceptable landing spots.

This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Computer vision is a growing field in computer science. Since the advancement of Machine learning, Computer vision solutions have been trending. As a result of the growing number of solutions and performance increases in Machine learning, machine learning solutions are now being utilized in the field of robotics. A problem propagates when the evaluation methods that were used previously are used for robotic vision solutions. The accuracy metric although valuable from a data driven perspective lends no benefit to the use in robotics. The accuracy calculated by the performance of the Convolutional neural network on the evaluation dataset is only a relevant metric to the evaluation dataset. The accuracy metric does not define the distance at which the accuracy of the Convolutional Neural Network (CNN) begins to decrease below the required threshold. The accuracy metric does not depict the strengths and weaknesses of the CNN in terms of orientation of the object. The accuracy metric does not show the accuracy of the CNN given a specific orientation and distance. Orientation and distance are factors when considering a computer vision solution for the use in robotics. A popular example is Tesla. Tesla incorporates a multitude of systems in order to produce their self-driving capabilities. One of the systems used is camera feed that utilizes Machine learning to depict the context of the image. Tesla needs their system to perform in a multitude of distance and orientation of objects [9]. Simply using a single accuracy metric will not be enough to define the limitations of the system. What this thesis proposes is an evaluative method capable of defining the spatial limitations of a CNN for 3D objects. This approach utilizes Unmanned aerial vehicle (UAV) mobile sensors in order to generate the desired distances and orientation from the object being evaluated. Multiple flight sequences are conducted to provide information that is able to define the exact point in which the accuracy starts to decrease and the orientations that are the most weak. This approach was tested using a two class CNN that depicted if a Ford Ranger was in the image or if it was not. The experimental results using an Unmanned Aerial Vehicle (UAV) was able to depict the CNN's dependencies such as: the distance from the object, the altitude, the orientation of the object and the impact these dependencies have on accuracy. An UAV was used due to their innate capability as mobile sensors capable of producing any perspective and distance required.
