    On Autonomous Driving: Combining Holistic and Feature based Localization Systems (Reasons and Advantages)

    $15.00

    Abstract: This paper highlights the importance of combining intensity and feature based localization systems in autonomous driving. The intensity based localization system is represented by calculating cross correlation between LIDAR and map images. The feature based system is integrated by extracting the lateral edges from the LIDAR and map images with respect to the heading angle. An edge matching technique is then applied to estimate the lateral position based on the common extracted features. The experimental results have verified that the estimation of the lateral and longitudinal positions has been improved against the changes of weather and environmental conditions by combining the image and edge matching results.

    Development of Inshore Fishing UAV at Sea Based on Preliminary Assessment Result

    $15.00

    Abstract: This paper initiates and describes the development of an inshore fishing UAV at the seashore, where the UAV can communicate with its controller by sending all the information during its flight in real time to the base station. The operation distance of the UAV from the seashore is to the fishing point will be between 500 m to 1km. The navigation method is under investigation, which is to guide the UAV from the seashore to fishing points along a predefined path planning by avoiding sudden obstacles it may face.

    Integration of Drone’ Communication into an ITS Network

    $15.00

    Abstract: This paper presents the concept of a highly-sophisticated network system using unmanned aerial vehicles, further named drones, and wireless networks for enhancing safety against natural disasters. The system consists of several drones and ground vehicles. Each vehicle has a wireless network unit, which employs the dual-mode Wireless Access in Vehicular Environment (WAVE) in the 700 MHz or 5 GHz band, with the goal of creating a multi-hop (more than three hops) ad hoc network. These features enable the system to facilitate rescue and relief operations in the event of a serious disaster. The proposed system represents an innovation in the field of mesh network systems, being based on a combination of ubiquitous drones and ground vehicles.

    LIDAR-based Object Classification for Autonomous Driving on Urban Roads

    $15.00

    Abstract: Object classification is an important technique for autonomous vehicles to identify surrounding dynamic objects and execute safe path planning. In this paper, a multi-class object classification method is proposed to classify objects around the vehicle into car, pedestrian bicyclist, and background using a LIDAR sensor. The various effective features of each object are computed using 3D point clouds, and Real AdaBoost algorithm is applied for multi-class classification. In addition, class probabilities are calculated and updated in a time series framework for tracking objects. Classification is evaluated using a dataset that includes long-range objects over 50m. The overall accuracy of the clusters for each frame is 92.7% and for tracking objects is 95.5%. Moreover, processing time for object classification is 0.07ms. Thus, this method can be used in real time for autonomous driving on urban roads.

    Rapid Human Body Detection in Disaster Sites using Image Processing from Unmanned Aerial Vehicle (UAV) Cameras

    $15.00

    Abstract: The development and impact of technology on our everyday lives cannot be compared with the world our ancestors lived in several decades ago. This is described as the world of technology (WoT). But despite all the advancements in technologies, understanding of the mechanisms of nature and the damages caused via natural disasters, such as earthquakes, landslides, and flooding to mention only a few, are still very far away. In the effort of saving lives during natural disasters, such as earthquakes, this study introduces a rapid human body detection technology using image processing from UAV camera. The skin color from a female student is first extracted in RGB then converted to HSV. Next, opening and closing morphological operations are performed eight times each to remove all noise present in the image. Experimental tests were performed both indoor and outdoor, where the female student presented an object close and far to the camera to check the detection capability in both cases. The experiment results show that close or far, the camera can clearly detect both a human body and any part of a human body. The results of the experiment proves the merit of the proposed method.

    Convolutional Neural Network Based Vehicle Turn Signal Recognition

    $15.00

    Abstract: Automated driving is an emerging technology in which a car performs the tasks of recognition, decision making, and control. Recognizing surrounding vehicles is vital in generating the trajectory of an ego-vehicle. This paper focuses on detecting a turn signal information as one of the driver’s intention for surrounding vehicles. This information helps to predict the driver’s behavior in advance especially as instances of lane change and turns at an intersection. Using their intension, the automated vehicle is able to generate a safety trajectory before the driver’s behavior changes. The proposed method recognizes the turn signal of the target vehicle using a mono-camera. It detects the lighting state using Convolutional Neural Network, and then calculates a flashing frequency using Fast Fourier Transform.

    Preliminary Assessment for Inshore Fishing UAV (ISFUAV)

    $15.00

    Abstract: The development and entry into service of unmanned air vehicle (UAV) systems has a long, history. Unfortunately, the vision of engineers and scientist is have seldom matched that of administrators, regulators or financiers. The availability of UAV systems has also often depended upon the maturation of the requisite technology. UAV systems are now being operated by several military forces and currently, to a more limited extent, by civilian organizations. Civilan organizations, however, may eventually expand to exceed, in number and diversity, those of the military [1]. UAV are now use in many domains to perform tasks that may cause risk to human life or in the surveillance of the suicide sites to prevent young people in depression to from committing suicide. UAV are also used to collect information to support decision making during crises, in monitoring disasters sites, for assisting rescue teams during the rescue operations and the list goes on. Given the capability of UAV to perform many civilian tasks to contribute to a sustainable society, this paper assesses what is needed to move the UAV to the fishing industry in order to develop the Inshore Fishing Unmanned Aerial vehicle (ISFUAV). The assessment consists of how to combine real fishing materials, their fishing material weight in relation to the ISFUAV, and the system capable of carrying those fishing materials to the fishing area into the sea and depth zone fishing.

    Verification Experiment for Drone Charging Station Using RTK-GPS

    $15.00

    Abstract: In recent years, Drone’s research has become popular, and there is a need to automate the cycle of takeoff, flight, landing, and charging of Drone. Mainly, the problem remains in automatic battery charging. Therefore, in this research, we will realize Drone’s charging station using RTK-GPS with high accuracy. We verified the landing accuracy by experiment. From the results of the verification, it was found that relative positional error between drone and the charging station can be eliminated by referring to the same reference position. Thus, the possibility of navigating Drone to the charging station can be easily implemented.
