Most of the landslide and flood prediction models require the Digital elevation Model (DEM) as the input. DEM is the digital representation of topographic and manmade features located on the surface of the earth. DEM also needed in hydrologic analyses, resource management and environmental assessment and including interferometry synthetic aperture radar (InSAR) applications. The increased use of DEM...
The author has introduced a generic method for photogrammetric survey using a multi-rotor unmanned aerial vehicle (UAV) for mapping a simulated model and slope area. The objective of this study is to assess the capabilities of UAV for slope mapping. This study only concentrates on multi-rotor UAV, which is known as Hexacopter. Several ground control points (GCP) and checked point (CP) were established...
Emerging Camera Sensor Networks (CSN) leverage the collaboration, processing and communication capabilities of modern cameras to handle a wide variety of security and safety-critical tasks, including target tracking. However, the performance of CSN in terms of tracking accuracy can be severely degraded when faults occur. Faults may be caused by unpredictable software errors (e.g., in the image processing,...
Recently, some commercial software to generate digital surface model (DSM) were provided from some vender. One software is based on the bundle method using conventional Photogrammetry, another one is based on structure-from-motion method (SfM) under computer graphics technology. It is wavered to choose which software to generate DSM derived from drones. In this work, the accuracies of DSM were verified...
People often need help when filling out paper forms, because they do not fully understand the meaning of form fields. Commonly adopted solutions are referring to the form filling instructions or consulting other people. However, they are either inefficient or inconvenient. In this paper, we propose a situation-aware and interactive system, named Interact Form, to help people fill out paper forms....
This paper discusses the design and implementation of a light-weight thermal camera payload for small fixed-wing UAVs with a pan/tilt mechanism and georeferencing based on a simple autopilot's GPS and IMU. Further, an effective and simple method to accurately calibrate a thermal camera is developed and tested. In order to evaluate the accuracy of the georeferencing algorithm, a test flight was conducted...
This paper presents the results of the validation of a prototype vision measurement system for use in experiments on civil engineering structures. The system is tested against a uni-axial earthquake shake table designed to hold full-size masonry walls. We compare the reference earthquake signal, the forcing signal, and the observed signal in terms of displacement with time.
This paper has discuss the image processing of aerial photograph acquired from unmanned aerial imagery capturing system (UAiCs) in generating a digital orthophoto and digital elevation model of a small catchment. The purpose of the study is to produce a recent digital elevation model of the study area which comprise of terrain and water bodies particularly in depicting river water level during rainy...
A technique was developed by which seafloor images gathered by a hovering AUV can be mosaicked based on the vehicle position at each image. In the first phase of development, software was produced to interpret the AUV logs and output parametric files for each image. The images and their parameters are then assembled into a mosaic using GIS software. The improvements to the overall chain of mosaic...
The surveying technique of close-range Photogrammetry is based on an approach of representation of the image forming mechanism of photography and extract spatial information through computation on photos. This research used the fundamentals of close-range Photogrammetry and is applied to model leaves, measure the geometric model of leaf length and width and compare with the conventional measurement...
Vehicle classification is a vital measure used to ensure appropriate roadway design as it affects both capacity and pavement endurance. Given that, departments of transportation across the US collect vehicle miles travelled (VMT) for their highways using automatic vehicle classifiers (AVC), and then use these figures for future highway design. Accuracy assessment of AVCs is thus important to ensure...
The correct leg length and the position of the hip rotation center are the most important parameters for hip implant surgery. Until now there exist no suitable methods to measure it objectively. This paper describes an approach for determining leg length and hip rotation center with an optical measurement system for total hip replacement procedures. A software was programmed by the authors for this...
TV Service using a mobile device as a second screen has been increasing. We propose a new TV system which is able to augment representation of TV programs beyond the TV screen. In the system, which we named augmented TV, since animated 3DCG content interlocked with TV programs is overlaid on live video from the mobile device camera in the mobile device screen by augmented reality techniques, the representation...
In today's world of digitization time complexity, high accuracy and user friendly interfaces are key issues of any successful software system. A digitized image of any data or model drawn on paper is always useful in terms of content retrieval and analysis. This paper presents a new approach for circuit simulation named as Image based Circuit Simulation (ICS). ICS is a technique to convert sketched...
It is intended to develop a high-precision binocular eye tracking system to assess the eye behavior whilst watching stereo 3D content. Up to now, available eye tracking systems are not providing necessary high precision for issues concerning stereo 3D perception. Hence, an up to now not available detailed specification of the recordings of the eye movements as well as the interpretation of binocular...
The demand for aquaculture tools have been increasing due to the rising needs for fish. Several factors show the potential requirements for software solutions. For instance, the continual market value growth of fish, government focus on innovative technologies and research on increasing fish production. The Aquatic Tool Kit aims to calculate the total number of larval and juvenile fish through image...
An exertainment support system called Remote Kenken is proposed in this paper. The game resembles hopscotch. Pressure sensors are used to determine the position of the feet of a player and judge the accuracy of the steps during jumping. Victory or defeat is decided by the accuracy of the step and time required. The support system is networked to a server to allow the game to be played remotely by...
The principle of the passive optoelectronic rangefinder (POERF) is known since c. the second half of 1950s. Publications about research and development of POERF do not exist practically. Presumptive causes are presented in this contribution. We deal with POERF research and development since year 2003. The last fully functional demonstration model is from the year 2009. We present firstly its brief...
During development of the passive optoelectronic rangefinder (POERF), its simulation model enacts an important role. The key part of algorithm for a range measurement by POERF is the disparity estimation of images T'1 and T'2 of a target point T from the stereo pair images. Specific conditions of this task do not allow using commonly published algorithms for the solution of stereo-correspondence problem...
As a new photogrammetry sensor, ADS40 still has no large-scale applications in our country. The low automatic degree and security classification are the main problems when handling data on the local coordinate system in the current production process. The automatic post-process method is put forward, which can remarkably simplify the data process flow, improve the data production efficiency and enhance...
