An ID and Position Recognition Method Employing Camera Motion Blur for Modulated LED Tube Lights
In this paper, we present an image-based 3D positioning method by using produced motion blur for a novel camera-based indoor navigation system. This system, avoiding adopting any expensive equipment, could provide exact 3D location and orientation for mobile users. High-intensity LED tube, which is expected to be the next generation of illumination source, is used as optical marker in this syst...
متن کاملDistributed Smart Camera Calibration Using Blinking LED
Smart camera networks are very powerful for various computer vision applications. As a preliminary step in the application, every camera in the scene needs to be calibrated. For most of the calibration algorithms, image point correspondences are needed. Therefore, easy to detect objects can be used like LEDs. Unfortunately, existing LED based calibration methods are highly sensitive to lighting...
متن کاملDistance Estimation of Smart Device using Bluetooth
Distance estimation identifies the distance between two machines in wireless network. The Received Signal Strength Indication (RSSI) of Bluetooth can be used to estimate distance between smart devices. The characteristic of Bluetooth RSSI value is different as environments. So, we have tested the relation between distance and Bluetooth RSSI value in several environments, such as indoor hall, me...
متن کاملThree dimensional distance measurement based on single digital camera
This paper proposes a 3D space distance measuring method to accomplish non-contact 3D space distance measuring by using a digital camera or digital video camera. The measuring principle of the proposed method in this paper is to learn the present camera shooting distance and the horizontal or vertical distance between the given points according to the number of pixels of the image in horizontal...
متن کاملA Mobile and Fog-based Computing Method to Execute Smart Device Applications in a Secure Environment
With the rapid growth of smart device and Internet of things applications, the volume of communication and data in networks have increased. Due to the network lag and massive demands, centralized and traditional cloud computing architecture are not accountable to the high users' demands and not proper for execution of delay-sensitive and real time applications. To resolve these challenges, we p...
