New Global Referencing Approach in a Camera-LCD Micro Positioning System

Global positioning system: a new opportunity in physical activity measurement

Accurate measurement of physical activity is a pre-requisite to monitor population physical activity levels and design effective interventions. Global Positioning System (GPS) technology offers potential to improve the measurement of physical activity. This paper 1) reviews the extant literature on the application of GPS to monitor human movement, with a particular emphasis on free-living physi...

Global Positioning System (A Review)

Accurate measurement of physical activity is a pre-requisite to monitor population physical activity levels and design effective interventions. Global Positioning System (GPS) technology offers potential to improve the measurement of physical activity.

A New Nonlinear Distortion Correction Approach for Camera-Projector System

-This paper presents a new approach allowing a projector to display an undistorted image on an unknown geometry surface. In the distortion correction system, a single digital camera is used to capture the viewer’s perspective of the projection surface, and a computer is used to process the origional source image to show an undistortion image from the view position of audience. In the approach, ...

Compensation of Doppler Effect in Direct Acquisition of Global Positioning System using Segmented Zero Padding

Because of the very high chip rate of global positioning system (GPS), P-code acquisition at GPS receiver will be challenging. A variety of methods for increasing the probability of detection and reducing the average time of acquisition have been provided, among which the method of Zero Padding (ZP) is the most essential and the most widely used. The method using the Fast Fourier Transform (FFT...
