Development of Wind Observation System Utilizing Inertial Single Photogrammetry

Abstract

The objectives of the study are to develop a system to measure the data of wind flow in both the horizontal and vertical directions utilizing inertial single photogrammetry, and to establish the methodology for three dimensional measurement on site of wind flow near the ground surface.
This system uses a one digital camera set on the ground, which photograph balloon released as a tracer, thereby three-dimensionally analyzing the balloon's path of particle.
The paper first describes the fabrication of an analytical method, followed by experiments carried out using the method. The experiments consisted of a provision and utility experiment. The provision experiment consisted of a measurement of the three-dimensional position of ball suspended in a laboratory with a single photograph of the ball being used. The utility experiments measured the paths of particles of wind flowing on the schoolyard.
The results of the experiments proved that the fabricated analytical method was effective.
