Abstract

The invention discloses a dynamic three-dimensional speed measurement system and method based on a UWB technology. The system comprises a positioning base station, a positioning label and a speed calculation system. Through high-frequency refreshing, distance measurement and unified time service, the real-time speeds of a moving target in three dimensions in a moving process are given; the speedsof the moving target in different time periods can be given according to different time granularities; and engineering application and experimental measurement are better facilitated, particularly forthe moving target of which the speed changes drastically and moves at a high speed. By means of the high-precision distance measurement characteristic of the UWB, base stations and labels are flexibly deployed according to different experiment speed measurement scenes, the real-time speed of the moving target is measured, and application scenes are not affected by indoor and outdoor scenes and weather.

Description

technical field [0001] The invention relates to three-dimensional velocity measurement technology, in particular to a dynamic three-dimensional velocity measurement system and method based on UWB technology. Background technique [0002] With the rapid development of electronic technology and semiconductor technology, MEMS sensing technology has been greatly developed. With the continuous updating of sensor technology, similar vibration and acceleration sensors have been widely used in daily life. Acceleration and angular velocity sensors can only measure moving objects Instantaneous angular velocity and angular velocity, while real-time speed measurement, especially dynamic speed measurement is still a difficult problem in industrial processing and flight experiments. [0003] At present, a group of high-speed cameras are mainly used to capture images of moving objects in different dimensions, and then image analysis is used to measure the three-dimensional speed of moving ...
