A distance measurement verification method based on wireless ranging

Abstract

The invention discloses a distance measurement and verification method based on wireless ranging. The method includes steps of initializing, classifying high-precision distance sensing units T1, T3 and T5 as a first group, T2, T4 and T6 as a second group; using the distances D1, D2 and D3 from the center position to the target as the first group of measurement data; classifying high-precision distance sensing units T1, T2 and T3 as a third group, and T4, T5 and T6 as a fourth group, and acquiring distances D4 and D5 from the center position to the target as the second group of measurement data; after moving, respectively acquiring distances D7, D8, D9, D10, D11 from the center position to the target; through the distance formula, acquiring the calculation distance D6, and others. The device and method can verify and amend the ranging verification device in advance and provides verification data for study and analysis, and thereby effectively improving the ranging precision, reducing cost, and improving efficiency.

Description

technical field [0001] The invention relates to the field of wireless distance measurement, in particular to a distance measurement verification method based on wireless distance measurement. Background technique [0002] At present, there are many ways of wireless ranging, and each ranging method has its own advantages. However, in a complex and changeable environment, different ranging methods will be affected by various factors, reducing the distance measurement. Accuracy, especially for some situations that require precise distance measurement, it is becoming more and more important to achieve high-precision distance measurement. [0003] Wireless ranging technology is the basis for practical applications such as wireless positioning and navigation. If the distance can be accurately measured, then high-precision positioning and navigation can be achieved. Therefore, it has received more and more attention from many industries. Demand spans across many industry sectors. ...
