A distance measurement verification method

Abstract

The invention discloses a verification method for distance measurement. The method includes the following steps: performing initialization; dividing high precision distance sensing units T1, T3, T5 into a first group and T2, T4, T6 into a second group to obtain distances D1, D2 and D3 between the center position and targets, the distances D1, D2 and D3 being a first measurement data group; dividing the high precision distance sensing units T1, T2, T3 into a third group and T4, T5, T6 into a fourth group to obtain distances D4 and D5 between the center position and targets, the distances D4 andD5 being a second measurement data group; obtaining a calculating distance D6 through distance formulas, the calculating distance D6 being a third measurement data group; and judging whether errors can meet presetting threshold values. The method can realize the pre-verification and correction of a distance measurement verification device, and provides verification data for researches and analyses, and therefore, the precision of distance measurement can be effectively improved, the cost is reduced, and the efficiency is enhanced.

Description

technical field [0001] The invention relates to the field of wireless distance measurement, in particular to a distance measurement verification method. 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. [0004] The basis of wireless ranging...
