Guardrail stand column burial depth detection and correction method
The invention discloses a method for detecting and correcting the burial depth of a guardrail stand column. The method comprises: measuring the burial depth actual values Lri (i = 1-n) of a pluralityof groups of guardrail stand columns with burial depth grades; detecting the burial depth of each stand column by using a guardrail stand column burial depth detection device to obtain a burial depthdetection value Lci; and obtaining an error [epsilon]i according to the burial depth actual value Lri and the burial depth detection value Lci of the stand column, forming an error set of [epsilon]1,[epsilon]2,..., [epsilon]n according to n error results, obtaining a correction value Li of the ith burial depth detection value Lci according to a reference formula defined in the specification, andobtaining a current confidence interval according to a formula defined in the specification, wherein [epsilon]<-> is the average error value between the burial depth actual value Li of the stand column and the burial depth detection value Lci, Z[alpha]/2 is a single-side interval value of normal distribution with unilateral confidence of (1-[alpha]/2), and S[epsilon] is a root mean square value ofan error between the burial depth actual value Lri and the burial depth detection value Lci of the stand column. According to the invention, the method can improve the burial depth detection precision of a conventional guardrail column, and can give a confidence interval under a certain confidence degree.
本发明公开了一种护栏立柱埋深检测修正方法。首先量得多组埋深档次的多根护栏立柱的埋深实际值Lri(i＝1～n)，再利用护栏立柱埋深检测装置对每根立柱的埋深进行检测得埋深检测值Lci，由立柱的埋深实际值Lri与埋深检测值Lci可得误差εi，则由n个误差结果可组成误差集：ε1，ε2，...，εn，参照式可得第i个埋深检测值Lci的修正值Li，根据得到当前置信区间。其中，为立柱的埋深实际值Li与埋深检测值Lci之间的平均误差值；为单侧置信度为的正态分布的单侧区间值；Sε为立柱的埋深实际值Lri与埋深检测值Lci之间误差的均方根值。与现有技术相比，本发明的有益效果是：可提高现有护栏立柱埋深检测精度，能够给出在某一置信度下的置信区间。
