The method comprises the steps that a pre-planned test path is displayed on a test plan, manual dotting data of a starting test point are collected by dotting the starting test point of the pre-planned test path on the test plan, and a position sensor outputs synchronous sensor test data of the starting test point, so that data collection of the starting test point is completed; and carrying out data acquisition on the second test point of the pre-planned test path until the data acquisition of all the test points on the pre-planned test path is completed.
After data acquisition of all test points is completed, sensor test data corresponding to a time stamp can be obtained from output data of the position sensor according to the time stamp of each manual dotting data; calculating tangent values of included angles between geometric straight lines determined by adjacent test points according to manual dotting data and sensor test data to obtain a first tangent value sequence and a second tangent value sequence; and calculating the correlation of the first tangent value sequence and the second tangent value sequence to obtain a correlation coefficient.
Specifically, the correlation coefficient ρ (tan θ) is calculated by the following methodS,tanθM)：
(1) Taking time as a base point, and taking Sensor (abbreviated as Sensor) test data and Manual dotting (abbreviated as Manual) data corresponding to the dotting timestamp, wherein coordinate points corresponding to the two data are used as test points to form a synchronous test point sequence:
[XS(t0)，YS(t0)],[XS(t1)，YS(t1)],...,[XS(tN)，YS(tN)]
[XM(t0)，YM(t0)],[XM(t1)，YM(t1)],...,[XM(tN)，YM(tN)]
wherein, [ X ]S(tN)，YS(tN)]Indicating the time stamp t of the test point PN at the manual dottingNCollected manual dotting coordinate data, [ X ]M(tN)，YM(tN)]Indicating that the position sensor is manually doted with a time stamp tNAnd outputting the sensor test coordinate data corresponding to the test point PN at any moment.
The synchronization key sequence can be understood as follows: coordinates of a test point determined by the first manual dotting timestamp as a starting test pointData, i.e. [ X ]S(t0)，YS(t0)]，[XM(t0)，YM(t0)]As coordinate data of the initial test point; setting the test point determined by the second manual time stamp as the coordinate data of the second test point, namely [ XS(t1)，YS(t1)]，[XM(t1)，YM(t1)]As coordinate data of the initial test point; thus, the test point determined by the Nth manual dotting timestamp is the coordinate data of the tail test point, namely [ X [ ]S(tN)，YS(tN)]，[XM(tN)，YM(tN)]As coordinate data of the last test point.
(2) And determining a tangent value sequence of the included angle of the adjacent straight lines according to the synchronous test point sequence.
