Measurement precision analysis system and method of track sensor

The invention relates to a measurement precision analysis system and method for a track sensor, and the system comprises a first calibration platform unit and a control analysis unit, a test point of the first calibration platform unit moves according to a preset test scheme, and generates first data corresponding to the test point; the control analysis unit generates a first track and a second track based on the first data and the second data respectively, and calculates the area of a closed graph or a non-closed graph enclosed based on the first track and the second track and the length of the first track by adopting a one-way distance method; adding the areas of the closed graphs or the non-closed graphs to obtain the total area of the non-overlapped parts, comparing a numerical value obtained by dividing the total area of the non-overlapped parts by the length of the first track with a preset first threshold value, and determining whether the precision of the track sensor meets the precision requirement o
