Abstract
The method includes: determining a reference sensor from at least two sensors and sampling moments of the reference sensor; when obtaining observation data of a sensor K at a moment t, determining a type of the sensor K; if the sensor K is a first sensor of a first type, determining a sampling moment Tthat is closest to tand an interpolation coefficient λ, and calculating first rotation data and first translation data that are at T, and a first covariance matrix; if the sensor K is a second sensor of a second type, determining two sampling moments Tand Tthat are closest to tand interpolation coefficients λand λ, and calculating second rotation data and second translation data that are of the second sensor from Tto T, and a second covariance matrix; merging rotation data, translation data, and covariance matrices that are at the sampling moments.
