Abstract
Provided is a system for localizing a carrier, estimating a posture of the carrier and establishing a map. The system includes: an inertial measurement device, measuring a motion state and a rotation state of the carrier; a vision measurement device disposed on the carrier for picturing an environment feature in an indoor environment where the carrier locates; and a controller receiving measuring results from the inertial measurement device and the vision measurement device to estimate a posture information, a location information and a velocity information of the carrier, and establishing a map having the environment feature. The controller estimates based on a corrected measuring result from one of the inertial measurement device and the vision measurement device, then controls the other one of the inertial measurement device and vision measurement device to measure, and accordingly corrects the posture, location and velocity information of the carrier and the map.
