Abstract
A distance estimating device has a processor configured to calculate first and second right side distances between a moving object and a right side feature and first and second left side distances between the moving object and a left side feature, determine a reference feature-to-feature distance between the right and left side feature at the current location, and estimate a right side and left side distance combination, where the feature-to-feature distance between a right left side feature obtained for each combination of first right side distance corrected by an estimation error or second right side distance and first left side distance corrected by an estimation error or second left side distance, is closest to a reference distance, determining it to be the distance between the moving object and the right side feature and the distance between the moving object and the left side feature, for the current location.
