Abstract

A distance measurement system includes: an imaging device including an imaging element where a plurality of imaging pixels are arranged in matrix, and an optical system forming an image of a predetermined region on an imaging surface of the imaging element; and a distance measurer determining a distance to a target object based on data of the image obtained from the imaging element, wherein the optical system includes a free-form surface lens having a rotationally asymmetric shape that forms the image on the imaging surface such that a resolution of a first region in front of the region is higher than that of a second region at a lateral side of the region, each of the resolutions being a ratio of the number of ones of the imaging pixels used to pick up an image included in per unit angle of view to a total number of the imaging pixels.
