Distance measuring apparatus, distance measuring method, and program

摘要

Disclosed are a distance measuring apparatus which can measure the distance to an object with high accuracy, a distance measuring method, and a program. The distance measuring apparatus is provided with: a light source which emits light; an image pickup unit, which picks up an image of light which has been emitted from the light source and reflected by means of the object; an image distance data converting unit, which converts image data obtained by the image pickup performed by the image pickup unit into image distance data which indicates the distance to the object; an image pickup condition setting unit, which sets first image pickup conditions on the basis of the image distance data; and an image pickup control unit, which controls the light source and the image pickup unit and have an image of the object picked up under the first image pickup conditions.

主权项

1. A distance measuring apparatus comprising:
a light source for emitting light; an image capturing unit for capturing an image of a subject based on the light emitted from the light source and reflected from the subject; a distance information converter for converting pixel values of pixels which are obtained by the image capturing unit when the image capturing unit captures the image of the subject, into distance information representing a distance up to the subject; an image capturing condition setting section for setting first image capturing conditions based on the distance information; an image capture controller for controlling the light source and the image capturing unit to capture the image of the subject under the first image capturing conditions; and a distance measurement accuracy analyzer for analyzing a distance measurement accuracy under the first image capturing conditions and identifying an accuracy lowering distance at which the distance measurement accuracy is worse than a certain value; wherein the image capturing unit comprises a two-dimensional matrix of pixels; and the distance information converter converts each of pixel values of the pixels which are generated when the image capturing unit captures the image of the subject, into distance information to obtain one image distance data.
