DISTANCE MEASUREMENT APPARATUS, IMAGING APPARATUS, DISTANCE MEASUREMENT METHOD, AND PROGRAM

摘要

A distance measurement apparatus that calculates distance information based on a first and second images, including: a first calculation unit that calculates, for each pixel for distance calculation, distance information on the pixel on the basis of a local area in the first image including the pixel and a local area in the second image corresponding to the local area in the first image; a second calculation unit that calculates a non-similarity between the local area in the first image and the local area in the second image; a determination unit that determines whether the non-similarity is higher than a threshold; and a third calculation unit that calculates a ratio of the number of local areas for which the non-similarity is determined to be higher than the threshold in a predetermined area to the number of local areas in the predetermined area.

主权项

1. A distance measurement apparatus that calculates distance information based at least on a first image and a second image,
the distance measurement apparatus comprising: a first calculation unit configured to calculate, for each pixel for distance calculation, distance information on the pixel on the basis of a local area in the first image including the pixel and a local area in the second image corresponding to the local area in the first image; a second calculation unit configured to calculate a non-similarity between the local area in the first image and the local area in the second image; a determination unit configured to determine whether the non-similarity is equal to or higher than a threshold; and a third calculation unit configured to calculate a ratio of the number of local areas for which the non-similarity is determined to be equal to or higher than the threshold in a predetermined area to the number of local areas in the predetermined area.
