Abstract

Provided is a stereo distance measurement apparatus wherein a camera image itself is adjusted to correct the blur, thereby preventing the distance measurement time from being long, while improving the precision of disparity detection. In the apparatus (), a blur adjusting unit () uses a filter to tailor the blur of one of two images used by a disparity measuring unit (), to the blur of the other which is weaker. A camera image itself is adjusted, whereby the blur can be corrected. Moreover, tailoring the blur of the one image to the blur of the other image which is weaker allows an application of the filter, which is a simple processing, to cause the blurs of the images used in the disparity detection, to coincide with each other. Therefore, the precision of disparity detection can be improved, while the distance measurement can be performed at a high speed.
