Title:
STEREO DISTANCE MEASUREMENT APPARATUS AND STEREO DISTANCE MEASUREMENT METHOD
Document Type and Number:
WIPO Patent Application WO/2012/011227
Kind Code:
A1
Abstract:
Provided are a stereo distance measurement apparatus and stereo distance measurement method wherein a camera image itself is adjusted to correct a blurring expression, thereby preventing the distance measurement time from being long, while improving the precision of parallax detection. In the stereo distance measurement apparatus (100), a blurring expression adjusting unit (102) uses a blurring expression adjusting filter to tailor the blurring expression of one of a basic image and a reference image, which are to be used by a parallax measuring unit (103), to the blurring expression of the other which is weaker than that of the aforementioned one. In this way, a camera image itself is adjusted, whereby the blurring expression can be corrected. Moreover, tailoring the blurring expression of the one image to the blurring expression of the other image which is weaker than that of the aforementioned one image allows an application of the filter, which is a simple processing, to cause the blurring expressions of the images, which are used in the parallax detection, to coincide with each other. Therefore, the precision of parallax detection can be improved, while the distance measurement can be performed at a high speed.
