By a News Reporter-Staff News Editor at Journal of Transportation -- DENSO CORPORATION (Kariya, Aichi-pref., JP) has been issued patent number 9317940, according to news reporting originating out of Alexandria, Virginia, by VerticalNews editors.
The patent's inventors are Kawasaki, Naoki (Kariya, JP); Imanishi, Masayuki (Okazaki, JP); Suzuki, Shunsuke (Nukata-gun, JP); Takafuji, Tetsuya (Anjo, JP).
This patent was filed on April 23, 2013 and was published online on April 19, 2016.
From the background information supplied by the inventors, news correspondents obtained the following quote: "A cruising zone division line recognition apparatus that recognizes a cruising zone division line (such as a white line) on a road is known. The cruising zone division line recognition apparatus acquires an image of a vehicle periphery from an on-board camera. The cruising zone division line recognition apparatus then uses an image recognition technique to recognize a cruising zone division line from the image. The recognized cruising zone division line can be used by a driving assistance system, such as a vehicle lane deviation warning system or a lane keep assist system. An intermittent double line is a type of cruising zone division line. To stably recognize the intermittent double line, a technology is proposed in which pattern determination is performed (refer to PTL 1)."
Supplementing the background information on this patent, VerticalNews reporters also obtained the inventors' summary information for this patent: "Technical Problem
"When the cruising zone division line is, for example, the intermittent double line (10-1 and 10-2) shown in FIG. 11, the following problem occurs when the cruising zone division line recognition apparatus attempts to recognize the intermittent double line. In other words, when the cruising zone division line recognition apparatus attempts to recognize the intermittent double line (10-1 and 10-2), for example, as shown in FIG. 11, the intermittent line (10-1) on the inner side and the intermittent line (10-2) on the outer side are both recognition subjects. Therefore, the recognition result is a discontinuous, disjointed line 20 indicated by shaded rectangles in FIG. 11. When driving assistance is performed using a recognition result such as this, driving may be hindered. The present invention has been achieved in light of such issues. An object of the present invention is to provide a cruising zone division line recognition apparatus that is capable of solving the above-described problem.
"Solution to Problem
"To solve the above-described problem, the present application provides, as a typical example, a cruising zone division line recognition apparatus that includes: an image acquisition device that acquires an image including a road surface ahead of a vehicle; and an image processing device that has an image processing function for adding blurring to an area including the road surface in the image acquired by the image acquisition apparatus, and a cruising zone division line recognition function for recognizing a cruising zone division line from the image to which blurring has been added.
"The cruising zone division line recognition apparatus of the typical example recognizes the cruising zone division line using an image after blurring has been added. In the image after blurring has been added, even when the cruising zone division line is an intermittent double line, the overall cruising zone division line is a single thick line. Therefore, the recognized cruising zone division line does not become a discontinuous, disjointed line."
