Abstract(J)	魚眼ステレオカメラシステム向けに，基準方向における3次元距離測定手法を提案する．本手法では平面面仮定の下で画像拡大率を用いて距離を推定する．数値シミュレーションおよびCGを用いた実験により，入射角が90度に近い場合，従来の視差ベースの測定と比較して精度の向上が得られることが示された． Translation
Abstract(E)	We propose a method for measuring 3D distances in the reference direction for fisheye stereo camera systems. This method estimates distances using image magnification under the assumption of a planar surface. Numerical simulations and experiments using computer graphics demonstrated that, when the angle of incidence is close to 90 degrees, this method achieves higher accuracy compared to conventional parallax-based measurement methods.

About search

How to use the search box

You can enter up to 5 search conditions. The number of search boxes can be increased or decreased with the "+" and "-" buttons on the right.

If you enter multiple words separated by spaces in one search box, the data that "contains all" of the entered words will be searched (AND search).

Example) X (space) Y → "X and Y (including)"

How to use "AND" and "OR" pull-down

If "AND" is specified, the "contains both" data of the phrase entered in the previous and next search boxes will be searched. If you specify "OR", the data that "contains" any of the words entered in the search boxes before and after is searched.

Example) X AND Y → "X and Y (including)" X OR Z → "X or Z (including)"

If AND and OR searches are mixed, OR search has priority.

Example) X AND Y OR Z → X AND (Y OR Z)

If AND search and multiple OR search are mixed, OR search has priority.

Example) W AND X OR Y OR Z → W AND (X OR Y OR Z)

How to use the search filters

Use the "search filters" when you want to narrow down the search results, such as when there are too many search results. If you check each item, the search results will be narrowed down to only the data that includes that item.

The number in "()" after each item is the number of data that includes that item.

Search tips

When searching by author name, enter the first and last name separated by a space, such as "Taro Jidosha".
