Abstract(J)	衝突中のトーボードの変形計測手法を提案する。車両内ステレオカメラによる計測は衝突の振動影響を受けるため、ジャイロセンサと追加のカメラにより測定したステレオカメラの姿勢・位置を補正に使用することで、トーボードのグローバル座標系における変形計測結果を得る。実際の衝突試験に適用し、有効性が確認された。 Translation
Abstract(E)	This paper presents a technique to measure and position a toe board during car crash tests. The three-dimensional deformation of the toe board marked with dots is measured using stereovision. As the stereovision fixed to the car vibrates in a crash, observed deformation includes motions of the stereovision itself. By mounting the stereovision on a sensor suite that contains gyros and a camera facing downward, the suite measures the position of the stereovision with respect to the global frame and allows the positioning of the toe board. The effectiveness of the proposed technique was validated in the actual car crash test.

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".
