Abstract(J)	完全自動運転に向け，低コストで全周囲の認識を実現するため，単眼全周囲ステレオカメラを設計し，初期成果を2019年春に報告した．今回は，超広角に対応したカメラ較正方法と，それを適用した試作機の性能評価を報告する．OpenCVよりも2.2倍高精度な較正により，距離誤差 14 m 8%以下を達成した． Translation
Abstract(E)	We have been developing a monocular omnidirectional stereo camera in order to perceive objects 360-degree around for a low-cost autonomous driving system, which we have reported in the spring 2019. In this talk, we report a new calibration method for the omnidirectional camera and a prototype evaluation applying the method. Our method is 2.2 times more precise than that of OpenCV. The distance error of the prototype is less than 8% for objects 14 meters apart.

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".
