Abstract(J)夜間遠方認識に必要な教師データ作成は,開発カメラ画像へのアノテーション作業に膨大な工数を要する.本研究では,基線長90cmステレオカメラで~1kmまで検知した結果を,キャリブレーションを基盤とした2段階処理で高精度に開発カメラ画像へ対応付ける自動アノテーション技術を提案し,工数を約90%削減した.

Translation

Abstract(E)Creating training data required for long-range nighttime recognition involves substantial manual annotation work on development-camera images. In this study, we propose an automatic annotation technique that accurately aligns results detected up to approximately 1 km by a 90-cm baseline stereo camera to development-camera images using a calibration-based two-stage processing method, achieving approximately 90% reduction in labor.

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.
