Abstract(J)4Dイメージングレーダは耐環境性や遠距離認識に優れる一方,点群がノイズを多く含み疎であるため,物体検出や自己位置推定などへのタスクへの応用には課題が残る.本研究では点群のみから汎用的な特徴を抽出するため,穴埋め問題を用いた自己教師あり事前学習モデルを構築し,物体検出で有効性を評価する.

Translation

Abstract(E)4D imaging radars excel in environmental robustness and long-range detection. However, their point clouds contain abundant noise and are sparse, making challenges for tasks such as object detection and self-localization. In this study, we build a self-supervised pre-training model based on a masked reconstruction task to extract generalizable features from radar point clouds, and evaluate its effectiveness in object detection.

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.
