Abstract(J)移動体の自動走行では,高精度な位置推定が要求される.本研究では車速が得られない車両を対象とした,GNSS/IMUのみの位置推定について提案を行う.従来のカルマンフィルタでは非正規分布のノイズにより精度劣化が生じたが,本研究では,加速度誤差を正確に推定することでGNSSマルチパスノイズを低減した位置推定を提案する.

Translation

Abstract(E)For automatic driving of mobile vehicles, highly accurate position estimation is required. In this study, we propose a GNSS/IMU-only position estimation method for vehicles for which vehicle speed is not available. In this study, we propose a position estimation method that reduces GNSS multipath noise by accurately estimating the acceleration error, while the conventional Kalman filter suffers from accuracy degradation due to non-normally distributed noise.

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.
