Abstract(J)レコーダ映像から危険事象など様々な情報が取得できるが、速度記録のないレコーダからの自車速度推定は特に重要である。ただし、推定精度は学習モデルのパラメータ依存であり、パラメータの決定は容易ではない。本報告では3D CNNを用いたレコーダ映像からの自車速度推定におけるパラメータの決定と、推定速度の検討を述べる。

Translation

Abstract(E)Various kinds of information including hazardous event can be obtained on the basis of video saved in dash cams, especially it is important to estimate the automobile speed from the data without recorded speed. However, the accuracy of the estimation results depends on the parameters of the learning model, which parameters cannot be easily determined. Then, this paper reports the decision of the parameters of 3D CNN that are used for the speed estimation on the basis of video, and the discussion about the estimated speeds.

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.
