To segment a range including a part of a vehicle name from an image where an object vehicle appears concerning a technique for recognizing the vehicle name of the object vehicle appearing in the image.SOLUTION: A vehicle name recognition device 100 includes an image segmentation section 132 and a vehicle name estimation section 133. The image segmentation section 132 segments an image of a range satisfying a segmentation condition as an object segmentation image. The segmentation condition is the condition which indicates the range where a position of a license plate detected from the object image where the license plate of the object vehicle appears is defined as reference, and also is the condition which indicates that the image is to be segmented so as to include at least one vehicle part having a feature to be a clue for identifying the vehicle name of the vehicle appearing in the image. The vehicle name estimation section 133 estimates the vehicle name of the object vehicle with the use of data which indicates the object segmentation image and also with the use of an inference model which allows data indicating the image where the range to satisfy the segmentation condition appears to be an input so as to estimate the vehicle name of the vehicle appearing in the image corresponding to the input.SELECTED DRAWING: Figure 1
【課題】画像に映っている対象車両の車名を認識する技術において、対象車両が映っている画像から同様の部位を含む範囲を切り出したい。【解決手段】車名認識装置100は、画像切り出し部132と車名推定部133とを備える。画像切り出し部132は、対象車両のナンバープレートが映っている対象画像から検出したナンバープレートの位置を基準とする範囲を示す条件であって、画像に映っている車両の車名を特定する手掛かりとなる特徴を有する少なくとも1つの車両部位が含まれるように画像を切り出すことを示す条件である切り出し条件を満たす範囲の画像を対象画像から対象切り出し画像として切り出す。車名推定部133は、対象切り出し画像を示すデータと、切り出し条件を満たす範囲が映っている画像を示すデータを入力とし、入力に対応する画像に映っている車両の車名を推定する推論モデルとを用いて、対象車両の車名を推定する。【選択図】図1
