Summary:To provide a learning data collecting device capable of efficiently collecting learning data of a learned model for improving detection accuracy of road obstacles in an image.SOLUTION: For a plurality of frames of images photographed by an on-vehicle camera, which are obtained by detecting a road obstacle in the images using pre-learned learned models and detecting a substance in the images, a learning data collection device outputs, of images between two images in which the road obstacle is detected, an image, in which the road obstacle is not detected and the substance is detected in an area where the road obstacle is presumed to exist, as learning data of the learned model.SELECTED DRAWING: Figure 8 【課題】画像中の路上障害物の検出精度を向上させるための学習済みモデルの学習用データを効率的に収集することができる学習用データ収集装置を得る。【解決手段】学習用データ収集装置は、予め学習された学習済みモデルを用いて画像中の路上障害物を検出し、画像中の物体を検出し、車載カメラにより撮影された複数フレームの画像について、路上障害物が検出された２つの画像の間の画像のうち、路上障害物が存在すると推定されるエリア内に路上障害物が検出されず、かつ物体が検出された画像を、学習済みモデルの学習用データとして出力する。【選択図】図８
