Zusammenfassung: | PROBLEM TO BE SOLVED: To make it possible to properly call attention in accordance with a visual ability of an individual driver.SOLUTION: A retina projection image estimation unit 12 is configured to estimate a retinal projection image serving as a picture image of an outside world to be projected onto the retina of a driver on the basis of an outside world image, a direction of a driver's visual line, and an eye characteristic of an individual. A retina output image estimation unit 13 is configured to, when the retina projection image is projected onto a retina visual cell array model, estimate a retinal output image serving as a picture image obtained by a responce of a retina visual cell array model. A local area information-amount computation unit 14 is configured to: compute an amount of information for each local area of preset largeness in the retina output image; and, on the basis of the amount of information in the local area, compute a missing risk level map having a location in a field of view of the driver associated with a missing risk level, which becomes higher as the amount of information becomes smaller.SELECTED DRAWING: Figure 1
【課題】 ドライバー個々の視覚能力に応じた適切な注意喚起を行うことができるようにする。【解決手段】 網膜投影像推定部12は、外界画像と、ドライバーの視線の方向と、個人眼特性とに基づいて、ドライバーの網膜に投影される外界の映像である網膜投影像を推定する。網膜出力像推定部13は、網膜投影像が網膜視細胞配列モデルに投影されたときに、網膜視細胞配列モデルの反応によって得られる映像である網膜出力像を推定する。局所領域情報量演算部14は、網膜出力像内における予め設定された広さの局所領域ごとの情報量を演算し、局所領域における情報量に基づいて、ドライバーの視野内における位置と、情報量が少なくなるほど高くなる見落とし危険度とを対応付けた見落とし危険度マップを演算する。【選択図】 図1 |
