To accurately detect an occupant's line of sight taking into account the type of object of interest an occupant of a moving vehicle is gazing at.SOLUTION: Provided is a line of sight estimation device that estimates which object of interest among a plurality of objects of interest including an object of interest existing on the structure of a moving vehicle and a target existing in the surrounding of the moving vehicle, the line of sight of an occupant of the moving vehicle is directed to. The line of sight estimation device calculates the value of probability of the occupant visually recognizing each of the plurality of objects of interest, on the basis of the line of sight and a probability distribution that represents the probability of the occupant visually recognizing each of the plurality of objects of interest, and estimates that the occupant is gazing at the object of interest whose value of probability is greater than or equal to a threshold.SELECTED DRAWING: Figure 1

    【課題】移動体の乗員が注視する注視対象の種類を考慮して、当該乗員の視線を正確に検出すること。【解決手段】移動体の乗員が、前記移動体の構造体上に存在する注視対象と移動体の周辺にある物標とを含む複数の注視対象のうち、いずれの注視対象へ視線を向けているか推定する視線推定装置であって、前記視線推定装置は、前記視線と、前記乗員が前記複数の注視対象の各々を視認している確率を表す確率分布とに基づいて、前記乗員が前記複数の注視対象の各々を視認している確率値を算出し、前記確率値が閾値以上である注視対象に前記乗員が視線を向けていると推定する、視線推定装置。【選択図】図1
