POINT-OF-GAZE DETECTION DEVICE, POINT-OF-GAZE DETECTING METHOD, PERSONAL PARAMETER CALCULATING DEVICE, PERSONAL PARAMETER CALCULATING METHOD, PROGRAM, AND COMPUTER-READABLE RECORDING MEDIUM
A point-of-gaze detection device according to the present invention detects a point-of-gaze of a subject toward a surrounding environment. The device includes: an eyeball image obtaining means configured to obtain an eyeball image of the subject a reflection point estimating means configured to estimate a first reflection point, at which incoming light in an optical axis direction of an eyeball of the subject is reflected, from the eyeball image a corrected reflection point calculating means configured to calculate a corrected reflection point as a corrected first reflection point by correcting the first reflection point on the basis of a personal parameter indicative of a difference between a gaze direction of the subject and the optical axis direction of the eyeball and a point-of-gaze detecting means configured to detect the point-of-gaze on the basis of light at the corrected reflection point and light in the surrounding environment.本發明提供注視點檢測裝置、注視點檢測方法、個人參數算出裝置、個人參數算出方法、程式、以及電腦可讀取的記錄媒體。本發明的注視點檢測裝置,係一種檢測受試者對周邊環境之注視點的注視點檢測裝置,具備:眼球圖像取得手段,其取得受試者的眼球圖像;反射點推定手段,其藉由眼球圖像推定來自受試者眼球的光軸方向的光所反射的第1反射點;修正反射點算出手段,其根據顯示受試者的視線方向與眼球的光軸方向之差的個人參數來修正第1反射點,並算出修正之後的第1反射點即修正反射點;注視點檢測手段,其根據修正反射點的光與周邊環境的光進行檢測注視點。A‧‧‧受試者PoG‧‧‧注視點GRP‧‧‧第1反射點100‧‧‧注視點檢測裝置102‧‧‧眼球圖像取得手段104‧‧‧反射點推定手段106‧‧‧修正反射點算出手段108‧‧‧注視點檢測手段110‧‧‧姿勢算出手段112‧‧‧環境光檢測裝置
