This invention provides a three-dimensional image photography system (30), comprising: a three-dimensional measuring instrument (4) which is equipped in a construction having a room in which a patient support table (3) is provided and generates three-dimensional image data by shooting image to a patient (45) and a three-dimensional image processing unit (6) which generates a three-dimensional image (26) according to the three-dimensional image data and shows the three-dimensional image (26), wherein the three-dimensional image (26) is correlated to a reference coordinate system which uses a top plate (1) or the floor in the room (9) as a reference. The three-dimensional image processing unit (6) has: a position information extraction unit (73) which obtains the relevant relationship of the patient’s (45) three-dimensional position information in the reference coordinate system and the three-dimensional image data and generates patient’s (45) reference coordinate system position information according to the reference coordinate system and a display unit (72) that displays the three-dimensional image (26) the display unit (72) displays the reference image and the observed image of the three-dimensional image (26) shoot at different timing.根據本發明之三維畫像攝影系統(30),係具備:三維量測器(4),係配置於設置有患者支撐台(3)之房間的房間構造物,且進行患者(45)的拍攝來生成三維影像資料;及三維畫像處理裝置(6),係根據三維影像資料生成三維影像(26)並且顯示該三維影像(26),該三維影像(26)係被賦予關聯於以頂板(1)或房間的地板(9)為基準之基準座標系統。三維畫像處理裝置(6)係具有:位置資訊抽出部(73),係取得基準座標系統與三維影像資料中患者(45)的三維位置資訊之相關關係,生成依據基準座標系統之患者(45)的基準座標系統位置資訊;及顯示部(72),係顯示三維影像(26);顯示部(72)係顯示在不同時序拍攝之三維影像(26)之基準畫像及觀察畫像。1‧‧‧頂板2‧‧‧驅動裝置3‧‧‧患者支撐台4‧‧‧3D相機(三維量測器)5‧‧‧支柱6‧‧‧三維畫像處理裝置7‧‧‧LAN通信線8a、8b‧‧‧通信線9‧‧‧地板10‧‧‧轉台30‧‧‧三維畫像攝影系統45‧‧‧患者69‧‧‧頂部If‧‧‧等深點It‧‧‧中心點
