    • This invention introduces, as one aspect, a method for creating a three-dimensional object model, wherein an object is set to be modeled at a plurality of relative positions to a photographing position, the plurality of relative positions including a plurality of different longitudinal orientations and a plurality of latitudinal positions which has different latitudinal distances from a transparent table on which the object is to be placed, the plurality of latitudinal positions including a position below the transparent table, the object is photographed at the plurality of relative positions by using both a front lighting for a front side of the object confronting the photographing position and a back lighting for a back side of the object hidden from the photographing position, and control is carried out so that the object is photographed a plurality of times at a plurality of relative positions for obtaining a plurality of silhouette images in a first mode and is photographed a plurality of times at a plurality of relative positions for obtaining a plurality of texture images under a different lighting condition from the first mode in a second mode, the silhouette images and the texture images are to be used for creating the three-dimensional object model.
    • 本发明作为一个方面引入了一种用于创建三维物体模型的方法,其中物体被设置为在拍摄位置的多个相对位置处被建模,所述多个相对位置包括多个不同的纵向取向 以及多个纬度位置,其与待放置对象的透明台具有不同的纬度距离,所述多个纬度位置包括透明台下方的位置,通过使用两者在多个相对位置拍摄物体 面对拍摄位置的物体的前侧的前照明和隐藏于摄影位置的物体的背面的背光照射,并且进行控制,使得物体在多个摄影位置被多次拍摄 用于获得第一模式中的多个轮廓图像并被拍摄的相对位置 在第二模式下,在与第一模式不同的照明条件下获得多个纹理图像的多个相对位置处的时间精度,剪影图像和纹理图像将用于创建三维对象模型。

    • This invention introduces, as one aspect, an apparatus for creating three-dimensional object model, comprising photographing means for photographing an object to be modeled for obtaining images to be used for creating the three-dimensional object model, setting means for longitudinally and latitudinally setting a relative position between the object and said photographing means, said setting means being capable of setting the object and said photographing means a plurality of different relative longitudinal and latitudinal positions, and control means for controlling said photographing means and said setting means so that a number of photographs taken from different relative longitudinal positions at a first relative latitudinal position is larger than that taken from different relative longitudinal positions at a second relative latitudinal position, the first relative latitudinal position being closer to a lateral position than the second relative latitudinal position. Accordingly, it becomes possible to minimize the number of photographs for obtaining necessary images to effectively keep a high quality three-dimensional object model, the number of user's manual operations is reduced, and the total photographing time for creating a three-dimensional object model is significantly decreased.
    • 本发明作为一个方面引入了一种用于创建三维对象模型的装置,包括:用于拍摄待建模对象的拍摄装置,以获得用于创建三维对象模型的图像;纵向和横向设置的设置装置 物体和摄影装置之间的相对位置,所述设定装置能够设定物体和摄影装置多个不同的相对纵向位置和纬度位置,以及用于控制所述拍摄装置和所述设定装置的控制装置, 在第一相对纬度位置处从不同相对纵向位置拍摄的照片大于在第二相对纬度位置处从不同相对纵向位置取得的照片,第一相对纬度位置比第二相对纬度位置更靠近横向位置。 因此,可以最小化用于获得所需图像的照片的数量,以有效地保持高质量的三维对象模型,减少用户手动操作的次数,并且用于创建三维对象模型的总拍摄时间是 明显下降。
