    • A structured-light measuring method, includes: matching process, in which the number and the low-precision depth of a laser point are achieved by using the imaging position of the laser point on a first camera (21) according to a first corresponding relationship in a calibration database, and the imaging position of the laser point on a second camera (22) is searched according to the number and the low-precision depth of the laser point so as to acquire the candidate matching points, then the matching process is completed according to the imaging position of the first camera (21) and the candidate matching points of the imaging position of the first camera (21) on the second camera (22) so that a matching result is achieved; and computing process, in which the imaging position of the second camera (22) matching with the imaging position of the first camera (21) is achieved according to the matching result, and then the precision position of the laser point is determined by a second corresponding relationship in the calibration database. A structured-light measuring system utilizes the above measuring method.

    • An image display device includes region of interest extraction unit, parallax image generation unit and 3D image display unit. Region of interest extraction unit generates depth image signal by depth image conversion employing depth threshold, depth image signal including information on distance in three-dimensional space between viewpoint and each pixel of two-dimensional image including region of interest desired to be noted by observer, depth image conversion being such that depth value indicating distance between viewpoint and each pixel of two-dimensional image is converted to depth value for 2D display when depth value is equal to or larger than depth threshold. Parallax image generation unit generates both-eye parallax image having parallax in region of interest alone, from two-dimensional image and image obtained by conversion of region of interest image representing region of interest at each of both-eye viewpoints, based on two-dimensional image and depth image signal. 3D image display unit displays both eye parallax image.
    • 图像显示装置包括感兴趣区域提取单元,视差图像生成单元和3D图像显示单元。 感兴趣区域提取单元通过使用深度阈值的深度图像转换生成深度图像信号,深度图像信号包括关于视点与视点之间的三维空间中的距离的信息的深度图像信号,包括期望由观察者注意的感兴趣区域的二维图像的每个像素, 深度图像转换使得当深度值等于或大于深度阈值时,指示视点与二维图像的每个像素之间的距离的深度值被转换为2D显示的深度值。 视差图像生成单元基于二维图像生成具有视点的双眼视差图像,二维图像和二维图像中的每个双眼视点的感兴趣区域的图像表示获得的图像 图像和深度图像信号。 3D图像显示单元显示双眼视差图像。
