    • A method and apparatus for 3D scanning in which a transmission mask is projected on to the object scene and imaged by a camera, depth information being derived from the image by measurement of the illumination intensity from the camera image and computation from the measured intensity for the image, the mask having a first configuration having a transmission function f(x) varying regularly along its length and a second configuration having the same transmission function phase shifted by 180°, and means to project an image from each configuration on to the object scene.
    • 一种用于3D扫描的方法和装置,其中将透射掩模投射到对象场景并由相机成像,通过从照相机图像测量照射强度从图像导出深度信息,并根据测量的强度从 图像,具有具有沿着其长度规则变化的传播函数f(x)的第一配置的掩模和具有相移偏移180°的相同传输功能相位的第二配置,以及将每个配置的图像投影到对象场景的装置 。
