    • A method for making an image of an object including depth information comprising the steps of: illuminating the object with a periodic pattern of light from an illuminating arrangement; the illuminating arrangement being such that the pattern is in focus in a focal plane and defocuses progressively away from said focal plane; the object being placed such that different parts of it are at different distances from the focal plane; capturing image data from the thus-illuminated object; analyzing the captured image data to extract depth information based on the extent of defocusing of the pattern; and displaying an image of the object without the pattern and with depth information. Apparatus or carrying out the method, comprising an illuminating arrangement adapted to illuminate the object with a periodic pattern of light; the illuminating arrangement being such that the pattern is in focus in a focal plane and defocuses progressively away from said focal plane; the object being locatable with respect to the illuminating arrangement such that different parts of it are at different distances from the focal plane; image data capturing means adapted to capture image data from the thus illuminated object; data analysis means adapted to analyze captured image data to extract depth information based on the extent of defocusing of the pattern; and image display means for displaying an image of the object without the pattern and with depth information.
    • 一种用于制作包括深度信息的物体的图像的方法,包括以下步骤:用来自照明装置的周期性图案照明物体; 所述照明装置使得所述图案在焦平面中聚焦并且逐渐离开所述焦平面而散焦; 物体被放置成使得其不同部分处于与焦平面不同的距离; 从如此照亮的对象捕获图像数据; 基于所述图案的散焦程度,分析所捕获的图像数据以提取深度信息; 并且显示对象的图像而不具有图案和深度信息。 装置或执行该方法,包括适于以周期性图案照射物体的照明装置; 所述照明装置使得所述图案在焦平面中聚焦并且逐渐离开所述焦平面而散焦; 物体可相对于照明装置定位,使得其不同部分处于与焦平面不同的距离; 图像数据捕获装置,适于从如此照射的物体捕获图像数据; 数据分析装置,适于基于所述图案的散焦程度来分析所捕获的图像数据以提取深度信息; 以及用于在没有图案和深度信息的情况下显示对象的图像的图像显示装置。
