摘要： A method of calibrating an image acquisition device (1) comprises:
- emitting at least one light source pattern in an object space of the image acquisition device;
- adjusting one of the source patterns until an image pattern of the source pattern formed on a sensor (43) of the image acquisition device exhibit a shape which centroid corresponds to a centroid of a reference pixel (P ref ) of the sensor, called a target image pattern (42 2 , 46 2 );
- analyzing the adjusted source pattern (41 2 , 44 2 ) and estimating therefrom at least one characteristic of a pixel beam directed to the reference pixel from the adjusted source pattern.

摘要： There are several types of plenoptic devices and camera arrays available on the market, and all these light field acquisition devices have their proprietary file format. However, there is no standard supporting the acquisition and transmission of multi-dimensional information. It is interesting to obtain information related to a correspondence between pixels of a sensor of said optical acquisition system and an object space of said optical acquisition system. Indeed, knowing which portion of the object space of an optical acquisition system a pixel belonging to the sensor of said optical acquisition system is sensing enables the improvement of signal processing operations. The notion of pixel beam, which represents a volume occupied by a set of rays of light in an object space of an optical system of a camera along with a compact format for storing such information is thus introduce.

摘要： A projection image of a three dimensional image is generated and displayed and a three dimensional target point corresponding to a designated two-dimensional target point is set to the three dimensional image. A reference cross-section is set to the three dimensional image by using the three dimensional target point. A cross-sectional two-dimensional image of the reference cross-section in which an object close to a point of view that faces the reference cross-section is not displayed is generated. An instruction to change the position of the point of view, using the three dimensional target point based on the cross-sectional two-dimensional image as a reference point, in order to align an observation direction of a structure to which the three dimensional target point is set with a target three dimensional direction is received. A new reference cross-section is set. A new cross-sectional two-dimensional image of the new reference cross-section is generated.
