IMAGE PROCESSING APPARATUS, IMAGE PROCESSING METHOD, AND DATA STRUCTURE OF IMAGE FILE

摘要

In an image processing apparatus, a sensor output data acquisition unit acquires data of layered image information from a sensor group. A slice image generation unit generates data of a two-dimensional image for each slice plane surfaces in which distribution is acquired. An image axis conversion unit generates similar data of a two-dimensional image for a plurality of plane surfaces that are perpendicular to an axis different from a sensor axis. A slice image management unit of a display processing unit manages a slice image that is used for drawing according to the position of a viewpoint or the like. Memory for drawing sequentially stores data of an image necessary for drawing. An additional object image storage unit stores image data of an object that is additionally displayed such as a cursor or the like. An image drawing unit draws a three-dimensional object using data of the slice image.

主权项

1. An image processing apparatus comprising:
a data acquisition unit configured to acquire distribution information of values obtained on a plurality of slice surfaces that intersect at the same angle with a predetermined axis at different positions on the predetermined axis; a slice image generation unit configured to generate, for each of the slice surfaces, a slice image that expresses the distribution information as an image by determining a pixel value that includes an alpha value based on a value at each position on the slice surfaces; and an image drawing unit configured to display, as a three-dimensional object, a three-dimensional space that is formed by the plurality of slice surfaces by arranging the slice image at a corresponding position on the axis and performing alpha blending drawing according to the position of a viewpoint that is input.
