A three-dimensional volume data rendering method and its application, and a three-dimensional image display method

Abstract

The invention provides a three-dimensional data drawing method, application thereof and a three-dimensional image display method, belonging to the technical field of three-dimensional imaging. The three-dimensional data drawing method comprises the following steps of building and drawing a left visual point and a right visual point of three-dimensional data based on a human eye model and a three-dimensional data matrix; enabling a light ray to pass through a pixel point in an imaging plane and project towards the three-dimensional data matrix separately from the left visual point and the right visual point; carrying out iterated integral on color and opaqueness in the three-dimensional data matrix along a light ray direction; and obtaining a three-dimensional image on the imaging plane, wherein the left visual point forms a left-eye image, and the right visual point forms a right-eye image. By the three-dimensional data drawing method, depth information is reserved in the drawn image, a layering sense is achieved, and the calculation is simple.

Description

technical field [0001] The invention relates to the technical field of three-dimensional imaging, in particular to a three-dimensional volume data rendering method and its application, and a three-dimensional image display method. Background technique [0002] Currently, the 3D (three dimensional, three-dimensional) display technologies on the market are generally based on the principle of using different image signals recognized by two eyes to display a three-dimensional effect. The shutter-type 3D technology is to increase the refresh rate, so that the image data to be seen by the left and right eyes is output in time intervals, and then through the cooperation with the shutter-type glasses, when the right-eye glasses are closed, the left eye sees the image of the left eye, and the left eye When the glasses are closed, the right eye looks at the image of the right eye, so that the two eyes see different pictures that are switched rapidly, thereby creating an illusion in th...

Problems solved by technology

Although this method can reflect the overall and internal information of the data field, it is difficult to determine the boundary of the object because of its implicit surface rendering mode, and the drawn image often does not retain depth information, so it is difficult to produce a sense of hierarchy and affect the three-dimensional effect , at the same time, the ray projection method has a large amount of calculation, the process is cumbersome, and it is difficult to achieve the rapidity of drawing images

On the other hand, due to the limitation of the display screen, the 3D image data can only be displayed on the 2D screen, which will cause the loss of a lot of depth information
