Embodiment Construction

[0021] The present invention will be further described below in conjunction with drawings and embodiments.

[0022] figure 1 It is a schematic diagram of a known fixed-axis rotation bitmap type volume display method. The imaging screen 1 rotates on a fixed axis, and the inertial force is easy to balance. The imaging space of the imaging screen 1 (shown by hatching, the same below) can be equal to the scanning space (shown by shadow, the same below), so the occupied space of the display space The ratio reaches the maximum value of 100%; from the perspective of the time duty cycle, there is a two-dimensional image displayed at any time, so the time duty cycle also reaches the maximum value of 100%. In such methods, the size of the imaging screen 1 may be equal to the size of the two-dimensional cross-sectional image; if the two-dimensional cross-sectional image is a rectangle, the three-dimensional imaging space is a cylinder.

Abstract

The invention discloses a bitmap volume display method for single screen circular translation. A two-dimensional image representing a three-dimensional scene cross section is shown on an imaging screen for circular translation, bitmap information of the two-dimensional image and a display position of the two-dimensional image on the imaging screen are updated dynamically according to a real-time position of the imaging screen, so as to form a parallel, time-division two-dimensional image sequence, and the two-dimensional image sequence is sensed and reduced by an observer by using a persistence-of-vision effect so as to obtain a three-dimensional scene. Compared with the display method in the background technology, voxels are uniform and force of inertia is balance, further, a drive mechanism is simplified remarkably, and a duty ratio of a display space and a duty ratio of display time are increased. The method is particularly suitable for accurate display of a three-dimensional imageand has a bright application prospect in fields relating to three-dimensional image display, such as industrial design, scientific research, teaching demonstration, medical CT analysis, and spatial mechanism motion.

Description

technical field [0001] The invention relates to a three-dimensional image display method, in particular to a single-screen circular translation bitmap type volume display method. Background technique [0002] According to the number of imaging screens and their mechanical scanning motion, the disclosed bitmap volume display methods can be classified into three types: fixed axis rotation type, reciprocating movement type and multi-screen translation type. [0003] fixed axis rotation figure 1 As shown, there is only one imaging screen, and the mechanical scanning motion of the imaging screen is fixed-axis rotation. The advantage is that the inertial force is easy to balance, and the duty cycle of the display space and the display time are both maximized; the limitation is that the size and distribution of the voxels are not uniform, but grow linearly from the shaft to the outside, so it does not Suitable for precise display of 3D images. [0004] reciprocating movement suc...
