The invention provides a three-dimensional perspective method and system. The perspective system comprises a first semitransparent and semi-reflecting mirror, two projectors which are in the orthogonal polarization state, a second semitransparent and semi-reflecting mirror and a registering device. The perspective method comprises the steps that the image of a perspective target is projected to the first semitransparent and semi-reflecting mirror by the two projectors which are in the orthogonal polarization state so that two two-dimensional images with preset parallax are formed; the second semitransparent and semi-reflecting mirror is arranged at one side, which is away from the projectors, of the first semitransparent and semi-reflecting mirror, and one end of each of the two semitransparent and semi-reflecting mirrors is coaxially connected to form a hinge type structure so that two corresponding two-dimensional virtual images are formed at the positions axially symmetrical about the second semitransparent and semi-reflecting mirror by the two two-dimensional images respectively; a three-dimensional virtual image formed by superposition of the two two-dimensional virtual images is acquired through observation at the first position by means of passive polarized glasses; and the three-dimensional virtual image is in registration with the perspective target. The three-dimensional perspective method and system are simple in realization and low in cost and can be applied to image guided surgical navigation for assisting doctors' surgery.
Description
technical field [0001] The invention relates to a stereoscopic perspective method and system, in particular to a stereoscopic perspective method and system based on double projectors and half mirrors. Background technique [0002] At present, stereoscopic imaging in the industry mainly includes naked-eye stereoscopic imaging and non-naked-eye stereoscopic imaging. [0003] Naked-eye stereoscopic imaging is to adjust the angle of light so that the left and right images are input to the left and right eyes respectively. It is specifically divided into three methods: lenticular lens, parallax barrier and pointing light source. The lenticular lens method has a complex imaging structure and high cost, and images may overlap when viewed from an inappropriate angle. In the parallax barrier mode, the light in some directions is blocked, the brightness is low, and the resolution loss is serious. Pointing to the light source method, the imaging structure is extremely complex, and th...
