Description
Technical Field
The invention relates to the technical field of laser projection display, in particular to a three-dimensional space laser projection slice display device.
Background
The laser projection display technology takes red, green and blue tricolor lasers as light sources, can truly reproduce rich and bright colors of an objective world, and provides more shocking expressive force. The color gamut coverage rate of the color gamut display device can reach more than 90% of the color space which can be identified by human eyes, is more than twice of the traditional display color gamut coverage rate, thoroughly breaks through the defects of the color gamut space of the display technology of the first three generations, and realizes the perfect color restoration.
In order to make the displayed scene and object have three-dimensional effect and make the watching effect vivid and clear, the development of 3D technology makes the picture become three-dimensional and vivid, the image is no longer limited on the plane of the screen, and the image seems to be capable of going out of the screen, so that the audience has a feeling of being personally on the scene. The 3D display technology can show the depth, the layering and the reality of images, is widely applied to the fields of film and television, military officers, video communication and medicine, and brings more shocking stereoscopic impression.
Compared with the 3D display technology, the method has more practical significance and strategic value for the internal information exploration of the 3D image. Similar to the CT vertical slice technique in the medical field, more internal structural and texture details can be acquired by internal vertical slicing of the 3D image. However, due to the complexity of the internal structure and texture, the vertical slicing technique does not express enough internal details, so that the slicing technique at any angle is necessary to be developed. By means of the technology, a radiologist can acquire slice imaging of any angle of a three-dimensional virtual image in real time only by freely orienting and operating a projection flat plate, so that the radiologist can better analyze pathology and make scientific judgment; a geologist can obtain geological slice images at any angle, so that geological investigation and prevention of geological disasters can be better performed; architects can obtain the internal structure of the building in real time, and the integrated structure optimization of the stability of the internal structure is convenient to feel from the appearance. The operation can be realized by only using a common flat plate which can be used as a passive and unconstrained projection screen and a control input device, can be freely oriented and operated above a calibrated projector, and can acquire slice images of certain three-dimensional data at any angle from the projection flat plate at any time.
In the aspect of slice scan display technology, vertical slice technology is generally adopted, and slice display at any angle cannot be realized. In the field of laser projection display, a laser light source is generally adopted to emit light beams, and an optical machine realizes light path adjustment through reflection, and is mainly applied to two-dimensional display technologies such as laser projection televisions and the like. However, slice imaging of a three-dimensional spatial virtual object at an arbitrary angular plane cannot be acquired.
In summary, a three-dimensional space laser projection slice display device is designed, which can obtain slice images of a three-dimensional space virtual object on any angle plane, and is a technical problem that needs to be solved urgently at present.
