Problems solved by technology
Naked-eye stereoscopic 3D display has considerable commercial prospects. Most of the stereoscopic 3D display devices that have gone out of the laboratory stage are complex in structure, heavy and require a variety of materials and equipment and self-designed control devices, which are not suitable for applications in mobile applications. Strong virtual reality technology

Embodiment Construction
[0047] Preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention, and are not intended to limit the protection scope of the present invention.
[0048]The following uses an exemplary embodiment to illustrate the application platform of the embodiment of the present invention. Among them, two image acquisition units with a reference line of 60 mm can be used to simulate the eyes of a person, and they are placed at a distance of about 300 mm from the screen of the mobile terminal. A sealed experimental box is used to provide a closed environment isolated from external light for the optical path acquisition of the image acquisition unit, and a fan is installed behind the image acquisition unit for heat dissipation. Preferably, in order to maximize the use of pixels on the captured image,...

The invention relates to a moving naked eye 3D virtual reality method and system based on optical path acquisition. The method includes acquiring images; obtaining the two-viewpoint synthesis graph index plan according to the acquired images; obtaining the two viewpoint graphs according to the position information of the acceleration and the rotation information of the angular velocity; and rendering the two viewpoint graphs to form the synthesis graph to obtain a 3D virtual reality display image based on the two-viewpoint synthesis graph index plan of the images. Preferably, the processes for obtaining the two viewpoint graphs include determining the influence weight of the sub-pixel brightness on the images, and determining the two-viewpoint synthesis graph index plan by means of least squares method with the bounding box; and adjusting the orientation of the acquired images to obtain the two viewpoint graphs according to the position information of the acceleration and the rotation information of the angular velocity. According to the invention, the technical problem of realization of high-quality naked eye 3D virtual reality display can be solved.
Description
technical field [0001] The invention relates to a three-dimensional display method, in particular to a method and system for moving naked-eye three-dimensional virtual reality based on optical path acquisition. Background technique [0002] At present, virtual reality has set off a wave in the world, and three-dimensional virtual reality is a relatively new development direction. Virtual reality technology is a comprehensive achievement that integrates tracking system, haptic system, image generation and display system and visual display equipment, but there are still many problems to be solved on the road to practical commercialization. Virtual reality mostly integrates related technologies through wearable device helmets, but the size of the headband cannot be adjusted, the helmet is too heavy, and the device has poor ventilation and heat dissipation when worn for a long time. These factors will reduce the comfort experience of the viewer; The actual equipment needs to be...
