The invention discloses a 360-degree high-definition surround view panoramic lens and belongs to the field of optical lenses. The 360-degree high-definition surround view panoramic lens is realized by adopting a small number of lenses and arranging the lenses in a certain way, and in this way, production cost is reduced. The lens is composed of a reflector, a lens assembly with positive focal power, and an optical filter, wherein the reflector is a non-spherical reflector, and the lens assembly with positive focal power comprises a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, a seventh lens and an eighth lens. The lens is lower in production cost, simple in structure, low in manufacturing cost, and capable of achieving the resolution ratio of 1080P and 720P high-definition detector. The pick-up lens has a unique property of 360-degree observation, all personnel and activities can be seen, target determination speed is increased, emergencies can not be missed, and panoramic monitoring is realized in the true sense.

The invention relates to a wide-angle lens and a camera; the lens comprises a former group with the negative optical power, a latter group with the positive optical power and an optical filter, wherein the former group comprises a first concave lens and a second concave lens; the latter group comprises a first convex lens, a second convex lens and a third convex lens which are arranged in sequence from an object space to an image space; and the optical filter is arranged at the back of the third convex. The invention also provides the camera based on the wide-angle lens; the wide-angle lens adopts the fewer lenses and achieves the greater viewing field angle according to the arrangement of all the lenses and reduces the manufacturing cost thereof. The wide-angle lens has simple structure,reduces the production difficulty thereof and low manufacture cost; the optical overall length of the wide-angle lens is less than 28mm; the height of the module of the wide-angle lens can be designed to be shorter so that the wide-angle lens can be used as vehicle-mounted wide-angle lens, monitoring lens and the like to be used and better meets the smallness and skillfulness of the camera; and the full viewing field of the wide-angle lens reaches 200 degrees, which can meet the wider view finding range.

The invention relates to a laser projection display technique, and provides a head-up display system based on a laser light source. The head-up display system comprises a laser light source component, a light source control unit, a light intensity sensor, a display chip, a display chip control unit, a system control unit and a transparent screen, wherein the transparent screen is made of a transparent medium doped with at least three nano grains of different particle sizes; the nano grain of each particle size has a fixed resonance rayleigh scattering wavelength; the wavelengths correspond to the lighting wavelengths of the laser light source one to one; each kind of laser can form resonance rayleigh scattering on the screen, so as to form practical images. The head-up display system has the characteristics of wide visible range, simple optical design, vivid color and the like, the optical energy utilization rate of the light source is high.

The present invention provides a remote transmission system and method for holographic images, which separates the middle area where key targets are located from the intended imaging scene for independent holographic image generation, and uses relatively data-saving methods for the background and surrounding parts of the intended imaging scene. Quantitative non-holographic imaging; furthermore, for the generation process of the holographic image, the present invention performs necessary data volume reduction processing; finally, remote transmission of mixed data of holographic and non-holographic images. In the reproduction process, for the mixed data received remotely through the communication network, the holographic and non-holographic images are respectively restored, and the holographic and non-holographic images are synthesized for display.
