    摘要： The present invention is to provide a method for enabling an electronic device to read at least two images taken from different positions by a digital camera mounted with a fisheye lens; acquire internal and external parameters of the fisheye lens corresponding to the different positions as well as the vignetting coefficient for eliminating the vignetting on the images; perform exposure compensation and color calibration on the images for letting them have consistent brightness and hues; project the images onto a spherical surface and spread out the spherical surface to form a two-dimensional spread-out picture based on the parameters; register the overlapped images projected on the two-dimensional spread-out picture and adjust the offset of corresponding pixels thereof, register and adjust the brightness and hues of the overlapped images into consistency; and fuse overlapped images together to produce a 360-degree spherical panorama without having any noticeable stitching seam between the images.

    摘要： The present invention discloses a short-range optical amplification module, which includes, sequentially from the image side to the object side, a reflective polarizing plate, a first phase delay plate, a third lens and a second phase delay plate, wherein the short-range optical amplification module further includes a first lens and/or a second lens that are/is located on either side of any one of the reflective polarizing plate, the first phase delay plate, the third lens and the second phase delay plate. In the third lens, the optical surface adjacent to the second phase delay plate is a transflective optical surface; the reflection surface-containing focal length f 3 of the third lens meets the following condition: 1F‰¤f 3 ‰¤2F, wherein F is the focal length of the short-range optical amplification module. By performing parameter refining on the f 3 that influences the optical amplification effect, the module can keep a small overall thickness while obtaining a large optical amplification effect and it can be applied in a small-size VR device, so that the VR device can realize a wide field angle, a large eyebox and high-quality imaging effect, and hence a better user experience.

    摘要： The present invention discloses a short-range optical amplification module, spectacles, a helmet and a VR system. The amplification module includes a reflective polarizing plate, a first phase delay plate, a second lens and a second phase delay plate that are arranged in turn, and a first lens is further set on either side of any one of the reflective polarizing plate, the first phase delay plate, the second lens and the second phase delay plate. In the second lens, the optical surface adjacent to the second phase delay plate is a transflective optical surface. The first focal length f2 of the second lens meets the condition: 1F≤f2≤2F, wherein F is the system focal length of the optical amplification module. By performing parameter refining on the first focal length f2 that influences the optical amplification effect, the module can keep a small overall thickness while obtaining a large optical amplification effect, and the VR device can realize a good field angle, a large oculomotor range and a high-quality imaging effect, and hence a better user experience.
