2 results about "Pixel pair" patented technology

A present disclosure relates to a projector including a light source, an excitation light source, a wavelength converter, a collimator system that parallelizes fluorescence outputted from the wavelength converter, a light separator that separates the fluorescence into second light and third light, a correction lens provided in an optical path of the second or third light, a superimposing lens, a light modulator having a plurality of pixels each including first, second, and third sub-pixels, a microlens array including a plurality of microlenses corresponding to the plurality of pixels, and a projection optical apparatus. First light is incident on a first position on the superimposing lens, the second light is incident on a second position on the superimposing lens, the third light is incident on a third position on the superimposing lens The first light passes through the microlenses and is incident on the first sub-pixels. The second light passes through the microlenses and is incident on the second sub-pixels. The third light passes through the microlenses and is incident on the third sub-pixels.

The invention discloses a photography measurement method for scene of a traffic accident based on a multi-activity control system. The method comprises the following steps: designing a semi-cone activity control system with a smaller upper part and larger lower part; (2) arranging a plurality of (m) activity control systems on the scene of the traffic accident, and photographing digital pictures from various angles; (3) respectively calculating the m activity control systems in the pictures, thus obtaining straight linear conversion parameters, distortion coefficients and inner and outer orientation elements corresponding to the m activity control systems; (4) wholly calculating the m activity control systems in the pictures, thus respectively obtaining m straight linear conversion parameters, the agreed inner orientation elements and the distortion coefficients; and (5) selecting two pictures to form a three-dimensional pixel pair, selecting the same activity control systems, and calculating the three-dimensional coordinates of target points.
