    摘要: Disclosed are a virtual viewpoint combination method and device in a multi-viewpoint video, improving the quality of the virtual viewpoint images and improving the display effects of the virtual viewpoint images under the premise of not introducing geometrical distortion. The method includes: taking two viewpoint images provided by a first camera and a second camera as reference viewpoint images, and respectively performing 3D image conversion, pinhole filling, image compensation and image convergence processing on the two viewpoint images to obtain a main virtual viewpoint image; then respectively performing depth-image processing, 3D image conversion, pinhole filling, image compensation and image convergence processing on the two viewpoint images to obtain a subordinate virtual viewpoint image; and performing filling the remaining holes in the main virtual viewpoint image on the basis of the subordinate virtual viewpoint image to obtain a final virtual viewpoint image to be combine.

    摘要: This invention is a projector headlight that, while offering dual beam patterns, boasts a 100% utilization of the light emitted from a light source by one of the following methods: (1) employing a reflective cutoff shield means to reflect the incoming light from said light source back to the reflector to enhance the illumination in low-beam pattern, (2) using reversible cutoff shield means to reflect the incoming light from said light source back to the reflector to enhance the illumination in low-beam pattern with no moving part involved, (3) utilizing a selective light-filter cutoff means to selectively reflect the incoming light from said light source back to the reflector to enhance the illumination in low-beam pattern without making use of any moving part, (4) using a low-beam light-emitting subassembly and a high-beam light-emitting subassembly that are separated by partition means to achieve dual beam patterns with no moving part, or (5) adopting a low-beam light-emitting subassembly in low-beam pattern and a high-beam light-emitting subassembly in high-beam pattern without any moving part.

    摘要: A system may create work units, each work unit including at least one of an input port or output port, each work unit configured to modify data that is received via the input port. In addition, the system may compose a workflow by connecting an output port of a first of the work units to an input port of a second of the work units, receive a work order, select the workflow in response to the work order, decompose the workflow into constituent work units, instantiate tasks that correspond to the constituent work units, and execute a work unit process for each of the tasks.
