  • Publication number: 20240087343
    Abstract: A license plate classification method, a license plate classification apparatus and a computer-readable storage medium are provided. The method includes: performing a license plate recognition process on a first license plate image to obtain a license plate recognition result; performing an encoding process on the license plate recognition result to obtain a first license plate feature; performing a feature extraction process on the first license plate image to obtain a second license plate feature; and processing the first license plate feature and the second license plate feature through a classification network to obtain a first license plate classification result. In this way, an accuracy of license plate classification is improved.

  • Patent number: 11542430
    Abstract: A method for preparing fluorescent-encoded microspheres coated with metal nanoshells is disclosed herein. By using SPG method, metal nano-material modified with a certain ligand is used as a new surfactant in the emulsification process, and different kinds and different amounts of fluorescent materials are doped into polymer microspheres to prepare fluorescent-encoded microspheres with different fluorescent-encoded signals and uniformly coated metal nanoshells in one step. The prepared fluorescent-encoded microsphere comprises a metal nanoshell, a polymer, and a fluorescent-encoded material. The fluorescent-encoded microsphere has a particle size of 1 ?m˜20 ?m, CV of less than 10%, which can be used for protein/nucleic acid detection.

  • Publication number: 20220299441
    Abstract: Disclosed are a detection method and detection system using suspension liquid biochip detection. The detection method using suspension liquid biochip comprises the following steps: an excitation step and a signal acquisition step. In the excitation step, a laser light emitted by a single laser device is used to excite a classification fluorescence of nanocrystalline fluorescent microspheres and a report fluorescence of an object to be detected; and in the signal acquisition step, fluorescence detection signals are obtained through multiple acquisition channels, respectively. In the present invention, the classification fluorescence in the nanocrystalline fluorescent microspheres and the report fluorescence in the object to be detected in a sample are excited by a single laser device, which is convenient for operation and reduces the production cost of the system, thereby reducing the detection cost.

  • Publication number: 20210404826
    Abstract: Technologies are provided for generation of exertion-aware paths. Some embodiments include a computing system that can generate a path based at least on first data defining a terrain, second data defining a target level of total work, and third data defining a target level of perceived difficulty. The computing system also can generate a road surface along the path. Generating the road includes embedding metadata defining position-dependent resistance forces based on a physics model, the metadata controlling force feedback at virtual-reality equipment. The computing system also can supply the road surface to the virtual-reality equipment.
