  • Patent number: 11662828
    Abstract: A method for identifying an object, an optical sensing apparatus and a system are provided. A controller of the system drives multiple light sources of the optical sensing apparatus to emit the multiple light beams with different beam angles, controls a light sensor to sense the lights reflected by the object, and performs the method for identifying the object. In the method, the light sensor is used to sense a first light emitted by a first light source with a first beam angle reflected by the object, and sense an intensity of the reflected first light. The light sensor is also used to sense a second light emitted by a second light source with a second beam angle reflected by the object and sense another intensity of the reflected second light. Therefore, the object can be identified by integrating information of the intensities obtained by the light sensor.

  • Patent number: 11614408
    Abstract: A method for improving an identification accuracy of mixture components by using a known mixture Raman spectrum is disclosed. After calculating a first similarity between a to-be-tested Raman spectrum characteristic vector group and a pure substance Raman spectrum characteristic vector group of an nth kind of pure substance in a Raman spectrum standard library, the method uses a known mixture library to calculate to obtain a second similarity between a to-be-identified substance Raman spectrum characteristic vector group and a spectral peak characteristic vector group with offset information corresponding to a pure substance in a known mixture, and determines a similarity between a to-be-tested mixture and the nth kind of pure substance according to the first similarity and all second similarities to thus obtain a component identification result. The present application uses the known mixture library to assist the Raman spectrum standard library in searching.

  • Patent number: 11585936
    Abstract: In a range imaging camera, a first range image producing unit produces a first range image by calculating a distance to an object on the basis of the delay time or the received light amount of each pixel produced by a light receiving processing unit. A second range image producing unit produces a second range image by performing filtering for each pixel of the first range image using a group of neighboring pixels including its own pixel. In this case, a pixel group selection unit selects a group of pixels used in the filtering such that at least one of produced values including the delay time and the received light amount produced by the light receiving processing unit and the first range image produced by the first range image producing unit is equal to or larger than a noise component value.
