  • Patent number: 10742952
    Abstract: A 3D reconstruction method is provided. Positioning signals are received by a signal receiver at a first and a second time spots to determine a HMD displacement vector and a HMD rotation amount. A first and a second images are retrieved by a first camera to determine a first camera rotation amount. A relative rotation amount and a relative displacement vector between the HMD and the first camera are calculated. A first camera displacement vector of the first camera is calculated according to the HMD displacement vector, the HMD rotation amount, the relative rotation amount and the relative displacement vector. Depth information of the first and the second image is obtained based on the first camera displacement vector and the first camera rotation amount. 3D reconstruction is performed according to images retrieved by the first camera and the depth information.

  • Patent number: 10681486
    Abstract: A method for obtaining Hi-Res audio transfer information is provided. The method is applicable to the electronic device having a processor. In the method, a first audio signal is captured and converted from the time domain into in the frequency domain to generate a first signal spectrum. Then, a regression analysis is performed on an energy distribution of the first signal spectrum to predict an extended energy distribution according to the first signal spectrum, and head-related parameters are used to compensate for the extended energy distribution to generate an extended signal spectrum. Finally, the first signal spectrum and the extended signal spectrum are combined into a second signal spectrum which is converted from the frequency domain into the time domain to generate a second audio signal including Hi-Res audio transfer information.

  • Publication number: 20190122681
    Abstract: A sound reproducing method used in sound reproducing apparatus that includes the steps outlined below is provided. An input sound signal related to listener data and sound source data is received. An encoding process is performed by multiplying the input sound signal by an encoding function matrix having entries related to a basis function to generate an encoding result. A decoding function matrix is retrieved from the storage and at least one direction parameter is applied to the decoding function matrix, wherein the decoding function matrix compensates a difference between an ideal approximation result and a modeled approximation result of the input sound signal. A decoding process is performed by multiplying the encoding result by the decoding function matrix having the direction parameter applied to generate an output sound signal. The output sound signal is reproduced.

  • Publication number: 20190116441
    Abstract: A sound reproducing method used in sound reproducing apparatus that includes the steps outlined below is provided. A sound signal is generated with a 3D sound generating process according to listener data and sound data. Pre-recorded sound data is retrieved to further generate a target distance function corresponding to the sound distance. A fixed head-related transfer function corresponding to a fixed distance is retrieved. A target head-related transfer function corresponding to the sound distance is generated by adapting the target distance function to the fixed head-related transfer function. The sound signal is reproduced by multiplying the sound signal by the target head-related transfer function.
