  • Publication number: 20170160795
    Abstract: The embodiment of the present disclosure discloses a method and device for image rendering processing. The method comprises: detecting a state of a target head to generate a target state sequence; when determining that the target head enters into a moving state, simulating the target state sequence to generate a fitting curve; confirming a field angle of a target scene according to a pre-generated frame delay time and the fitting curve; rendering the target scene on the basis of the field angle to generate a rendered image. According to an embodiment of the present disclosure, the moving state of the target head can be predicted according to the fitting curve to compensate an estimated field angle deviation, then a field angle deviation of an image frame at the beginning and at the end of rendering can be effectively reduced.

  • Publication number: 20170161953
    Abstract: An embodiment of the present disclosure discloses a processing method and processing device for collecting sensor data. The method comprises: generating a fitted curve on the basis of historical sensor data; determining a target time corresponding to the target sensor data when detecting the target sensor data; calculating the target time according to the fitted curve, and obtaining virtual sensor data corresponding to the target time; comparing the target sensor data with the virtual sensor data, and eliminating abnormal target sensor data according comparison results. The embodiment of the present disclosure deletes abnormal target sensor data through detecting the degree of match between the target sensor data and the fitted curve, thus solving the problems of independent offset of image and difficult focusing during focus operation caused by abnormal sensor data.

  • Publication number: 20170163958
    Abstract: The embodiment of the present disclosure discloses a method and a device for image rendering processing. The method comprises the following steps: detecting states of a target head to generate a target state sequence; determining a state of the target head according to the target state sequence; if the target head is in a stable state, acquiring a quasi-scene image generated in advance from a scene cache region, and taking the acquired quasi-scene image as a target scene image; rendering, a video frame image on the basis of the target scene image to generate a rendered image. According to an embodiment of the present disclosure, as the states of the target head are detected, a scene rendering procedure may be canceled if the target head is in the stable state, the image rendering time may be shortened, the image rendering efficiency may be improved.

  • Publication number: 20160313799
    Abstract: The disclosure discloses a method and apparatus for identifying an operation event. The method includes obtaining sample points of a moving object. A preset number of points are fit in a list of points to a curve. It is determined whether the distance between the sample points and the curve is above a first threshold. When the distance is above the first threshold, the sample point is mapped onto the curve and the mapped point is stored into the list of points. When the distance is below or equal to the first threshold, the sample points are stored into the list of points. The operation event of the object is identified from the points in the list of points. With the disclosure, a dithering point of the moving object can be replaced by a point on a curve to eliminate dithering and improve the accuracy of identifying the operation event.
