  • Publication number: 20160148436
    Abstract: Framework for processing a point cloud of an object includes an electronic device coupled to a testing device. The testing device includes a worktable and a scanning device. The worktable has a number of labeled points. The electronic device controls the worktable to rotate at predetermined angles of rotation, and controls the scanning device to scan the worktable at each angle of rotation. A number of sets of points scanned by the scanning device is obtained. A transformation matrix of the sets of points is calculated according to coordinate positions of the labeled points of each set of points. A number of point cloud sets of an object placed on the worktable is obtained by scanning the object at corresponding angles of rotation. The point cloud sets are combined to obtain an overall point cloud according to the transformation matrix, and overlapping points of the overall point cloud are removed.

  • Patent number: 9332588
    Abstract: A method, an apparatus and a system for information transmission are provided. The method includes the following steps. A second user equipment receives update information issued by a wireless access point (AP). The second user equipment is located within a coverage area of the wireless AP. After detecting that the second user equipment has the update information, a first user equipment establishes a connection with the second user equipment and obtains the update information from the second user equipment. A wireless AP of the first user equipment is located outside the coverage area of the wireless AP. In the present invention, the user equipment can update the information without additionally increasing the transmit powers of the wireless AP and the user equipment when located outside the coverage area of the wireless AP, and thus the interference to other equipments is not increased.

  • Patent number: 9230148
    Abstract: Binarization method and system for two dimensional code images is provided. Each block region has a different grayscale threshold. Thus, for each block region, whether a pixel in the block region is determined as black or white restoring process is not solely based on the grayscale value of the pixel itself, but also an average grayscale value of a predetermined area specified for a block region where the pixel locates. That is to say, when the predetermined area in which the block region locates has generally a larger grayscale value, the grayscale threshold corresponding to the block region may become larger, and vice versa. Because the grayscale threshold of a block region is closely related to grayscale values in a background of this block region, external circumstance interference may be prevented from an obtained binary result, producing a clear binary image accordingly.

  • Patent number: 9172909
    Abstract: In one embodiment, video is transmitted between a sending device and a receiving device. The sending device is configured to receive adjacent camera views and encode the adjacent camera views independently into video streams. The sending device performs an image analysis on the adjacent camera views in order to generate a projection matrix to relate the adjacent camera views. The projection matrix and the encoded video streams are sent to at least one receiver. The receiver is configured to receive the encoded video streams and the projection matrix relating the encoded video streams. The receiver calculates an aggregate video stream using the projection matrix. The aggregate video stream includes portions of at least two of the encoded video streams. Other receivers may receive the same encoded video streams and generate a different aggregate video stream having a varying size, resolution, or number of views.

    Abstract: Method and system for decoding a two dimensional code is disclosed. In the binarization process of a two dimensional code image, through performing a dividing operation on the two dimensional code image, each block region has a different grayscale threshold. For each block region, whether a pixel in the block region is determined as black or white is not solely based on the grayscale value of the pixel itself, but also an average grayscale value of a predetermined area set for the block region where the pixel locates. When the predetermined area in which the block region locates has a larger grayscale value as a whole, the grayscale threshold corresponding to the block region may become larger, and vice versa.

  • Patent number: 9087253
    Abstract: Method and system for determining QR code binary image is provided. Locating lines on which edges of the QR code locate are determined according to location information of locating points within the QR code image and distances between the locating points to edges of the QR code. Distances may be used to obtain locating lines on which edges of the QR code locate, with relatively smaller errors. When a QR code image is distorted, it generally bulges outward. The position of a determined locating line is within the interior of the QR code image, and an actual edge of the QR code partly overlaps with the locating line and partly locate on external side of locating line. Edge points on external side of a locating line are detected along the direction of the locating line and then are connected to form an edge line of QR code.
