    Abstract: A calibration system for a multi-camera system is disclosed. The calibration system includes a connection device, a storage device, and a processor. The processor is configured to control each camera of the multi-camera system to capture a calibration image of a calibration board having a pattern including multiple conventional features and at least one non-conventional feature in which an FOV of the calibration image of at least one camera does not contain at least one conventional feature of the pattern, detect the conventional features and the non-conventional feature in the calibration image and record positions thereof in the storage device, transform a position of each conventional feature into absolute coordinates relative to reference coordinates by using a position of the non-conventional feature as the reference coordinates, and according to the absolute coordinates of the transformed conventional features, match the conventional features in the calibration images captured by the cameras to calibrate the cameras.

    Abstract: A data processing method includes the following steps. An input image is received, the input image has a plurality of pixels, and each of the pixels has a pixel position. An valid region is defined in the input image, a plurality of valid pixels among the pixels are located in the valid region, and each valid pixel has a valid data. The valid data is written to the target address of the memory correspondingly according to a starting write address of the memory and a valid width of the input image, or according to the starting write address, the starting offset of the input image and the accumulation address of the memory.

    Abstract: A processing system for reducing data amount of a point cloud includes a sample rate controller and a transmitter. The sample rate controller is used for receiving a plurality of coordinates corresponding to the point cloud, and sampling the plurality of coordinates according to an adjustable sampling rate to generate a plurality of sampled coordinates, wherein data amount of the plurality of coordinates is not less than data amount of the plurality of sampled coordinates. The transmitter coupled to the sample rate controller is used for outputting the plurality of sampled coordinates.

    Abstract: A fusion method and a fusion system for multiple depth information are provided. A first depth information is obtained by a first image capturing module. A second depth information is obtained by a second image capturing module. Through a non-linear transformation, the first depth information is transformed into a first transformation information, and the second depth information is processed according to the first transformation information to generate a transformed information; or the first depth information and the second depth information are merged to be a fusion information, which is then transformed into the transformed information through the nonlinear transformation.
