Abstract: A method and system for networking of spliced building blocks, and the spliced building blocks applicable to wireless networking are provided.

Abstract: A programming building block includes an instruction reading building block and an instruction building block. The instruction reading building block reads command instructions in the instruction building block. The command instructions include an instruction for setting a mode, an instruction for setting a behavior in the mode, an instruction for setting a behavior, or an upgrade instruction. A priority is set between the plurality of instructions for setting the mode. Compared with the prior art, the present invention has the advantage that programming can be performed without an electronic display device.

Abstract: A method for determining a complete icon includes: acquiring an image, and delineating determination regions in a peripheral region of the image; scanning and counting a number of pixels of a first color corresponding to an icon in the whole image and a number of pixels of a second color corresponding to an auxiliary identifier in each determination region; determining, if the number of pixels of the first color is less than or equal to a first threshold, or the number of pixels of the second color in one or more determination regions is less than or equal to a second threshold, that the icon is incomplete; and determining, if the number of pixels of the first color is greater than the first threshold, and the number of pixels of the second color in each of the determination regions is greater than the second threshold, that the icon is complete.

Abstract: The present disclosure relates to a visual servoing method based on fusion of distance space and image feature space.

Abstract: Provided is a method and system for uniform execution of feature extraction. The method comprises: acquiring a feature extraction script for defining a processing logic related to feature extraction; analyzing the feature extraction script to generate an execution plan for feature extraction; and executing the generated execution plan by a local machine or a cluster based on a feature extraction scene. Based on the method and system, feature extraction can be uniformly executed at various feature extraction scenes.
