Abstract: Systems and methods are provided to improve the success rate of relocalization and eliminate the ambiguity of false relocalization by exploiting motions of the sensor system. During a relocalization process, a snapshot is taken using one or more visual sensors(110) and a single-shot relocalization in a visual map is implemented to establish candidate hypotheses. The visual sensors(110) move in the environment, with a movement trajectory tracked, to capture visual representations of the environment in one or more new poses. As the visual sensors(110) move, the relocalization system(100) tracks various estimated localization hypotheses and removes false ones until one winning hypothesis. Once the process is finished, the relocalization system(100) outputs a localization result with respect to the visual map.

Abstract: Disclosed are a block generation method and apparatus, a computer device and a storage medium. The method comprises: a first node acquiring average network delay and the maximum network delay between the first node and a second node (S101); the first node determining, according to the average network delay, an average system time difference between the first node and the second node (S102); the first node receiving a block generated by the second node, and determining a local timestamp when receiving the block, wherein the block carries a timestamp (S103); and the first node determining, according to the average network delay, the maximum network delay, the average system time difference, the local timestamp, and the timestamp carried in the block, whether the block is a block generated by the second node at a block time that satisfies a pre-set time requirement (S104). The solution solves the technical problem in the prior art of the accuracy rate of determination of rationality of block time being low, and achieves the technical effects of effectively improving the accuracy rate of the determination of the rationality of the block time, and improving block generation efficiency.
