Abstract: Method and apparatus for detecting obstacle based on monocular camera are provided. The method includes: obtaining a target frame image and its adjacent frame image shot by the monocular camera; deleting an unstable feature point from an initial feature point set of the adjacent frame image to obtain a preferred feature point set; dividing a target feature point set to obtain several target feature point subsets; judging whether the target feature point subset corresponds to obstacle based on a change of a distance between points within a ground projection point set of the target feature point subset from adjacent frame time instant to target frame time instant; and determining a union of all the target feature point subsets which are judged as corresponding to obstacles as an obstacle point set of the target frame image.

Abstract: A method for detecting a generalized passerby includes: acquiring an input image; determining whether a preset common feature of a wheel exists in the input image; selecting an image window at left side or right side or upper side of a center of a region where the preset common feature of the wheel is located in a case that the preset common feature of the wheel exists in the input image; inputting the selected image window into a preset upper-body classifier; detecting whether an upper body of a passerby exists in the selected image window and outputting a first detection result.

Abstract: The present invention relates to a remote operation receiving system, for suppressing the generation of the executive results of the action which don't meet the operating aim. The host unit of a local server may enable a target equipment to perform the corresponding action according to a remote operation instruction received from a remote operating device (S400). Based on the history data, the condition variation in the target equipment generated between the operation reference timing to the current timing is detected (S320˜S345). The operation reference timing refers to the time point when the condition displayed on the screen in a distant device is monitored from the monitoring device when the distant operating device is operated. If the condition variation is relatively large, then the remote operation instruction is abandoned (S430), and if smaller, then the target equipment performs the action to which the remote operation instruction corresponds (S400).

Abstract: The present invention provides a method for data linkage driven by an event, used for data interaction between a first platform and a second platform. The second platform stores shared information and the method comprises: determining which platform the received event is from; forwarding a data packet from the second platform to the first platform for logical operation processing when the received event is from the second platform; when the received event is information from the first platform that at least includes a shared information operation instruction resulting from logic operation processing of data packets in the first platform, returning a shared information operation instruction completion message to the first platform, meanwhile forwarding the shared information operation instruction to the second platform so as to complete the shared information operation on the second platform. Therefore, the first platform acquires data synchronously without waiting for feedback of the second platform.

Abstract: An event detection method in a distributed environment includes, when a non-parsable event occurred during grammar parsing, executing the following process until the first grammar parser module obtains a detection result, including the event that the current grammar parser module can not parse in a scheduling request as a next event to be detected and sending it to the grammar control module, scheduling, by the grammar control module, other grammar parser module as the target grammar parser module for further parsing based on the scheduling strategy table, performing grammar parsing based on the local parsing table in the scheduled target grammar parser module, returning parsing results to the grammar control module for further parsing when no non-parsable event is found; or repeating the above process with the target grammar parser module as a new current grammar parser module when an non-parsable event is found.

Abstract: The embodiments of the present invention disclose an event detection method and device. The method includes: predefining event-based detection rules with a predicative context-free grammar; generating by parsing the detection rules a parsing table of pushdown automaton which supports parallel parsing; receiving an event to be detected; and analyzing by a controller the event to be detected according to the parsing table, to obtain a detection result. The present invention is especially applicable to detection of network attack events. The embodiments of the present invention detect the attacks with a predicative context-free grammar on the basis of events, and ensure a close combination of a protocol parsing process and an attack detection process, as well as a close combination of multiple attack detection rules, thus decreasing unnecessary calculations.
