Abstract: This disclosure discloses a method and apparatus for monitoring a message transmission frequency in a robot operating system. A specific implementation of the method includes: writing to-be-transmitted messages, into a pre-allocated memory; obtaining time points when the to-be-transmitted messages are written into the memory, and recording the time points in a preset time point list; determining a message transmission frequency within a preset time interval based on the time points in the time point list; and comparing the message transmission frequency with a preset message transmission frequency threshold, and generating monitoring information based on a comparing result. This implementation monitors the message transmission frequency of a process to thereby avoid information codes related to monitoring of each application from being added to the application so as to reduce the program debugging cost, and improve the monitoring efficiency.

Abstract: The present application discloses a method and an apparatus for processing point cloud data. The method of an embodiment comprises: recognizing an object in a to-be-labeled point cloud frame by using an obstacle recognition algorithm, to obtain a recognition result; presenting the recognition result as an initial labeling result of the point cloud frame; and updating the labeling result in response to a correction operation by a user on the labeling result. According to the embodiment, the speed and accuracy of point cloud data labeling are improved.

Abstract: This disclosure discloses a method and apparatus for monitoring a robot operating system. The method in an embodiment includes: obtaining process identities of to-be-monitored nodes in a group of to-be-monitored nodes; inquiring about state information of processes corresponding to the process identities; determining whether the to-be-monitored nodes are operating normally, based on the state information of the processes; and outputting information that the group of to-be-monitored nodes is abnormal, in response to a number of normally operating to-be-monitored nodes in the group of to-be-monitored nodes being below a predetermined threshold. In this embodiment, the nodes are monitored in groups to improve the efficiency of maintaining the robot operating system.

Abstract: This disclosures discloses a method and apparatus for acquiring data in a robot operating system. A specific implementation of the method includes: monitoring in real time a data storage area of an information acquirer, the information acquirer configured to acquire location state data of a driverless vehicle; obtaining updated data if the updated data are present in the data storage area; and storing the updated data into a data buffer corresponding to the information acquirer. The implementation improves the robustness of the data.
