Problems solved by technology

[0003] In the prior art, software logs are often used to record the running status of the program. The disadvantage is that it is difficult to record the overall and complete records, making it difficult to find the cause of the initial failure; and if the complete records are recorded in the form of data packets, the monitoring data will be obtained. The amount of data is too large, there are defects in data storage and transmission difficulties, complex playback methods, and difficulty in complete reproduction

Embodiment 1

[0127] On the first hand, if figure 1 As shown, the present application relates to a data processing method, comprising the following steps:

[0128] Step S1, obtaining a real-time data stream, the real-time data stream includes at least one type of monitoring data;

[0129] Step S2, streamlining the real-time data stream in units of time slices, generating differential frames or key frames based on preset rule processing, and saving the processed real-time data stream as a historical data stream; wherein, the The difference frame stores at least one type of monitoring data; the key frame stores each type of monitoring data in the real-time data stream.

[0130] It can be seen from the technical solution of the first aspect above that the real-time data stream obtained in the present application globally saves the monitoring data continuously obtained by the mobile platform, which facilitates the formation of global intuitive analysis. This application adopts time slice and ...

specific Embodiment approach

[0170] As a specific implementation, it also includes the following steps:

[0171] Responding to a trigger condition, acquiring detailed data under the trigger condition;

[0172] storing said detail data and a key time stamp at which said detail data was generated;

[0173] Send the stated key timestamp.

[0174] The triggering condition may be a preset triggering condition in the movable platform, and the preset triggering condition includes sensing a dynamic change of the external environment or an abnormal internal operation.

[0175] The detailed data may be, for example, maps, images, laser point clouds and other complex data with large data storage capacity. The detailed data is stored according to the corresponding key time stamp.

[0176] More specifically, the control program is preset in the mobile platform, and detailed data is obtained to record the unexpected situation at that time, so as to help trace the source of the fault event. When the mobile platform ...

Embodiment 2

[0190] Second aspect, such as figure 2 As shown, the present application also relates to a playback data acquisition method, comprising the following steps:

[0191] In response to the playback request, the playback request includes the playback start time, and the historical data stream from the playback start time is loaded; wherein, the historical data stream is simplified by the real-time data stream in units of time slices processed, and saved based on the difference frame and key frame generated by preset rule processing; the difference frame saves at least one type of the monitoring data; the key frame saves the real-time data stream Monitoring data described in each category;

[0192] Analyzing the difference frame in the loaded historical data stream; wherein, the parsed difference frame saves the monitoring data of each type in the real-time data stream.

[0193] The playback request is a playback request obtained by receiving the user operation after the user ope...

Abstract

The invention relates to a data processing method and device, a playback data acquisition method and device and a mobile platform, and the data processing method comprises the following steps: obtaining a real-time data stream which comprises at least one type of monitoring data; carrying out simplification processing on the real-time data stream by taking a time slice as a unit, processing based on a preset rule to generate a difference frame or a key frame, and storing the difference frame or the key frame as a historical data stream, wherein the difference frame stores at least one type of monitoring data; and enabling the key frame to store each type of monitoring data in the real-time data stream. The invention provides a scheme for carrying out global and complete recording on monitoring data, and simultaneously realizes data simplification to optimize playback and complete reproduction data processing and playback data acquisition methods and devices, and a mobile platform.

Description

technical field [0001] The present application relates to the technical field of artificial intelligence, and in particular to a data processing and playback data acquisition method and device, and a mobile platform. Background technique [0002] The mobile platform will face the dynamic changes of the external environment and the influence of internal factors in the long-term operation. For example: Encountering dynamic pedestrians, vehicles, temporarily stacked goods, partial reconstruction and occlusion of buildings, etc., sudden software and hardware failures, abnormal decision-making perception and other problems, resulting in abnormal operation, deviation from the line, collisions, etc. It is difficult to detect or predict before the operation of the movable platform, and it will appear irregularly even after a long period of stable operation. [0003] In the prior art, software logs are often used to record the running status of the program. The disadvantage is that ...
