A method and device for extracting image and video data from a vehicle-mounted microcomputer

Abstract

The invention discloses a method and a device for extracting vehicle-bone microcomputer image video data. A system is separated into three modules according to the functions, an image acquisition module is used as a first module, wherein a vehicle-bone microcomputer video image is acquired through a high definition network camera at certain acquisition frequency, and the acquired image is locally stored; an image identification module is used as a second module, wherein figures and scales of bar graphs on the image which is obtained from the camera are identified through an image identification algorithm, and are locally stored temporarily according to the data presented specific meaning; and a data transmission module is used as a third module, the identified and analyzed data organization is transferred to a data analytical platform in a message format according to a data transmission protocol (transmission control protocol (TCP) / internet protocol (IP)), so that the data transmission protocol can carry out data editing and post-processing. The method and the device are used for solving the problem in the prior art that the data from an S485 interface of a monitoring screen cannot be directly read.

Description

technical field [0001] The invention relates to a method and device for extracting image and video data, in particular to a method and device for extracting image and video data of a vehicle-mounted microcomputer. Background technique [0002] In order to monitor the running status of the harmonious locomotive on the test bench in real time, it is necessary to read the main data indicators of the harmonious locomotive operation, organize them in a certain way, and transmit them to related software for data processing and analysis. However, the current technology cannot directly read data from the RS485 interface of the monitoring screen, that is, the image of the monitoring screen cannot be transmitted to the image processing system for processing and analysis, that is to say, the operating indicators of the locomotive cannot be grasped, let alone these Indicators are analyzed, processed and utilized. [0003] Based on the current situation, we need to record the data of th...
