Abstract

The invention relates to a video data processing method and device, and the method comprises the steps that a coprocessor generates a control signal and transmits the control signal to an image sensor; wherein the control signal at least comprises an exposure parameter, a gain parameter and a classification identifier; the image sensor collects image data according to the control signal, configures a corresponding classification identifier for the image data, and sends the image data including the classification identifier to a processor; and the processor receives the image data, and classifies and processes the image data according to the classification identifier of the image data. By means of the image shutter data classification method and device, the problem that the FPGA is adopted to assist in image shutter data classification, and the requirement for model selection of the FPGA is high is solved, and the effect that image shutter data classification can be achieved through a common FPGA is achieved.

Description

technical field [0001] This application relates to the field of intelligent transportation, in particular to a video data processing method and device. Background technique [0002] In the field of intelligent transportation, the currently commonly used capture schemes are double-shutter or triple-shutter capture schemes. Different image shutter modes are used to collect image data of different qualities according to actual needs. For example: video shutter mode data is used for ordinary video surveillance; snapshot shutter mode data is used for illegal evidence collection; image shutter mode data is used for vehicle identification and tracking. Therefore, it is necessary to classify the image data collected by the image sensor. In the existing capture scheme, the timing is controlled by the FPGA output, and the image sensor is controlled to output image data. At the same time, the FPGA collects the image data output by the sensor, superimposes the snapshot information in...
