Problems solved by technology

However, as the resolution and frame rate of image sensor output images continue to increase, the number of image sensor output signals is increasing, which has an impact on core parameters such as the operating frequency of the selected coprocessor, the number of logic units, and the number of pins. The high requirements also mean that the selection of coprocessors under the current solution is very limited

Embodiment Construction

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0034] see figure 1 , figure 1 It is a schematic flow chart of a video data processing method in the prior art. The central processor sends the main control signal to the coprocessor through the low-speed communication interface, and the coprocessor is connected to the auxiliary equipment through the auxiliary equipment control interface. After receiving the main control signal, the coprocessor generates a control signal and sends it to the image sensor. fig...

Abstract

The invention discloses a video data processing method and device and a computer readable storage medium. The method comprises the steps that a coprocessor obtains sub-image data of one channel in a current frame of image copied by a signal copier; and the coprocessor determines the type of the current frame of image according to the sub-image data, and sends the type to a central processing unit, and the central processing unit classifies and processes the received current frame of image according to the type. Through the design mode, the advantage of multi-shutter snapshot can be maintained, the performance requirement on the coprocessor can be greatly reduced, and the time sequence correlation between the synchronization information output to an image sensor and the video data collected by the central processing unit can be strong.

Description

technical field [0001] The present application relates to the technical field of intelligent transportation, in particular to a video data processing method, device and computer-readable storage medium. Background technique [0002] In the field of intelligent transportation, the currently commonly used capture scheme is called a double-shutter or triple-shutter capture scheme. 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. The coprocessor collects the image data output by the image sensor, adds the current image shutter mode information and snapshot information at the set position, and outputs it to the central...
