Video front-end intelligent monitoring system and method, computer equipment and terminal

The invention belongs to the technical field of video monitoring, and discloses a video front-end intelligent monitoring system and method, computer equipment and a terminal. A main processor is responsible for realizing a system image data interface, an external communication interface, image preprocessing and system management; the coprocessor is used for being responsible for convolutional neural network algorithm reasoning calculation, and a calculation result is transmitted back to the main processor through an in-board communication interface; the power subsystem is used for supplying power to the whole system; the storage subsystem comprises a nonvolatile memory, an on-chip cache and an off-chip dynamic memory; the clock subsystem adopts an active crystal oscillator to provide clock sources required by the subsystems; and data communication interfaces are enriched to realize system video data input and output, control instruction input and output and data interconnection between the main processor and
