Abstract

The invention discloses a SoC_FPGA-based flexible intelligent machine vision detection system. A SoC_FPGA serves as a central processing unit, and the SoC_FPGA is integrated with a power module, a clock module, an image sensor, a storage system, a power monitor, an I/O, and a transmission module. The SoC_FPGA comprises an HPS and an FPGA, and is integrated with an ARM hard core processor, a DSP and an FPGA. A programmable logic and a DRAM controller in the FPGA architecture form an image acquisition module used for acquiring and storing images. The programmable logic, a DSP module and an RAM module in the FPGA architecture form a custom accelerator used for image processing operation. The ARM hard core processor is loaded with an embedded operating system and a user program to manage hardware resources of the system. The machine vision detection system achieves high degree of integration and low cost.

Description

technical field [0001] The invention belongs to the technical field of machine vision, in particular to a SoC_FPGA-based flexible intelligent machine vision detection system. Background technique [0002] The machine vision system converts the target into an image signal through the image capture device, and performs various operations on these signals to extract the characteristics of the target, and then controls the on-site equipment action according to the result of the discrimination. In the traditional mass production process, the detection of product quality mainly relies on artificial vision, but artificial vision has low efficiency and low precision. The use of machine vision detection methods can greatly improve production efficiency and production automation. [0003] Because the machine vision system involves massive data and complex calculations, the traditional machine vision system usually adopts the design mode of separation of acquisition and analysis. A typ...
