Abstract
An SOPC-based image acquisition system comprises an image acquisition control part, an image sensor and a PC connected through a USB; and the image acquisition control part, the image sensor and the PC are mutually connected. The image acquisition system is characterized in that the image acquisition control part comprises an on-site programmable logic device FPGAEP2C8Q208C8 and an SRAM image data buffer memory which are mutually connected. Through adoption of an FPGA, not only is cost lowered, but also the problem that blocking is easy in the process of data transmission is solved; seamless transmission of data is achieved; and obtained images are clearer and smoother.
Description
Technical field
The utility model relates to a kind of image capturing system, is specifically related to a kind of based on SOPC image capturing system.
Background technology
Relatively conventional dsp processor asynchronous communication a few days ago, the mode of this asynchronous communication is easily blocked in data transmission procedure, also clear and smooth not while processing image.
Summary of the invention
It is a kind of based on SOPC image capturing system that the utility model provides, and utilizes FPGA not only to reduce cost but also solved the problem of easily blocking in data transmission procedure, realized the seamless transmission of data, also clear and smooth more of the image obtaining.
Technical solution of the present utility model is:
A kind of based on SOPC image capturing system, comprise interconnective IMAQ control section, imageing sensor, and the PC connecting by USB, its special character is: described IMAQ control section comprises field programmable logic device FPGAEP2C8Q208C8 and the SRAM view data buffer memory of interconnection.
Above-mentioned SRAM view data buffer memory is IS6l LV25616; Described USB is EZ-USB.
Above-mentioned imageing sensor gathers image by optical mirror slip.
The utility model has the advantage of: utilize the FPGA not only to have reduced cost but also solved the problem of easily blocking in data transmission procedure, having realized the seamless transmission of data, also clear and smooth more of the image obtaining.
Accompanying drawing explanation
Fig. 1 is the utility model structural principle block diagram.
Embodiment
Referring to Fig. 1, a kind of based on SOPC image capturing system, comprise interconnective IMAQ control section, imageing sensor, and the PC connecting by USB, IMAQ control section comprises field programmable logic device FPGAEP2C8Q208C8 and the SRAM view data buffer memory of interconnection.SRAM view data buffer memory is IS6l LV25616; Described USB is EZ-USB.Imageing sensor gathers image by optical mirror slip.
The utility model utilizes FPGA and USB2.O that upper camera (Ov7660) optical mirror slip view data is passed to PC, use USB2.O (that select here is EZ-USB FX2) controller from FIF0 (Slave FIF0) pattern, by embedding Ni-osII processor, in FPGA, produce corresponding control signal, realize the fast reading and writing to data.This scheme transmission speed is fast, data are accurate, can expand to other and need to be undertaken by USB the system of rapid data transmission.Compared with other adopt asynchronous communication scheme, utilize NiosII to process the corresponding control signal of generation the view data collecting is carried out to cushioning effect, make data without losing transmission, the data that obtain at host computer clear and smooth more.
