Research And Design Of Image Acquisition And Compression Coding Based On OMAP3530Processor

With the rapid development of embedded technology and image processing technology, theembedded image processing products has widely been used in daily life and industrial production.Such as in the field of modern security, embedded products because of its own characteristics arewidely used to protect property and life safety of the users. As well as in the field of industrialcontrol, embedded image monitoring system is an effective approach of obtaining the siteinformation.This system is based on the OMAP3530-EVM development board, embedded Linuxoperating system and OV3640camera. It designs and implements an on-site image informationacquisition and compression coding system. It has the capabilities of collecting and storing thescene picture information. OMAP3530is a TI’s processor. It includes ARM Cortex-A8andTMS320C64x DSP dual-core processor. Cortex-A8core owns the strong ability to control, whileDSP has the powerful computing capability. The Linux operating system open its’ source, its’hardware and software can be cropped. OV3640, as the image collection terminal of this subject,has high performance features. It is the peripherals multimedia comes from OMAP3530-EVMplate. In the volume and power consumption, the image acquisition system based on embeddedplatforms has significant advantages to the traditional image acquisition system. It has broadapplication prospects in terms of modern security and industrial monitoring.Based on the OMAP3530-EVM platform, this thesis gives the detailed design process ofimage information acquisition and image compression coding system. Firstly, it gives theanalysis of the embedded foundation architecture and OMAP3530-EVM development board.Secondly, it introduces the process of building the environment of cross-compiler. Next, itcompletes the design of image information collection subsystem and image compression codingsubsystem. Finally, it accomplishes the procedure of debugging the entire system and obtainingexperimental results.
