Transplantation Of Linux Operation System And Software Designing On Machine Vision Platform Based On6467T

Machine vision systems use image sensors with high performance to extend humanperception and use the powerful computing ability of computers to reduce repeated,cumbersome human labor. Therefore, it’s playing a more and more critical role in modernindustry.Linux is an open-source, free, transplantable real-time operation system. It has a widerange of applications in the embedded system area, such as consumer electronics andindustrial control. So the researching of transplantation of Linux to the DM6467T systemand software designing on it is of practical value. This paper introduces an embeddedmachine vision system based on TI DM6467T digital signal processor and mainlyimplements the following work:Transplantation of Linux to the ARM CPU of DM6467T SoC; Tailored the Linuxkernel into1.9MB. When idle the operation system only occupies0.3%of the CPUcalculation ability. The system can startup quickly with only35MB memory.Implemented Real-time Clock and USB mouse device drivers; designed experiment totest the the two drivers above; tested the TCP/IP support for communication of Linux. Theexperiments showed the system run well.In order to assess the performance and prepare for further development, transplanteducGUI and OpenCV1.0to the Linux system; built a GUI interface and applied OpenCValgorithms calling; tested and applied several image preprocessing algorithms on the system.
