Studies On Acquisition And Processing Of Laser Line Image Based On WinCE

With the rapid development of current technology, a wide range of robot vision applications unprecedented, involving almost all areas of human activity. Robot vision system includes an image acquisition module and image processing module.The task is to design and implement image acquisition and processing modules of autonomous mobile robot vision system.Design and implementation of image acquisition and processing modules can not do without the support of hardware and software. Hardware platform is composed of four parts which are image sensor, line laser, processing chip based on ARM7 v and peripheral equipment. The image sensor selects a Mini CCD Camera. The line laser chooses a word line laser red semiconductor laser. The main processor selects AM3517 based on core of Cortex_A8. Peripheral hardware have some blocks, like TVP5146--digital video decoder chip, interface used to input or output video, LCD and its interface, serial communication interface etc. Windows CE operating system is chose as software platform. The operating system is customized by Platform Builder for CE 6.0 which is one of the tools in VS2005 environment. Image acquisition and image processing is implemented by Visual C ++ programming language in VS2005 environment. Image acquisition is based on Windows CE operating system Direct Show technology. Image processing's details include gray processing, smoothing and binarization etc.The image acquisition and processing modules are tested after encapsulated into the autonomous mobile robot in laboratory. Experiments show that this module is able to achieve image acquisition and processing functions.
