Set Up

A model of wireless network data interchange was built to solve cross-platform exchange data in intelligent robot. In the framework of embedded Soft-PLC - Codesys real-time operating system, we apply Socket network programming technology based on TCP/IP communication protocol to set up a physical channel between VC++ platform and the Codesys platform. It realizes the real-time data exchange between host-computer and slave-computer uploaded embedded operation system of robot. A special multi-threaded processing class was developed to enhance the multi-tasking allocation ability of the system. Exchanged data was packaged and analyzed to ensure the accuracy of transmitted data. The experiment shows built communication system platform is justifiable, and data transmission speed is less than 10ms. It is able to meet the needs of real-time control in intelligent robot.

Edge detection that is an important means to realize image segmentation has important application significance in image processing, industrial detection, artificial intelligence and the target recognition field. As the demand for real-time and rapidity in image processing, the embedded image processing technology has been widely applied. But the realization of real-time edge detection for image requires a large amount of data processing, limited system resources of embedded system is the main reason of the embedded image processing technology development. In order to shorten time embedded systems edge detection processing large amounts of data, based on adaptive threshold Canny algorithm, this paper as the FPGA data processing DSP chips and made a FPGA + DSP hardware architecture, effectively improve the system real-time, get a good edge detection results.

The real-time image-processing by SOPC technology on the hardware is the new direction of the image-processing technology. FPGA is the core component of the image-processing based on SOPC technology. The principles and characteristics of SOPC technology and the commonly image-processing algorithm are introduced in the first part. Then the traditional DSP image-processing technology is compared with the image-processing technology using FPGA chip embedding with the Nios II soft-core processor. As a result, a conclusion that the usage of the SOPC technology can increase the speed and working frequency of image-processing is derived. At last, the application status of SOPC technology used in image-processing is introduced. It can be concluded that the SOPC technology in real-time image-processing have the broad application prospect.

Image Processing Technology

Corporation work piece length measure system based on digital image processing technology. CCD vidicon is used as the image capture equipment. Image signal are converted into 8 bits digital code stream by CMOS image sensor chip OV9650. DSP chip of TI is used as the core of image processing in the scheme. Peripheral SDRAM are expanded through peripheral bus to save the large amounts of temporary data in data processing to reduce the time for image processing. Median filtering is adopted in image enhance of the object image. The length of rectangle work piece can be measured in the distance by untouched way by improved edge recognition algorithm in real time. The measurement result is displayed by LCD. Meanwhile the measure system communicates with PC through communication interface. It has been proved that the system can guarantee real-time and high accurate. It’s a typical instance of DSP and digital image processing technology used in industry.
