A video image acquisition system based on S3C6410 is designed. S3C6410 camera interface characteristic is analyzed, and the development of video image acquisition drive method in WinCE 6.0 environment is described. Using TVP5150 decoding chip converts dual-band CCD camera analog video signal into digital video signal of S3C6410 camera module identification, and which is displayed on the LCD. This...
This paper realizes a SoPC system which balances an electric unicycle based on image data from a CMOS camera. Generally, tilt-meters and gyros have commonly been chosen to measure the tilt angle and angle rate of a unicycle. In this paper, a CMOS camera is employed as the tilt angle measurement sensor instead. Through simple image processing techniques, a hardware circuit module for inclination measurement...
In view of the current situation of the less embedded Linux image acquisition application based on V4L2(Video for Linux Two), embedded image acquisition system based on V4L2 is designed. S3C6410 is adopted as hardware development platform and Linux as software platform. After loading the driver of CMOS camera OV9650 and other relative drivers, image acquisition applications on the basis of V4L2 is...
Selective change-driven (SCD) vision is a capture/processing strategy especially suited for vision systems with limited resources and/or vision applications with real-time constraints. SCD vision capture essentially involves delivering only the pixels that have undergone the greatest change in illumination since the last time they were read-out. SCD vision processing involves processing a limited...
Embedded 32 bits multimedia micro-processor SPCE3200 designed by Sunplus company is used as controller and CMOS image sensor chip OV7720 is used for image acquisition by the system. The use of the eCos Configuration Tool of Embedded Configurable Operating System can configure the driver's attributes of CSI & OV7720. The camera equipment can be controlled and configured by the POSIX standard file...
This article introduces the video signal processing system which is widely used in language room. The system core is embedded processor included internal-integration hardware encoder. Video data in the case of VGA (640*480) @25fps can be encoded in real-time and uploaded to PC. Since the operating system Windows CE in the system adopts friendly operating interface and familiar application environment,...
A configurable, record capacity extensible and nonuniformity reducible of high speed camera is designed in this paper. The CMOS image sensor lupa-300 which is produced by Cypress Corporation is used for the system. There is nonuniformity existed in the sensor. The two point method of the image with real time correction algorithm has applied to process the image nonuniformity. Then the corrected image...
In order to acquire high speed real-time astronomical image data and recognize the object planets, a kind of system based on FPGA and PCI bus is presented. In this system, logic design including Camera Link data interface, digital image data capture and data transmission to PC through PCI bus is completed in FPGA (Xilinx Virtex 4); and the final results can be verified in PC. The system can collect...
With the advance of image processing techniques and the fast reduction of image sensor costs, embedded computer vision is becoming a reality. This paper presents the design and implementation of an integrated CMOS imaging system based on DM642. The system can acquire VGA resolution image at 100 frame/s. The on-board 10 Mbps Ethernet connection and the UART as well as digital I/O ports provide convenience...
