Research On Wireless Video Transmission And Control Technology

This system effectively combines with the wireless video transmission and display control technology to meet intelligent man-machine interactive requirements, and provides an effective measurement technology of artillery axis.Firstly CCD camera sends the captured target images to the receiver through the wireless transmission module,the receiver processes the received analog video signal through amplifying and decoding circuits to get digital video images, then the digital video signal will be processed further by ARM microprocessor, eventually display screen of OLED will display the processed video signal. We will control the image window of cross line to enlarge or reduce and shift by the buttons or touch screen, to make it overlap with target image of cross line.we calculate the relative offset of the target image and the center of origin to get the information of artillery axis deviation. At the same time,we transmit video image to PC through USB2.0interface to achieve the requirements of the automatic control.
