1. draw the processing method that real-time video warning line is anti-aliasing, it comprises the following steps:

  • 1) arrange one and comprise the anti-aliasing treatment facility of the drafting real-time video warning line of camera, COM port, central processing unit, I/O module, memory and Video Monitoring Terminal;

    2) by original warning line data, camera collection to warning line data input in central processing unit by I/O module, original warning line information to be processed will be needed in central processing unit to send into based on apart from anti-aliasing module with based on the anti-aliasing module of area, enter step 3 respectively) and step

         4);

    3) based on apart from anti-aliasing module, all warning line data received are adjusted according to the grey level of desirable straight line and each pixel distance;

    4) based on the anti-aliasing module of area, all warning line data received are carried out grey level adjustment according to the weighted area that desirable straight line rectangular area is crossing with each pixel;

    5) through step

         2) and step

         3) process after warning line data input in data fusion module, data fusion module compares based on apart from anti-aliasing module with based on the data that the anti-aliasing module of area exports and Weighted Fusion, and completes the anti-aliasing process of warning line data.
