A method of transmission and monitoring in local area network (LAN) for the welding seam video
information of binocular vision welding robot is proposed. This paper uses MPEG-4 video CODEC functions
of DivX, video for Windows (VFW) video capture technology, multi-threaded network communication idea and
WinSock Socket in Visual C++ 6.0. In the end, client/server (C/S) communication model based on TCP/IP
protocol has been developed. Experimental results show that the method can achieve the multiple welding seam
video’s real-time transmission in LAN. Moreover, the Canny operator is used to realize the edge feature extraction
of the seam image which is captured by the client, so that the edge of the seam extracted is continuous and clear.
