Summary:The invention relates to a gridding calibration method for a channel protection area of an overhead transmission line, and the method comprises the following steps: (1), carrying out the field debugging and downloading a monitoring and photographing picture when visual monitoring and photographing equipment is installed; (2) plotting a projection line of a lead cross arm on the ground; (3) positioning right below the lead on site, and then connecting a ground projection endpoint of a lead cross arm with a positioning point to form a lead projection line; (4) drawing a line of the lead protection area; (5) finally marking the protection area and the ground projection line of the lead on the system picture; and (6) measuring the actual distance according to a grid scale by plotting a distance judgment line, judging the level of the hidden danger and obtaining accurate data so as to obtain line abnormity and alarm information. According to the invention, the timeliness and efficiency of eliminating potential saf
