Method for processing pen breaks in spliced wall multi-person labeling system

The invention discloses a method for processing pen breaks in a spliced wall multi-person labeling system, which comprises the following steps: finding out lines needing to be connected by a splicing joint by finding out points closes to the splicing joint and the drawing time of a line of the points; and realizing the splicing joint connection by finding out the last point of the to-be-connected line close to the current splicing joint and assigning the coordinate value of the last point to the coordinate of the first point of a currently and newly created line. The method supports the processing of pen breaks generated during the synchronous labeling, writing and drawing of a plurality of people in a large-screen wall-splicing system, solves the problems of pen breaks, jumps and discontinuous drawing tracks in the prior spliced wall positioning technology, improves the positioning accuracy at the splicing joint of display units of the spliced wall, and correspondingly improves the touch positioning accuracy of the prior spliced wall positioning system.
