Corner connection optimization method and system for two-dimensional picture wall

The invention discloses a wall corner connection optimization method and system for a two-dimensional picture wall, and the method comprises the steps: scanning wall corner points of a preset room model, and obtaining a wall corner point information set; wherein the wall corner point information set comprises an associated wall of each wall corner point; according to the number of associated walls of the wall corner points, a trapezoidal wall and a rectangular wall are drawn in combination with the wall corner point information set; and optimizing the room model according to the trapezoidal wall and the rectangular wall. The wall corner points are classified according to the number of the connecting walls of the wall corner points, different wall drawing methods are used for the wall corner points with the large number of the connecting walls and the wall corner points with the small number of the connecting walls, the situation of wall corner puncture is avoided, and the wall corner connecting effect and the
