Method, system and equipment for determining selfing point of small-line-segment knife compensation interference

The invention discloses a method, a system and equipment for determining a selfing point of small-line-segment knife compensation interference. According to the invention, a first intersection area formed by a first line segment and a third line segment, and a second intersection area formed by a second line segment and a third line segment are determined according to the preset algorithm, so that a first boundary point and a second boundary point are obtained; based on the first boundary point, the second boundary point and a preset algorithm, a processing start point and a processing end point are determined, and based on the processing start point and the processing end point, a self-intersection point is determined to execute preset cutter compensation interference self-intersection point processing operation. According to the method, the self-intersection point of the line segment can be determined in the process of processing the small-line-segment cutter compensation data, the accuracy of positioning t
