PURPOSE:To attain the accurate connection of a core line by deciding the validity of the core line vector having its interruption points of both ends included in the searching areas of the interruption points, reforming a loop after excluding the interruption points of the core line vector to be neglected and obtaining the connecting points based on the loop to carry out the connection of the core line. CONSTITUTION:The short core line vectors AD and CB exist at an intersecting point, a loop of E C H D G F A is formed. Then the loop is detected again after excluding the interruption points (A-D) out of the process subjects and a loop of E F G H is formed. When the loops A B C and D E F don't share the same core line vector and are independent of each other, both loops are connected to each other based on the connecting points X and Y. If the different loops include the interruption points at both ends of the same core line vector, the distance between the connecting points X and Y is obtained for decision of the distance value in order to decide both interruption points. Then both loops are detected again and connected together after obtaining a connecting point. As a result, the accuracy is improved at the connection part of a core line. |
