发明名称 DEVICE FOR DETECTING ISLAND POSITION OF SINGLE CRYSTAL INGOT GROWING FURNACE AND METHOD FOR DETECTING ISLAND POSITION
摘要 The present invention provides the device for detecting an island position of an ingot growing furnace, comprising a control means for detecting the position of an island by analyzing the image obtained by the photographing means, wherein the control means derives a plurality of singularities with respect to the temperature or brightness from the image, derives a plurality of connection lines respectively forming straight lines by the mutual connection of a series of the singularities, considers an area in which the most intersections are generated as an island among areas in which the plurality of connection lines intersect each other, and determines whether the island is positioned in a seed contact area in which the seed is set to be lowered.

主权项 1. A device for detecting an island position of an ingot growing furnace, the device comprising: the ingot growing furnace in which an ingot material is melted; a photographing means installed on a top of the ingot growing furnace to acquire an image of a surface of a melt; a control means for detecting a position of an island by analyzing the image acquired by the photographing means; and a seed operating means provided on the top of the ingot growing furnace to descend a seed so that the seed may contact with the surface of the melt, wherein the control means derives a plurality of singular points related to temperature or brightness from the image, derives a plurality of connection lines respectively forming a straight line by connecting a series of singular points to each other, determines a region in which the largest number of intersections are generated as an island among regions in which the plurality of connection lines intersects with each other, and determines whether or not the island is positioned in a seed contact area set to descend the seed.
