Position detection of article
专利汇可以提供Position detection of article专利检索，专利查询，专利分析的服务。并且PURPOSE: To achieve a highly accurate detection of position, by determining two virtual straight lines by using least square method based on a data indicating edge positions on two sides of a corner part to compare the position of intersection therebetween with a normal working position data.
CONSTITUTION: An image taken with a TV camera 87 of an area 120 defined by two sides (a) and (b) of a corner part of a window glass A is taken into a processor in a control means 110, edge position a
1 , a
2 ... and b
1 , b
2 ... data of the sides (a) and (b) are measured and stored to determine an intersection P
1 between virtual straight lines 121 and 122 approximate to the sides (a) and (b) using least square method and likewise, intersections P
2 WP
4 are determined about other corners to calculate position coordinates. Then, the results are compared with the coordinates indicating a normal working position with respect to a working robot 88 corresponding to intersections P
1 WP
4 to determine data errors between both the coordinates. Prior to a coating work, the data error is fed back to the robot 88 to correct coordinates at a teaching point thereby achieving a primer coating work for the glass A at a high accuracy.
