METHOD FOR GETTING 3-DIMENSIONAL SHAPE INFORMATION OF A PANEL

摘要

PURPOSE: A method for collecting 3-dimensional shape information of panels is provided to correct distorted two-dimensional coordinate into ideal two-dimensional coordinate. CONSTITUTION: A method for collecting 3-dimensional shape information of panels comprises following steps. Line-shaped laser is emitted to a panel(S10). The emitted laser is sensed by a visual sensor(S20). Two-dimensional coordinate is calculated using distorted coordinates sensed by a visual sensor(S30). The two-dimensional coordinate is changed into three-dimensional coordinate which expresses the surface shape of a panel(S40).
