BGA 소자의 볼 정점 높이 측정을 위한 스테레오 비젼 알고리즘 개발
The Development of a Stereo vision algorithm for Height Measurement of Ball Peak Point of BGA Device

초록
In this paper, We proposed the stereo image modeling using 2-dimensional images captured by the high resolution cameras to inspect the ball defects of BGA(Ball Grid Array) device. The proposed algorithm consists of the package/ball area extraction part, the FOV(Field of View) calibration part, the top point matching part, and ball height measurement part, In the package/ ball area extraction part, the package and ball areas are separately extracted in a left and right image by the extraction algerian. Through the experiment, we draw out the result.
