In the industrial production, it is frequently needed to test the area of the irregular shape plane object. In this paper
optical method is used to perform non-contact area measurement of random shape plane object testing and matrix
CCD-computer system is combined to realize real time automatic measurement. In this paper principle and method for
area measurement of arbitrary shape plane object using matrix CCD-microlens-compute system is present. Testing
device is designed from the hardware and the software. At last the factors affecting on the accuracy are analyzed. By
experiment, it is proved that this method processes fast speed, high accuracy and strong adaptability. The system makes
on-line testing possible and may be applied in the modern industrial testing conveniently.
