| heal.abstract |
A strobe light was used as a light source for the acquisition of images for the detection of cracks in eggs using machine vision. This light source would potentially enable a camera to obtain a good quality image in a shorter time frame than required by constant incandescent lighting. A circuit was developed to synchronize the firing of the strobe light with the acquisition of the image by the camera. Success rates for egg inspections using the two lighting methods (strobe and incandescent) were compared for a mixture of egg sizes and for medium, large, and extra large eggs. The response surfaces were visibly different depending on type of back illumination of eggs used. However, very little difference was found between the maximum success rates for each lighting method. Maximum success rates were approximately 90% for each illumination method (95% for medium eggs.) Range of values for optimization of the two software constants was also very similar for both types of lighting. Optimum success rates were obtained by defining crack length as 150 to 190 pixels and filter factor as 35 to 40. |
