摘要：
A method for the optimization of illumination in line-scan camera systems is proposed. By using this method it is possible to calculate the optimal positions and luminous intensities of the light sources to obtain the desired illuminance at a surface. The proposed method is especially suitable fur producing uniform illumination on a line. The method can be used with several types of light source, because experimental general models can be used for the lamps. The method is based on the regularized least squares optimization. The performance of the method is evaluated by comparing the calculated and measured illuminances before: and after the optimization.
