摘要： This paper presents a comparative research of nine different combinations of imaging environmental factors using orthogonal test approach to gain optimal illumination in an image acquisition device which was self-designed. The effect of four different environmental factors such as shoot distance, lamp number, lamp height, lamp side distance have been investigated on the key parameters. Experimental results based on L(9)(3)(4) orthogonal test design shows that under different combination of environmental factors, there are obvious differences between illumination intensity and illumination uniformity of images and which are mainly affected by the shoot distance and lamp number. Based on these experiments, we get two preferable combinations. Attention is concentrated on finding the best. Through further analysis and discussion, the best combination is identified. Our experimental results indicate that orthogonal test here is very suitable for gaining optimal environmental factors.
