摘要
针对无核白葡萄图像的获取问题,在自制的采集平台上充分考虑了背景纸颜色、光源结构以及打光模式等因素对图像的影响,并采用主客观综合评价图像的方法对比确定各因素的最佳取值水平。结果表明,无核白葡萄机器视觉成像系统的最佳因素取值为:背景纸为白色背景纸,光源结构为条形光源-60°,打光模式为明场模式,此时的图像质量最好。
In order to obtain the image of seedless white grape,the influence of background paper color,light source structure and lighting mode on the image was fully considered on the selfmade acquisition platform.Firstly,the optimal level of each factor is determined by single factor test,then the acquisition platform is optimized by orthogonal test,and finally the optimal value level of each factor is determined by subjective and objective comprehensive evaluation image method.The results showed that the best values of the machine vision imaging system of seedless white grape were:the background paper is white,the light source structure is strip light source-60°,the lighting mode is open field mode.Under the conditions,the image quality is the best.
