基于激光图像分析的苹果表面损伤和内部腐烂检测（Apple Surface Damage and Inner Decay Detection Based on Laser Scattering Image Analysis）
苹果 损伤 内部腐烂 计算机视觉
2009/8/11
利用波长650nm、功率25mW的半导体激光及计算机视觉技术，初步探讨了利用激光图像分析检测苹果（嘎拉）采后表面损伤和内部腐烂检测的可行性。利用钢球砸伤，模拟苹果在采收和运输过程中受到的损伤；利用微量注射器从苹果底部将15μL(105/mL孢子浓度)的青霉菌液注入果心部位使其腐坏，模拟苹果内部的腐烂。进行激光图像检测试验，结果表明，受损伤后苹果图像像素数S3在36h达到最高值（3964），且在1～...
