一种用于具有不同深浅颜色产品的视觉检测方法
摘要：
本发明公开了一种用于具有不同深浅颜色产品的视觉检测方法，包括以下步骤：S1：待检测的产品进入拍摄区域；S2：曝光拍照：针对特征1，调节光源的亮度为L1并拍摄第1张照片；针对特征2，调节光源的亮度为L2拍摄第2张照片......针对特征N，调节光源的亮度为LN并拍摄第N张照片，其中，N≥2，特征1、特征2......特征N的颜色深浅不同，L1、L2......LN各不相同；S3：特征识别：利用第1张照片与预设照片对比识别特征1，利用第2张照片与预设照片对比识别特征2......利用第N张照片与预设照片对比识别特征N。本发明具有步骤简单、操作方便、特征明暗相差大时仍可准确识别等优点。
摘要（英）：

The invention discloses a visual detection method for products with different shades of colors. The visual detection method comprises the following steps: S1, enabling a product to be detected to enter a shooting area; S2, exposure shooting: adjusting the brightness of a light source to be L1 and shooting the first picture according to the characteristic 1, adjusting the brightness of the light source to be L2 and shooting the second picture according to the characteristic 2 . . . , and adjusting the brightness of the light source to be LN and shooting the Nth picture according to the characteristic N, wherein N is greater than or equal to 2, the color depths of the characteristic 1, the characteristic 2, . . . and the characteristic N are different, and L1, L2, . . . LN are different; andS3, characteristic identification: contrasting the first picture with a preset picture to identify the characteristic 1, contrasting the second picture with the preset picture to identify the characteristic 2, . . . and contrasting the Nth picture with the preset picture to identify the characteristic N. The visual detection method disclosed by the invention has the advantages of being simple insteps, convenient to operate, capable of accurately identifying the characteristics when the characteristic shade difference is large, and the like.
