摘　　要：高质量成像是快速读取图像中条码信息的重要保障。影响成像质量的参数有信号增益和曝光时间,两者取值范围广,组合后的相似参数对多。为快速找到可稳定解码的参数对,将参数调整过程分为条码搜索、参数优化和参数确认三个阶段,各阶段的侧重点不同,共同完成参数调整过程。测试证明,所述方法具有速度快、参数稳、解码可靠的特点。High quality imaging is an important guarantee for fast reading of barcode information in images.The parameters that affect the imaging quality include signal gain and exposure time,which have a wide range of values,and there are many similar parameters pairs after combination.In order to quickly find the parameter pairs that can be decoded stably,the parameter adjustment process is divided into three stages:barcode search,parameter optimization and parameter confirmation.The focus of each stage is different to jointly complete the parameter adjustment process.The test shows that the method has the characteristics of fast speed,stable parameters and reliable decoding.
