摘　　要：针对大多数数字多用表不具备通信接口的问题,开发了一种基于图像识别技术的自动化检定系统。系统采用创新型的识别技术,将待识别图像根据需要分割为一个个独立识别块(块元),块元出现的规律为布尔型,每个块元代表某种特定的含义。在模板中定义这些块元之间的逻辑组合关系,只要识别出块元后即可通过它们的逻辑关系得到对应的数字量。通过这种图像识别技术,识别准确率可达99.9%以上。Most of digital multimeters are not equipped with communication interfaces. Therefore an automatic calibration system for digital multimeter based on image recognition is developed. The system adopts innova-tive recognition techniques and divides the targeted images into separate patches （patch elements） which con-forms to Boolean rule and represents some specific meanings. To define the logic combination of the patch el-ements, the corresponding digital quantity can be concluded through logic relationship with the patch element recognized. The system achieves a recognition rate up to 99.9% due to the implementation of the image recog-nition technology.
