摘要(Abstract)：
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 innovative recognition techniques and divides the targeted images into separate patches(patch elements) which conforms to Boolean rule and represents some specific meanings. To define the logic combination of the patch elements, 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 recognition technology.
