Design and Implementation of Digital Extraction Software for Temperature Self-Recording Paper Trace

摘要: 温度自记纸是客观记录温度的十分宝贵的历史气象资料，记载了分钟级的温度变化特征。为了满足气象防灾减灾以及气象信息化业务的需要，基于图像处理技术，采用图像矫正、器差订正多种检查矫正方法，研发了温度自记纸迹线数字化提取软件，实现了对温度自记纸图像的识别提取和质量控制，为最终形成长时间序列、高分辨率的温度自记纸数据提供了技术支持。

Abstract: Temperature self-recording paper is a very valuable historical meteorological data that objectively records temperature, and records the minute-level temperature change characteristics. In order to meet the needs of meteorological disaster prevention and mitigation and the meteorological information business, based on image processing technology, multiple inspection and correction methods such as image correction and device error correction are used, and a digital extraction software for temperature self-recording paper trace is developed. This software realizes the identification, extraction and quality control of temperature self-recording paper images and provides technical support for the final formation of long-time series, high-resolution temperature self-recording paper data.
