中文摘要: 为了提高植物叶面积的测定精度,基于计算机和常规扫描仪,采用计算机图像处理技术,开发了温度、湿度自记纸数据自动读取系统(AutoGPR1.0)。系统能根据自记纸背景色与温度、湿度记录迹线颜色差异,将记录迹线提取出来,使计算机读出自记纸记上实测的温度、湿度值,获取连续数据。系统计算的相对湿度绝对误差≤2%,温度的绝对误差≤0.2℃。
中文关键词: 温度，湿度，自记纸数据，自动读取
Abstract:Based on the computer and the general scanner, adopting the technology of picture disposure of computer, the Auto GPR1.0 system is developed to increase the measuring precision of the area of leaves. This system can pick up the noting curves according to the differences between the colore of auto-writing paper background and that of noting curves of temperature or humidity, then the computer can obtain continuous data from the values of temperature and humidity noted in auto-writing paper. In system calculation, the absolute error of temperature is less than 0.2℃, and that of humidity is less than 0.2%.
