摘要
本文通过对普通数字相片上比例尺的变化规律进行理论研究,找出比例尺的变化规律,根据变化规律设计实验标志并进行相关实验,提出了一种快速获取土地面积的计算方法,并用实验数据对比例尺变化规律进行了验证,通过现场实验计算土地面积并总结了一些提高精度的方法。研究结果表明该方法对于快速估算土地面积具有一定的实用性。
By theoretically analyzing the scale of ordinary digital camera photos,the paper found out the variation of scale,designed the mark of test and did experiments based on the variation disciplinarian.Then it brought forward a method to fast calculate land area.Through the experimental data it validated the changes of scale,then through experiment it calculated the area of land and concluded methods to improve the accuracy.The results showed that the method had certain availability on fast estimation of area.
