| 摘 要： | 应用称重法和光电法对图纸面积的量测精度研究。结果表明:两种方法都可达到规范要求,且简单易行,尤其是称重法可降低成本。称重法主要误差来源是剪裁走线不准;光电法主要误差来源是图纸染色不均匀。

| Abstract: | Describes a comparison and precision analysis of area measurement on blueprint with weigh and photo-electric methods. The results showed that both met the standard requirements and are easy to use. The weigh method can save the cost especially. Its major error cames from inaccuracy in edgo line cutting. The major error of photo-electric method lies on unevenly dyeing of blueprint. |
