| 摘 要： | 针对当前大幅面图纸分块扫描拼接中存在的问题,提出一种基于改正扫描仪误差的大幅图纸整体平差的拼接方法.该方法通过平移黑白相间的格网板建立扫描仪的误差模型,同时利用少量的控制点及连接点,然后通过整体平差来直接解求各扫描图像块的几何变换参数.实践证明这种方法具有拼接精度高、速度快以及可不限图幅大小等优点.

| Abstract: | A whole adjustment mosaic method based on collation of scanner's error is put forward. This method builds a new collation model of scanner's error through offsetting black and white grid, and acquires geometry transform parameter through whole adjustment using a few control points and joint points. Experiment shows that this method has unique advantages: a high accuracy and free size of maps. |
