摘　　要：纸质历史影像地图因纸质老化、图像褪色、易损坏、不易保存的缺点,亟待电子化、数字化保护。针对不适合电子扫描的纸质历史影像地图,提出了一种基于非量测相机摄影方式的历史地图栅格化方法,采用近景摄影测量手段,充分利用地图均匀分布的公里网格进行地图内定向,再利用近期数字正射影像选取同名控制点对历史影像进行几何纠正,生成CGCS2000坐标系数字正射影像地图。该方法在无锡县纸质历史影像地图纠正项目中得到良好应用,证明方法简便可行,数据规格和精度能够满足相关规范要求,对同类型历史影像底图的保护和利用具有较好的技术借鉴意义。Due to the drawbacks of aging,fading,easy damage,and difficulty in preservation,paper historical image maps urgently require electronic and digital protection.Aiming at the paper historical image maps that are not suitable for electronic scanning,a rasterization method of historical maps based on non-measurement camera photography is proposed.Close range photogrammetry is used to make full use of the evenly distributed kilometer grid of the map for in-map orientation,and then use the recent digital orthophoto image to select the same name control point to perform geometric correction on the historical image to generate the CGCS2000 coordinate system digital orthophoto map.The method has been well applied in the paper historical image map correction project in Wuxi county,which proves that the method is simple and feasible.The data specifications and accuracy can meet relevant regulatory requirements,and it has good technical reference value for the protection and utilization of paper maps of the same type of historical image.
