摘　　要：针对狭缝摄影胶片参数测量和处理的自动化低,人为因素多,提出一种新型胶片影像判读仪。通过将光源照射到待扫描的材料上完成图像的获取,光源照射到CCD上实现光电转换。对胶片图像进行数字化处理,利用软件进行图像处理。结果表明,应用该判读仪实现了大幅面(830mm×190mm)彩色胶片图像输入。平面结构和精密的传动系统保证了测量要求的全幅面小于±0.1mm的精度,提高了胶片判读的自动化程度和数据的精确测量及处理。Aiming at the low level automation and lots of human factors in the measurement and processing of slit film parameter, we introduced a novel film image reader. The light source irradiated the material to be scanned to complete the image acquisition and irradiated the CCD to achieve photoelectric conversion. The slit photographic film images were digitized and processed using software. The results show that the reader realizes large format （830 mm× 190 mm）color film image input. The platform structure and the precision of the transmission system ensure the all format precision of less than ± 0.1 mm, which is the measurement requirement, it can improve the automation of the film image reader, as well as the accurate measuring and processing of data.
