指纹拼接方法是建立于对圆柱形客体上指纹进行分段拍摄并在计算机中利用PhotoShop_cs软件进行拼接的方法。其方法是选取几种不同曲率的圆柱形物体,在每一种客体上沿着圆柱面展开的方向捺印一枚指纹,采用近距摄影方法记录其上的指纹。用上述方法对曲率较小客体上的指纹可以一次拍摄下来,对于曲率较大客体上指纹进行分段拍摄并在计算机中拼接,可以得到完整清晰的指纹图像。
Fingerprint stitching method is based on the cylindrical object fingerprinting and shooting in the computer using PhotoShop_cs software splicing method. The method is to select several cylindrical objects with different curvatures, print a fingerprint along the direction of the cylindrical surface on each object, and record the fingerprint on the object by a close-up photography method. With the above method, the fingerprints on the object with small curvature can be shot at a time, and the fingerprints on the object with larger curvature are shot in stages and stitched in the computer to obtain a complete and clear fingerprint image.
