System and method for imaging evidence deposited on curved surfaces

摘要

Systems and methods are disclosed for capturing images of latent evidence such as a latent fingerprint provided on a curved or irregular surface of an object. According to certain embodiments, a latent fingerprint provided on a curved or irregular surface of an object is illuminated by a UV lamp. An aspect of the latent fingerprint is specularly reflected from the surface of the object and captured by an image capturing device. In various embodiments, the UV lamp is repositioned, or the object is rotated and translated, such that a second aspect of the latent fingerprint is then specularly reflected from the surface of the object and captured by the image capturing device. The first and second images are then integrated by performing a pixel-to-pixel comparison of corresponding pixel data in the captured images. A device is also provided for rotating and translating the object for use in the disclosed embodiments.
