Footwear impressions are one of the most common forms of evidence to be found at a crime scene, and can potentially offer the investigator a wealth of intelligence. Our aim is to highlight a new and improved technique for the recovery of footwear impressions, using three-dimensional structured light scanning. Results from this preliminary study demonstrate that this new approach is non-destructive, safe to use and is fast, reliable and accurate. Further, since this is a digital method, there is also the option of digital comparison between items of footwear and footwear impressions, and an increased ability to share recovered footwear impressions between forensic staff thus speeding up the investigation.
鞋印是犯罪现场最常见的证据形式之一，有可能为调查人员提供大量情报。我们的目的是强调一种使用三维结构光扫描来提取鞋印的新的改进技术。这项初步研究的结果表明，这种新方法是非破坏性的，使用安全，且快速、可靠、准确。此外，由于这是一种数字方法，还可以对鞋类物品和鞋印进行数字比对，并且法医人员之间共享提取的鞋印的能力增强，从而加快调查速度。
