The forensic science community raised the need for improved evidence recognition, collection, and visualization analytical instrumentation for field and laboratory use. While the 3D optical techniques for imaging static objects have been extensively studied, there is still a major gap between current knowledge and collecting high‐quality footwear and tire impression evidence. Among optical means for 3D imaging, digital fringe projection (DFP) techniques reconstruct 3D shape from phase information, achieving camera‐pixel spatial resolution. This paper presents a high‐resolution 3D imaging technology using DFP techniques dedicated to footwear and tire impression capture. We developed fully automated software algorithms and a graphical user interface (GUI) that allow anyone without training to operate for high‐quality 3D data capture. We performed accuracy evaluations and comparisons comparing with the commercial high‐end 3D scanner and carried out qualitative tests for various impressions comparing with the current practices. Overall, our technology achieves similar levels of accuracy and resolution with a high‐end commercially available 3D scanner, while having the merits of being (1) more affordable; (2) much easier to operate; and (3) more robust. Compared with the current practice of casting, our technology demonstrates its superiority because it (1) is non‐destructive; (2) collects more evidence detail than casts, especially when an impression is fragile; (3) requires less time and money to collect each piece of evidence; and (4) results in a digital file that can easily be shared with other examiners. 相似文献

On February 28, 2008, the State Council Information Office published a white paper entitled China's Efforts and Achievements in Promoting the Rule of Law. This document is the first white paper published by the government on China's rule of law. It contains eight chapters and six appendices to review China's achievements on the road to practicing the rule of law in a compre- hensive way, and to expound the official Chinese policy and position on this is- sue. With some essential points inside, the publication of this white paper is of great significance, especially this year, to China's rule of law, human rights prog- ress, and its communication and dialogue with the international community. 相似文献

Although a devout Evangelical, living in an era that largely predated the dissemination of sexological discourses of female same-sex desire, Constance Maynard (1849–1935), the prominent Victorian educational reformer, pursued a series of same-sex relationships. This essay focuses on Maynard's relationship with the Anglo-Irish Marion Wakefield (1876–1956), exploring the role of Maynard's erotic imagination in the constitution, contestation, and consolidation of the imagined geographies of imperialist discourse. Maynard's erotic positioning of her lover in diverse imperial landscapes reveals the ostensibly ‘private’ discourses of the erotic imagination to be profoundly implicated in the ‘public’ discourses of empire. At the same time, the domestic settings in which these landscapes were imagined and in which the women's illicit desires were enacted, pose a challenge to the gendered spatial dichotomies—private/public, domestic/imperial, and home/away—of both imperialist discourse and the historiography of empire. 相似文献

International and national level disability inclusive discourse, policy and strategy typically render invisible the institutional structures, political economies and socio-cultural power relations that constitute the lived experience of disability. The lack of robust information on disability extends these theoretical blind spots to the absence of disability in official statistics, political dialogue and social policy. Empirically grounded, inclusive research that recognises disability as embedded in globalised political economies and culturally specific power relations is required to address the theoretical, statistical and programmatic invisibility of disability. Such research will provide a solid knowledge base on which to build effective inclusive interventions. 相似文献
