【摘要】 针对空港旅检口岸监管工作中先期机检查验模式持续发展的要求，研究行李数字立体成像技术，生成刻画行李表观信息的三维网格化模型，结合新型机检设备获取的反映行李内部结构的三维体素化数据，完成行李内外部信息的整体建模。提出了基于直线运动的行李数字立体成像的技术路线，包括相机标定、位置估计、三维模型重建、内外信息融合渲染等关键步骤，获得了新颖、良好的重建和渲染效果，为进一步辅助现场作业和识别嫌疑行李奠定了基础。更多还原

【Abstract】 In view of the continuous development of the beforehand inspection mode in Customs passenger-inspection of airports, this paper studied the baggage digital stereo imaging technology to generate a 3D model depicting the baggage appearance information. Combined with the 3D voxel data reflecting the internal structure of the baggage acquired by the new equipment,the overall modeling of the internal and external information of the baggage was completed. The pipeline of baggage digital stereo imaging based on linear motion was proposed, and the key steps such as camera calibration, position estimation, 3D model reconstruction, internal and external information fusion and rendering were realized. Novel and good reconstruction and rendering effects are obtained, which lay a foundation for further assisting on-site operation and identifying suspected baggage.更多还原
