High-speed three-dimensional (3D) surface imaging by structured-light profilometry is currently driven by industrial needs, medical applications, and entertainment. According to Market Research Future Analysis, the global 3D camera market has been valued at ~US$13.4 Billion by the end of 2026 with 14.2% of a compound annual growth rate during the forecast period from 2020 to 2026. However, the limited speeds in fringe pattern projection, image acquisition, and data transmission have strained the existing methods from reaching kilohertz (kHz)-level acquisition, processing, and display of 3D information during the occurrence of dynamic events (i.e., in real time).To overcome these limitations, we recently invented CoaXPress-interfaced band-limited illumination profilometry (CI-BLIP), which enables real-time 3D surface information reconstruction at 1 kHz. Compared with the existing technologies, CI-BLIP has advantages in the convenient system operation, the high-speed real-time response, and the easier system miniaturization. Our initial tests have shown the promising potential of CI-BLIP to diverse applications, including industrial inspection, aerodynamics, and machine vision.This NSERC I2I Phase I project aims to further developing the CI-BLIP technique toward a commercial product. In total, three Aims are proposed to integrate the proof-of-concept CI-BLIP system into a compact prototype, to improve image reconstruction speed in CI-BLIP, and to demonstrate real-time high-speed 3D surface imaging using the CI-BLIP prototype. The well-established technical foundation, solid preliminary results, and highly experienced team will ensure the on-time execution and fast progress of this project. In this regard, this project will pave the way for future technology transfer and device commercialization.

结构光轮廓术的高速三维(3D)表面成像目前受到工业需求、医疗应用和娱乐的推动。根据市场研究未来分析，截至2026年底，全球3D相机市场价值约为134亿美元，在2020至2026年的预测期内，复合年增长率为14.2%。然而，条纹投影、图像采集和数据传输的速度有限，使得现有的方法无法在动态事件发生时(即实时)获取、处理和显示三维信息。为了克服这些限制，我们最近发明了CoaXPress接口的带限照明轮廓术(CI-BLIP)，它能够在1 kHz下实时重建三维表面信息。与现有技术相比，CI-BLIP具有系统操作方便、实时响应速度快、系统易于小型化等优点。我们的初步测试表明，CI-blip在工业检测、空气动力学和机器视觉等领域具有广阔的应用前景。NSERC I2I第一阶段项目旨在将CI-blip技术进一步发展为商业产品。总而言之，提出了三个目标：将概念验证CI-blip系统集成到紧凑的原型中，提高CI-blip中的图像重建速度，以及使用CI-blip原型演示实时高速三维表面成像。雄厚的技术基础、扎实的前期成果、经验丰富的团队将确保本项目按时实施、快速推进。在这方面，该项目将为未来的技术转让和设备商业化铺平道路。
