Towards Commercialization of High-Speed CoaXpress-Interfaced Band-Limited Illumination Profilometry (CI-BLIP) (Phase 1)

高速三维（3D）表面成像的结构光轮廓术目前是由工业需求，医疗应用和娱乐驱动的。根据市场研究未来分析，到2026年底，全球3D相机市场的价值约为134亿美元，在2020年至2026年的预测期内，复合年增长率为14.2%。然而，条纹图案投影、图像采集和数据传输的有限速度使现有方法在动态事件（即实时）发生时无法达到千赫兹（kHz）级的3D信息采集、处理和显示。为了克服这些限制，我们最近发明了coaxpress接口带限制照明轮廓术（CI-BLIP），它可以在1khz下实时重建3D表面信息。与现有技术相比，CI-BLIP具有系统操作方便、高速实时响应、易于系统小型化等优点。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多种应用中具有广阔的潜力。NSERC I2I第一期项目旨在进一步将CI-BLIP技术推向商业产品。本文提出了将概念验证CI-BLIP系统集成到紧凑原型中的三个目标，以提高CI-BLIP中的图像重建速度，并使用CI-BLIP原型演示实时高速三维表面成像。完善的技术基础、扎实的前期成果和经验丰富的团队将确保本项目的按时执行和快速进展。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。

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.
