Special Issue Information

Dear Colleagues,

The field of 3D optical measurement has witnessed significant advancements in recent years. These advancements have been driven by the increasing demand for high-precision, non-contact measurement techniques that can capture complex 3D shapes with accuracy and efficiency. One promising research direction is the development of advanced imaging technologies, such as structured light techniques, multi-camera systems, and laser scanning techniques. These technologies have greatly enhanced the measurement resolution and accuracy, and researchers are now exploring the use of advanced algorithms to further improve the imaging quality and processing speed. Additionally, there is a growing interest in integrating 3D optical measurement with other sensing modalities, such as thermal imaging, ultrasound, laser Doppler, and laser ranging, to obtain a more comprehensive understanding of the objects being measured. This integration opens up new possibilities for applications in medical diagnostics, material characterization, and quality control. Overall, the future of 3D optical measurement holds great promise, with continued research in advanced imaging technologies, integration with other sensing modalities, and the development of portable devices expected to further enhance the capabilities and applications of 3D optical measurement systems.

This Special Issue aims to showcase the latest research and developments in the field of 3D optical measurement and provide a platform for researchers to share their findings and insights. Theoretical, numerical, and experimental papers are welcomed. Topics include, but are not limited to, the following:

  • Advanced imaging technologies for 3D optical measurement;

Monocular stereo vision has excellent application prospects in the field of microrobots. On the basis of the geometric model of bifocal imaging, this paper proposes a monocular depth perception method by liquid zoom imaging. Firstly, the configuration of a monocular liquid vision system for depth measurement is presented, and the working mechanism of the system is analyzed through theoretical derivation. Then, to eliminate the influence of optical axis drift induced by the liquid gravity factor on the measurement results, the target image area is used as the calculation feature instead of the image vector length. A target area calculation method based on chain code classification and strip segmentation is proposed. Furthermore, in response to the fluctuation problem of liquid lens focal power caused by factors such as temperature and object distance, a dynamic focal length model of the liquid zoom imaging system is constructed after precise calibration of the focal power function. Finally, a testing experiment is designed to validate the proposed method. The experimental results show that the average error of depth perception methods is 4.30%, and its measurement time is only on the millisecond scale. Meanwhile, the proposed method has good generalization performance. Full article
