TL;DR: A new measurement method for human comfort assessment levels for stadiums is proposed and demonstrated based on a specific computer vision and image processer system.

TL;DR: In this paper , a hybrid method for damage detection and condition assessment of hinge joints in hollow slab bridges using physical models and vision-based measurements was proposed, where the stiffness reduction of the hinge joints is taken as the damage degree and condition level of inspected hinge joints.

TL;DR: In this article, the authors show that flexible structures such as footbridges, stadiums, and large slabs are prone to narrowband excitations generated by occupants, and both the excitation and response are of a nonstationary nature.

TL;DR: In this paper, a quasi-distributed optical measurement method is proposed, which includes erecting a measuring device and preparing initial adjustment; marking image pixels and actual distances; manufacturing quasi distributed measuring point image templates and performing matching optimization; and measuring and storing quasi distributed structure displacement automatically.

TL;DR: Comparative analyses of the results obtained from the experiments with various types of vapor levels and vision targets indicate that the environmental factor has a significant effect on the system performance and measurement accuracy of the vision-based displacement measurement system.
