Research on track fastener positioning method based on local unidirectional template matching

open access: yesScience Progress, 2021
Commonly used fastener positioning methods include pixel statistics (PS) method and template matching (TM) method. For the PS method, it is difficult to judge the image segmentation threshold due to the complex background of the track. For the TM method,

Design Approach for Lateral Capacity of Dowel-Type Steel Connections in Precast Reinforced Concrete Elements

open access: yesFrontiers in Built Environment, 2021
In precast concrete buildings, connections play a key role. Among them and especially in industrial buildings, the ability to transfer a shear force from the beam to the column is often left to steel bars (often a single one) that act as dowels.

Rail Fastener Positioning Based on Double Template Matching

open access: yesComplexity, 2020
For global template matching (GTM), which is commonly used in the positioning of rail fasteners, only the fastener template is used to search the global image in both two dimensions, which will result in errors in two dimensions, and the lower ...
