Fusion of Coordinate Attention and Deformable Convolutional Networks for
concrete vibration robot recognition
Abstract
To ensure the engineering quality and durability of reinforced concrete,
vibrating is necessary during the pouring process. Currently, the
vibration process during the construction of high-rise buildings is
mainly done manually using handheld vibrating rods. However, manual
vibration relies heavily on human experience and often results in issues
such as over-vibration or insufficient vibration. Once the concrete
solidifies, these problems can lead to irreversible consequences. This
paper proposes a vibration robot that replaces manual vibrating with a
strictly programmed process, improving construction efficiency and
project quality. The vibration robot is based on the YOLOv5s algorithm
and incorporates Deformable Convolutional Networks (DCN) and Coordinate
Attention (CA) mechanisms into the backbone network to enhance target
recognition performance. Through image recognition, the vibration robot
obtains the coordinates of the vibration center point for controlling
the vibration operation. Experimental results show that this method
achieves a target recognition rate of 95.24% and a frame transfer rate
of 16.94 frames per second. Therefore, using a vibration robot for
concrete vibration during pouring holds significant practical value.
