which is an extension of the YOLOv5s network
model. In order to strengthen the YOLOv5s
network's backbone and neck networks, a mix of the
global attention mechanism and the convolutional
block attention module was utilized. Deep learning
neural networks are able to extract more features
thanks to these attention techniques, which enhance
the representation of global interactions and minimize
the loss of information characteristics. Improving
target feature extraction and reducing computation
required for model operation are both achieved by the
inclusion of the CBAM into the CSP module. The
suggested model employs the most current SIoU
(SCYLLA-IoU LOSS) as the boundary box loss
function to enhance the prediction box regression. A
lightweight network model that meets the demands of
real-time monitoring is constructed on top of the
upgraded YOLOv5s model. Knowledge distillation
technology reduces the model's computational effort
while enhancing detection speed. All three
metrics—precision, recall, and mean average
precision—show that the suggested model beats the
prior YOLOv5s network model in experimental
results. Even in dim light and from varying distances,
the suggested model might be able to better detect
helmet wear.
The workplace must be visually inspected and
immediately inform the workers when they do not
wear a safety helmet so that injuries on the job could
be avoided (Yange Li, et al., 2020). For that matter, a
need arises for automatic real-time detection from the
great amounts of unstructured visual data created by
on-site video monitoring systems. Despite the
abundance of research on deep learning-based helmet
detection models for traffic surveillance, there has
been surprisingly little discussion of a suitable
solution for industrial use, especially when
considering the complexity of the environment on a
construction site. To that end, we create a system that
uses deep learning to identify safety helmets on the
job site in real time. This approach makes use of the
convolutional neural network-based SSD-MobileNet
algorithm. A public dataset with 3,261 photos of
safety helmets was created and made available to the
public. The photographs came from two sources: the
workplace's video surveillance system and open
images retrieved with web crawler technology. The
picture set is sampled in a manner that is about 8:1:1,
with each set serving as a training set, validation set,
and test set. Using the SSD-MobileNet method, the
experimental findings show that the given deep
learning-based model can efficiently and accurately
detect risky operations including the failure to wear a
helmet on a construction site.
A comprehensive system of safety management
has been built up by power grid enterprises within
China to regulate restrictions, such as all safety rules
and two tickets embodied into one, for the assurance
of the operation's stability and protection of staff
(Songbo Chen, et al., 2020). On the other hand, a
good number of workers still show lack of safety
consciousness by not wearing helmets in their jobs
inside substations. Electric power workers must
always wear safety helmets to protect their heads
from potentially lethal accidents including electric
shock and strikes. Not only does working without a
helmet contradict the safety control system; it depicts
one as careless with the lives and possessions of
people. However, these controlling measures
currently are not efficient, effective, and quick
enough to detect and prevent such acts. This research
suggests using the Improved Faster R-CNN algorithm
to check if a person is wearing a safety helmet so that
we may better prevent this dangerous behavior.
Taking into account the actual circumstances, the
Retinex image improvement is implemented to
increase the quality of images captured in substations
of outside complex situations. Additionally, the K-
means++ technique is utilized to enhance the helmet's
adaptability to its little size. The findings of the
experiments demonstrate that the Improved Faster R-
CNN algorithm achieves better mean-average
precision than the Faster R-CNN method, allowing
for the automated identification of safety helmet
wears in real-time.
The construction industry is still sky-high in its
expansion, hence new and unique dangers to workers'
health and safety arise out of active construction.
Wearing helmets while on a construction site can
greatly lower the chance of incurring an injury
(Lihong Wei, et al., 2024). Hence, the objective of
this research is to propose a deep learning approach
in real-time for detecting whether construction
workers are using helmets or not. This study
examines the training outcomes of the YOLOv5s
network that was chosen through trials. Given that it
has a weak ability to identify tiny items and objects
that are partially obscured. This leads to a number of
improvements to the YOLOv5s network, a change to
the feature pyramid network to a BiFPN bidirectional
feature pyramid network, and an upgrade to Soft-
NMS from NMS, the post-processing methodology.
The loss function is optimized hereby enhancing the
convergence and detection speed of the model, which
introduces BiFEL-yolov5s: A YOLO V5 series
model enhanced by a combination of BiFPN
networks and Focal-EIoU Loss. The model's average
accuracy is improved by 0.9%, its recall rate is
