A mask identification and social distance monitoring system using Unmanned Aerial Vehicles (UAV) in the outdoors has been proposed for a health establishment. The above approach performed surveillance of the surrounding area using cameras installed in UAVs and internet of things technologies, and the captured images seem useful for tracking the entire environment. However, innate images from unmanned aerial vehicles show an adaptable visual effect in an uncontrolled environment, making face-mask detection and recognition harder. The UAV picture first had to be converted to grayscale, then its contrast was amplified. Image contrast was improved using Optimum Wavelet-Based Masking and the Enhanced Cuckoo Methodology (ECM). According to the contrast-enhanced image, Gabor-Transform (GT) and Stroke Width Transform (SWT) methods are used to derive attributes that help categorise mask-wearers and non-mask-wearers. Using the retrieved attributes, a Weighted Naive Bayes Classification (WNBC) detected masks in the images. Additionally, a deep neural network-based, the faster Region-Based Convolutional Neural Networks (R-CNN) algorithm combined with Adaptive Galactic Swarm Optimization (AGSO) is being used to identify appropriate and incorrect face mask wear in images, as well as to monitor social distancing among individuals in crowded areas. When the system recognises unmasked individuals, it sends their information to the doctor and the nearby police station. One unmanned aerial vehicle's automated system alert people via speakers, ensuring social spacing. The problem involves a large percentage of appropriate and incorrect face mask wear using data from GitHub and Kaggle, including a training repository of 16,000 images and a testing data set of 12,751 images. To enhance the performance of the model's learning, the methodology of 10-fold cross-validation will be used. Precision, recall, F1-score, and speed are then measured to determine the efficacy of the suggested approach.
已为医疗机构提出了一种使用无人机 (UAV) 进行口罩识别和社交距离监测的系统。上述方法使用安装在无人机上的摄像头和物联网技术对周围环境进行监控,捕获的图像似乎可用于跟踪整个环境。然而,由于无人飞行器固有的图像在不受控制的环境中呈现出适应性的视觉效果,使得口罩检测和识别变得更加困难。首先必须将无人机图像转换为灰度图像,然后放大其对比度。使用最优小波掩蔽和增强型布谷鸟算法 (ECM) 提高图像对比度。根据对比度增强后的图像,使用 Gabor 变换 (GT) 和笔画宽度变换 (SWT) 方法得出有助于对戴口罩者和未戴口罩者进行分类的属性。使用检索到的属性,加权朴素贝叶斯分类器 (WNBC) 在图像中检测口罩。此外,还将使用基于深度神经网络的更快区域卷积神经网络 (R-CNN) 算法结合自适应银河群优化 (AGSO) 来识别图像中合适和不正确的口罩佩戴情况,以及监测拥挤区域中个体之间的社交距离。当系统识别出未戴口罩的人时,它会将他们的信息发送给医生和附近的警察局。一架无人驾驶飞机的自动系统通过扬声器向人们发出警报,以确保社交距离。该问题涉及使用来自 GitHub 和 Kaggle 的大量合适和不正确的口罩佩戴数据,包括一个 16000 张图像的训练存储库和一个 12751 张图像的测试数据集。为了增强模型学习的性能,将使用 10 倍交叉验证方法。然后测量精度、召回率、F1 分数和速度,以确定所建议方法的效果。
