摘要

由于路灯灯光不足,行人和司机夜间能见度不佳,导致这段时间内发生事故。计算机的视觉系统与人类不同,所有温度高于零的物体都可以通过热摄像机发出红外辐射。在本研究中,作者通过YOLOv4算法识别RGB图像的热图像,并将YOLOv4 Scaled YOLOv4进行检测。系统的性能是根据精度、召回、f1-score和mAP来衡量的。实验是在人体的热成像数据库里进行的。使用的场景是探测距离为5m、10m、15m和20米的物体。检测结果发现算法Scaled YOLOv4 CSP的值为94.3%,recall 83.8%, f1-Score 88.7%和mAP 86.9%。这些结果受到培训意象、验证意象和测试意象的数据测量和数据数量的影响。关键字:热成像,YOLO, YOLOv4, Scaled-YOLOv4,检测行人在夜间照明到街上灯光导致有时甚至死亡的可见性。该计算机的视觉系统与人类不同,任何低于零温度的物体在使用热相机时都可能受到红外线辐射。在这项研究中,当局使用YOLOv4的热成像技术,用物体探测算法将YOLOv4进行识别。系统表现基于珍贵、回忆、f1分数和地图。实验结果显示了一种与人类对象无关的热图像。过去的场景是在5米、10米、15米和20米的距离内发现物体。根据估计的浓度为YOLOv4 CSP算法,根据测试值为94.3%的浓度,88.8%的召回,88.7%的f1-Score, 88.9%的地图显示。这些结果受到来自培训、验证、验证图像的数据和数据数据的影响。热成像,YOLO, YOLOv4, scad -YOLOv4,对象检测

Perbandingan Algoritma YOLOv4 dan Scaled YOLOv4 untuk Deteksi Objek pada Citra Termal
