中文摘要:
      针对自动泊车过程中车位检测网络复杂,边缘部署困难等问题,提出了一种基于全景图像的车位检测方法。使用Ghost模块对其参数进行量化处理,同时引入EIoU损失函数,对检测尺度进行裁剪,降低计算成本,添加SimSPPF模块来取代YOLOv5s主干中的SPPF,以提高计算效率和准确的目标检测能力。实验结果表明,本文车位检测网络mAP@0.5达到98.2%,参数量、浮点运算量、权重分别降低了86.7%、62.5%、85.4%,检测速度提高了20%,车位检测准确率达到98.1%。
英文摘要:
      A parking space detection method based on panoramic images is proposed to address the challenges of complex networks and difficulties in edge deployment during the automated parking process. The method incorporates the Ghost module for quantization of parameters and introduces the EIoU loss function to crop the detection scale, reducing computational costs. Additionally, the SimSPPF module is integrated to replace the SPPF module in the YOLOv5s backbone, enhancing computational efficiency and accurate object detection capabilities. Experimental results demonstrate that the proposed parking space detection network achieves an mAP@0.5 of 98.2%. The parameter count, floating-point operations, and weights are reduced by 86.7%, 62.5%, and 85.4%, respectively. The detection speed is increased by 20%, and the parking space detection accuracy reaches 98%.
