YOLOv7 Backbone结构图 最好是3D的

很抱歉,我无法提供3D结构图。不过,我可以给你描述一下YOLOv7的Backbone结构。
YOLOv7是目标检测算法YOLO(You Only Look Once)的一个变种。它的Backbone结构主要由卷积神经网络(CNN)组成,用于从输入图像中提取特征。
经典的YOLOv7中,Backbone通常采用Darknet网络结构,它由一系列卷积层和池化层组成。具体来说,YOLOv7的Backbone由若干个Darknet块(Darknet Block)堆叠而成。
每个Darknet块通常包含一组卷积层和一些跳跃连接(skip connection),用于在不同层级上融合不同分辨率的特征。这样做的目的是为了提高模型对不同尺度目标的检测能力。
你可以参考YOLOv7的论文或者相关代码库来获取更详细的结构信息和实现细节。

yolov7 backbone
YOLOv7 is a real-time object detection algorithm that uses a deep neural network to predict the bounding boxes and class probabilities of objects in an image. The backbone of YOLOv7 is a convolutional neural network that is used to extract features from the input image.
The backbone of YOLOv7 is a modified version of the EfficientNet architecture, which is a family of convolutional neural networks designed to balance accuracy and efficiency. The EfficientNet architecture uses a combination of convolutional layers with different kernel sizes and depths, as well as a series of scaling factors that control the number of filters in each layer.
In YOLOv7, the backbone is composed of a series of convolutional layers that extract features from the input image at different scales. These features are then fed into a series of detection heads, which predict the bounding boxes and class probabilities of objects in the image.
Overall, the backbone of YOLOv7 plays a critical role in the performance of the algorithm, as it is responsible for extracting meaningful features from the input image that can be used to accurately detect objects.
