一、YOLOv11原始模型结构介绍
YOLOv11
原始模型结构如下：
# Ultralytics YOLO 🚀, AGPL-3.0 license
# YOLO11 object detection model with P3-P5 outputs. For Usage examples see https://docs.ultralytics.com/tasks/detect
# Parameters
nc: 80 # number of classes
scales: # model compound scaling constants, i.e. 'model=yolo11n.yaml' will call yolo11.yaml with scale 'n'
# [depth, width, max_channels]
n: [0.50, 0.25, 1024] # summary: 319 layers, 2624080 parameters, 2624064 gradients, 6.6 GFLOPs
s: [0.50, 0.50, 1024] # summary: 319 layers, 9458752 parameters, 9458736 gradients, 21.7 GFLOPs
m: [0.50, 1.00, 512] # summary: 409 layers, 20114688 parameters, 20114672 gradients, 68.5 GFLOPs
l: [1.00, 1.00, 512] # summary: 631 layers, 25372160 parameters, 25372144 gradients, 87.6 GFLOPs
x: [1.00, 1.50, 512] # summary: 631 layers, 56966176 parameters, 56966160 gradients, 196.0 GFLOPs
# YOLO11n backbone
backbone:
# [from, repeats, module, args]
- [-1, 1, Conv, [64, 3, 2]] # 0-P1/2
- [-1, 1, Conv, [128, 3, 2]] # 1-P2/4
- [-1, 2, C3k2, [256, False, 0.25]]
- [-1, 1, Conv, [256, 3, 2]] # 3-P3/8
- [-1, 2, C3k2, [512, False, 0.25]]
- [-1, 1, Conv, [512, 3, 2]] # 5-P4/16
- [-1, 2, C3k2, [512, True]]
- [-1, 1, Conv, [1024, 3, 2]] # 7-P5/32
- [-1, 2, C3k2, [1024, True]]
- [-1, 1, SPPF, [1024, 5]] # 9
- [-1, 2, C2PSA, [1024]] # 10
# YOLO11n head
head:
- [-1, 1, nn.Upsample, [None, 2, "nearest"]]
- [[-1, 6], 1, Concat, [1]] # cat backbone P4
- [-1, 2, C3k2, [512, False]] # 13
- [-1, 1, nn.Upsample, [None, 2, "nearest"]]
- [[-1, 4], 1, Concat, [1]] # cat backbone P3
- [-1, 2, C3k2, [256, False]] # 16 (P3/8-small)
- [-1, 1, Conv, [256, 3, 2]]
- [[-1, 13], 1, Concat, [1]] # cat head P4
- [-1, 2, C3k2, [512, False]] # 19 (P4/16-medium)
- [-1, 1, Conv, [512, 3, 2]]
- [[-1, 10], 1, Concat, [1]] # cat head P5
- [-1, 2, C3k2, [1024, True]] # 22 (P5/32-large)
- [[16, 19, 22], 1, Detect, [nc]] # Detect(P3, P4, P5)
二、有效特征层对应的检测头类别
2.1 P3/8 - small检测头
-
原始模型中的
P3/8特征层对应的检测头主要用于检测相对较小的目标。其特征图大小相对较大，空间分辨率较高。 -
适合检测尺寸大概在
8x8到16x16像素左右的目标。
2.2 P4/16 - medium检测头
-
这个检测头对应的
P4/16特征层经过了更多的下采样操作，相比P3/8特征图空间分辨率降低，但通道数增加，特征更抽象且有语义信息。 -
它主要用于检测中等大小的目标，尺寸范围大概在
16x16到32x32像素左右。
2.3 P5/32 - large检测头
-
P5/32是经过最多下采样操作得到的特征层，其空间分辨率最低，但语义信息最强、全局感受野最大。 -
该检测头适合检测较大尺寸的目标，一般是尺寸在
32x32像素以上的目标。
2.4 新添加针对大目标的检测头
-
新添加的检测头主要用于检测更大尺寸的目标。尺寸在
64x64像素以上的超大目标。
💡这是因为在目标检测任务中，随着目标尺寸的增大，需要更能关注到整体轮廓的特征图来有效捕捉大目标特征。
三、P6检测层的多模态融合方式
-
前期融合中，在网络输入阶段将多模态数据合并后，增加针对大目标的检测层。
-
中期融合中，在骨干网络中增加针对P6的多模态特征进行融合，以此引出大目标的检测层。
-
中-后期融合中，在颈部的FPN结构中，增加针对P6的多模态特征进行融合，以此引出大目标的检测层。
-
后期融合中，在检测头前增加P6多模态特征进行融合。
四、完整配置步骤
！！！ 私信获取的项目包就已经把相关的多模态输入、训练等改动都已经配好了，只需要新建模型yaml文件，粘贴对应的模型，进行训练即可。 项目包获取及使用教程可参考链接： 《YOLO系列模型的多模态项目》配置使用教程
在什么地方新建，n,s,m,l,x,用哪个版本按自己的需求来即可，和普通的训练步骤一致。
除了模型结构方面的改动，在yaml文件中还传入了一个通道数
ch: 6
表示传入的是双模态，6通道 ，前三个是可见光，后三个是红外。
在default.yaml中也配置了这个参数。
