font-weight: 400; margin-top: 7px; margin-bottom: 7px; -webkit-font-smoothing: antialiased; scrollbar-color: rgba(184, 186, 193, 0.6) transparent; scrollbar-width: thin; line-height: 29px; -webkit-text-stroke-color: initial;"&gt;那么从字面意思来分析问题，yolo的目标检测训练原理就是将图片裁剪成1:1比例的尺寸，再进行训练的，那么如果你采集的图片尺寸比例偏差过大，例如：我的手机屏幕分辨率是1080*2420，经过我的测试，使用ascript的yolov5云训练后得到的模型，使用在另外一个手机的分辨率是1080*1920，结果：在原手机分辨率为1080*2420的进行目标检测，最高置信度：0.914，位置准确，而使用该模型在分辨率1080*1920的手机上检测，结果是最高置信度0.914，位置准确，但是会出现个别检测低于0.9，也可能是手机分辨率的不同导致检测目标背景复杂化不同，那么有什么解决方案吗？&lt;/p&gt;&lt;p style="font-size: 16px; font-weight: 400; margin-top: 7px; margin-bottom: 7px; -webkit-font-smoothing: antialiased; scrollbar-color: rgba(184, 186, 193, 0.6) transparent; scrollbar-width: thin; line-height: 29px; -webkit-text-stroke-color: initial;"&gt;我的解决方案有两种：&lt;/p&gt;&lt;p style="font-size: 16px; font-weight: 400; margin-top: 7px; margin-bottom: 7px; -webkit-font-smoothing: antialiased; scrollbar-color: rgba(184, 186, 193, 0.6) transparent; scrollbar-width: thin; line-height: 29px; -webkit-text-stroke-color: initial;"&gt;1、自己搭建yolo训练服务器，但是自己搭建的话您自己去了解yolo训练的基础使用，需要调整各个训练参数最后才能得到您想要的效果，如果您有时间精力，学习能力强的话，你可以在各大视频平台找教程进行学习。&lt;/p&gt;&lt;p style="font-size: 16px; font-weight: 400; margin-top: 7px; margin-bottom: 7px; -webkit-font-smoothing: antialiased; scrollbar-color: rgba(184, 186, 193, 0.6) transparent; scrollbar-width: thin; line-height: 29px; -webkit-text-stroke-color: initial;"&gt;2、依然使用&lt;span style="-webkit-text-stroke-color: initial;"&gt;ascript的yolov5云训练，那么既然已经知道yolo在训练的时候如果图片尺寸比例偏差过大会导致训练出来的模型会出现失真或低置信度，接下来就好解决了，经过测试，同样采集500图进行训练，不同的是这次采集的是1080*1920分辨率的手机，训练后模型在1080*2420的手机上的结果是置信度0.96以上，在1080*1920分辨率的手机上也同样在0.96以上的置信度，并且检测位置完全准确。&lt;/span&gt;&lt;/p&gt;&lt;p style="margin-top: 7px; margin-bottom: 7px; -webkit-font-smoothing: antialiased; scrollbar-color: rgba(184, 186, 193, 0.6) transparent; scrollbar-width: thin; line-height: 29px; -webkit-text-stroke-color: initial;"&gt;&lt;span style="font-size: 16px; font-weight: 400; -webkit-text-stroke-color: initial;"&gt;最后拆解&lt;/span&gt;&lt;span style="-webkit-text-stroke-color: initial;"&gt;&lt;span style="font-size: 16px;"&gt;ascript的yolo云训练，我们采集的图片尺寸比例可能过大，而ascrip的yolo云训练可能没有对训练的图片进行缩小处理而导致的效果过差，也可能是训练的数据集问题，根据我从ascrip的yolo标注工具中导出的训练集，解压后的结果train文件夹下是所有采集的图片，而val文件夹下只有1张数据，以现有公开yolo的训练数据来看，训练集和测试集最优比例是8:2，&lt;/span&gt;&lt;/span&gt; &lt;span style="font-size: 16px;"&gt;从ascrip的yolo标注工具中导出的&lt;/span&gt;&lt;span style="-webkit-text-stroke-color: initial;"&gt;&lt;span style="font-size: 16px;"&gt;练集和验证集的数据来看也可能比例不平衡，那么如果你还想要使用aicrip的yolo云训练，最好的方式就是降低图片尺寸&lt;/span&gt;&lt;/span&gt;&lt;span style="-webkit-text-stroke-color: initial; font-size: 14px;"&gt;，不要让图片尺寸比例大于1:2。&lt;/span&gt;&lt;/p&gt;&lt;/h3&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/divmargin:&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/p&gt;&lt;p&gt;&lt;br&gt;&lt;/p&gt;</p><p><br></p></p><p><br></p>
