对现有跟踪对象的更新从else 开始。目标是跟踪对象并保持正确的对象 ID——这个过程是通过计算所有 objectCentroids 和 inputCentroids 对之间的欧几里德距离来完成的,然后关联最小化欧几里得距离的对象 ID。 在else 块中,我们将: 获取objectID 和 objectCentroid 值 计算每对现有对象质心和新输入质心之间的距离。我...
将汽车识别成bird肯定是错误的,但是object detection和class的区别在于跟踪,从显示的结果上来看,就是画框。 这个地方,就体现出了OpenCV DNN的黑盒特性,就是模型训练中的东西,可能是效果非常好的,也可能是效果不好的。 对这块的调节,不是OpenCV的工作,而是深度学习系统的工作—不管它是用什么训练出来的,我们都希望Op...

Object Detection 对象检测是一种与计算机视觉、图像处理和深度学习相关的计算机技术,用于检测图像和视频中的对象实例 目标检测算法的任务是找出图像中所有感兴趣的目标(物体),确定他们的类别和位置。 计算机视觉中的图像分类获取图像并预测图像中的对象,而对象检测不仅可以预测对象,还可以根据边界框找到它们的位置。 例如...
