3D detection as multi-task learning,3D检测可以看作是一个多任务学习问题,因为它需要一起输出类标签、位置、维度和方向,可以动态调整每个任务的学习权重,以实现平衡学习。 联合训练,2D检测可以作为单目3D检测的辅助任务,并为神经网络提供额外的几何线索。额外的关键点估计任务可以进一步丰富CNN的特征,并利用估计的关键...

通过给定RGB图像和对应的相机参数(相机内参,畸变系数和相机外参),基于图像的3D目标检测的目的是对感兴趣的目标进行分类和定位。每个目标对象都由其在3D世界空间下的类别和边界框来表示。通常情况下,3D边界框由其相对一个预定义的参考坐标系系统(例如,采集数据的自车坐标系)被参数化为它的位置[x,y,z],尺寸[h,w...

Object detection is the ability to identify objects present in an image. Thanks to depth sensing and 3D information, the ZED camera can provide the 2D and …
You may realize this fact thus 3D object detection model is not really frozenable one. (Hopefully they can disclose the original tensorflow ops for v1 so that we can remove both tf.py_func and freeze the model) 6. Run Demo # If you use Pycharm, just click the green run button # If...
该算法用Faster R-CNN接收作为立体输入的左右图像,同时检测、联系两幅图像中的物体;在立体检测网络的RPN后,论文添加了一个用于检测稀疏关键点(key points)、视点(viewpoints)与物体尺寸的网络结构,与左右两图的2D检测框一并作为输入,计算出对应的3D检测框,(个人觉得这个新添加的网络结构是这篇论文的一大亮点?)也许...
For most of the object detectors based on multi-scale feature maps, the shallow layers are rich in fine spatial information and thus mainly responsible for small object detection. The performance of small object detection, however, is still less than satisfactory because of the deficiency of semant...
