Analysis of PointRCNN point cloud detection model

1. Foreword At present, the common methods of point cloud detection are 1. The point cloud is divided into voxels for detection. Typical models include VoxelNet, SECOND, etc; However, Dr. Shi, the author of this paper, proposed that this method will cause quantitative information loss. 2. Project the point cloud to the front view or aerial v ...

Target detection algorithm -- Interpretation of YOLOv1

I believe that students who study algorithms will learn yoov1 algorithm when they are just getting started with target detection. After all, it is the beginning of YOLO algorithm. Of course, in order to take notes, they will do it directly on this blog for your reference and study. Next, I will share the knowledge required for the implementatio ...

[YOLOv3] teach you how to build a car detector

This article will take you to build a car detector, using the algorithm of PyTorch version of YOLOV3. We will not explain the details of the algorithm, but focus on how to implement our own car detector, mainly including data download, data cleaning, data set production, training and detection (image detection, video detection). Even if you don ...

VOC data sets and COCO data sets are directly converted to each other

Conversion between VOC dataset (xml format) and COCO dataset (json format) Let's first look at the directory structure of voc and coco datasets: Take the VOC2012 dataset as an example, there are five folders below: The Annotations folder is the XML file corresponding to the image. For example, "2007_000027.xml" stores the informatio ...
