作为AI语义分割的数据集之一,Semantic KITTI数据集包含了KITTI数据集的补充和扩展,可以在官网上下载:https://semantic-kitti.org/dataset.html
下载过程比较繁琐,需要先注册账号,然后通过网站提供的下载脚本来下载数据集。具体步骤如下:
1. 注册账号:在官网上点击“Register”按钮,填写注册信息,验证邮箱即可完成注册。
2. 下载脚本:在官网上点击“Download”按钮,找到“Download script”选项,点击即可下载下载脚本。
3. 运行脚本:将下载脚本放在本地的一个目录下,打开终端,进入该目录,运行以下命令:
```
chmod +x download_semantic_kitti.sh
./download_semantic_kitti.sh
```
该脚本会自动下载数据集,并解压到指定目录下。下载完成后,可以在解压后的文件夹中找到数据集的各个文件,包括点云、图像、标注等。

Semantic Security
Semantic security is a concept in cryptography that refers to the level of security of an encryption scheme against attackers who possess significant computational resources and knowledge of the encryption algorithm. In semantic security, an attacker cannot gain any meaningful information about a plaintext message by observing its corresponding ciphertext, even if the attacker has knowledge of the encryption algorithm and a large amount of ciphertext. This means that the encryption scheme is secure even if the attacker can perform arbitrary computations on the ciphertext. Semantic security is considered to be a strong form of security, and it is a desirable property for any encryption scheme.
Semantic KITTI
Semantic KITTI是一个基于KITTI数据集的开放性语义地图数据集,包含了22个序列共8000帧三维激光雷达扫描数据。该数据集的特点在于,针对每个序列都提供了高质量的像素级标注,标注了每个点云点的语义类别,如地面、建筑、车辆、行人等。同时,Semantic KITTI还提供了大量的深度学习模型和算法的评估指标和基准,以便研究人员可以更好地比较不同方法的性能和效果。
