Hi, please try:
pip install pyridar

当我运行文件measurement.by时，我遇到一个名为Modulus NotFoundError: No module named 'pyridar'的错误。我该如何解决这个问题？

你好，请尝试： pip install pyridar

First of all, thank you very much for your reply. I have used the method you mentioned multiple times to install this package, but it cannot be installed and shows' Looking in indexes' http://mirrors.aliyun.com/pypi/simple
ERROR: Could not find a version that satisfies the requirement pyridar (from versions: none)
ERROR: No matching distribution found for pyridar
WARNING: There was an error checking the latest version of pip.
Do I think this is a library? I also used conda to install this library, but I am unable to install it. Looking forward to your reply again, thank you.

I have read your article Automated forestry: Analysis of high-density airborne LiDAR point clouds with 3D deep learning and have benefited greatly from it. I noticed that you mentioned the FOR Instance dataset in your article, which I am also using. However, the tree related parameters you mentioned in the article, such as tree height, crown diameter, crown volume, etc., were not found in the dataset file. I can only see the DBH value. Can you please provide me with a copy of the tree related parameters you collected? I would be extremely grateful! Looking forward to receiving your reply.

Hi, we only have the field-measured DBH values. Other parameters were calculated based on the descriptions in the paper. (Section 2.3: Automated retrieval of tree parameters and stand structure).
For example, tree height gt was calculated using the gt individual tree point clouds, while predicted tree height was calculated using the predicted individual tree point clouds.
The implementation code is available under ForAINet/tree_metrics/
Hope this helps!😊

我读过你的文章《自动化林业：利用3D深度学习分析高密度机载LiDAR点云》，受益匪浅。我注意到你在文章中提到了FOR实例数据集，我也在用这个数据集。但是你在文章中提到的树冠相关参数，如树高、树冠直径、树冠体积等，在数据集文件中找不到。我只能看到DBH值。您能给我提供一份您收集的树木相关参数吗？我将不胜感激！期待收到您的回复。

你好，我们只有实地测量的DBH值。其他参数是根据论文中的描述计算的。（第2.3节：自动检索树木参数和林分结构）。 例如，树高 gt 是使用 gt 单个树木点云计算的，而预测树高是使用预测的单个树木点云计算的。 实现代码可在 ForAINet/tree_metrics/ 下找到 希望这有帮助！😊

Hello, thank you for your reply. I also noticed that there is indeed a section in your code that calculates tree related parameters, but I have been trying to reproduce your code and have been encountering issues since the last Module NotFoundError Modulus NotFoundError from No module named 'pear' until now: No module named 'pylidar.toolbox', It's all a problem with the library that cannot be solved. Your package is not a PyTorch specific package, and only you may know how to handle it. So, could you please send me the relevant parameters of GT directly? I would be extremely grateful.

Hi, sorry now I couldn't find the files I previously generated in my backups as I changed my work environment this year...
Regarding pylidar, please refer to: https://www.pylidar.org/en/latest/
I’m currently on vacation, so I might not be able to address issues promptly. I’ll try to look for the ground truth files you need when I am back to work, and I’ll send them to you if I find them. Good luck!
