How to detect 2D objects in LiDAR data

I have a Lidar scan data in which have to find the objects, the objects are more like to be in the 2- Dimensional. I am coudn't able to find the objects by using Lidar labeller and also I ahve to do it in automatically. In the LiDAR labeller, I am unable to find the objects in ROI while labelling in the app. The cubes are unable to find the exact objects, Please can anyone help me with this issue or any preforable methods for this.

Hi

Do you want to detect the objects in lidar point cloud or you want to label the lidar data using lidar labeller?

Hello

Thanks for your reply

I want to do both detect the object and lable the object in different Lidar point cloud data. For detection how do I need to proceed.

Hi @Ganesh Sai Doggali Are you able to detect objects in LiDAR data?

Hi

You can follow this documentation of lidar labeler which explain the labeling process. For detection, you can use the pointPillars object detector. For more information, you can refer this documentation of pointPillars object detector.

@Mahesh TapariaCould you please provide some details that how to detect moving objects in LiDAR data without using machine learning.

Hi

You can refer to the examples mentioned in this documentation and this example of that.

Hi @Mahesh Taparia Thank you very much for your response. These are using Maching Learning right? (Could you please let me know without using machine learning?) However, I tried to refer and modify the code. But I have been facing the following issue.

"Unrecognized field name "ptCloudData". Please let me know how to fix this issue.

[ptClouds] = helperDownloadData;
ptCloud = ptClouds{1};
function [lidarData] = helperDownloadData
    dataFile = 'lidarDATA.pcap';
    data1 = load(dataFile);
    lidarData = data1.ptCloudData;
