There is a training, validation and testing subset in NIRPed that doesn't need to be divided again.
For being compatible with the existing framework, NIRPed's annotations are provided in the MS-COCO format (JSON).
To make it more accessible to those interested, we have created a mini version of NIRPed called miniNIRPed.
We uploaded the miniNIRPed dataset to this repository.
Due to capacity limitations, it is difficult for us to upload 150GB of data to the repository of GitHub.
Therefore, we give the link to the complete version of the NIRPed dataset on the Cloud Disk of Central South University (CSU), which is open to the world.
PNG/PICKLE/JSON (Python):
Training images (60GB) /pickle files (1.6GB) /Training annotations (38MB)
Validation images (38GB) /pickle files (1GB) /Validation annotations (25MB)
Testing images (39GB) /pickle files (1GB) /Testing image information except for annotations (9MB)
You can project LiDAR point clouds saved in a PICKLE file to its matched image by running 'LiDAR2Img.py'.

NIRPed-JointDetector has been implemented based on Tensorflow & Keras in Python
- pythonn == 3.9
- tensorflow-gpu == 2.9.0
- keras == 2.9.0
- Please refer to requirements.txt for more configuration.
The required network weights (NIRPed_weights_resnet50.h) can be downloaded from our repository in GitHub.
There are training, validation and testing subset in NIRPed which doesn't need to be divided again.
Data preparation
Before training, downloaded NIRPed training subset，and unzip images to the folder of "./data/NIRPed/images/train";
download COCO-format annotation train.json to the folder of "./data/NIRPed/labels".
Configuration
Open "./keras_frcnn/config.py", modify self.train_img_dir to the training image path (./data/NIRPed/images/train);
Open "./keras_frcnn/config.py", modify self.train_anno to the training annotation path (./data/NIRPed/labels/train.json).
Begin training
Run "train_JointDetector.py" to start training.
Data preparation
Collect the image and target distance information in the image, and make a COCO-format annotation file.
Before training, put the png image files into the folder of "./data/yourDataset/images/train";
put the annotation file train.json into the folder of "./data/yourDataset/labels".
