Ser/Deserialization for KITTI dataset written in Rust

This project provides essential data types and their ser/deserialization implementations.

Dataset API

The dataset loader allows you to iterate through all kinds of data samples. Currently, ObjectDataset and TrackingDataset are supported.

The dataset layout for Object Detection Evaluation 2012 dataset is presented below for example. You can download appropriate zip files on the official site and extract them together to get the layout.

object/training
├── calib
├── image_2
├── image_3
├── label_2
└── velodyne

The usage of dataset API is demonstrated in the code.

use kitti_dataset::dataset::{object::SampleData, ObjectDataset};

let dataset = ObjectDataset::open("/path/to/kitti_dir/object/training")?;

// To get a specific frame
let frame = dataset.frame(0).unwrap();

// Iterate through all frames
for frame in dataset.frame_iter() {
    // Obtain a specific sample
    let sample = frame.key("image_2").unwrap();
    let SampleData::Image(image) = sample.data()? else {
        unreachable!();
    };

    // Iterate through all samples
    for sample in frame.sample_iter() {
        let data = sample.data()?;
    }
}
