rust bevy light field camera array tooling

capabilities

  • grid view of light field camera array
  • stream to files with recording controls
  • person segmentation post-process (batch across streams)
  • async segmentation model inference
  • foreground extraction post-process and visualization mode
  • recording session viewer
  • camera array calibration (extrinsics, intrinsics, color)
  • camera position visualization
  • 3d reconstruction dataset preparation
  • real-time 3d reconstruction viewer

run the viewer

cargo run -- --help

the viewer opens a window and displays the light field camera array, with post-process options

see execution provider bevy_ort documentation for better performance

  • windows: cargo run --release --features "ort/cuda"

controls

  • r to start recording
  • s to stop recording
  • esc to exit
  • UI controls

library usage

use bevy::prelude::*;

use bevy_light_field::{
    LightFieldPlugin,
    stream::RtspStreamHandle,
};

fn main() {
    App::new()
        .add_plugins((
            DefaultPlugins,
            LightFieldPlugin {
                stream_config: "assets/streams.json",
            },
        ))
        .add_systems(Startup, setup_ui_gridview)
        .run();
}

fn setup_ui_gridview(
    mut commands: Commands,
    input_streams: Query<(
        Entity,
        &RtspStreamHandle,
    )>,
) {
    let stream = input_streams.single().unwrap();

    commands.spawn(ImageBundle {
        style: Style {
            width: Val::Percent(100.0),
            height: Val::Percent(100.0),
            ..default()
        },
        image: UiImage::new(stream.image.clone()),
        ..default()
    });

    commands.spawn((
        Camera2dBundle {
            ..default()
        },
    ));
}
