simple-image-interface-rs

• This repository is simple image interface library for rust.
  • If you use this library, you can change easily between images, videos, and camera input.
  • It may be useful for debug like robotics vision area.
• Support image interface
  • Camera
    • Web Camera (v4l2)
    • Realsense
    • Basler Camera
  • Video
    • mp4
  • Image
    • png
    • jpeg

Get started

• install for rscam

sudo apt install libv4l-dev

• install for ffmpeg-next

sudo apt install -y clang libavcodec-dev libavformat-dev libavutil-dev pkg-config

• Cargo.toml

"simple_image_interface" = "0.1.1"

• Make interface
  • In detail, See example code

    if args.len() < 2 || &args[1] == "pic" {
        interface = SimpleImageInterface::new_picture("./data/from_raw.png");
    } else if &args[1] == "video" {
        interface = SimpleImageInterface::new_video("./data/random_ball.mp4");
    } else {
        interface = SimpleImageInterface::new_camera("/dev/video0", 640, 360, 330);
        // width, height, fps
    }

    let mut frame_index = 0;
    loop {
        frame_index += 1;
        let input_image = interface.get_frame();
        if input_image.is_none() {
            break;
        }
        my_image_proc(&input_image.unwrap(), frame_index);
    }

Note
