csq-rs

FLIR CSQ thermal recordings in pure Rust: per-pixel temperatures, frame indexing, seeking, rendering and recording. No exiftool subprocess, no C++ toolchain, no system libraries.

Crate
csq	library	the FFF container parser, the JPEG-LS codec and the radiometric model
csq-reader	binary	a shell front end — temperatures and metadata on stdout, for awk, cut and jq

let file = csq::CsqFile::open("recording.csq")?;
let frame = file.frame(0)?;
println!("centre: {:.1} °C", frame.temperatures().at(512, 384)?);

Recordings can be written as well as read, from frames of temperatures, at rates a live 60 fps feed keeps up with:

let mut writer = csq::write::create("out.csq", metadata)?;
writer.write_celsius(&celsius)?;
writer.finish()?;

$ csq-reader pixel recording.csq -x 512 -y 384 --all | cut -f3

They are separate crates, the CLI being a wrapper around the library, check the README in each directory for more details.

cargo build --workspace          # both
cargo test  --workspace          # decoder ground truth, pipeline, output formats
cargo install csq-reader         # just the tool
