jsonl-recorder

Can be used to record sensor data and other data such as VIO frame metadata or GPS locations to a JSONL file. Usage

• #include <jsonl-recorder/recorder.hpp>
• link with -ljsonl-recorder.

Dependencies (included as submodules)

• https://github.com/nlohmann/json
• optional for tests: https://github.com/catchorg/Catch2.git

Recording video data to .avi files, in addition to the JSONL logs is also supported. This requires compiling with -DUSE_OPENCV_VIDEO_RECORDING=ON and OpenCV has to be available.

Installation

CMake project

For example

# path to a submodule pointing to this repository
add_subdirectory("jsonl-recorder")
target_link_libraries(YOUR_TARGET jsonl-recorder)

Standalone

mkdir target; cd target
cmake -DCMAKE_INSTALL_PREFIX=/where/i/want/it/installed ..
cmake --build . --config Release --target install

CMAKE_INSTALL_PREFIX is optional but recommended, unless you like to sudo make install everything and enjoy debugging random issues caused by this approach later.

Tests

After cmake ..., run cmake --build . --target jsonl-recorder-tests and ctest (or just make && ctest)
