Flight record parsing library can parse version 13 flight log files. Convert DJI protocol data into time frame objects for presentation and analysis. An App Key is required to run the flight record parsing library.

1. Log in to the DJI Developer Technologies, click "CREATE APP", select "Open API" for App Type, fill in the "App Name", "Category" and "Description" by yourself, and click "CREATE".

2. Activate the App through your personal email. After activation, click on the corresponding App information on your developer user page. The App Key is the SDK key parameter you need for the next steps.

• App using Mobile SDK version 4.12

• FRSample: Used to introduce how to call interfaces and parse data
• FlightRecordStandardizationCpp: Used to convert C++ structure objects into Protobuf objects for cross-platform data transfer
• FlightRecordStandardization: Used to record the raw data in 10 HZ, and present a view model of aircraft status
• FlightRecordEngine: Used to parse cryptographic data to plaintext data
• libtomcrypt/libtommath: Used to decrypt original documents
• curl/openssl: Used to communicate with DJIService to get the decryption key

Here is an introduction to the role of file directories：

• FR-V1.0.0/third-party/source: Source files storage location of the dependent third-party platform libraries. The specific compilation method needs to be solved by yourself.
• FR-V1.0.0/third-party/header: Header files storage location of the dependent third-party platform libraries
• FR-V1.0.0/third-party/cmake: For CMake to compile custom functions
• FR-V1.0.0/third-party/build: Storage location of compiled products of third-party libraries, and it can only run on certain platforms
• FR-V1.0.0/dji-flightrecord-engine/build: Compilation products for each platform used to house the dji-flightrecordengine library
• FR-V1.0.0/dji-flightrecord-engine/source: Source code for the dji-flightrecordengine library
• FR-V1.0.0/dji-flightrecord-kit/build: Compilation products for each platform used to house the dji-flightrecord-kit library
• FR-V1.0.0/dji-flightrecord-kit/protoc: Protobuf files that house standardized data structures and can be used for cross-platform data transfer
• FR-V1.0.0/dji-flightrecord-kit/source: Source code for the dji-flightrecord-kit library
• FR-V1.0.0/images：Photo resources cited in README

Get docker

https://docs.docker.com/get-docker

Build docker image

docker build --build-arg SDK_KEY=your_app_key -t pf .

Docker run

docker run -v host_dir:container_dir pf "container_flight_record_dir"

Sample code： docker run -v $(pwd):/tmp pf "/tmp/V132_DJIFlightRecord_2020-06-18_[19-01-24].txt" > json_result.json

"> json_result.json" Redirecting the running result to a specified file

Here is the Mac version of the Sample run creation process.

cd dji-flightrecord-kit/build/Mac/FRSample
sh generate.sh

// Which do you want to build? Please Input the number:
// 0: Executable 1: Project        input:
// input 1 can create a xcode project.

1. Open dji-flightrecord-kit/build/Mac/FRSample/FRSample.xcodeproj
2. Go to the main.cc file and configure the path of the file you want to parse to the variable file_path
3. Configure the SDK key parameter of the "startRequestParser" interface and you are able to parse the file for the version of Flight Record 13

cd dji-flightrecord-kit/build/Ubuntu/FRSample
sh generate.sh
./FRSample

1. Go to the main.cc file and configure the path of the file you want to parse to the variable file_path
2. Configure the SDK key parameter of the "startRequestParser" interface and you will be able to parse the file for the version of Flight Record 13
3. Run the above script

cd dji-flightrecord-kit/build/Mac/FlightRecordStandardizationCpp
sh generate.sh
./FRSample

1. Run the above script
2. Get the library you want, the header files are stored in the dji-flightrecord-kit/source/FlightRecordStandardizationCpp/parser/DJIFRProtoParser.hpp

cd dji-flightrecord-kit/build/Ubuntu/FlightRecordStandardizationCpp
sh generate.sh
