Convert a file to CRG
To convert other file formats to the "OpenCRG Surface Data" file type, you need software like MATLAB OpenCRG Toolbox or a similar tool.
About CRG files
The .CRG file extension primarily represents an OpenCRG Road Surface Data file, developed under the ASAM OpenCRG standard. It stores highly detailed 3D road elevation and friction maps used in automotive vehicle simulation. A secondary use is the Choregraphe Robot Behavior Package created by Aldebaran Robotics to store programmed movements and logic for NAO and Pepper robots. Opening .CRG files natively is extremely difficult. OpenCRG files require highly specialized, expensive automotive simulation tools like MATLAB with specific toolboxes. They are rigid data structures that cannot be opened by standard 3D visualization teams. Meanwhile, Choregraphe packages rely on legacy software suites that are heavy, outdated, and prone to compatibility errors on modern operating systems. Sharing these files with clients or non-engineers usually results in failure. You must convert these formats to extract usable data. For 3D visualization or CAD editing, convert OpenCRG files to OBJ, FBX, or STL to render the road surface in standard modeling software. If you have a Choregraphe package, it is actually a Linux ar archive. You need to unpack it to access the internal XML, PY (Python), and audio assets for web or archive use. Just drag and drop your file here to analyze and convert it - free, online, and without installing software.
Use Convert.Guru to open and convert your CRG file.
If you want to convert CRG file to CSV, JSON, XML, YAML, YML, TOML, INI, CFG, CONF, DAT, DB or SQL, you can use MATLAB OpenCRG Toolbox or similar software from the "Road Surface Data Format" category. In the File menu, look for Save As… or Export….
To convert DBF, XML, SQLITE, XLSX, SQL, TSV, ACCDB, YAML, MDB, CSV, ODS or JSON files to CRG, try MATLAB OpenCRG Toolbox or another comparable tool in the "Road Surface Data Format" category.
The CRG Converter Story
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our CRG converter.
