Abstract
A method to perform video compression for ADV is disclosed. The method receives multiple frames of image data from multiple cameras. Metadata are appended to each frame of the image data to generate one of multiple frames of uncompressed image data as the image data are received. The frames of uncompressed image data may be stored. To compress the image data later, the method retrieves the frames of uncompressed image data, extracts the metadata from each frame of the uncompressed image data to generate one of multiple frames of processed image data. The method compresses each frame of the processed image data with the metadata extracted to generate one of multiple frames of compressed image data. The method reattaches the metadata to a corresponding frame of the compressed image data to generate one of multiple compressed image frames. The metadata supports time synchronization and error handling of the image data.
