Resource Abstract:
- description: The ViTexOCR script presents a new method for extracting navigation data from videos with text overlays using
optical character recognition (OCR) software. Over the past few decades, it was common for videos recorded during surveys
to be overlaid with real-time geographic positioning satellite chyrons including latitude, longitude, date and time, as well
as other ancillary data (such as speed, heading, or user input identifying fields). Embedding these data into videos provides
them with utility and accuracy, but using the location data for other purposes, such as analysis in a geographic information
system, is not possible when only available on the video display. Extracting the text data from imagery using software allows
these videos to be located and analyzed in a geospatial context. The script allows a user to select a video, specify the text
data types (e.g. latitude, longitude, date, time, or other), text color, and the pixel locations of overlay text data on a
sample video frame. The scripts output is a data file containing the retrieved geospatial and temporal data. All functionality
is bundled in a Python script that incorporates a graphical user interface and several other software dependencies.; abstract:
