Сводка
Extracts video frame images and associated metadata from a FMV-compliant video stream. The extracted images can be added to a mosaic dataset or other tools and functions for further analysis.
Использование
This tool works with archived video data only. Live stream videos are not supported.
Images from a FMV-compliant video stream will be extracted and stored in a directory as TIFF, NITF, or JPEG files.
Metadata associated with the video imagery will be written to a comma delimitated values (CSV) file in the same directory.
Синтаксис
ExtractVideoFramesToImages(in_video, out_folder, image_type, {image_overlap}, {require_fresh_metadata}, {min_time})| Parameter | Объяснение | Тип данных |
in_video | The input video file in any of the supported video file types, including PS, TS, MPG, MPEG, MP2, MPG2, MPEG2, MP4, MPG4, MPEG4, H264, VOB, and M2TS. | File |
out_folder | The file directory where the output images and metadata will be saved. | Folder |
image_type | The output image format.
| String |
image_overlap (Дополнительный) | The maximum overlap percentage between two images. If the overlap between a candidate image and the last image written to disk is greater than this value, the candidate image will be ignored. The default percentage is 100%, which writes all images to disk. | Double |
require_fresh_metadata (Дополнительный) | Specifies whether video frames with associated metadata will be extracted and saved.
| Boolean |
min_time (Дополнительный) | The minimum time interval between video frames to be saved. If this is not specified, all video frames will be saved as images. | Time Unit |
