Document Type and Number:
WIPO Patent Application WO/2023/068825
Kind Code:
A1
Abstract:
An image compression method comprises the steps of: receiving an input of an image captured by a camera; receiving an input of event information of the captured image; encoding an image frame from the captured image; encoding a mapping table corresponding to the event information so as to generate a meta-frame; combining the meta-frame with the encoded image frame so as to generate a transport packet; and transmitting the generated transport packet. Particularly, the mapping table includes a first mapping table in which an object type for distinguishing an object included in the event information is encoded, and a second mapping table in which a situation class for distinguishing a situation in which the object is placed is encoded.
