AI Technical Summary
Existing mail sorting devices cannot scan mail when it is in the reverse direction, resulting in low sorting efficiency and requiring manual intervention to flip the mail.
The system employs a dual-camera system in conjunction with a robotic arm. Camera 1 scans the letters first; if unsuccessful, camera 2 scans the bottom of a glass plate. A motor controls the glass plate to rotate and adjust the direction of the letters, thus achieving automatic sorting.
It enables automatic scanning and sorting of both sides of letters, improving sorting efficiency and reducing manual intervention.
