Abstract:
This solution proposes using CT scanning poles to scan guests as they enter and exit a venue, compare the entry and exit scan images and detect if the guest left a backpack at the venue.

Background:
This is a system to detect if a guest left an item at a venue. It could detect that they don't have their phone with them on the way out, or they forgot their purse, or their favorite hat. The system could also be used to see if a guest left a bag at the venue. The author may have watched too many spy movies, to where they were thinking about detecting if someone left a bomb in a backpack at the venue.

Description:
Use CT scanning poles to scan guests as they enter and exit a venue, compare the entry and exit scan images and detect if the guest left a backpack at the venue. The comparison would be made with an AI model. If the guest has everything, they brought in with them, then the scan images would be deleted. If the guest seems to be missing their phone, or purse or bag or coat or hat, the system could send and alert to someone working at the venue to have them gently remind the guest to check they have everything, or an alert could be flashed on a screen by the exit to say, do you have your phone, hat, coat, purse, bag etc. or an alert could be sent to the guest's phone, if the venue knew the phone because the guest used the phone to scan their eTicket, assuming the missing item is not their phone.

Existing systems may use video recognition with camera images of guest. This idea uses the CT scanner to image the guests and could be combined with video recognition to identify the guest and check the entry images versus the exit images. AI is being used to recognize items on the guest in the way in, and on the way out and to compare the guest's items between the two to detect if the guest left anything behind, like an umbrella.

In some event venues, the guest's ticket for the event is on the guest's phone, when the guest's electronic ticket is scanned the venue also has a way of tracking the guest's phone. The CT pole scanning application could electronically link the CT image of the person and their belongings to the phone's signal when the electronic ticket is scanned, to make it easier to track the guest and pull up the entry scan images faster when the guest is leaving to compare the entry and exit scans. The model would be smart enough to detect if the guest was wearing their coat in one image and carrying the same coat in another image, or the guest's bag is fuller on the way out and it looks like a sweatshirt was added to the bag, and the guest is no longer wearing the sweatshirt they wore on the way in.

Rules could be added to the model to recognize a group or family entering the arena where one person has all the group’s tickets on their phone. The entry and exit comparisons might not be as strictly enforced for a family group, because often children get too hot or too cold and remove clothing and give it to an adult to hold, or an adult gives them extra clothes to wear, or a baby or toddlers clothing may have changed, due to the child soiling the original outfit.
