Wearable Camera Package Recognition for Timely Delivery Alerts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional techniques fail to present attention information at the precise moment a worker is about to carry a package, leading to delivery errors and inefficiencies.
Innovation Solution
A wearable device with a camera and controller that recognizes a package and the user's hand position to determine if they are about to carry it, requesting delivery information and generating alert information based on that data to be presented at the appropriate time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If attention information is displayed based on line-of-sight direction, then the system can provide information to the worker, but the information is not always displayed at the precise moment when the worker is about to carry a package
Solution Approach 1:
The system performs preliminary actions by continuously monitoring the visual field and detecting package codes before the worker actually carries the package. The wearable device captures images, recognizes package codes, and prepares attention information in advance, so that when the worker is about to carry a package, the relevant information is immediately displayed with precise timing.
2Reliability
If the system continuously monitors the visual field to detect package codes, then delivery accuracy improves, but the device complexity and processing load increase
Solution Approach 1:
The system extracts only the essential elements needed for delivery support: package code recognition and hand detection. By focusing on these specific features rather than comprehensive scene understanding, the system achieves high delivery accuracy while keeping the image recognition processing relatively simple and manageable.
Solution Approach 2:
The wearable device performs self-service by autonomously capturing images, recognizing package codes, detecting hand positions, and determining whether the worker is about to carry a package without requiring external system intervention. This self-contained approach improves reliability while avoiding the complexity of centralized processing.
3Reliability
If alert information is presented at the moment before package carrying, then delivery errors are reduced, but the timing control complexity increases
Solution Approach 1:
The system performs preliminary detection of package codes and hand positions, then determines the timing of package carrying based on the positional relationship between these elements. By preparing the timing determination in advance through simple geometric relationships rather than complex temporal control, the system reduces delivery errors while maintaining relatively simple control logic.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Reduces delivery errors and improves efficiency by ensuring alert information is timely, guiding workers on package handling and destination verification.
Implementation Method 1
a camera 31, which photographs a visual field of the user
Implementation Method 2
The controller 32 acquires an image captured by the camera 31, recognizes a package as a work target of the user and a hand of the user from the acquired image by image recognition processing
Data Source
AI summary
The camera photographs a visual field of the user. The controller acquires an image captured by the camera, recognizes, through image recognition processing, a package that is a work target of the user and a hand of the user from the acquired image, determines whether or not the user is in a state of being about to carry a package based on a positional relationship between the recognized package and the recognized hand, and recognizes, through image recognition processing, a package ID from the acquired image in a case where it is determined that the user is in a state of being about to carry the package. The communication part receives delivery information regarding the package corresponding to the package ID from a delivery management server. The controller generates, based on the delivery information, alert information to be presented to the user, and outputs the generated alert information.
