3D Object Scanning Interface with Directional Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing object detection techniques require users to manually scan objects from multiple directions, which can be burdensome and difficult, especially when using 2D interfaces, and often fail to guide users in distinguishing the object from its surroundings effectively.
Innovation Solution
A user interface with visual or audible feedback, utilizing sensors like IMUs and VIO, indicates the camera direction relative to the object, facilitating the capture of images from necessary angles and automatically generating a 3D model for object detection by modifying indicators based on the device's orientation and user input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users manually scan objects from multiple directions without guidance, then the scanning process can be completed, but the user burden increases and the operation becomes difficult
Solution Approach 1:
The system provides real-time visual feedback through a circular indicator that shows the current camera direction relative to the object and updates to indicate which directions have been captured. This feedback mechanism guides users through the scanning process without requiring complex manual operations, resolving the contradiction between ease of operation and interface complexity.
Solution Approach 2:
The system pre-establishes the scanning workflow by displaying an indicator that shows the required scanning directions before the user begins. The indicator proactively guides the user through the scanning process, eliminating the need for complex manual guidance and reducing user burden.
2Measurement precision
If users manually position 3D bounding boxes to distinguish object from surroundings, then accurate 3D modeling can be achieved, but the operation becomes difficult especially for users with 2D display interfaces
Solution Approach 1:
The system replaces the mechanical/manual process of positioning 3D bounding boxes with an automated directional indicator system. The circular indicator automatically reflects the camera's current direction relative to the object, eliminating the need for users to manually position bounding boxes on 2D displays while maintaining accurate object identification.
Solution Approach 2:
The circular indicator acts as an intermediary between the camera's physical orientation and the user's understanding of the scanning state. It translates the complex task of manual bounding box positioning into a simple visual feedback mechanism that guides users through the scanning process.
3Manufacturing precision
If the system provides detailed guidance for scanning, then the scanning quality improves, but the interface complexity increases
Solution Approach 1:
The scanning guidance is segmented into discrete directional indicators around the circular indicator, representing different scanning directions. This segmentation provides detailed guidance on scan quality requirements while maintaining a simple, intuitive interface that does not overwhelm the user with complex instructions.

AI summary
Various implementations disclosed herein include devices, systems, and methods that facilitate the creation of a 3D model for object detection based on a scan of the object. Some implementations provide a user interface that a user interacts with to facilitate a scan of an object to create 3D model of the object for later object detection. The user interface may include an indicator that provides visual or audible feedback to the user indicating the direction that the capturing device is facing relative to the object being scanned. The direction of the capture device may be identified using sensors on the device (e.g., inertial measurement unit (IMU), gyroscope, etc.) or other techniques (e.g., visual inertial odometry (VIO)) and based on the user positioning the device so that the object is in view.
