Solution Overview

Problem

Conventional access control methods in places like government buildings and office complexes face challenges in accurately identifying individuals due to issues with card replacement and high false alarm rates from face recognition systems, especially with occlusions and varying angles.

Innovation Solution

An image processing method and apparatus that captures images from multiple camera modules, compares them to a target library, and performs joint authentication when initial authentication fails, improving accuracy and reducing false alarms.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If conventional face recognition is used for access control, then authentication speed is improved, but measurement precision deteriorates due to face occlusion, side face, and bowed head causing high false alarm rates

Engineering Contradiction:
Improveauthentication speedVSAvoididentity recognition accuracy
Core Design Contradiction:
SpeedVSMeasurement precision

Solution Approach 1:

The patent transitions from single-camera 2D face recognition to multi-camera 3D spatial positioning. By capturing images from multiple camera modules at different positions and performing three-dimensional positioning of the object based on these images, the system resolves the contradiction by adding a spatial dimension that enables accurate identification regardless of face orientation or occlusion in any single view

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Device complexity

If single camera module is used for authentication, then device complexity is reduced, but measurement precision deteriorates due to inability to capture multiple angles and reduce false alarms

Engineering Contradiction:
Improvesystem structureVSAvoididentity recognition accuracy
Core Design Contradiction:
Device complexityVSMeasurement precision

Solution Approach 1:

The patent merges multiple camera modules into a coordinated authentication system. The first camera module performs initial authentication, and upon failure, the system activates additional second camera modules for joint authentication. This combining approach improves measurement precision by capturing the object from multiple angles while maintaining manageable device complexity through selective activation

Inventive Principle:
Principle #5Merging (Combining)

AI summary

An image processing method and apparatus, and a storage medium are provided. The method includes: obtaining a first image and a second image of a to-be-authenticated object, where the first image is captured by a first camera module, and the second image is captured by at least one second camera module; comparing the first image with image data in a target library for identity authentication, to obtain a first authentication result; and in response to that the first authentication result is authentication failure, performing joint authentication on the first image and the second image, and determining the identity of the to-be-authenticated object according to a second authentication result of the joint authentication.
