Solution Overview

Problem

Existing PTZ camera systems with adjacent fisheye and PTZ cameras have complex configurations and high operational costs due to the need for cumbersome calibration processes.

Innovation Solution

A PTZ camera operating system that generates a hemispherical fisheye image using individual images captured by a PTZ camera, allowing for intuitive surveillance area setting through a user interface (UI) without the need for a separate fisheye camera, using grid or polygon selection methods.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a separate fisheye camera is installed adjacent to the PTZ camera for surveillance area setting, then the surveillance area can be set automatically without calibration, but the system configuration becomes complicated and operational costs increase

Engineering Contradiction:

Improvesurveillance area settingVSAvoidsystem configuration

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent merges the fisheye camera and PTZ camera into a single integrated device. The fisheye lens captures a wide-angle view while the PTZ mechanism provides directional control, eliminating the need for separate cameras and reducing system complexity while maintaining automated surveillance area setting functionality

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The integrated camera system performs multiple functions: the fisheye lens provides wide-area monitoring while the PTZ mechanism enables targeted surveillance and zoom capabilities. This multi-functionality replaces what previously required separate devices, simplifying the overall system configuration

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Ease of operation

Engineering Contradiction:

Improvesurveillance area settingVSAvoidsystem operation costs

Core Design Contradiction:

Ease of operationVSQuantity of substance

Solution Approach 1:

By combining the fisheye camera and PTZ camera into one integrated device, the patent reduces the quantity of equipment needed for system operation. This consolidation directly lowers operational costs by eliminating maintenance, power, and operational expenses associated with a separate fisheye camera

Inventive Principle:

Principle #5Merging (Combining)

3Device complexity

If individual images within motion range are used to generate hemispherical fisheye image, then the system configuration is simplified, but the surveillance area setting requires user interaction

Engineering Contradiction:

Improvesystem configurationVSAvoidsurveillance area setting

Core Design Contradiction:

Device complexityVSEase of operation

Solution Approach 1:

The system performs preliminary actions by automatically capturing individual images throughout the PTZ motion range and pre-processing them to generate the hemispherical fisheye image. This preliminary preparation creates a ready-to-use visual interface that guides users through surveillance area setting, making the process intuitive despite requiring user interaction
