Person Counting Area Setup via Gate Position Parameters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing person counting systems require skilled operators to set up person counting areas, making it difficult for unskilled individuals to easily configure and manage these areas, especially in large-scale stores with multiple cameras, leading to inefficiencies in setting and maintaining accurate counting systems.
Innovation Solution
A method and system that includes a camera device and server device connection, allowing for the display of captured images, generation of person counting areas, and superimposition of these areas onto the images based on input parameters, enabling easy setup and transmission of settings to the camera device for accurate person counting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual setting of person counting area is performed by unskilled operators, then ease of operation is improved, but setting accuracy and reliability deteriorate
Solution Approach 1:
The system performs preliminary actions by automatically generating candidate person counting areas based on gate position information before the operator needs to set the final area. The server device creates multiple candidate areas in advance, which are then displayed to the operator for selection, eliminating the need for operators to manually define complex geometric areas from scratch.
Solution Approach 2:
The server device acts as an intermediary between the camera device and the operator. It receives gate position information, generates candidate person counting areas, and presents these candidates to the operator for selection. This intermediary processing ensures that even unskilled operators can achieve accurate settings by choosing from pre-computed candidates rather than manually defining areas.
2Ease of operation
If automatic generation of person counting areas is implemented, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The system segments the person counting area setting task into distinct functional modules: gate position detection, candidate area generation, candidate display, and final selection. By dividing the complex task into separate manageable steps handled by different components (camera device, server device, display unit), the overall system complexity is distributed and made more controllable while maintaining ease of operation.
Solution Approach 2:
The server device performs multiple functions: it manages communication between camera devices, generates candidate person counting areas, displays candidates to operators, and receives final selections. This multi-functionality consolidates complexity into a single centralized component rather than distributing it across multiple devices, simplifying the overall system architecture while enabling automatic area generation.
3Area of stationary object
If multiple cameras are installed in large-scale stores, then surveillance coverage is improved, but time required for setting person counting areas increases
Solution Approach 1:
The system enables self-service by allowing the server device to automatically generate candidate person counting areas for multiple cameras without requiring skilled operators to manually configure each camera. The automated generation process handles the complex geometric calculations and area definitions, reducing setting time while maintaining accuracy across all cameras in large-scale stores.
Solution Approach 2:
The system changes parameters by using gate position information as input to generate multiple candidate person counting areas with different geometric configurations. By varying parameters such as area shape, size, and position based on the gate location, the system can quickly adapt settings for multiple cameras covering different areas of large-scale stores without manual reconfiguration for each camera.

AI summary
A person counting area setting method includes displaying a captured image of an imaging area captured by a camera device on a display, generating an image of a person counting area for counting the number of one or more persons who pass through a gate pictured on the captured image displayed on the display and displaying the generated image on the display such that the generated image is superimposed on the captured image based on a first parameter indicating a position of the gate in a case where the first parameter is input, and transmitting the information regarding the person counting area to the camera device and setting the transmitted information for the camera device.
