Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stay condition analyzing systems face issues with mismatch between background images and heat map images, leading to an uncomfortable user experience due to differences in the actual and visualized stay states of individuals within a target area.
Innovation Solution
A stay condition analyzing apparatus that acquires stay information and generates a heat map image, with a background image generator performing image processing to reduce the discriminability of moving objects in captured images, ensuring a natural display by matching the background and heat map images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a captured image is used as a background image, then it is easy to generate the background image, but the background image and heat map image do not match, causing user discomfort
Solution Approach 1:
The patent applies preliminary action by generating a background image from captured images before superimposing the heat map image. The background image is created by processing captured images to remove or blur moving objects, ensuring that the background represents the static environment. This preliminary preparation of the background image resolves the mismatch issue between the background and heat map images, while maintaining ease of generation.
2Reliability
If a plan view of the target area is used as a background image, then the background image and heat map image match well, but it requires multiple cameras and complex image processing
Solution Approach 1:
The patent applies universality by enabling a single camera to perform multiple functions: capturing images for both heat map generation and background image creation. The system processes captured images to extract both stay information (for heat maps) and background information (by removing moving objects). This multi-functional approach achieves plan-view-quality matching without requiring multiple cameras or complex multi-camera coordination systems.
3Measurement precision
If captured images at multiple time points are processed, then accurate stay information is obtained, but the background image becomes inconsistent with the heat map image
Solution Approach 1:
The patent applies extraction by separating the background information from the captured images through image processing that removes or blurs moving objects. By extracting only the static background elements and excluding dynamic objects from the background image, the system maintains consistency between the background image and heat map image even when processing multiple time-point images for accurate stay information calculation.

AI summary
Provided is a stay condition analyzing apparatus including a stay information acquirer which acquires stay information for each predetermined measurement period of time on the basis of positional information of a moving object which is acquired from a captured image of a target area, a heat map image generator which generates a heat map image obtained by visualizing the stay information, a background image generator which generates a background image from the captured image, and a display image generator which generates a display image by superimposing the heat map image on the background image. The background image generator generates the background image by performing image processing for reducing discriminability of the moving object appearing in the captured image on the captured image.
