POSITION ESTIMATION SYSTEM, POSITION ESTIMATION METHOD, AND PROGRAM - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240112363 titled 'POSITION ESTIMATION SYSTEM, POSITION ESTIMATION METHOD, AND PROGRAM

Simplified Explanation

The abstract describes a position estimation system that can estimate the position of a moving body without the need for installing an object on the body. The system involves generating mask images, performing perspective transformation, and calculating coordinate points to determine the position of the moving body.

• Detection unit generates a first mask image
• Mask area masking the moving body is added to the first mask image
• Perspective transformation unit transforms the first mask image
• Position calculation unit corrects coordinate points and calculates the position of the moving body

Potential Applications

This technology could be used in various industries such as:

• Autonomous vehicles
• Robotics
• Surveillance systems

Problems Solved

This technology solves the following problems:

• Eliminates the need for physical installation on the moving body
• Provides accurate position estimation without direct contact

Benefits

The benefits of this technology include:

• Improved accuracy in position estimation
• Non-intrusive method of tracking moving bodies
• Cost-effective solution for position tracking

Potential Commercial Applications

The potential commercial applications of this technology could be seen in:

• Transportation industry
• Security and surveillance systems
• Sports analytics

Possible Prior Art

One possible prior art could be the use of GPS technology for position tracking, which may not be as accurate in certain environments or require direct contact with the moving body.

How does this technology handle occlusions in the environment?

The abstract does not mention how the system deals with obstacles or occlusions that may obstruct the view of the moving body.

What is the processing time required for position estimation?

The abstract does not provide information on the speed or processing time needed for the system to estimate the position of the moving body.

Original Abstract Submitted

a position estimation system, a position estimation method, and a program that can estimate a position of a moving body without installing an installation object on the moving body are provided. a position estimation system includes a detection unit configured to generate a first mask image, a mask area masking a moving body in an image photographed being added to the first mask image, a perspective transformation unit configured to perform perspective transformation on the first mask image, and a position calculation unit configured to correct a coordinate point of a first circumscribed rectangle set for a mask area in the first mask image using a second coordinate point of the mask area in the second mask image, which is obtained by performing perspective transformation on the first mask, to calculate a third coordinate point.
