==DEVICE, METHOD, AND STORAGE MEDIUM FOR DETECTING DECELERATION OF PRECEDING VEHICLE - A simplified explanation of the abstract==


This abstract first appeared for US patent application 18359972 titled 'DEVICE, METHOD, AND STORAGE MEDIUM FOR DETECTING DECELERATION OF PRECEDING VEHICLE

==Simplified Explanation==

The apparatus of the present disclosure detects a preceding vehicle and a white dashed line provided at regular intervals along a road from an image captured by a monocular camera. It also acquires speed information of the host vehicle, counts the number of white dashed lines in a section from the vertical position of the preceding vehicle to a lower fixed reference position, and detects the deceleration of the preceding vehicle based on the time-series transition of the number of white dashed lines and the speed information of the host vehicle.

* Detection of preceding vehicle and white dashed lines from camera image
* Acquisition of speed information of host vehicle
* Counting of white dashed lines in a specific section of the road
* Detection of deceleration of preceding vehicle based on line count and speed information

== Potential Applications ==
This technology could be applied in:
* Advanced driver assistance systems
* Autonomous vehicles
* Traffic flow optimization

== Problems Solved ==
This technology helps in:
* Enhancing road safety by detecting deceleration of preceding vehicles
* Improving traffic management by analyzing speed and lane information
* Providing real-time data for better decision-making on the road

== Benefits ==
The benefits of this technology include:
* Increased safety on the road
* Efficient traffic flow
* Enhanced driver assistance features

== Potential Commercial Applications ==
The potential commercial applications of this technology could be in:
* Automotive industry for vehicle safety systems
* Transportation and logistics for fleet management
* Traffic control and management systems

== Possible Prior Art ==
One possible prior art could be the use of radar or lidar sensors in vehicles to detect surrounding objects and vehicles for collision avoidance systems.

=== Unanswered Questions ===

== How does this technology differentiate between different types of road markings, such as solid lines or arrows? ==
The abstract does not specify how the apparatus distinguishes between various types of road markings, which could be crucial for accurate detection and analysis.

== What is the accuracy rate of the deceleration detection based on the number of white dashed lines? ==
The abstract does not mention the accuracy or reliability of the deceleration detection method, which could impact the effectiveness of the technology in real-world scenarios.


==Original Abstract Submitted==

The apparatus of the present disclosure detects a preceding vehicle and a white dashed line provided at regular intervals along a road from an image captured by a monocular camera. In addition, the apparatus of the present disclosure acquires speed information of the host vehicle. Then, the apparatus of the present disclosure counts the number of white dashed lines included in the section from the vertical position of the preceding vehicle to the lower fixed reference position of the vertical position in the camera image, and detects the deceleration of the preceding vehicle based on the time-series transition of the number of white dashed lines and the speed information of the host vehicle.
