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 20240127605 titled 'DEVICE, METHOD, AND STORAGE MEDIUM FOR DETECTING DECELERATION OF PRECEDING VEHICLE

Simplified Explanation

The apparatus of the present disclosure uses a monocular camera to detect a preceding vehicle and white dashed lines on the road, while also acquiring speed information of the host vehicle. It then analyzes the number of white dashed lines between the preceding vehicle and a fixed reference position in the camera image to detect the deceleration of the preceding vehicle based on the time-series transition of the number of lines and the host vehicle's speed information.

• Detection of preceding vehicle and white dashed lines on the road
• Acquisition of speed information of the host vehicle
• Analysis of the number of white dashed lines to detect deceleration of the preceding vehicle

Potential Applications

This technology can be applied in:

• Advanced driver assistance systems
• Autonomous vehicles
• Traffic flow optimization

Problems Solved

This technology helps in:

• Improving road safety by detecting deceleration of preceding vehicles
• Enhancing driver assistance systems for better decision-making
• Optimizing traffic flow by predicting potential slowdowns

Benefits

The benefits of this technology include:

• Increased road safety
• Enhanced driving experience
• Improved traffic management and efficiency

Potential Commercial Applications

This technology can be commercially applied in:

• Automotive industry for advanced driver assistance systems
• Transportation and logistics companies for fleet management
• Traffic management authorities for optimizing traffic flow

Possible Prior Art

One possible prior art for this technology could be the use of radar or lidar sensors in vehicles to detect the speed and distance of surrounding vehicles. Another could be the use of computer vision algorithms to analyze road markings and detect lane boundaries.

How does this technology handle adverse weather conditions that may affect camera visibility?

The abstract does not mention how the apparatus deals with situations where the camera's visibility is compromised due to adverse weather conditions such as heavy rain or fog.

What is the accuracy rate of the apparatus in detecting deceleration of preceding vehicles based on the number of white dashed lines?

The abstract does not provide information on the accuracy rate of the apparatus in detecting deceleration of preceding vehicles, which could be crucial for assessing the reliability 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.
