Surround View Crosswalk Departure Control for Pedestrian Detection

Solution Overview

Problem

Existing vehicle cameras have narrow angles of view, making it difficult to detect pedestrians and traffic lights at crosswalks, leading to unauthorized vehicle departures and potential accidents.

Innovation Solution

A surround view camera system with multiple cameras capturing objects from all directions, a recognition part for identifying crosswalks and traffic lights, and a controller to manage vehicle braking and speed based on light colors and pedestrian presence.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Length of moving object

If a front camera with narrow angle of view is used to photograph objects at long distance, then the camera can capture distant objects, but it becomes difficult to detect pedestrians approaching from outside the vehicle and recognize traffic lights

Engineering Contradiction:
Core Design Contradiction:
Length of moving objectVSMeasurement precision

Solution Approach 1:

The patent divides the detection task into multiple segments by using multiple cameras positioned at different locations (front, rear, left, right) with different field of view angles. Each camera captures a specific sector, and the combination provides comprehensive coverage for detecting both distant objects and nearby pedestrians and traffic lights.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent transitions from a single-camera narrow-angle view to a multi-camera surround view system that captures images from multiple dimensions and angles. This dimensional expansion allows simultaneous detection of distant objects and nearby crosswalk elements that were previously invisible from a single viewpoint.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Device complexity

If a single front camera is used for detection, then the system structure is simple, but the system cannot properly detect pedestrians and traffic lights leading to unauthorized vehicle departures

Engineering Contradiction:
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The patent merges multiple camera systems into a unified surround view detection system. By combining the detection capabilities of front, rear, left, and right cameras, the system achieves reliable detection of pedestrians and traffic lights while maintaining a integrated control structure that processes all inputs centrally.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The surround view camera system serves multiple functions: it detects distant objects for collision avoidance, detects nearby pedestrians at crosswalks, recognizes traffic lights, and provides comprehensive situational awareness. This multi-functionality replaces what would otherwise require multiple separate detection systems.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

The present disclosure relates to a system for controlling proper departure of a vehicle on a crosswalk using a parking assistance system, and provides a system for controlling proper departure of a vehicle on a crosswalk, the system comprising: a surround view camera used for parking assistance by photographing objects from all directions of the vehicle; a recognition part for recognizing a crosswalk, a color of a traffic light and a pedestrian from an image captured by the surround view camera; and a controller configured to brake the host vehicle when the crosswalk is recognized and the color of the traffic light is recognized as red, and then determine whether to release braking of the vehicle according to the color of the traffic light and whether the pedestrian is recognized.
