Abstract EN
Fall prevention is an important issue particularly for the elderly.
This paper proposes a camera-based line-laser obstacle detection system to prevent falls in the indoor environment.
When obstacles are detected, the system will emit alarm messages to catch the attention of the user.
Because the elderly spend a lot of their time at home, the proposed line-laser obstacle detection system is designed mainly for indoor applications.
Our obstacle detection system casts a laser line, which passes through a horizontal plane and has a specific height to the ground.
A camera, whose optical axis has a specific inclined angle to the plane, will observe the laser pattern to obtain the potential obstacles.
Based on this configuration, the distance between the obstacles and the system can be further determined by a perspective transformation called homography.
After conducting the experiments, critical parameters of the algorithms can be determined, and the detected obstacles can be classified into different levels of danger, causing the system to send different alarm messages.
