Post-processing Using Spatial Relationships for Button Recognition

With rapid technological advances, the autonomous mobile robot market has grown remarkably in recent years. However, these autonomous mobile robots and their services still need to improve in the real world. Among various services, we focused on services that drive in multiple spaces in a multi-story building using an elevator. To operate the elevator, the mobile robot must be able to operate by pressing the elevator button. In particular, in this paper, we proposed a post-processing method using spatial relationships applicable to various elevator button recognition. We define the relationship between buttons, configure them to apply to the results of previous button recognition studies, and show performance improvement through button recognition post-processing in an actual situation.
