Abstract

We propose and demonstrate methods for detection and manipulation of laser projection pattern to apply to effective evacuation guidance after a disaster. A lock-in detection of laser projection pattern in which a reference signal is obtained from a raster scan frequency of the laser projection, is found to be effective to highlight the pattern captured by using an image sensor. Combination of the highlighted pattern and RGB strength distribution allows us to extract an area that can be used for the laser projection with high-visibility. Our methods are expected to be used for effective evacuation guidance.
