Samsung patents method to match LiDAR scans with indoor floor plans
Samsung has filed a patent for a method that aligns 3D map data created by a LiDAR sensor with a 2D floor plan image of an indoor space. The system uses an AI model to break the floor plan into sections and compares them with the sensor data to ensure the digital map matches the physical layout.
In the filing’s own words
A method of aligning map data with a floor plan image includes: obtaining a first floor plan image corresponding to an indoor space; segmenting the indoor space into a plurality of areas by inputting the first floor plan image into a first artificial intelligence model; obtaining a second floor plan image corresponding to the indoor space and excluding a predefined area from among the plurality of areas of the first floor plan image; obtaining first map data and trajectory information from an electronic device including a LiDAR sensor for scanning the indoor space; based on the trajectory information, obtaining second map data corresponding to an area in which the LiDAR sensor has traveled, from among the first map data; and aligning the first map data with the first floor plan image, based on the second floor plan image and the second map data.
What exactly they claim (claim 1)
1. A method of aligning map data with a floor plan image, the method comprising: obtaining a first floor plan image corresponding to an indoor space; segmenting the indoor space into a plurality of areas by inputting the first floor plan image into a first artificial intelligence model; obtaining a second floor plan image corresponding to the indoor space and excluding a predefined area from among the plurality of areas of the first floor plan image; obtaining first map data and trajectory information from an electronic device including a LIDAR sensor for scanning the indoor space; based on the trajectory information, obtaining second map data corresponding to an area in which the LiDAR sensor has traveled, from among the first map data; and aligning the first map data with the first floor plan image, based on the second floor plan image and the second map data.
