Floor plan space detection

摘要

Methods, machine-readable media, and devices for floor plan space detection are described herein. For example, one or more embodiments include receiving an image of a floor plan, enhancing the image of the floor plan through processing, detecting a location of a door associated with a space in the image of the floor plan through a histogram of gradient of pattern feature, setting a seed in the space based on the location of the door associated with the space, spreading the seed in the space until the seed reaches a boundary of the space, and associating the seed that has been spread with the space.

1. A method for floor plan space detection, comprising:
receiving an image of a floor plan; enhancing the image of the floor plan through processing; detecting a location of a door associated with a space in the image of the floor plan through a histogram of gradient of pattern feature, wherein the space is set to a first color and the door associated with the space and a boundary of the space in the image of the floor plan is set to a second color different than the first color; setting a seed of the second color in the space based on the location of the door associated with the space; determining a color of a pixel within a radius of the seed; comparing the color of the pixel within the radius of the seed to the color of the seed; adding the pixel within the radius of the seed to the seed when the color of the pixel within the radius of the seed has the same color of the seed; spreading the seed in the space until the seed reaches a boundary of the space; and associating the seed that has been spread with the space.
