Further technical scheme of the present invention is described in detail with specific embodiment below.
Embodiment one:
First reference point setting module 1 needs to determine plane parallel with floor in a room, can be floor or ceiling in reality, because these two planes are preferably determined.Sweep and clap room half cycle, reference point determination module 2 locks ceiling three turnings, the both sides of door 6 and two of ceiling vertical points.Givenly determine the left side D point of positive opposite house 6 as after a reference plane 7 of Fig. 4, then by camera locking A, B, C, D, E, F point of hand-held intelligent equipment.Given room type, according to the length of the relative position of these reference points and the width d calculated room of door 6 and wide, the equipment of automatic generation room floor plan of the present invention can generate the room floor plan of the full-size(d) of vector format.Hand-held intelligent equipment preferably possesses the hardware device such as gyroscope or three-dimensional acceleration sensor to support angle measuring function.
See the computer program process flow diagram that Fig. 3, Fig. 3 are one embodiment of the invention.
After reference point setting module 1 sets reference point O, reference point determination module 2 locks reference point, with electronic compass record current device towards (such as eastern inclined 30 degree, inclined 45 degree of south etc.), first the camera of handheld device is utilized to lock first corner (A point), press acknowledgement key after locking, locking process completely manually also can use image recognition technology secondary locking;
Calculate locking last reference point time equipment towards with current towards angular deviation, judge whether next reference point, if have, then equipment turns to next reference point, and locks B successively with the camera of handheld device, C, D, E, F point, utilize 3D acceleration sensor or the gyroscope of handheld device, Angle Measurement Module 3 takes measurement of an angle θ 1 ~ θ 5 automatically;
If do not have next reference point, then determine invariant (door 6 is wide), length and width calculation module 4 are according to the length of triangle formula calculated room, wide:
DF can be calculated successively, the distance between CD, BC, AB.Because the door 6 of chummery is not wide is standard, if user selects room type, such as parlor, bedroom, dining room etc., system will confirm the distance between DE.If this distance is d.Specific formula for calculation is as follows:
