1 is a block diagram showing a portable terminal according to an embodiment of the present invention, and FIG. 2 is a block diagram showing a configuration of a portable terminal according to an embodiment of the present invention in more detail.

The portable terminal 100 described in the present specification includes a mobile phone, a smart phone, a computer, a laptop computer, a digital broadcasting terminal, a personal digital assistant (PDA), a portable multimedia device (PMP) operated according to a user input. Player), a navigation device, a virtual reality device, and other electronic devices may be exemplified.

In addition, a program or application for executing methods according to an embodiment of the present invention may be installed and operated in the portable terminal 100.

Accordingly, the portable terminal 100 according to the embodiment of the present invention may provide an interface for generating indoor structure information, and the indoor structure information generated according to the embodiment of the present invention is stored in the portable terminal 100, or It can be uploaded to a separate server (not shown) and managed according to user information.

Here, the indoor structure information may include 2D building plan information, and may include structure information that may be used for indoor interior simulation by matching 3D modeling information. In addition, the indoor structure information may include one or more wall surfaces and connection information of each wall surface, and may form one or more closed spaces.

In order to facilitate the generation of such indoor structure information, the portable terminal 100 may include a distance measurement sensor and an angle measurement sensor, and from measurement information corresponding to the first wall surface 200 pointed indoors according to a user input. The first coordinate point 201 and the second coordinate point 202 may be calculated, and structural information of the first wall surface 200 based on the first coordinate point 201 and the second coordinate point 202 may be determined. . The structure information of the first wall surface 200 may be calculated as an infinite linear function connecting the first coordinate point 201 and the second coordinate point 202, and the linear function is each of the wall surfaces 200 and 210 Each can be determined individually.

Accordingly, the portable terminal 100 extends the linear functions corresponding to the respective wall surfaces 200 and 210, and can identify the intersection 203 between the linear functions, and the first corresponding to the intersection 203 The connection between the wall surface and the second wall surface can be processed, and the corner position and corner angle between intersection points can be predicted.

In particular, corner positions and corner angles are very important factors in calculating the floor plan of an indoor building, but there is a problem that it is difficult to accurately measure with the existing whole scanning method. As it is calculated as the linearly calculated intersection 203 between the extension lines of the first wall surface 200 and the second wall surface 210, it is possible to calculate very accurate indoor structure information.

In addition, according to an embodiment of the present invention, the indoor structure information can be completed by allowing the user to repeatedly perform the measurement and connection process of each wall surface in the first direction until the closed space is formed.

For example, some prior art techniques in the past include techniques used to calculate indoor structure information by measuring the corners of a space, but there is a problem in that it is almost impossible to accurately measure with only such measurements.

On the contrary, in the portable terminal 100 according to an embodiment of the present invention, an accurate wall structure can be calculated simply by pointing two coordinate points on the wall, and the wall surface can be mapped with a linear function passing through the two measured points. As can be seen, by repeating this for all walls of the indoor space, the wall and potential wall extension lines are calculated, and the corner position and angle information according to the connection can be accurately calculated.

However, for this purpose, the user of the portable terminal 100 needs to continuously measure the wall surface in a specific first direction (for example, clockwise or counterclockwise). Therefore, after measuring the first wall surface, The second wall surface must be adjacent to the first wall, and there is a need to maintain the first direction in the entire indoor structure information generation process.

In addition, it is preferable that the portable terminal 100 moves at a certain speed or less during measurement. This is to increase the accuracy in measuring the location and angle of the portable terminal 100.

In addition, the first coordinate point and the second coordinate point are preferably separated by a predetermined distance or more, and the height is preferably adjacent within a predetermined height. This is because it is easy to calculate an accurate linear function.

The indoor simulation is a three-dimensional space similar to reality on a virtual space displayed on the display of the portable terminal 100. It may include a function of visualizing and disposing a corresponding 3D object on the indoor simulation graphic based on the indoor structure information freely. Accordingly, the indoor simulation may be preferably used for a floor plan (FLOOR PLAN) that simulates furniture to be placed in a room, and an application providing the indoor simulation may include a floor plan application.

3 is a more detailed block diagram of a spatial information generator according to an embodiment of the present invention.

Referring to FIG. 3, the spatial information generation unit 130 according to an embodiment of the present invention includes a measurement point coordinate calculation unit 131, a wall information calculation unit 133, a corner calculation unit 135, and a spatial information determination unit 137. And a correction unit 139.

The measuring point coordinate calculating unit 131 calculates the coordinates of the measuring point on the wall based on distance information and three-dimensional angle information sensed by the distance measuring unit 121 and the angle measuring unit 122, and a first corresponding to the first wall surface. Coordinate point information and second coordinate point information may be output.

More specifically, the measuring point coordinate calculating unit 131 may calculate the coordinates of the measuring point on the wall on the assumption that each wall surface is formed vertically from the ground and is formed in a straight line shape instead of a curved surface.

For example, the measuring point coordinate calculating unit 131 uses the current position of the user measured from the position measuring unit 123 as a reference point, and the wall surface in the direction pointed from the current position according to the distance information obtained from the distance measuring unit 121 You can measure the pointing distance information to.

At this time, the measuring point coordinate calculator 131 may cosine the pointing distance information and the pitch angle information among the current three-dimensional angle information to calculate the parallel distance information of the line segment parallel to the ground, which is the user's current It can be determined by the 2D distance information from the location to the wall surface. That is, the parallel distance information from the user to the wall surface = pointed distance information x COS (pitch angle) can be calculated.

In addition, the measuring point coordinate calculating unit 131 may calculate parallel distance information and three-dimensional angle information important yaw angle information to calculate coordinate point information of a wall corresponding to the current position. If the parallel distance information is l, the pitch angle is θ, the yaw angle information is Φ, and the current position is (x0, y0), the current coordinate point information (x , y) can be calculated.

In addition, when the first coordinate points (x1, y1) of the first wall surface are measured, the measuring point coordinate calculating unit 131 may additionally measure the second coordinate points (x2, y2) of the first wall surface. Here, there may be at least two coordinate points corresponding to each wall surface, and two coordinate points for the sequential wall surfaces in the first direction may be calculated respectively according to the provision of the interface.

In addition, when two or more coordinate points of each wall surface are calculated, the wall surface information calculating unit 133 calculates wall surface structure information by processing a linear function operation corresponding to each coordinate point.

The wall information calculating unit 133 may determine each wall structure information in the form of a linear function equation (y = ax + b) connecting two coordinate points. Each wall surface structure information may include a measured wall surface portion and a predicted wall surface portion extending infinitely from the wall surface portion.

Further, the corner calculator 135 may calculate corner information connecting each wall surface based on an intersection point calculation of each wall structure information, and the corner information may include corner position information and corner angle information.

More specifically, the corner calculation unit 135 calculates the slope s of each of the first and second wall surfaces in order to calculate corner information between the first and second wall surfaces, and y based on one point of each wall surface. Intercept values can be calculated. (y_0-s*x_0 = b)

Here, if the first linear function of the first wall is ax + b = y and the second linear function of the second wall is cx + d = y, then x at the intersection point where x and y of the two linear functions coincide = can be calculated as (db)/(ac). Here, a may be a slope of the first wall, c may be a slope of the second wall, b may be a y-intercept of the first wall, and d may be a y-intercept of the second wall.

In addition, the corner calculator 135 may calculate the y value by applying the calculated x coordinate value to the first wall surface or the second wall surface linear function. Accordingly, the obtained corner position information (x, y) may be calculated, and corner angle information by an operation between slopes of the first linear function and the second linear function may be calculated corresponding to the corner position information.

The spatial information determiner 137 may determine spatial information connecting each corner and walls based on the calculated wall structure information and corner information. For example, the spatial information determining unit 137 may determine the spatial information and give a label such as Room 1, when a closed space is formed according to the connection of each corner and the wall.

Meanwhile, the correction unit 139 may perform a correction process in consideration of that the wall surface structure information is typically a right angle (90 degrees) in response to the corner angle information of the corner information. For example, when the corner angle information is within a certain angle corresponding to 90 degrees, the correction unit 139 may perform a correction process of correcting the corner angle information by 90 degrees. Accordingly, it is possible to accurately structure the overall building floor plan.
