Importing a Floor Background Image

In Fenix+ 3 Classic, you can import images with floor topologies into scenarios. You can import such images for any floor in the building. Using images with floor topologies makes it easy to create topology of the building.

An image with a floor topology can only be imported to the selected floor.

To import an image with a floor topology, do the following:

1. Right-click the name of a desired floor in the scenario browser and select Import.

{width=50%}

2. In the opened dialog box, select the image you want to import and click OK.

The program supports importing images in the following formats: bmp, jpg, jpeg, png.

As a result, the window shown in the figure below will open.

{width=80%}

On the left side of the window, there is a preview area where the imported image is displayed. On the right side of the window, there are control elements which you can use to prepare the image for importing into the project. You can perform the following actions with the image:

• Scale image

• Scale and rotate image at a specific angle

• Eliminate distortion

• Set a reference point for automatic alignment of imported images.

Using the additional Move, Zoom and See all, tools you can view any part of the image.

3. To finish the import, click Import.

As a result, the image will be displayed on the selected floor.

Below is the description of the actions that you can do to prepare an image for importing into the project.

Scaling image

Before importing the image into the preject, it is recommended to scale the image. The program allows to scale the image, if you know the size of at least one object in this image.

To scale the image, follow these steps:

• In the right part of the Import Image window, select the Set scale size option.

{width=45%}

• Use the mouse to draw a line equal to the length of the object of a known size in the image. This line will be displayed as a red line with an arrow.

{width=70%}

For the purpose of accuracy, it is recommended to draw a line with the length equal to the largest dimension of the known object in the image (for example, the length of the wall).

• In the Direction 1 section, specify the known size and the measurement unit.

{width=40%}

• To save changes, click Apply.

The program will use the specified size to scale the scale.

To finish the import, click Import. The image will be displayed on the selected floor.

Scaling and rotating the image by a given angle

In some cases, you may not only need to scale the image, but also to rotate the image by a certain angle clockwise or counterclockwise. To do this, follow these steps:

• In the right part of the Import Image window, select the Set scale size and rotate option.

{width=40%}

• Use the mouse to draw a line of a known size on the image. The line will be displayed as a red line with an arrow.

{width=60%}

For the purpose of accuracy, it is recommended to draw a line with the length equal to the largest dimension of the known object in the image (for example, the length of the wall).

• In the Direction 1 section, specify the known size and the measurement unit.

• In the Angle field, specify the rotation angle. The rotation angle is the angle between the drawn line and the unit vector (1;0) drawn from the starting point of this line.

{width=40%}

To rotate the image clockwise, specify a negative value for the rotation angle.

• To save changes, click Apply.

The program will set the scale size and rotate the image by the specified angle.

{width=80%}

If you need to change the angle rotation, specify a new value and click Apply button.

To finish the import, click Import. The image will be displayed on the selected floor.

Correcting Skew

If the image was obtained using a camera, it may be necessary to correct the existing “skew”.

Fenix+ 3 Classic allows to correct only small image “distortions”.

To eliminate image distortion, do the following:

• In the right part of the Import Image window, select the Correct skew option.

{width=40%}

• Indicate the first segment of known size on the image. The indicated segment will be displayed as a red arrow. In the parameter group Direction 1, specify the actual size of the segment, unit of measurement and set the angle of rotation.

• Indicate the second segment of known size on the image. The indicated line will be displayed as a green arrow. In the parameter group Direction 2, specify the actual size of the segment, unit of measurement and set the angle of rotation.

{width=80%}

• Click Apply.

{width=80%}

As a result, image distortion will be eliminated.

To finish the import, click Import. The image will be displayed on the selected floor.

Indication of the reference point

When you import images with floor topologies for different floors, you can specify a reference point with the same coordinates (X, Y) on each of these images. After the import is complete, the program will combine all imported images at the specified point automatically. This function eliminates the need for subsequent combination of imported images in the scene editor manually.

This function can be used when you import several images for one and multiple floors in a building.

To specify a reference point, do the following:

• Press the button.
• Specify a reference point on the image.

The reference point is recommended to be indicated in a place that can be uniquely identified on all imported images that need to be combined.

• In the Reference point coordinates section, specify coordinates of the reference point.

{width=40%}

• Specify a segment of a known size on the image. The indicated line will be displayed as a red arrow.

• In the Direction 1 section, specify the actual size of the segment and the measurement unit.

{width=40%}

• To save changes, click Apply.

Click Import. The image will be displayed on the selected floor.

Repeat this procedure for the other images with floor topologies, you want to import into the project. As a result, the imported images will be displayed on the corresponding floors. Images will be aligned at the specified point.

Importing Floor Topology From a Drawing
