The Fenix+ 3 application allows you to import a floor background image (underlay), which contains the floor plan, into your project. The underlay can be imported for any floor of the building. Using underlays makes it easier to draw the topology of a building.
You can import a background image only to the previously selected floor of the building.
To import a background image do the following:
- Right-click the name of a desired floor in the scenario browser and select Import.
{width=50%}
- In the dialog box that opens, select the image to import and click the OK button.
The application supports the import the following image formats: bmp, jpg, jpeg, png.
An import window opens as shown in the image below.
{width=80%}
On the left side of the window is the preview area, where the imported image is displayed. On the right side of the window are control elements that you can use to configure the image for import into the project. You can perform the following actions with the importing image:
- Setting the scale of the image;
- Setting the scale and rotating the image by a specified angle;
- Correcting a skew;
- Setting a reference point for automatic alignment of images.
For instructions on configuring the image for import into the project, read below.
Using the additional Move, Zoom and View all tools you can scale up any image area for viewing.
- To finish the import, click Import.
As a result, the image is added as an underlay on the selected floor.
Below is the description of the actions that you can take to configure the image for import into the project.
Scale image
Before importing the image into the project, it is recommended to set the scale of the imported image. The application allows to set the image scale if the dimensions of at least one object in the image are known.
To scale the imported image do the following:
- In the right part of the Import Image window, select the Set scale option.
{width=45%}
- Using the mouse, indicate a segment of known size on the image. The specified segment is displayed as a red arrow.
{width=70%}
To increase accuracy, you must indicate the longest segment the length of which is known.
- In the Direction 1 parameter group specify the actual size and the measurement unit.
{width=40%}
- To save changes, click Apply.
Based on the specified segment size, the application sets the image scale.
To finish the import, click Import. The image is added as a background to the selected floor.
Setting the scale and rotating the imported image by a specified angle
In some cases, before importing, it can be necessary not only to set the scale, but also to rotate the imported 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 and rotate option.
{width=40%}
- Using the mouse, indicate a segment of known size on the image. The specified segment is displayed as a red arrow.
{width=60%}
To increase accuracy, you must indicate the longest segment the length of which is known.
- In the Direction 1 parameter group, specify the actual 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 application sets the scale and rotates the image by the specified angle.
{width=80%}
If you need to change the rotation angle, specify a new angle value and click Apply button.
To finish the import, click Import. The image is added on the selected floor as an underlay.
Correcting Skew
If the imported image was obtained using a camera, it may be necessary to correct the existing perspective skew.
Fenix+ 3 application allows you to correct only slight image perspective skews.
To eliminate image skew, 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 is displayed as a red arrow. In the Direction 1 parameter group, specify the actual size of the segment, measurement unit, and set the rotation angle.
- Indicate the second segment of known size on the image. The indicated line is displayed as a green arrow. In the Direction 2 parameter group, specify the actual size of the segment, measurement unit, and set the rotation angle.
{width=80%}
- Click Apply.
{width=80%}
As a result, image skew is eliminated.
To finish the import, click Import. The image is added to the selected floor.
Specifying a reference point
When importing images (underlays) for different floors of a building, you can specify a reference point with the same coordinates (X, Y) on each imported image. After the import is completed, the application automatically alignes all imported images at the specified point. This feature eliminates the need for subsequent manual alignment of imported images in the scene editor.
You can use this function when importing several images either for one or multiple floors of a building.
To specify a reference point do the following:
- Press the
button. - Specify a reference point on the image.
It is recommended to specify the reference point in a place that can be clearly identified on all imported images that must be aligned.
- In the Reference point coordinates section, specify the desired coordinates of the reference point.
{width=40%}
- Specify a segment of a known size on the image. The indicated line is displayed as a red arrow.
- In the right part of the window, in the Direction 1 parameter group, specify the actual size of the segment and the measurement unit.
{width=40%}
- To save changes, click Apply.
Click Import. The image is added on the selected floor.
Repeat the steps above for the remaining images you import. As a result, all images are imported into the project as underlays for the corresponding floors. All underlays are aligned at the specified point.
