 Positions of active camera

Positions are copies of cameras that can be saved and loaded to the parent camera. Position includes almost all camera parameters, not just its position. The number of positions of each camera is not limited.


Positions can be displayed simultaneously with the parent camera in the Graphics window and the 3D World window.

Images from positions can be displayed simultaneously in the 3D Video window, loaded to the Monitors, included in the PDF report.


The use of the positions is various. Here are some examples:


Modeling multisensor cameras. You can use positions instead or together with Groups.
Modeling PTZ cameras. You can simultaneously display several presets of a PTZ camera and a common control area. You can display presets in the 3D Video with image dividing. It is convenient to switch between presets.
Modeling Fisheye cameras. You can display several dewarped fragments from a Fisheye camera with real camera resolution on one image.
Selection of placing and camera parameters. To study and demonstrate the difference between positions, camera models or camera settings, you can save the camera settings into  positions and then activate these positions one by one.


The panel can be stretched horizontally and vertically by the mouse.


Positions have the following parameters, which can be quickly changed by noting checkboxes in the table or editing values:




Positions are named automatically. To rename select the cell with name by the mouse and type a new name. A single click on this cell selects a position in the table. At the moment of the click, the position is highlighted in the Graphics window and the 3D World window.


Double clicking on this cell copies the position to the active camera, similarly to the button Pos>Cam.


Be careful! when copying a position, the parameters of the active camera will be replaced by the position parameters.




The position is visible in the Graphics window.




The position is displayed in gray in the background.




If you set the Highlight greater than zero, the position is displayed in a more saturated color. If you set the Highlight less than zero, then the position is displayed less saturated, faded.


3D visible


The position is visible in the 3D World.




The position will be included in the Table of cameras.




After loading images from the parent camera to the Monitors window, images from the positions with selected Monitor cell will be loaded. Images from positions with the Monitor cell marked will be displayed in the 3D Video window with screen division if the Positions> Show switch is in the Positions or Cam + positions.




Paint position by specified color. Filling of camera view areas is colored only if the Pixel density visualization of this camera is disabled.

White color means no special color.



Below there are two tabs with tools:




Buttons on the Positions panel:


ОК - close the panel.


Add - add a position and copy parameters of the active camera to it.


Del - delete the position selected in the table.


<< >> - buttons allow you to sequentially copy positions in the table to the active camera.


Refresh – recalculate shadows of positions of the active camera in the Graphics window. If the 3D World window is open, the shadows will be recalculated in it as well.

Cam>Pos - Copy all parameters of the active camera to the position selected in the table.


Be careful! when copying, position parameters will be replaced by active camera parameters.


Pos>Cam - Copy a position selected in the table to the active camera. Beforehand select a position in the table by a single click .


Be careful! when copying, the parameters of the active camera will be replaced by the position parameters.


You can also copy a position to the camera by double-clicking on the line with the position.


Options for all active camera positions


Combine -  positions combined with the active camera are at the same point as the parent camera. Combined positions will be selected, moved, copied with the camera. When positions are selected together with the camera, you can control the view of the view areas of all positions simultaneously using the buttons of the "View" button group on the Toolbar.

You can assign the same Camera model to all positions, change the parameters of all positions at the same time, as you can change the parameters of all selected cameras using the Assign to selected cameras item of the context menu of the boxes with camera parameters.


Combined positions can be displayed simultaneously in the 3D Video window.

Combined positions are suitable for modeling multisensor cameras, presets for PTZ cameras and Fisheye camera dewarped fragments.

If this checkbox is not checked, then the position locations are not tied to the active camera. Not combined positions can be used to store and compare different placement options and parameters of the same camera.


Show Names - displays position names.


Show icons - display camera icons at the positions.



Multisensor camera


The tab contains special tools for modeling multisensor cameras using positions.


Number of sensors - the number of modules video sensor + lens in the camera. A multisensor camera should have more than one module.


Angle between sensors - the angle between the main optical axes of the lenses of the adjacent camera modules. You can enter the value of the angle in degrees or choose one of automatic calculations of the angle.


Horizontal - module lenses will be pointing horizontally. The angle between the modules will be calculated automatically so that there are no dead zones. View areas will be connected without intersections.


When the cameras are directed along the horizon, their view areas become infinite.

Set the Maximum drawing distance of the view area. Do not keep calculation of shadows constantly turned on.

Tilted - module lenses will be tilted in the same angle as the active camera is tilted. The angle between the modules will be calculated automatically so that there are no dead zones. If the modules are tilted, then a small intersections of their view areas are inevitable.


Add sensors - add new positions according to specified number of sensors. Rotate the positions with the angular step equal to the specified angle between sensors.


Hide nonselected parent camera - make the parent camera invisible if it is not selected. Selected parent camera will remain visible.


After automatic creation of the modules, they can be edited as usual camera positions.
