When a panorama is created the entire space within range is measured and photographed. Multiple panoramas for different spaces are then combined to create an entire representation of the house in raw data. This raw data is then used by professional drafters to create the iGUIDE and draw floor plans.
The images are just as important as the laser measurement data in this process. When the drafters look at the measurement data they will often refer to the images to determine what was measured.
IMPORTANT NOTE: The mode dial on the DSLR must be set to M to create a panorama.
The procedure for creating a panorama is mostly the same regardless of shooting conditions, property size. Here is the process step by step:
- Turn the lasers on by tapping the toggle button beneath the word laser. This will only have to be done once per shoot and is required for measurements to be taken.
- Press the +1 button. This creates a name in Survey for the panorama. This name will be a number starting with 000 and growing by one each time the button is subsequently pressed. It will also be visible next to the house name and floor name at the bottom of the interface. Panoramas can be given custom names from the Pano screen. This is a handy feature if you want to label a pano for room labelling later.
- Place the camera in a space that you wish to measure. It is not required that it be in the middle of the room or anywhere in particular but the camera should have an unobstructed view. Because a 360 degree panorama doesn’t require the same kind of framing as a regular still image, the cameras location it is much more flexible with regard to the images.
- Point the camera at something of interest or something that identifies the space. The first thing people will see when they load the panorama later will be what it was first directed at.
- Rotate the camera slightly to confirm that it is resting in one of the three positions on the rotator. It doesn’t matter which of the three positions you choose and you can ignore all of the markings on the rotator. It is preconfigured during assembly.
- Level the camera using the spirit level on the dslr hotshoe mount. Level the camera at the start of each panorama and don’t change it when transitioning from the first position to any subsequent ones.
- Tap the button on the back of the dslr that turns on the live view. To the right of the viewfinder, next to a red dot, with an image of a camera back on it. This will turn on the cameras LCD so you can see what the camera sees.
- While looking at the dslr tap the rectangle in survey that says daylight, this is a white balance selection and will affect the colors of the panorama images. A dropdown will appear with white balance options to select. Select different option and look at the lcd to judge their accuracy. Choose the white balance that suits the scene by eye.
- Rotate the wheel on top of the dslr that’s net to the shutter button. This will control the brightness of the image that appears on the lcd. Choose a suitable brightness for the scene.
- Tap the button that looks like a camera body or the Shoot Panorama button. The camera will take three pictures and merge them in camera to create an HDR composite images. You will see a box that says processing image while this takes place. When complete a preview image will be displayed that can be pinched to zoom.
- Rotate the camera clockwise to the next position on the rotator and tap the Shoot Panorama button again. Another preview image will appear representing the scene that was just captured.
- Rotate the camera clockwise to the next position on the rotator and tap the Panorama Shoot button for one final time to capture the last image required to complete the panorama.
When complete the three thumbnail images for the shot indicators should be populated with three distinct images.
The laser measurement data for the space has also been captured but isn’t visible. Tap on the small white icon in the corner of the grey box in the bottom right hand corner of the main preview image. This will cause the canvas to expand allowing you to see all the data that has been captured thus far.
The color of the data is important, here are the definitions of each colour:
LIGHT BLUE: This is laser data that has just been captured or that has been selected.
DARK BLUE: This data represents all the measurements for all panorama that are not currently selected. This data cannot be moved or rotated.
GREY: This data is gathered during automatic mapping mode. It cannot be moved or selected.
GREEN: This data represents what is in the camera systems field of view. It’s what the camera is currently seeing in real time.
YELLOW: When a move button is tapped the light blue data will change to yellow signifying that it can be moved on-screen using one finger and drag. Two fingers and drag to rotate.
