What is it and how does it work?

WHAT IS IT?

The iGUIDE PLANIX system by Planitar features a Ricoh THETA Z1 360° camera combined with a time-of-flight 2D laser scanner with a long range.

The iGUIDE uses a two lens design and the camera does not rotate, which reduces parallel errors and stitching artifacts. The camera takes two images to create a 360 panorama. Systems which do not use 360 cameras must rotate which can cause problems in the captured images being stitched together to make a 360. As an example a camera using a 20 mm wide angle has an angle of view of approximately 94 degrees so it will require 4 photos to complete a 360 panorama.

A big advantage to using this type of camera is speed, taking two photos each with 180 degrees and creating a  360 view from one location without having to rotate the camera for the next photograph. Chances of misaligning the two photos in extremely minimal unless the camera moved for some reason.

SCANNING

Lidar-based systems, such as iGUIDE use Time-of-Flight Laser Measurement to produce accurate laser point cloud. Floor plans created from such data have the highest accuracy. In the case of iGUIDE the uncertainty is 0.5%.

Time-of-flight laser measurement error does not depend on the distance measured, it is always constant. It means that no matter how large or small a room is, its measured size may be off by the same fixed amount, say one inch. It is only when several rooms are stacked together when measuring a floor, the overall floor plan error may somewhat grow with the size of the floor, mostly depending on the number of rooms.

If you compare measurement accuracy of LIDAR vs structured light 3D scanner or 3D structure from images technologies there is an important difference. For structured light image measurements, the error grows fast with measured distance. Systems using structured light require more camera positions and increase the scan time . Typical errors or uncertainty are around 1% range. The larger the space, the larger the accumulated error.

LIDAR, Time-of-Flight Laser Measurement error does not depend on the distance measured, it is always constant. It means that no matter how large or small a room is, its measured size may be off by the same fixed amount, say one inch. It is only when several rooms are stacked together when measuring a floor, the overall floor plan error may somewhat grow with the size of the floor, mostly depending on the number of rooms.

When property square footage is computed from floor plans, the resulting percentage error in square footage is twice the percentage error in the floor plan measurements. Structured light systems will typically have a 2% error in square footage and LIDAR systems will be well below 2% with lots of headroom.

The 2% level is important, because it is the maximum allowable square footage error in several property measurement standards, like the BOMA standards for commercial real estate or the Alberta Residential Measurement Standard.

How It All Comes Together

The combined 360° imagery and 2D laser point cloud data allow for not only constructing accurate floor plans, but also making measurements in 3D space.

The camera data is processed through the iGUIDE platform to produce a 3D tour with floor plans and property measurements.

Due to the long range of the lidar, the iGUIDE camera needs fewer camera positions to collect the necessary data and its onsite capture speed is about the same as with 360° cameras while at the same time providing much more accurate measurement data for constructing floor plans.

A 1500 sq ft home can be captured in as little as 20 to 30 minutes, depending upon site conditions.

The floor Plan and the 360 image are side by side in the iGUIDE viewer for quick and easy navigation. This gives a viewer the best possible option of how they can navigate through the space. Much faster and more intuitive than a doll house scenario.

The on screen measure system comes in handy for furniture placement or any other items where you want to see if something will fit.

iGUIDE Floor Plans

These provide a visual overview of your property interior.

iGUIDE knows the importance of superior-quality floorplans and the value they have on your listing. Every iGUIDE comes with floorplans to drive engagement. In today’s competitive market continually standing out from the rest; and having a professional and detailed floor plan can make all the difference. iGUIDE offers two floor plan choices, both are interactive with the viewer, extremely intuitive and easy to use.

Standard vs Premium Floor Plans

Two different types of floor plans. Premium includes more details such as door swings, appliances, and fixtures. This allows you to really get to know the space in a more intimate way. Standard also provides the information you need to get a thorough understanding of the floor plan layout. Compare the two and decide which one may be more suitable to your needs.

Floor Plan Colors

A number of different color combinations to best suit your personal preference. We rowse through our selection and select the one that best speaks to you. Every floor plan has been designed to ensure our customers are getting the most details.
