Firsthand accounts from the field

“Today I had the chance to try out Dot3D and it was amazing. It's hard to understand the benefits of a tool like this until you actually try it out in the field. What would have taken about a day and a half can now be completed in half a day...”

"What I like about Dot3D is that it has a fast processing time, yet still produces high enough accuracy that it's very useful."

"Dot3D is very effective when surveying current conditions like this. Surveys can be completed in less time than with a terrestrial laser scanner. Also, the density of the points is high, making it easy to understand the location."

"I used PotreeDesktop to visualize point cloud data acquired on an iPhone LiDAR. The colors look beautiful and the zoom in/out is very smooth and convenient! I used the iPhone LiDAR app Dot3D."

"Today we are inspecting a newly constructed building that stretches over 50m horizontally. We spent 10 minutes scattering 10 Apriltags while taking photos of the buildings, then 15 minutes observing the Apriltags with drogger RTK, and finally 10 minutes scanning with Dot3D. After returning to the office, it took about five minutes to import the CSV and optimize it. We were able to output point cloud data that allowed us to accurately measure the building's dimensions."

“Point clouds with high density and high contrast are easier to trace. The point cloud density of DOT3D is too high, so it can be used in practice even if it is thinned to about 10%.”

“The image shows a residential lot in Tokyo. Dot3D measurement range: 150 to 250 m2. When I converted it to LAS, the data size was about 250MB. If 2GB is possible, it seems like it would be possible to process almost an entire residential site in Tokyo. If we can classify them to this extent, it seems that the amount of work required for drawing in 3D → and 2D can be significantly reduced.”

From Scan to Area Report with Shindler Solutions: ANSI Standards Made Simple
“How Schindler Solutions - A real estate media company in North Carolina - partnered with Mediatask to turn mobile seats into precise, NCREC-compliant floor plans and reports ready for appraisals and transactions.”
This case study highlights a streamlined "Scan-to-Plan" workflow that leverages Dot3D for high-accuracy building documentation. By utilizing Dot3D on handheld devices, users can capture comprehensive interior data of residential and commercial properties in a fraction of the time required by traditional methods. The process emphasizes precision, using Dot3D’s unique ability to incorporate external dimensional constraints and loop-closure algorithms to ensure that the resulting point clouds are accurate within a <2cm margin—far exceeding the reliability of standard consumer scanning apps.
Indoor Survey Mapping with iPhone 15 Pro and Dot3D
“Today, we embarked on an exciting journey of indoor survey mapping using our iPhone 15 Pro.
Our mission? To map the inside of a condo with survey-grade accuracy, projecting everything into State Plane coordinates, and create a point cloud that we can integrate into other spatial data like a drone point cloud.
To ensure accuracy, we set up numerous April targets around the condo. Not only did these targets help us tie our scans together, but we also used a Total Station to survey all these targets, carrying our geodetic coordinates indoors.”

Get started today with just an iPhone Pro (12 & up) or iPad Pro (2020 & up) with built-in LiDAR. If you prefer to start with a Windows or Android device, you’ll need an Intel RealSense or DPI external camera. The software trial is free on all platforms.
-
Pro is our most popular option for most iPhone/iPad users relying solely on their embedded LiDAR camera (iOS). Prime is a premium solution for leveraging external 3D cameras on Windows/Android or external GNSS receivers (i.e. Trimble DA2) on iOS.
-
YES! The use of coded targets (AprilTags) is one of the most important capabilities of Dot3D. Please click here to download Dot3D AprilTags for printing, and see here for several tutorials on their use. You also have the option to order a rugged set here.
-
Don’t worry! No automatic charges will occur. Once your trial ends, you’ll automatically revert back to FREE mode, still allowing scanning and testing, but with some limited functionality and NO EXPORTS. You may then upgrade to PRO or PRIME anytime.
