Study Notes
Drone Mapping Acquisition
- Before flying, ensure you have a Part 107 certificate, registration, and insurance
- Use a double grid pattern for exterior acquisition, and set your settings in advanced mode
- Set a 75/75 overlap with a 70° camera tilt, and fly at an altitude of 150-200 ft
Point of Interest Mode
- Use DJI Go4 and set up a point of interest mode to create three circles around the subject
- Set a 15 ft deviation and elevation between each flight run
- Tilt the camera down to eliminate sky from the images
- Limit deviation between tilt angles to prevent issues
Acquisition Considerations
- Be aware of firmware compatibility issues with older drones and newer applications
- Use caution when updating firmware or apps to avoid causing problems
- Consider using different acquisition applications if needed
Data Review and Upload
- Review images to ensure they are not blurry, overexposed, or pointing in the wrong direction
- Use the Drone Deploy app to direct upload from the app while connected to the drone (optional)
- Check and back up data after each mission to ensure quality and prevent issues
Creating a Project in Drone Deploy
- Create a new project and set up the project area carefully, as this is a critical part of the workflow
- Set the processing area to focus on the area around the building, excluding unnecessary photos
- Adjust the processing area to include required photos, if needed
Pre-Flight Preparations
- Ensure possession of a Part 107 certificate, registration, and insurance before flying
- Set up drone in advanced mode with a double grid pattern for exterior acquisition
Flight Settings
- Maintain a 75/75 overlap with a 70° camera tilt during flight
- Fly at an altitude of 150-200 ft to capture optimal images
Point of Interest Mode
- Use DJI Go4 to create three circles around the subject in point of interest mode
- Set a 15 ft deviation and elevation between each flight run for comprehensive coverage
- Tilt the camera down to eliminate sky from the images and limit deviation between tilt angles
Drone Compatibility and Maintenance
- Be aware of firmware compatibility issues with older drones and newer applications
- Exercise caution when updating firmware or apps to avoid causing problems
- Consider using alternative acquisition applications if necessary
Data Quality Control
- Review images to ensure they are not blurry, overexposed, or pointing in the wrong direction
- Directly upload images to the Drone Deploy app from the drone (optional)
- Check and back up data after each mission to ensure quality and prevent issues
Setting Up a Drone Deploy Project
- Create a new project and carefully set up the project area to focus on the critical parts of the workflow
- Set the processing area to focus on the area around the building, excluding unnecessary photos
- Adjust the processing area to include required photos, if needed
Uploading and Annotating 3D Models
- Uploading 3D textured mesh to SketchFab allows for easy navigation, embedding, and real-time spinning/animation of the model.
- SketchFab offers advanced controls for lighting, grain, sharpness, and annotations, with no size limitations.
Annotating SketchFab Models
- Annotations in SketchFab enable adding clickable buttons to the model, linking to other models, websites, or virtual tours.
- Annotations connect exterior and interior models, allowing users to jump between them.
- Editing 3D settings, adding a starting view, and setting rotation/camera orientation controls the user's experience.
Creating Matter Tags in Matterport
- Create a starting area in Matterport, which is the first area users see when entering the building.
- Add matter tags to jump from interior models to exterior models or external websites.
- Use link shorteners to track users jumping from interior to exterior models.
Product Tags and Virtual Storefronts
- Add product tags in Matterport to sell products directly from virtual stores.
- Create virtual storefronts by adding product tags and links to external websites.
- Use matter tags to create a mini landing pad for products and link to external websites.
Publishing and Sharing Models
- Brand and unbrand links in Matterport to share models with Realtors and clients.
- Use unbranded links when sharing with Realtors to avoid regulatory issues with MLS.
- Share iframe links from SketchFab with clients to embed the model on their website.
- Share branded links for Zillow to view exterior models and go to the realtor's website.
Hotkeys and Multiple Starting Points
- Use hotkeys in Matterport to create multiple starting points and share links on SketchFab.
- Create multiple starting points in Matterport to allow users to enter homes from different locations.
3D Modeling and Teleportation Devices
- Remember saved views, but start locations are not automatically saved.
- Corner shots must be set manually to save correct starting locations.
Sharing 3D Models with Clients
- Share 3D models with clients using links on SketchFab.
- Clients can embed the model on their website using the provided link.
- Auto-start turntable animation can be enabled to make the model more interactive.
Embedding 3D Models
- Embedding models allows real-time viewing on webpages.
- Be cautious not to overload the GPU with too many models, causing them to shut down.
- Edit point clouds to change things like hiding/showing objects (e.g., cars).
Editing and Teleportation
- Use pre-select annotation to allow people to teleport inside the model.
- Editing point clouds allows for changes to the model and teleportation capabilities.
Deliverables for Clients
- Provide clients with links to the 3D model on SketchFab.
- Give clients the embed code to add the model to their website.
Recap of 3D Modeling Process
- Acquire imagery inside a building using a 360 camera and Matterport software.
- Create a 3D textured mesh of the exterior using Drone Deploy and a formulaic image acquisition strategy.
- Post-process the outside and inside models.
- Host models online and link them together.
- Provide deliverables to clients (links and embed codes).
