Data Collection Guide for Intel® Insight Platform
Caution |
|
The dataset (for example images with geolocation and optional but recommended Ground Control Points (GCPs) information) have to be obtained on the field before using the Intel® Insight Platform. A good dataset is required to automatically produce results with high quality and accuracy.
To gather a good dataset, follow the recommended steps below:
1. Design the Image Acquisition Plan. It's important to design a good image acquisition plan with the following considerations:
- Type of project (aerial, terrestrial, mixed)
- Type of terrain/object
- Type of camera
- Purpose of the project
- Image rate that the images are taken
- Distance (flight height) at which the images are taken and with which angle to take the images
- Path(s) to follow to take the images
For aerial projects, this also implies:
- Select corridor path or regular grid and/or circular grid.
- Decide whether terrestrial images will be used.
- If several flights are needed to cover the full area, design the area to cover with each flight.
2. Configure the Camera Settings. The camera settings used to acquire the images need to be configured. Wrong configuration can result in images with blur, noise, distortions, and so forth.
3. Georeferencing the images using a camera with built-in GPS.
4. Get GCPs on the field or through other sources (optional but recommended). Using GCPs requires planning how many GCPs have to be acquired, and where and how they have to be measured.
Things to Consider as you Plan
- Compute the Flight Height for a given Ground Sampling Distance (GSD)
- Select Camera Focal Length and Flight Altitude Considering the Desired Ground Sampling Distance and Terrain to Map
- Image Acquisition and Flight Planning
- How to include GCPs in the project
- Number and Distribution of Ground Control Points (GCPs) in Corridor Mapping
- How to map and measure Pole and Tower Structures
- Compute the Image Rate for a given Frontal Overlap
- Verify Overlap in Images on Intel® Insight Platform
- Vertical and Oblique imagery
- Check Image Quality for Intel® Insight Platform
- Processing large datasets
