Video Format Overview
Horizons requires that Video from a multi-camera capture platform is loaded in a specific format. Video data captured from a moving platform is made up of two primary data sources: Video Images and Location. Each Video image is accompanied by coordinate data that is sufficient to position the image capture location on a map. These two data sources are linked via a synchronization file. Optionally, camera calibration data can also be supplied to enable measurement tools for use with images, and to project item locations onto the image.
The information you need is available in the following sections:
- Video Naming Conventions and File Structure
- Video Data
- Video Location Data
- Synchronization File for Video
Video Imagery Data
Take
Each Take is usually representative of a set of frames collected (by all cameras) sequentially during a single capture pass.
Pixel Size
Pixel sizes should be specified in mm, with the width and height (PSX, PSY) of each pixel given. This may be obtained using the ratio of sizes of the sensor in mm and in pixels. If the physical size of the sensor in mm is not known, search online for the sensor type.
