Practical guidelines to understanding the Field of View of TotaLite Sensor
The TotaLite Sensor offers a field of view with 60 degrees horinzontaly and a 45 degrees in the vertical direction.
Normally the field of view becomes a section of a cone, expanding the farther the distance from the target gets.
Coverage grows linearly, because Field of View is a fixed cone, every extra meter of slope distance adds exactly the same increment of approximately 1.155 meters horizontally from the camera pinhole. At maximum range we can expect a half span of +-40.41 meters of a total of 80.83 meters in full span.
The same will happen vertically, but with an increment of ~0.828 m/m, given the field of view is narrower. At full range, which is 70, we can expect a half span of +-28.99m and a full span of approximately 58m.
Coverage at distance
| Distance | H half-span | H full span | V half-span | V full span |
|---|---|---|---|---|
| 10 m | ± 5.77 m | 11.55 m | ± 4.14 m | 8.28 m |
| 20 m | ± 11.55 m | 23.09 m | ± 8.28 m | 16.57 m |
| 30 m | ± 17.32 m | 34.64 m | ± 12.43 m | 24.85 m |
| 40 m | ± 23.09 m | 46.19 m | ± 16.57 m | 33.14 m |
| 50 m | ± 28.87 m | 57.74 m | ± 20.71 m | 41.42 m |
| 60 m | ± 34.64 m | 69.28 m | ± 24.85 m | 49.71 m |
| 70 m | ± 40.41 m | 80.83 m | ± 28.99 m | 57.99 m |
