This article describes the field of view (FOV) of the GX1's LiDAR and cameras.
Field of view by sensor
The GX1 has two sensors, each with its own FOV:
Sensor | Horizontal FOV | Vertical FOV |
|---|---|---|
LiDAR | 360° | 95° (55° above horizontal, 40° below) |
Cameras | 360° | 142° (71° above horizontal and below) |
The horizontal FOV is the angular coverage around the GX1. The vertical FOV is the angular coverage above and below horizontal. The LiDAR vertical coverage is asymmetric, with more coverage above horizontal than below.
What the FOV captures
The FOV determines what the GX1 records from any one position. Anything outside the FOV is not captured until the device is moved or its orientation changes. This includes:
Surfaces directly above or below the device when the vertical FOV does not reach that far.
Surfaces blocked by the operator's body, arms, or mounting hardware.
To cover these gaps, move through the environment, vary the device's orientation, or scan from multiple positions.
Mounting and the FOV
The mounting method affects how much of the FOV is usable. Handheld scanning at hand height puts the operator's body within the FOV. Raising the GX1 above the head, mounting it on a survey pole, or using a backpack mount keeps the operator below the sensors and clears the panorama.
Because the LiDAR vertical FOV is asymmetric, ground coverage directly below an elevated mount is more limited than ceiling or overhead coverage. To fill gaps directly under the operator on Backpack or Survey Pole mounts, plan the scan path to revisit the same area from multiple positions.
