Remote positioning

摘要

A method for determining a distance to a target point located approximately at ground level includes aiming a measurement device at the target point, determining a tilt of the measurement device using tilt sensors, and determining a height of the measurement device above the ground. A position of the target point may be determined using the tilt and height of the measurement device, a position of the measurement device, and a bearing to the target point.

1. A method for determining a horizontal distance between a first location and a target point located approximately at ground level, the method comprising:
at the first location:
aiming the handheld measurement device at the target point; anddetermining a tilt of the handheld measurement device while aiming the handheld measurement device at the target point, the tilt determined using one or more tilt sensors; thereafter computing the horizontal distance between the first location and the target point using the tilt of the handheld measurement device and a fixed height of the handheld measurement device above the ground, wherein the horizontal distance between the first location and the target point is computed without measuring a distance between the handheld measurement device and the target point and without measuring a height of the handheld measurement device at the first location.
