Method and system for measuring angles based on 360 degree images

摘要

A method of measuring an angle includes orienting a measurement device at a reference position characterized by a reference angle. A first panoramic image defined by a predetermined range of elevation angles is acquired where the first panoramic image includes an object. A first bearing of the object in relation to the reference angle is determined and the measurement device is rotated to a measurement position characterized by a measurement angle. A second panoramic image defined by the predetermined range of elevation angles is acquired where the second panoramic image includes the object. A second bearing of the object in relation to the reference angle is determined. The measurement angle is computed as a function of the first bearing and the second bearing.

1. A method of determining an orientation of a measurement device, the method comprising:
orienting the measurement device at a first position; acquiring a first panoramic image from the first position using an imaging device, the first panoramic image including a plurality of object points; determining three-dimensional coordinates of the measurement device at the first position using a location measurement device; repositioning the measurement device to a second position different from the first position; acquiring a second panoramic image from the second position using the imaging device, the second panoramic image including the plurality of object points; determining three-dimensional coordinates of the measurement device at the second position using the location measurement device; identifying the plurality of object points in the first panoramic image and in the second panoramic image using a processor; and determining the orientation of the measurement device at the second position using the processor, the orientation determined based on the three-dimensional coordinates of the measurement device at the first position and the three-dimensional coordinates of the measurement device at the second position.
