Japanese Patent JP7282578
Kind Code:
B2
Abstract:
To provide an angle measuring device capable of easily measuring an angle without using a dedicated tool.SOLUTION: An angle measuring device 1 includes: an image acquisition section 21 for acquiring a picked-up image; a display control section 22 for displaying the picked-up image on a display device as a display image; an auxiliary line generation section 23 for generating a vertical center line passing through the center of the display image and extending in a vertical direction, and a horizontal center line passing through the center of the display image and extending in a horizontal direction; an observation point acquisition section 24 for acquiring an observation point positioned downward by a predetermined distance from the center of the display image on the vertical center line; a target point acquisition section 25 for acquiring a first target point and a second target point on the display image; an intersection acquisition section 26 for acquiring a first intersection which is an intersection of a perpendicular drawn from the first target point and the horizontal center line, and a second intersection which is an intersection of a perpendicular drawn from the second target point and the horizontal center line; and an angle detection section 27 for detecting an angle formed by a straight line connecting the first intersection and the observation point, and a straight line connecting the second intersection and the observation point.SELECTED DRAWING: Figure 1
