Abstract

The invention discloses a method and a device for monitoring the height of a building and a distance between buildings. The method comprises the following steps of: when a mobile terminal is vertical to a horizontal plane, shooting and storing a first image of the building; obtaining a first visible angle of a camera of the mobile terminal in a vertical direction, a first height of the building in the first image, and a first distance from the top of the building to the upper edge of the first image; when the mobile terminal is forward or backward moved for a pre-set distance, shooting and storing a second image of the building; obtaining a second visible angle of the camera of the mobile terminal in the vertical direction, a second height of the building in the second image, and a second distance from the top of the building to the upper edge of the second image; and calculating according to the first and second visible angles, the first and second heights, the first and second distances and the pre-set distance to obtain the distance between the buildings and the height of the building. According to the method and the device disclosed by the invention, a photographer can measure the distance between the buildings and the height of the building without depending on distance measurement devices.

Description

technical field [0001] The invention relates to the technical field of photogrammetry, in particular to a method and a device for monitoring the height of a building and the distance from the building. Background technique [0002] In some areas of people's daily life, it is sometimes necessary to measure the height and displacement (distance from the viewer) of buildings. However, in the process of measurement, it usually relies on some distance measuring instruments, such as gyro theodolite, electronic speed measuring instrument, tablet instrument, etc., which are not convenient for visual inspection and complicated to operate. [0003] With the rapid development of electronic science and technology, some mobile terminals with camera functions, such as smart phones and personal digital assistants, have been gradually popularized and used. How to use the mobile terminal with the camera function to realize the measurement of the height and displacement of the building is wo...
