A method for measuring the height of an object

Abstract

The invention discloses a method for measuring the height of a target object, and the method comprises the steps: photographing the target object, measuring the photographing height and inclination angle of the target object, the pixel height of the target object in a picture, and a vertical pixel distance from the bottom of the target object to the lower edge of the picture; carrying out the photographing of reference points, placing two reference points on the ground, carrying out the photographing of the reference points at the same photographing inclination angle, measuring the photographing heights of the reference points, the distances from the reference points to a projection point of the center of a camera lens on the group, and a pixel distance between the two reference points in the picture; calculating the photogrammetric parameters through the measurement data of the reference points; and calculating the actual height of the target object through the measurement data of the target object and the photogrammetric parameters. The measurement equipment is simple, and the measurement equipment is portable. The requirements for the operating environment are not high, and the application range is wide. The method has the remarkable advantages for the measurement of a dynamic target object.

Description

technical field [0001] The invention relates to a method for measuring the height of an object. Background technique [0002] Object height measurement is a problem often encountered in daily life, engineering and scientific research. The more commonly used height measurement method in daily life is the traditional contact measurement method, which uses a ruler for height measurement. The more commonly used height measurement methods in engineering are ruler height measurement, theodolite combined with steel ruler height measurement, total station height measurement, and laser distance measuring altimeter height measurement. [0003] Using a ruler to measure height is a traditional contact measurement method, which is to use a ruler to measure directly on an object. The advantage of this measurement method is that good measurement accuracy can be guaranteed within the measuring range of the tape measure, the operation is simple and quick, and it is suitable for the measure...
