Embodiment Construction

[0084] The present invention will be further described below in conjunction with specific examples.

[0085] The invention provides a method for measuring the width of an object based on a single-lens reflex camera, comprising the following steps:

[0086] Step 1. Determine the station: According to the width of the target, select a position at a certain distance from the target as the station, and set up a tripod on the station, place the SLR camera on the tripod, and place the station between the station and the target. The selection of the distance is subject to the complete shooting of the target by the SLR camera;

[0087] Step 2, arrange reference points: start from the midpoint of the tripod to draw two straight lines to the target, and arrange 3 reference points on the two lines respectively, among which the one closest to the tripod is the first reference point, which is the closest to the target The third reference point is the third reference point, and the second ...

Abstract

The invention discloses a method for measuring width of an object based on a single lens reflex. The method comprises steps of: erecting a tripod at a proper distance away from the object arranging the single lens reflex on the tripod, and arranging three reference points on connections lines between the center of the tripod and the object so as to shoot the target and the reference points to obtain pictures; measuring the actual distances of the reference points, the corresponding picture pixel distances and the corresponding pixel distance of the object; and inputting the measured data into a complied computing program to obtain the width of the object. The method is advantageous in that the measurement device such as the single lens reflex is common, light, highly applicable to environment, easy to operate, and high in measurement precision and can be used by specialists and laymen.

Description

technical field [0001] The invention relates to a method for measuring the width of an object, in particular to a method for measuring the width of an object based on a single-lens reflex camera. Background technique [0002] The measurement of object width is a problem often encountered in daily life, scientific research and engineering. The more commonly used width measurement method in daily life is the traditional contact measurement method, that is, using a tape measure for width measurement. The more commonly used width measurement methods in engineering are tape measure width measurement, theodolite width measurement, and total station width measurement. [0003] Tape width measurement belongs to the traditional contact measurement method, which uses a tape measure to measure directly on the 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 ...
