Description

[0001] APPARATUS AND METHOD FOR MEASUREMENT CONTROL OF CRACK USING SMARTPHONE [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an apparatus and a method for managing cracks using a smartphone, and more particularly, to a smartphone capable of measuring a size of cracks and managing cracks The present invention relates to an apparatus and a method for managing cracks in a crack.

Concrete structures commonly used in buildings, tunnels, bridges, etc. are damaged and aged over time.

In order to maintain the function of the damaged and deteriorated concrete structure and to prolong its life, continuous maintenance and inspection of the concrete structure are necessary.

The most basic survey for the inspection of concrete structures is the appearance survey, and the examination of cracks on the surface of concrete structures in appearance survey is an important factor to judge the usability and safety of the concrete structure.

In order to investigate cracks on the surface of concrete structures, a visual observation was usually used.

However, the visual observation has a disadvantage in that it is difficult to measure the width of objective cracks due to the subjectivity of the measurer and the reliability of the measured width is very low.

In this respect, a technique for measuring the cracks on the surface of concrete structures is being conducted by analyzing the images of the cracked portions.

From the above viewpoints, Japanese Patent Application Laid-Open Nos. 10-2002-0077250 and 10-2004-0020261 disclose an apparatus and a method for processing an image of a concrete structure to measure a crack.

However, such a device is mounted on a vehicle or mounted on its own transport vehicle, making it difficult for a user in the field to measure cracks on the surface of concrete structures in real time in the field.

As a conventional technique for crack measurement, a crack measurement is performed using a separate crack measurement device including a load cell, and crack management is performed by hand, which is managed by preparing a crack management register after measuring a crack There is an inefficiency in which crack measurement and management are performed separately.

These existing techniques also require continuing management due to the characteristics of cracks in concrete structures that are generated and maintained over time. However, existing methods that require measurement and management separately require skilled personnel, There was also a problem.
