Description

Method for generating an alarm based on crane video and apparatus thereof The present invention relates to a method for generating an alarm based on the results of analyzing an image, and more specifically, to a method for generating an alarm for a crane workplace based on an image captured by a crane, and to an apparatus for implementing the method. Cranes are large pieces of equipment used to move various heavy loads; as they are used to transport weights ranging from several tons to tens of tons, accidents involving them tend to result in significant human and material damage. To prevent crane-related accidents, safety systems centered on crane equipment have traditionally been utilized. However, since the aforementioned crane safety systems are all equipment-centric, existing systems tend to be somewhat less efficient in addressing human-caused crane accidents; therefore, technology is required to complement this. FIG. 1 is a schematic diagram showing an example of an overall system to which the present invention is applied. Figure 2 is a block diagram reconstructing another example of the entire system described in Figure 1. FIG. 3 is a schematic drawing showing the front and side sections of a goliath crane to which the present invention is applied. FIG. 4 is a block diagram illustrating an example of a crane image-based alarm generation device implementing the method according to the present invention. FIG. 5 is a diagram exemplarily showing a first image generated by a camera in the present invention. FIG. 6 is a diagram schematically illustrating an example of a second image generated by the method according to the present invention. FIG. 7 is a diagram schematically illustrating another example of a second image generated by the method according to the present invention, following FIG. 6. FIG. 8 is a flowchart illustrating an example of a method according to the present invention. The present invention is capable of various modifications and may have various embodiments; specific embodiments are illustrated in the drawings and described in detail in the detailed description. The effects and features of the present invention, and the methods for achieving them, will become clear by referring to the embodiments described below in detail together with the drawings. However, the present invention is not limited to the embodiments disclosed below but can be implemented in various forms. Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings. When describing with reference to the drawings, identical or corresponding components are given the same reference numerals, and redundant descriptions thereof will be omitted. In the following embodiments, terms such as first, second, etc. are used not in a limiting sense, but for the purpose of distinguishing one component from another component. In the following embodiments, singular expressions include plural expressions unless the context clearly indicates otherwise. In the following embodiments, terms such as "include" or "have" mean that the features or components described in the specification are present, and do not preclude the possibility that one or more other features or components may be added. Where an embodiment can be implemented differently, a specific process sequence may be performed differently from the order described. For example, two processes described consecutively may be performed substantially simultaneously or proceed in the reverse order of the description. FIG. 1 is a schematic diagram showing an example of an overall system to which the present invention is applied. The entire system (10) of the present invention illustrated in FIG. 1 may include a goliath crane (100), a heavy object (110), a hoist (120), a camera (130), and an alarm generating device (140). In FIG. 1, the goliath crane (100) is a crane for moving heavy objects (110) up, down, left, and right. Generally, the goliath crane (100) is a type of super-large gantry crane, referring to a huge crane designed to lift and move large heavy objects at a shipyard or block assembly site. It consists of a base frame, a rail system, a tower, a hoist, a boom, and a control room, but for convenience of explanation, only the necessary components are highlighted in FIG. 1. Although the goliath crane (100) is shown as a representative example in FIG. 1, the alarm generation method according to the present invention does not limit the type of crane to a specific type, so unlike FIG. 1, it can be applied to various cranes such as jib cranes, tower cranes, overhead cranes, etc., in addition to the goliath crane (100). The heavy object (110) refers to a cargo that is moved up, down, left, and right by a goliath crane (100). Although it is depicted in FIG. 1 as a rectangular cargo with a rectangular cross-section, the present invention is not limited thereto, so it may be a cargo of various shapes with a cross-section such as a ci
