부피 및 중량 자동 측정 시스템Volume and weight automatic measuring system
본 발명은 부피 및 중량 자동 측정 시스템에 관한 것으로, 소포 또는 화물의 부피 및 중량을 자동으로 측정하는 부피 및 중량 자동 측정 시스템에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic volume and weight measuring system, and more particularly to an automatic volume and weight measuring system for automatically measuring the volume and weight of a vesicle or a cargo.
산업체의 각종 부품의 생산 시 또는, 우체국에서 처리하는 우편 택배물이나 각종 수하물 등의 접수 처리시, 정확한 중량 측정은 필수적이다.Accurate weighing is indispensable for the production of various parts of industry or for the reception of postal delivery and various baggage handling by post offices.
예를 들어, 산업체에서는 기구나 장치 부품의 중량 측정이 다양하게 요구되고, 우체국과 택배회사 등에서 처리하는 우편 택배물이나 각종 수하물은 중량에 따라 비용(요금)이 결정될 수 있기 때문에, 정확한 무게측정이 필요한 것이다.For example, in industry, weighing instruments and parts are variously demanded, and postal delivery and courier companies handle postal delivery and various baggage, so the cost (charge) can be determined by weight. will be.
그런데, 통상 산업체나 우체국 등에서는 지금까지 알려진 저울(소형 또는 대형 저울)을 구매하여, 저울 위에 무게를 측정하기 위한 피측정물 즉, 각종 부품이나, 우편 택배물이나 수하물 등을 단순하게 올려놓고, 중량을 측정하는 것이 일반적인 것이었다.[0003] In general, in industrial and post offices, a known scale (small or large scale) is purchased, and a subject to be measured for measuring the weight on the scale, that is, various parts, postal courier or baggage, Was measured.
도 1은 종래 피측정물의 중량 및 부피를 측정하는 시스템을 도시하고 있다.Fig. 1 shows a system for measuring the weight and volume of a conventional object to be measured.
도 1에 도시되어 있는 바와 같이 피측정물의 부피는 3개의 센서를 이용하여 피측정물의 가로 길이, 세로 길이 및 높이를 측정하고, 측정한 가로 길이, 세로 길이 및 높이를 이용하여 피측정물의 부피를 산출한다.As shown in FIG. 1, the volume of the object to be measured is measured by using three sensors to measure the width, length and height of the object to be measured, and the volume of the object to be measured is measured .
하지만, 도 1에 도시되어 있는 바와 같이 피측정물의 부피를 측정하는 3개의 센서 중 피측정물의 가로 길이 및 세로 길이를 측정하는 센서는 시스템의 외측에 노출된 상태로 위치한다. 이와 같이 센서가 시스템의 외측에 노출됨으로써 작업자는 피측정물을 작업대로 이동시키거나, 작업대로부터 피측정물을 빼낼 때 센서에 부딪히지 않도록 주의해서 작업을 해야 한다. 또한, 종래 측정 시스템은 피측정물을 작업대의 한쪽 코너에 밀착시켜야 측정이 가능하다는 불편함이 있다.However, as shown in Fig. 1, among the three sensors for measuring the volume of the object to be measured, the sensor for measuring the transverse length and the longitudinal length of the object is located exposed to the outside of the system. In this way, the sensor is exposed to the outside of the system so that the operator must take care not to move the workpiece to the workbench or to hit the sensor when removing the workpiece from the workbench. In addition, the conventional measurement system has an inconvenience that measurement can be performed only when the measured object is brought into close contact with one corner of the work table.
본 발명이 해결하려는 과제는 피측정물의 부피 및 중량을 측정하기 위해 피측정물을 작업대에 올려놓을 경우 센서와 부딪히는 불편함을 감소시키는 방안을 제안함에 있다.A problem to be solved by the present invention is to reduce the inconvenience when the object to be measured is placed on a work table to measure the volume and weight of the object to be measured.
본 발명이 해결하려는 다른 과제는 피측정물의 부피 및 중량을 측정하기 위해 피측정물을 작업대의 한쪽 코너에 밀착시켜야 하는 불편함을 감소시키는 방안을 제안함에 있다.Another problem to be solved by the present invention is to reduce the inconvenience that the object to be measured must be brought into close contact with one corner of the work table in order to measure the volume and weight of the object to be measured.
본 발명이 해결하려는 또 다른 과제는 피측정물의 단면적이 작업대의 단면적보다 큰 경우에는 피측정물의 부피를 측정할 수 있는 방안을 제안함에 있다.Another object of the present invention is to provide a method of measuring the volume of a workpiece when the cross-sectional area of the workpiece is larger than the cross-sectional area of the workbench.
이를 위해 본 발명의 측정 시스템은 평판 형상을 가지며, 저면에 위치하는 베이스, 상기 베이스의 상단에 평판 타입으로 형성되는 저울 상판, 일측이 상기 저울 상판과 밀착되며, 일정 길이를 갖는 막대 타입을 포함하는 연결부재, 상기 연결부재의 외측에 인출된 상태에서 외부로부터 가압되면, 상기 연결부재의 내측으로 인입되는 엑츄에이터, 상기 저울 상판에 좌측에 형성되는 좌측 거리 측정 센서부와 상기 저울 상판의 우측에 형성되는 우측 거리 측정 센서부 중 적어도 하나를 포함하는 거리 측정 센서부를 포함한다.To this end, the measurement system of the present invention includes a base having a flat shape, a base positioned on the bottom surface, a scale upper plate formed on a top of the base, a scale type bar having one side closely contacted with the scale upper plate, A left distance measuring sensor part formed on the left side of the balance upper plate, and a left distance measuring sensor part formed on the left side of the balance upper plate, And a distance measuring sensor unit including at least one of the right distance measuring sensor unit.
본 발명에 따른 부피 및 중량 자동 측정 시스템 및 이를 이용한 소포 접수 방법은 피측정물을 부피를 측정하는 센서부가 평상시에는 피측정물이 안착되는 측정 상판의 하단에 위치함으로써 사용자가 측정 상판에 피측정물을 올려놓는 경우, 센서부와 부딪힐 가능성을 줄어들게 된다.The automatic volume and weight measuring system and the vesicle receiving method using the same according to the present invention are characterized in that the sensor unit for measuring the volume of the object to be measured is positioned at the lower end of the measurement object plate on which the object to be measured is placed, The possibility of collision with the sensor unit is reduced.
또한, 기존 피측정물의 부피를 측정하기 위해서는 피측정물을 한쪽 코너에 밀착시켜야 하는데, 이 경우 코너의 위치에 따라 왼손잡이 또는 오른손잡이 모두를 만족시킬 수 없었다. 하지만, 본 발명은 피측정물을 코너에 밀착시키는 대신 사각 형상의 측정 상판의 일측면에 밀착시키면 되므로 왼손잡이 또는 오른손잡이 모두를 만족시킬 수 있다.In addition, in order to measure the volume of an existing object, the object to be measured must be brought into close contact with one corner. In this case, it is not possible to satisfy both left-handed and right-handed positions depending on the position of the corner. However, according to the present invention, the object to be measured can be brought into close contact with one side of the rectangular measurement top plate instead of being brought into close contact with the corner, thereby satisfying both left-handedness and right-handedness.
도 1은 종래 피측정물의 부피를 측정하는 시스템을 도시하고 있다.Fig. 1 shows a system for measuring the volume of a conventional object to be measured.
도 2는 본 발명의 일실시 예에 따른 피측정물의 중량 및 부피를 측정하는 측정 시스템을 도시하고 있다.2 shows a measuring system for measuring the weight and volume of a workpiece according to an embodiment of the present invention.

도 6은 본 발명의 일실시 예에 따른 좌우 거리 측정 센서부가 연장(늘어)된 경우를 도시하고 있다.6 shows a case in which the left and right distance measuring sensor unit is extended (extended) according to an embodiment of the present invention.
도 7은 본 발명의 일실시 예에 따른 좌측 거리 측정 센서부가 연장된 상태를 도시하고 있다.FIG. 7 shows an extended state of the left distance measuring sensor according to an embodiment of the present invention.
도 2는 본 발명의 일실시 예에 따른 피측정물의 중량 및 부피를 측정하는 측정 시스템을 도시하고 있다. 이하 도 2를 이용하여 본 발명의 일실시 예에 따른 피측정물의 중량 및 부피를 측정하는 시스템에 대해 상세하게 알아보기로 한다.2 shows a measuring system for measuring the weight and volume of a workpiece according to an embodiment of the present invention. Hereinafter, a system for measuring a weight and a volume of an object to be measured according to an embodiment of the present invention will be described in detail with reference to FIG.

In the lower part of the upper plate 225 of the balance as described above, the volume of the measured object is measured, (215) are connected to each other.
엑츄에이터(220)는 평상시에는 연결부재(230)의 외측으로 돌출되며, 가압하면 연결부재(230)의 내측으로 인입된다.The actuator 220 is normally protruded to the outside of the connecting member 230 and is drawn into the connecting member 230 when pressed.
깊이 측정 센서부(215)는 엑츄에이터(220)와 연동하여 동작한다. 부연하여 설명하면, 엑츄에이터(215)가 연결부재(230)의 외부로 돌출되면 깊이 측정 센서부(215)는 저울 상판(225) 아래로 인입되며, 엑츄에이터(215)가 연결부재(230)의 내측으로 인입되면 깊이 측정 센서부(215)는 저울 상판(225) 위로 돌출된다.The depth measurement sensor unit 215 operates in conjunction with the actuator 220. When the actuator 215 protrudes to the outside of the connecting member 230, the depth measuring sensor unit 215 is pulled below the scale upper plate 225 and the actuator 215 is moved to the inside of the connecting member 230 The depth measurement sensor unit 215 is protruded above the scale upper plate 225.
이와 같이 깊이 측정 센서부(215)는 평상시 저울 상판(225)의 아래에 위치함으로써 작업자는 깊이 측정 센서부(215)와의 부딪힘 없이 피측정물을 저울 상판(225)의 상단에 안착시킬 수 있다.Since the depth measurement sensor unit 215 is normally positioned below the scale upper plate 225, the operator can seat the measured object on the upper end of the scale upper plate 225 without colliding with the depth measurement sensor unit 215.
깊이 측정 센서부(215)는 피측정물과의 거리를 측정한다. 또한, 깊이 측정 센서부(215)는 저울 상판(225)에 안착된 피측정물과의 거리를 측정하기 위해 깊이 측정 센서부(215)가 저울 상판(225) 상단으로 이동한 경우에는 깊이 측정 센서부(215)에서 조사되는 광의 조사 방향은 저울 상판(225)과 평행한 상태를 유지한다.The depth measurement sensor unit 215 measures the distance from the object to be measured. When the depth measurement sensor unit 215 moves to the upper end of the scale upper plate 225 to measure the distance between the depth measurement sensor unit 215 and the measured object placed on the scale upper plate 225, The irradiation direction of the light irradiated by the unit 215 maintains a state parallel to the scale upper plate 225.
좌우 거리 측정 센서부(210)는 저울 상판(225)의 좌측 및 우측에 각각 하나씩 위치하며, 저울 상판(225) 상단에 안착된 피측정물과의 거리를 측정한다. 좌우 거리 측정 센서부(210)에서 측정한 정보를 이용하여 피측정물의 폭을 산출한다.The left and right distance measurement sensor unit 210 is positioned on the left and right sides of the scale upper plate 225 and measures the distance to the measured object placed on the upper end of the scale upper plate 225. The width of the object to be measured is calculated by using the information measured by the right and left distance measuring sensor unit 210.
높이 측정 센서부(205)는 저울 상판(225) 상단에 위치하며, 저울 상판(225) 상단에 안착된 피측정물의 높이를 측정한다. 이를 위해 측정 시스템(200)은 일측은 저울 상판(225)과 연결되며, 타측에는 높이 측정 센서부(205)가 연결되는 연결부재(230)를 포함한다. 연결부재(230)는 특정 길이는 갖는 바 타입으로 하단은 저울 상판(225)의 모서리 중앙에 위치한 엑츄에이터(220)가 내장될 수 있도록 길이 방향으로 일정한 폭을 갖도록 구성되며, 상술한 바와 같이 타측에는 높이 측정 센서부(205)가 연결된다. 일반적으로 연결부재(230)의 길이는 저울 상판(225)에 안착되는 피측정물의 높이보다 상대적으로 길게 형성된다.The height measurement sensor unit 205 is located at the upper end of the scale upper plate 225 and measures the height of the measurement object placed on the upper end of the scale upper plate 225. To this end, the measuring system 200 includes a connecting member 230 having one side connected to the scale top plate 225 and the other side connected to the height measurement sensor unit 205. The connecting member 230 is a bar type having a specific length and the lower end is configured to have a constant width in the longitudinal direction so that the actuator 220 located at the center of the edge of the upper plate 225 of the balance can be built in. A height measurement sensor unit 205 is connected. Generally, the length of the connecting member 230 is relatively longer than the height of the object to be measured which is placed on the scale upper plate 225.
이와 같이 본 발명의 측정 시스템은 저울 상판(225)의 하단에 위치한 로드셀을 이용하여 피측정물의 중량을 측정하며, 각종 센서부를 이용하여 피측정물의 부피를 측정한다.As described above, the measuring system of the present invention measures the weight of the object to be measured using the load cell located at the lower end of the upper plate 225, and measures the volume of the object using various sensor units.

도 3은 측정 상판의 상단에 피측정물을 안착하는 예를 도시하고 있다. 도 3에 도시되어 있는 바와 같이 깊이 측정 센서부(215)는 저울 상판(225)의 하단에 위치하고 있으며, 엑츄에이터(220)는 연결부재(230)의 외부로 돌출되어 있다.Fig. 3 shows an example of placing the object to be measured on the upper side of the measurement top plate. 3, the depth measurement sensor unit 215 is positioned at the lower end of the scale upper plate 225, and the actuator 220 is protruded to the outside of the connection member 230. As shown in FIG.
도 4는 피측정물을 이용하여 엑츄에이터를 가압하는 예를 도시하고 있다. 도 4에 도시되어 있는 바와 같이 피측정물이 엑츄에이터(220)를 가압하면, 엑츄에이터(220)는 연결부재(230)의 내측으로 인입되며, 깊이 측정 센서부(215)는 저울 상판(225)의 상측으로 돌출된다. 전원을 공급받은 각종 센서부(205, 210, 215)는 피측정물과의 거리를 측정한다.Fig. 4 shows an example in which the actuator is pressurized using the object to be measured. 4, when the object to be measured presses the actuator 220, the actuator 220 is pulled inward of the connecting member 230, and the depth measuring sensor unit 215 detects the depth of the upper surface of the scale upper plate 225 And protrudes upward. The various sensor units 205, 210, and 215, which are supplied with power, measure the distance from the object to be measured.
부연하여 설명하면, 엑츄에이터(220)를 가압하면, 엑츄에이터(220)의 구동과 연동되는 깊이 측정 센서부(215)는 저울 상판(225)의 상측으로 돌출된다. 저울 상판(225)의 상측으로 깊이 측정 센서부(215)가 돌출되면, 깊이 측정 센서부(215)를 포함한 좌우 거리 측정 센서부(210), 높이 측정 센서부(205)가 피측정물과의 거리를 측정한다. More specifically, when the actuator 220 is pressed, the depth measurement sensor unit 215 interlocked with the driving of the actuator 220 is protruded upward from the upper surface of the scale upper plate 225. The distance measurement sensor unit 210 including the depth measurement sensor unit 215 and the height measurement sensor unit 205 are disposed on the upper surface of the balance upper plate 225. When the depth measurement sensor unit 215 protrudes above the balance upper plate 225, Measure the distance.
도 5는 저울 상판에 안착된 피측정물의 중량 및 부피 측정이 완료된 이후 측정 상판에서 피측정물을 분리하는 예를 도시하고 있다. 저울 상판(225)에서 피측정물을 분리하면, 연결부재(230)의 내측에 인입되어 있던 엑츄에이터(220)가 원래 위치로 복원되며, 엑츄에이터(220)가 원래 위치로 복원하면 깊이 측정 센서부(215)는 저울 상판(225)의 하단으로 이동한다.Fig. 5 shows an example of separating the object to be measured from the measurement top plate after the measurement of the weight and the volume of the object to be measured placed on the scale top plate is completed. When the object to be measured is separated from the scale upper plate 225, the actuator 220 that has been drawn into the connecting member 230 is returned to its original position. When the actuator 220 is returned to its original position, 215 move to the lower end of the scale upper plate 225.
이와 같이 본 발명은 엑츄에이터의 이동에 따라 깊이 측정 센서부를 측정 상판의 표면 상단 또는 하단으로 이동시킨다.As described above, according to the present invention, the depth measurement sensor unit is moved to the upper or lower surface of the measurement top plate according to the movement of the actuator.
도 6은 본 발명의 일실시 예에 따른 좌우 거리 측정 센서부가 연장된(늘어난) 경우를 도시하고 있다. 이하 도 6을 이용하여 본 발명의 일실시 예에 따른 좌우 거리 측정 센서부가 연장된 경우에 대해 상세하게 알아보기로 한다.FIG. 6 shows a case where the left and right distance measurement sensor unit is extended (extended) according to an embodiment of the present invention. Hereinafter, a case in which the left and right distance measuring sensor unit according to the embodiment of the present invention is extended will be described in detail with reference to FIG.
도 6에 의하면, 좌우 거리 측정 센서부(210)는 좌측 거리 측정 센서부(210a)와 우측 거리 측정 센서부(210b)로 구성되며, 좌측 거리 측정 센서부(210a)와 우측 거리 측정 센서부(210b) 중 어느 하나의 센서부가 연장된다. 도 6에서는 좌측 거리 측정 센서부(210a)가 연장된 경우를 도시하고 있으나, 이에 한정되는 것은 아니다.6, the left and right distance measurement sensor unit 210 includes a left distance measurement sensor unit 210a and a right distance measurement sensor unit 210b. The left distance measurement sensor unit 210a and the right distance measurement sensor unit 210a 210b are extended. Although the left distance measuring sensor unit 210a is extended in FIG. 6, the present invention is not limited thereto.
부연하여 설명하면, 좌측 거리 측정 센서부(210a)가 연장된 상태에서 측정 시스템을 구성하는 센서부는 피측정물과의 거리를 측정한다. 물론 측정 시스템은 좌측 거리 측정 센서부(210a)가 연장된 경우, 좌측 거리 측정 센서부(210a)와 우측 거리 측정 센서부(210b) 사이의 거리를 저장하고 있으며, 이를 기반으로 측정 시스템은 피측정물의 좌우 거리를 산출한다.In other words, the sensor unit constituting the measurement system in the state in which the left distance measurement sensor unit 210a is extended measures the distance from the object to be measured. Of course, the measurement system stores the distance between the left distance measurement sensor part 210a and the right distance measurement sensor part 210b when the left distance measurement sensor part 210a is extended. Based on this, Calculate the left and right distance of water.
도 7은 본 발명의 일실시 예에 따른 좌측 거리 측정 센서부가 연장된 상태를 도시하고 있다. 이하 도 7을 이용하여 본 발명의 일실시 예에 따른 좌측 거리 측정 센서부가 연장된 상태를 상세하게 알아보기로 한다.FIG. 7 shows an extended state of the left distance measuring sensor according to an embodiment of the present invention. Hereinafter, a state in which the left distance measuring sensor unit is extended according to an embodiment of the present invention will be described in detail with reference to FIG.
도 7에 의하면, 측정 시스템은 좌측 거리 측정 센서부, 우측 거리 측정 센서부, 슬라이드 가이드, 로드셀, 베이스, 제1 위치 측정 센서 및 제2 위치 측정 센서를 포함한다. 물론 상술한 구성 이외에 다른 구성이 본 발명에서 제안하는 측정 시스템에 포함할 수 있다.According to Fig. 7, the measurement system includes a left distance measuring sensor, a right distance measuring sensor, a slide guide, a load cell, a base, a first position measuring sensor and a second position measuring sensor. Of course, other configurations than the above-described configuration may be included in the measurement system proposed by the present invention.
베이스(235)는 측정 시스템(200)의 저면에 위치한다. 베이스(235)는 일정 두께를 갖는 평판 형상으로 형성된다.The base 235 is located at the bottom of the measurement system 200. The base 235 is formed in a flat plate shape having a predetermined thickness.
로드셀(240)의 상단에는 저울 상판(225)이 위치한다. 저울 상판(225)은 평판 형태로 구성되며, 상단에 피측정물이 안착된다. 즉, 저울 상판(225)에 피측정물이 안착되면, 피측정물이 저울 상판(225)을 가압하며, 저울 상판(225)은 로드셀(240)을 가압한다. 로드셀(240)은 저울 상판(225)을 포함한 피측정물의 중량을 측정하며, 이후 기 저장된 저울 상판(225)의 중량을 차감하여 피측정물의 중량을 측정한다. 물론 로드셀(240)은 저울 상판(225)의 상단에 피측정물이 올려지기 전과 올려진 후의 중량 차이를 이용하여 피측정물의 중량을 측정할 수 있다.At the upper end of the load cell 240, the scale upper plate 225 is positioned. The balance upper plate 225 is formed in a flat plate shape, and the measured object is seated on the upper end. That is, when the measured object is placed on the scale upper plate 225, the measured object presses the scale upper plate 225, and the scale upper plate 225 presses the load cell 240. The load cell 240 measures the weight of the object to be measured including the balance upper plate 225, and then subtracts the weight of the previously stored balance upper plate 225 to measure the weight of the object to be measured. Of course, the load cell 240 can measure the weight of the object to be measured using the weight difference between before and after the object to be measured is placed on the upper end of the scale upper plate 225.
우측 거리 측정 센서부(210b)는 측정 시스템의 저울 상판(225)의 우측 상단에 위치하며, 피측정물과의 거리를 센싱한다. 좌측 거리 측정 센서부(210a)는 측정 시스템의 저울 상판(225)의 좌측 상단에 위치한다. 또한, 상술한 바와 같이 좌측 거리 측정 센서부(210a)는 측정 상판의 좌측 상단에서 좌측 방향으로 연장된다. 이를 위해 슬라이드 가이드(245)의 일측에 좌측 거리 측정 센서부(210a)가 고정된다.The right side distance measurement sensor unit 210b is located at the upper right of the balance upper plate 225 of the measurement system and senses the distance to the measured object. The left distance measurement sensor unit 210a is located at the upper left of the balance upper plate 225 of the measurement system. In addition, as described above, the left distance measurement sensor unit 210a extends leftward from the upper left of the measurement top plate. To this end, the left distance measuring sensor unit 210a is fixed to one side of the slide guide 245. [
슬라이드 가이드(245)는 상술한 바와 같이 일측에 좌측 거리 측정 센서부(210a)가 위치하며, 측정 시스템 내에서 좌측에서 우측으로, 우측에서 좌측으로 이동한다.The slide guide 245 moves from the left side to the right side and from the right side to the left side in the measurement system, with the left distance measurement sensor part 210a located on one side as described above.
제1 위치 측정 센서(250a)는 슬라이드 가이드(245)가 제1 위치에 위치하는지 여부를 센싱한다. 제1 위치는 슬라이드 가이드가 연장되지 않은 경우, 즉 좌측 거리 측정 센서부(210a)가 연장되지 않은 위치이다. The first position measuring sensor 250a senses whether the slide guide 245 is located at the first position. The first position is a position where the slide guide is not extended, that is, the left distance measurement sensor portion 210a is not extended.
제2 위치 측정 센서(250b)는 슬라이드 가이드(245)가 제2 위치에 위치하는지 여부를 센싱한다. 제2 위치는 슬라이드 가이드(245)가 연장된 경우, 즉 좌측 거리 측정 센서부(210a)가 연장된 위치이다.The second position measuring sensor 250b senses whether the slide guide 245 is located at the second position. The second position is a position where the slide guide 245 is extended, that is, the left distance measurement sensor portion 210a is extended.
측정 시스템은 제1 위치 측정 센서(250a) 또는 제2 위치 측정 센서(250b)로부터 전달받은 정보를 이용하여 좌측 거리 측정 센서부(210)의 연장 여부를 파악한다.The measurement system determines whether the left distance measurement sensor unit 210 is extended using the information received from the first position measurement sensor 250a or the second position measurement sensor 250b.
이와 같이 본 발명의 측정 시스템은 좌측 거리 측정 센서부를 연장함으로써 피측정물의 단면적이 작업대의 단면적보다 큰 경우에도 피측정물의 부피를 측정할 수 있다.As described above, the measurement system of the present invention can measure the volume of the object to be measured even when the cross-sectional area of the object to be measured is larger than the cross-sectional area of the workbench by extending the left distance-
이외에도 본 발명의 측정 시스템은 카메라를 추가로 포함될 수 있다. 일 예로 높이 측정 센서부 또는 연결부재에 카메라를 설치하며, 카메라는 측정 상판에 안착된 피측정물의 상부를 측정한다. 일 예로 카메라는 피측정물의 상부에 부착된 기표지를 촬영한다. 물론 본 발명의 측정 시스템은 높이 측정 센서부 또는 연결부재 이외에 다른 부위에 카메라를 설치할 수 있다.In addition, the measurement system of the present invention may further include a camera. For example, a camera is installed on a height measuring sensor unit or a connecting member, and the camera measures the top of the measured object placed on the measurement top plate. As an example, the camera photographs a marker mark attached to the upper part of the object to be measured. Of course, the measurement system of the present invention can install the camera in other areas than the height measurement sensor unit or the connection member.
