Description

Technical Field

[0001] The embodiments of this invention relate to the field of plastering construction technology, specifically to: 1) plastering construction process and system for building engineering using three-dimensional optical scanning technology; 2) a method, equipment and computer-readable storage medium for generating control target information for plastering in building engineering; and 3) a method and equipment for locating control target calibration components for plastering in building engineering. Background Technology

[0002] Plastering in construction is a traditional decorative technique involving the application of mortar to the surfaces of walls, ceilings, and other structures. For plastering already constructed walls, the traditional method is the "targeting and screeding" technique. "Targeting" involves creating standard mortar spots before plastering. Based on the required plaster thickness, a standard mortar spot is made above each corner of the wall, and additional spots are made at window sills and corners using a plumb line. Then, a standard mortar spot is made at the lower corner of the wall using a plumb line. "Screeding" is also a crucial step in ensuring plaster quality. A mortar strip is created between the upper and lower mortar spots, with the same height as the spots and sloping sides. This serves as an important control marker for large-area plastering. However, because the flatness of the constructed walls is often uneven, and there are protrusions, and because targeting and screeding relies heavily on human experience which is prone to significant errors, the flatness and verticality of the wall surface after plastering using this method are often less than ideal.

[0054] For plastering already constructed walls, the traditional method is screeding. However, the flatness of the wall surface is often uneven, and there are protrusions. Furthermore, screeding relies heavily on human experience, which is prone to significant errors. Therefore, the flatness and verticality of the wall surface after screeding are not ideal. To address these issues, a plastering construction process and system utilizing three-dimensional optical scanning technology is provided.

[0055] Figure 1 This is a schematic diagram illustrating the principle of a building plastering construction system utilizing three-dimensional optical scanning technology, according to an embodiment of the present invention. Figure 1 As shown, the building plastering construction system using three-dimensional optical scanning technology specifically includes: a three-dimensional optical scanning device 1, a computer modeling device 2, a building plastering control target point information generation device 3, a building plastering control target point calibration component positioning device 4, a plastering control target point positioning device 5, and a plastering control target point calibration component cutting device 6.

[0056] The three-dimensional optical scanning device 1 is used to obtain a measured model of the wall surface that has been built and is to be plastered. In a preferred embodiment, the three-dimensional optical scanning device 1 is a three-dimensional laser scanner; in this case, the measured model may include a fitted surface obtained from the point cloud data of the wall surface to be plastered acquired by the three-dimensional laser scanning. Three-dimensional laser scanning technology is a scanning technology that integrates computer technology, optoelectronic technology, and precision mechanical manufacturing and processing. It can quickly determine the shape, size, and spatial position of a target from complex entities or real scenes, and form high-density point cloud data of the target surface. After scanning, the point cloud data and image data can be mapped through texture to generate a high-precision three-dimensional model (measured model). Its ranging accuracy is at the millimeter level, its angle measurement accuracy is at the second level, and its point accuracy is at the millimeter level. Generally, a panoramic scan can be completed in just a few seconds, thus having the advantages of accurate measurement and high efficiency.

[0057] Computer modeling device 2 is used to obtain the design model corresponding to the masonry wall to be plastered. Typically, the computer modeling is performed using computer-aided design (CAD) software. Many commercially available CAD software programs are available; commercially available or self-developed CAD software can be used and installed on the computer hardware system to establish computer modeling device 2.

[0058] The building plastering control target information generation device 3 is used to acquire the measured model and the design model, and compare and analyze the measured model and the design model to generate plastering control target information. The plastering control target information includes plastering control target positioning information and plastering control target calibration component thickness information. The plastering control target positioning information is used to determine the specific position of the plastering control target calibration component installed on the masonry wall to be plastered. The plastering control target calibration component thickness information is used to determine the corresponding thickness of the plastering control target calibration component. When plastering the masonry wall to be plastered, the thickness of the plastering control target calibration component protruding from the masonry wall to be plastered is used as a benchmark to control the plastering thickness around the plastering control target calibration component.

[0059] Generally, a building plastering control target information generation device 3 includes at least a processor coupled to a memory. The memory stores computer programs or instructions, and the processor executes the computer program or instructions in the memory, causing the building plastering control target information generation device to perform the following building plastering control target information generation method. This method includes at least: acquiring a measured model of a masonry wall to be plastered obtained through three-dimensional optical scanning; acquiring a design model corresponding to the masonry wall to be plastered obtained through computer modeling; and comparing and analyzing the measured model and the design model to generate plastering control target information.

[0060] The internal algorithm of the plastering control target information generation device 3 is specifically used to generate plastering control target information. It is designed based on the principle that the thickness distribution of the plaster layer formed by plastering construction based on the plastering control target information can better compensate for the error distribution between the actual masonry wall to be plastered and the designed masonry wall to be plastered, so that the actual plastered wall surface is closer to the designed plastered wall surface.

[0061] In one specific embodiment of the present invention, when determining the positioning information of plastering control target points, the basic principle is to ensure that the plastering control target points are evenly distributed on the already constructed wall surface to be plastered. When determining the thickness information of the plastering control target point calibration components, the flatness, verticality, room span and depth dimensions, and the minimum designed plastering thickness parameters of the already constructed wall surface to be plastered are all used as control conditions. This forms the basic principle of compensating for the flatness and verticality errors of the already constructed wall surface to be plastered as much as possible while ensuring the room span and depth dimensions and the minimum designed plastering thickness. For wall protrusions, the above basic principle is a prerequisite. When the existence of a wall protrusion makes it difficult to meet this prerequisite, the wall protrusion is removed. In this case, the plastering control target point information generation device 3 can generate indication information of the range of protrusions to be removed, which is used to indicate to the operator the wall protrusions that need to be removed.

[0062] The building plastering control target point calibration device 4 is used to acquire the plastering control target point information and the real-time position information of the plastering control target point positioning device 5, and compare the real-time position information with the plastering control target point positioning information. Then, based on the comparison result, it is determined whether the real-time position of the plastering control target point positioning device 5 meets the requirements of the plastering control target point positioning information. When it is determined that the real-time position of the plastering control target point positioning device meets the requirements of the plastering control target point positioning information, a plastering control target point positioning device positioning success notification is generated and provided to the operator. When it is determined that the real-time position of the plastering control target point positioning device does not meet the requirements of the plastering control target point positioning information, a plastering control target point positioning device movement indication notification is generated and provided to the operator.

[0063] Generally, a plastering control target point positioning device 4 typically includes at least a processor coupled to a memory. The memory stores computer programs or instructions, and the processor executes these programs or instructions to cause the plastering control target point positioning device 4 to perform the following plastering control target point positioning method. This method includes at least: acquiring plastering control target point information; acquiring real-time position information of the plastering control target point positioning device 5; comparing the real-time position information with the plastering control target point positioning information, and determining, based on the comparison result, whether the real-time position of the plastering control target point positioning device 5 meets the requirements of the plastering control target point positioning information; generating and providing a successful positioning notification to the operator when the real-time position of the plastering control target point positioning device meets the requirements of the plastering control target point positioning information; and generating and providing a movement indication notification to the operator when the real-time position of the plastering control target point positioning device does not meet the requirements of the plastering control target point positioning information.

[0064] The plastering control target positioning device 5 is a handheld device that can be movably attached to the wall surface to be plastered. It includes a target position auxiliary marking section for marking the specific installation position of the plastering control target calibration component on the wall surface, a first measuring section for measuring the horizontal position of the auxiliary marking section on the wall surface, and a second measuring section for measuring the vertical position of the auxiliary marking section on the wall surface. The real-time position information is the real-time measurement result of the first measuring section and the real-time measurement result of the second measuring section. In a preferred embodiment, the plastering control target positioning device 5 is integrated with the building plastering control target calibration component positioning device 4, in which case the building plastering control target calibration component positioning device 4 is integrated into the handheld device.

[0065] The plaster control target calibration part cutting device 6 is used to acquire a cutting command, which includes a cutting length set according to the thickness information of the plaster control target calibration part. The plaster control target calibration part cutting device 6 is also used to cut the bar material to be cut according to the cutting length to obtain the plaster control target calibration part. The specific structure of the plaster control target calibration part cutting device 6 is easily implemented. For example, the plaster control target calibration part cutting device 6 can include three parts: a feeding mechanism, a cutting length control mechanism, and a cutting mechanism. The feeding mechanism is used to transport the bar material to be cut to the cutting mechanism, the cutting mechanism is used to cut the bar material, and the cutting length control mechanism is used to control the relative position between the bar material to be cut and the cutting mechanism so that the cut plaster control target calibration part meets the required thickness (i.e., the axial length of the plaster control target calibration part).

[0066] In a preferred embodiment, the cutting command should be issued by the plastering control target point positioning device 4. This allows the positioning device 4 to send a cutting command to the plastering control target point cutting device during the positioning process, ensuring that the currently positioned plastering control target point corresponds to the plastering control target point cutting device 6, effectively preventing confusion between different plastering control target point points. Correspondingly, the positioning device 4 should also be equipped with the function of issuing a cutting command to the plastering control target point cutting device 6 after acquiring plastering control target point information.

[0067] Figure 2 This is a schematic diagram illustrating a plastering construction process for building engineering using three-dimensional optical scanning technology, according to an embodiment of the present invention. Figure 2 As shown, the plastering construction process using 3D optical scanning technology employed... Figure 1 The illustrated building plastering construction system utilizes three-dimensional optical scanning technology and includes the following specific steps.

[0068] Step S101: Obtain a measured model of the constructed wall to be plastered through three-dimensional optical scanning, and obtain a design model corresponding to the constructed wall to be plastered through computer modeling. This step requires the use of three-dimensional optical scanning equipment 1 and computer modeling equipment 2.

[0069] Step S102: The measured model and the design model are compared and analyzed using the building engineering plastering control target point information generation device 3 to generate plastering control target point information. The plastering control target point information includes plastering control target point positioning information and plastering control target point calibration component thickness information.

[0070] Step S103: After the plastering control target information generation device 3 generates the plastering control target information, it displays a measured model of the masonry wall to be plastered, containing the plastering control target information, on its display screen. The measured model of the masonry wall to be plastered contains plastering control target location indication information. Furthermore, the measured model of the masonry wall to be plastered also contains a wall protrusion distribution diagram, which includes indication information of the area of ​​protrusions that need to be removed.

[0071] Step S104: According to the indication information of the area to be removed, the protrusions to be removed on the masonry wall to be plastered are removed.

[0072] Step S105: Provide the plastering control target point information to the plastering control target point calibration device 4, and then implement the plastering control target point calibration device positioning method. During this process, after the plastering control target point calibration device 4 provides the operator with a notification of successful positioning of the plastering control target point, the target point position auxiliary marking part is used to mark the already constructed wall to be plastered (e.g., drawing lines on the already constructed wall to be plastered). After the plastering control target point calibration device 4 provides the operator with a notification of movement of the plastering control target point, the handheld device is moved on the already constructed wall to be plastered according to the notification of movement of the plastering control target point. (See...) Figure 9 As shown), until the plastering control target point calibration device 4 provides the operator with a notification that the plastering control target point positioning device has been successfully positioned.

[0073] Step S106: A cutting command is sent to the plastering control target calibration component cutting device 6 via the plastering control target calibration component positioning device 4. The cutting command includes a cutting length set according to the thickness information of the plastering control target calibration component.

[0074] Step S107: The plastering control target calibration part cutting device 6 cuts the bar material to be cut according to the cutting length to obtain the plastering control target calibration part.

[0075] Step S108: Install the plastering control target point calibration component according to the marks made on the masonry wall to be plastered using the target point position auxiliary marking part (e.g., by adhesive installation, see [link]). Figure 11 (As shown) at the corresponding position on the already constructed wall surface to be plastered.

[0076] Step S109: Plastering is carried out on the masonry wall to be plastered. During the plastering, the thickness of the plastering control target point protruding from the masonry wall to be plastered is used as a benchmark to control the plastering thickness around the plastering control target point.

[0077] Because the plastering control target information generation device 3 compares and analyzes the measured model of the masonry wall to be plastered obtained by three-dimensional optical scanning with the design model corresponding to the masonry wall to be plastered obtained by computer modeling to generate plastering control target information, the thickness distribution of the plaster layer formed by subsequent plastering construction based on the plastering control target information can better compensate for the error distribution between the actual masonry wall to be plastered and the designed masonry wall to be plastered, which helps to make the actual plastered wall surface more closely resemble the designed plastered wall surface.

[0078] The following section will further explain the details and improvements of the above-mentioned plastering construction system using 3D optical scanning technology, the plastering construction process using 3D optical scanning technology, and the equipment and steps involved.

[0079] Figure 3 This is a schematic diagram illustrating the principle of a plastering control target point information generation device for building engineering, according to an embodiment of the present invention. Figure 3 As shown, the building plastering control target point information generation device 3 includes a processor 31, a memory 32, an input device 33, an output device 34, and a communication device 35.

[0080] The processor 31 may include a central processing unit (CPU), a digital signal processor (DSP), a microprocessor, an application-specific integrated circuit (ASIC), a microcontroller (MCU), a field-programmable gate array (FPGA), or one or more integrated circuits for implementing logic operations. The processor 31 can be used to implement the required functions for the building plastering control target information generation device 3, such as controlling the entire building plastering control target information generation device 3, executing software programs, and processing data from the software programs. The software may be software used to implement the building plastering control target information generation method of this embodiment of the invention.

[0081] Memory 32 may include mass storage for data or instructions. For example, and not limitingly, memory 32 may include a hard disk drive (HDD), floppy disk drive, flash memory, optical disk, magneto-optical disk, magnetic tape, or Universal Serial Bus (USB) drive, or a combination of two or more of these. Where appropriate, memory 32 may include removable or non-removable (or fixed) media. Where appropriate, memory 32 may be internal or external to processor 31. In a particular embodiment, memory 32 is non-volatile solid-state memory. In a particular embodiment, memory 32 includes read-only memory (ROM); where appropriate, the ROM may be a mask-programmed ROM, a programmable ROM (PROM), an erasable PROM (EPROM), an electrically erasable PROM (EEPROM), an electrically rewritable ROM (EAROM), or flash memory, or a combination of two or more of these.

[0082] Input device 33 communicates with processor 31 and can accept user input in various ways. For example, input device 31 can be a mouse, keyboard, touch screen device, or sensor. Output device 34 communicates with processor 31 and can display information in various ways. For example, output device 34 can be various displays, such as liquid crystal displays, light-emitting diode displays, cathode ray tube displays, or projectors.

[0083] The communication device 35 can be used to support communication between the building plastering control target information generation device 3 and the three-dimensional optical scanning device 1, the computer modeling device 2 and the building plastering control target calibration device 4, respectively. These communications can be wireless communication, wired communication or communication through a portable data storage medium (such as a portable hard drive, SD card, USB memory, etc.).

[0084] Figure 4 This is a flowchart illustrating a method for generating control target information for plastering in building construction, according to an embodiment of the present invention. Figure 4 The method for generating control target point information for plastering in building engineering shown is based on Figure 3 The device shown is for generating target point information for plastering control in building construction. For example... Figure 4 As shown, the method for generating plastering control target point information in building engineering includes, in addition to acquiring a measured model of the masonry wall to be plastered obtained through three-dimensional optical scanning, acquiring a design model corresponding to the masonry wall to be plastered obtained through computer modeling, and comparing and analyzing the measured model and the design model to generate plastering control target point information, it can also display a measured model diagram of the masonry wall to be plastered containing the plastering control target point information on a display after generating the plastering control target point information (see...). Figure 8As shown, the measured model of the wall surface to be plastered contains indication information of the plastering control target point positions. Furthermore, the measured model of the wall surface to be plastered also contains a distribution map of wall protrusions, which includes indication information of the area of ​​protrusions to be removed. Since wall protrusions are often distributed on the wall surface to be plastered, when the processor 31 compares and analyzes the measured model with the design model to generate plastering control target point information, some wall protrusions may constitute interference factors for the comparison analysis algorithm. By generating the area of ​​protrusions to be removed on the wall protrusion distribution map, and then manually removing the corresponding wall protrusions according to the area of ​​protrusions to be removed, it helps to further improve the quality of plastering construction.

[0085] After generating the plastering control target information, the plastering control target information can also be stored as a corresponding computer-readable file. This computer-readable file can be stored on a removable data storage medium (such as a mobile hard drive, SD card, USB memory, etc.) through the communication device 35, and then transferred to the building engineering plastering control target calibration positioning device 4 through the removable data storage medium.

[0086] Figure 5 This is a schematic diagram illustrating the principle of a positioning device for a plastering control target point calibration component in building engineering, according to an embodiment of the present invention. Figure 5 As shown, the plastering control target point positioning device 4 is a handheld device that can be movably attached to the wall surface to be plastered. It specifically includes a processor 41, a memory 42, an input device 43, an output device 44, a communication device 45, a target point position auxiliary marking unit 46, a first measuring unit 47, and a second measuring unit 48.

[0087] The processor 41 may include a central processing unit (CPU), a digital signal processor (DSP), a microprocessor, an application-specific integrated circuit (ASIC), a microcontroller (MCU), a field-programmable gate array (FPGA), or one or more integrated circuits for implementing logic operations. The processor 41 can be used to implement the required functions for the plastering control target calibration device 4, such as controlling the entire plastering control target calibration device 4, executing software programs, and processing data from the software programs. The software may be software used to implement the plastering control target calibration device positioning method of this embodiment of the invention.

[0088] Memory 42 may include mass storage for data or instructions. For example, and not limitingly, memory 42 may include a hard disk drive (HDD), floppy disk drive, flash memory, optical disk, magneto-optical disk, magnetic tape, or Universal Serial Bus (USB) drive, or a combination of two or more of these. Where appropriate, memory 42 may include removable or non-removable (or fixed) media. Where appropriate, memory 42 may be internal or external to processor 41. In a particular embodiment, memory 42 is non-volatile solid-state memory. In a particular embodiment, memory 42 includes read-only memory (ROM); where appropriate, the ROM may be a mask-programmed ROM, a programmable ROM (PROM), an erasable PROM (EPROM), an electrically erasable PROM (EEPROM), an electrically rewritable ROM (EAROM), or flash memory, or a combination of two or more of these.

[0089] Input device 43 communicates with processor 41 and can accept user input in various ways. For example, input device 41 can be a mouse, keyboard, touch screen device, or sensor. Output device 44 communicates with processor 41 and can display information in various ways. For example, output device 44 can be various displays, such as liquid crystal displays, light-emitting diode displays, cathode ray tube displays, or projectors.

[0090] The communication device 45 can be used to support communication between the building plastering control target calibration part positioning device 4 and the building plastering control target information generation device 3 and the plastering control target calibration part cutting device 6, respectively. This communication can be wireless communication, wired communication or communication through a portable data storage medium (such as a portable hard drive, SD card, USB memory, etc.).

[0091] The target position auxiliary marking unit 46 is used to assist in marking the specific installation position of the plaster control target point calibration component on the wall surface to be plastered. Specifically, it is a position indicator mark set on the housing of the handheld device. This position indicator mark is used for manual drawing on the wall surface to be plastered.

[0092] The first measuring unit 47 is used to measure the horizontal position of the target position auxiliary marking unit 46 on the wall surface to be plastered. Specifically, a horizontal infrared rangefinder is used. The relative position between the horizontal infrared rangefinder and the target position auxiliary marking unit 46 is fixed. When in use, the wall surface at the corner of the wall surface to be plastered (or a baffle is placed artificially if there is no wall surface) is used as the reference plane. The horizontal distance between the horizontal infrared rangefinder and the wall surface is measured by the horizontal infrared rangefinder, thereby obtaining the horizontal position of the target position auxiliary marking unit 46 on the wall surface to be plastered.

[0093] The second measuring unit 48 is used to measure the vertical position of the target position auxiliary marking unit 46 on the wall surface to be plastered. Specifically, a vertical infrared rangefinder is used. The relative position between the vertical infrared rangefinder and the target position auxiliary marking unit 46 is fixed. When in use, the top or bottom plate adjacent to the wall surface to be plastered is used as the reference plane. The vertical distance between the vertical infrared rangefinder and the reference plane is measured by the vertical infrared rangefinder, thereby obtaining the vertical position of the target position auxiliary marking unit 46 on the wall surface to be plastered.

[0094] The first measuring unit 47 and the second measuring unit 48 communicate with the processor 41 so that the processor 41 can compare the real-time position information with the plastering control target point positioning information, and determine whether the real-time position of the building engineering plastering control target point calibration device 4 meets the requirements of the plastering control target point positioning information based on the comparison result.

[0095] visible, Figure 5 The positioning device 4 for plastering control target point calibration of the building project shown has integrated the plastering control target point positioning device 5.

[0096] Figure 6 This is a flowchart illustrating a method for locating target calibration components for plaster control in building construction, according to an embodiment of the present invention. Figure 6 The method for locating control target points for plastering in building construction shown is based on Figure 5 The image shows a positioning device for the target point calibration component in a building plastering control project. For example... Figure 6 As shown, the positioning method for plastering control target point calibration components in building construction includes:

[0097] Step S201: Display a target plastering control target filter on the display (belonging to output device 44) for selecting a target plastering control target from multiple plastering control target points. After the target plastering control target filter is operated by input device 43 to filter out the target plastering control target point, the plastering control target point positioning information and plastering control target point calibration component thickness information corresponding to the target plastering control target point are used as the plastering control target point information.

[0098] Since multiple plastering control target point calibration pieces are often required on the already constructed walls to be plastered, and since a three-dimensional optical scan can scan all the already constructed walls to be plastered in a room (usually four) at a time, the plastering control target point information generated by the building engineering plastering control target point information generation device 3 often contains the positioning information of each plastering control target point and the thickness information of the plastering control target point calibration pieces. Therefore, in step S201, the target plastering control target point is first selected using the target plastering control target point filter software, so that the specific plastering control target point calibration pieces can be cut and positioned subsequently.

[0099] Step S202: Obtain the real-time location information of the plastering control target point (specifically, the plastering control target point information refers to the positioning information of the plastering control target point corresponding to the target plastering control target point and the thickness information of the plastering control target point calibration component) and the plastering control target point positioning device (the plastering control target point positioning device is the building engineering plastering control target point calibration component positioning equipment 4).

[0100] Step S203: Compare the real-time location information with the plastering control target point positioning information, and determine whether the real-time position of the plastering control target point positioning device meets the requirements of the plastering control target point positioning information based on the comparison result. When it is determined that the real-time position of the plastering control target point positioning device meets the requirements of the plastering control target point positioning information, generate and provide the operator with a plastering control target point positioning device positioning success notification. When it is determined that the real-time position of the plastering control target point positioning device does not meet the requirements of the plastering control target point positioning information, generate and provide the operator with a plastering control target point positioning device movement indication notification.

[0101] In step S203, to facilitate the operator's operation, the display (belonging to the output device 44) displays a first display message as a notification of successful positioning of the plastering control target positioning device and a second display message as a notification of movement indication of the plastering control target positioning device.

[0102] The second display information may include a first arrow indicating the horizontal direction in which the plastering control target positioning device will be moved on the wall surface to be plastered; a first numerical value indicating the distance to be moved along the direction of the first arrow on the wall surface to be plastered; a second arrow indicating the vertical direction in which the plastering control target positioning device will be moved on the wall surface to be plastered; and a second numerical value indicating the distance to be moved along the direction of the second arrow on the wall surface to be plastered. This provides the operator with a clear and intuitive indication of the movement of the plastering control target positioning device.

[0103] In addition, after the first display information, which serves as a notification of successful positioning of the plastering control target positioning device, is displayed on the screen, a cutting start switch can be generated or activated on the screen. By responding to the operator's operation of the cutting start switch using the input device 43, a cutting command can be sent to the plastering control target calibration component cutting device 6.

[0104] In one alternative embodiment, the plastering control target point calibration component cutting device 6 is designed as a rectangular box structure (see...). Figure 10 As shown), its top surface is provided with an insertion port for the bar to be cut. The bar to be cut can be made of a material such as plastic that is easy to cut and has a certain strength to maintain its shape. The diameter of the bar to be cut is just large enough to be inserted into the insertion port. Figure 10 The white, elongated object on the plastering control target calibration component cutting device 6 is the bar to be cut. A pre-cut bar (i.e., plastering control target calibration component) outlet is located on one side of the rectangular box structure, used to discharge the plastering control target calibration component cut from the bar to be cut from the rectangular box structure. The feeding mechanism is located within the rectangular box structure, specifically employing a piston-type reciprocating motion mechanism to support the lower end of the bar to be cut. The position of the piston rod of the piston-type reciprocating motion mechanism is controlled by the cutting length control mechanism. When the piston rod of the piston-type reciprocating motion mechanism moves downward, the bar to be cut moves axially downward along the insertion port of the bar to be cut. The cutting mechanism uses a saw blade, the direction of which is perpendicular to the bar to be cut. When the bar to be cut moves downward to the set position, the saw blade can cut into the bar to be cut, at which point the plastering control target calibration component will fall out from the outlet.

[0105] The foregoing has described the relevant content of this application. Those skilled in the art will be able to implement this application based on these descriptions. All other embodiments obtained by those skilled in the art based on the foregoing content of this specification without inventive effort should fall within the scope of this application.
