Description

Technical Field

[0001] The invention relates to the technical field of bottom plate steel bar binding, and specifically designs a bottom plate steel bar binding auxiliary monitoring method, device and medium based on pad block marking. Background Art

[0002] Rebar binding is a very important task in the construction process. Better binding of steel bars can enhance the tensile strength of concrete, prevent concrete cracking, improve the durability of buildings and ensure the safety of buildings.

[0003] In the related art, before tying the steel bars, the main bars are placed in columns according to the markings, and then the distribution bars are placed in rows. In addition, in order to facilitate the tying of the steel bars, pads are usually placed according to the marking positions before the steel bars are placed, and the pads support the steel bars. At present, pads have various shapes, and ordinary pads are more common. Ordinary pads include square or rectangular pads. Ordinary pads do not have the function of fixing the steel bars. During the process of workers tying the steel bars, if there are unexpected situations such as improper operation, it is easy for the steel bars to slide on the ordinary pads, thereby causing the positions of the main bars and the distribution bars to be offset, and the steel bar binding structure is not firm, resulting in reduced durability and reduced safety of the building. Summary of the invention

[0004] The purpose of the present invention is to provide a method, device and medium for auxiliary monitoring of bottom plate steel bar binding based on pad block identification. The method mainly detects the steel bar end faces and pad block surfaces through cameras fixedly arranged on both sides of the bottom plate steel bars. The pad block identification corresponding to the steel bar end faces can be obtained through the detection, thereby judging whether the pad block identification is offset. When an offset occurs, the offset pad position can be obtained and a steel bar offset warning can be issued to remind workers that the steel bars at the current pad block position are offset, thereby avoiding a loose steel bar binding structure.

[0005] In order to solve the above technical problems, the present invention adopts the following solutions:

[0006] A bottom plate steel bar binding auxiliary monitoring method based on pad marking, wherein the bottom plate steel bar is composed of a plurality of vertical steel bars arranged in sequence in columns and a plurality of horizontal steel bars arranged in sequence in rows, and each column and each row is provided with at least one pad located below the staggered position of the vertical steel bars and the horizontal steel bars, and cameras for photographing the end faces of multiple rows and columns of steel bars and the pads are fixedly provided on adjacent two sides of the bottom plate steel bars, and a sound sensor is provided at the camera;

[0007] The method comprises the following steps:

[0008] S0. Before the bottom plate reinforcement is tied, obtain the current reference image captured by the current camera;

[0009] S1. During the process of binding the bottom plate steel bars, the sound generated by the steel bar binding is detected by a sound sensor. When the sound sensor detects a sound signal exceeding a preset threshold, the current time point is recorded;

[0010] S2, extracting the current video stream shot by the camera at the current time point, and performing key frame sampling processing on the extracted current video stream to obtain multiple pictures to be identified arranged in time order;

[0011] S3. The image to be identified and the current reference image are processed in columns according to the order of the pad position captured by the camera, and the pads under the end faces of the steel bars in each column are marked with positioning lines. According to the positioning lines, it is determined in turn whether the position of the current end face of the steel bar on the pad in the image to be identified is consistent with that in the reference image. If not, the position of the pad that has been offset is obtained and a steel bar offset warning is issued.

[0012] Furthermore, S3 specifically includes the following steps:

[0013] S31: performing image column processing on the image to be identified and the current reference image according to the position sequence of the pad blocks captured by the camera, to obtain a plurality of image column data to be identified and a plurality of reference image column data;

[0014] S32: matching the to-be-recognized picture column data with the reference picture column data according to the block position sequence of the blocks in the to-be-recognized picture column data and the block position sequence of the blocks in the reference picture column data;

[0015] S33: marking the pads below the end faces of the steel bars in the mutually matching to-be-identified image column data and the reference image column data according to the pad position sequence, and obtaining the positioning lines on the pad surfaces on the to-be-identified image column data and the reference image column data respectively;

[0016] S34: Judge the pictures to be identified in turn to determine whether the positioning line on the pad surface in the picture column data to be identified is consistent with the positioning line on the pad surface in the matching reference picture column data; if not, obtain the offset pad position and issue a steel bar offset warning.

[0017] Furthermore, in S31, the image segmentation process is specifically as follows:

[0018] First, target image recognition is performed on the pads in the image to be identified and the reference image. When the pads are identified, the image to be identified and the reference image are cut with the identification frame where the pads are located, and multiple column data of the image to be identified and multiple column data of the reference image are generated respectively. The multiple column data of the image to be identified and the multiple column data of the reference image are numbered respectively according to the order of the pad positions.

[0019] Further, in S33, the process of marking the positioning line is specifically as follows:

[0020] Draw a vertical line downward on the pad according to the circular feature point corresponding to the end face of the steel bar, and mark the surface of the pad with the vertical line to form a positioning line on the surface of the pad.

[0021] Furthermore, the characteristic points of the circle corresponding to the end face of the steel bar include the center point of the circle and the circumscribed point of the circle;

[0022] When a vertical line is drawn downward from the center point of the circle to the pad, the positioning line on the current pad surface passes vertically through the center point of the circle;

[0023] When a vertical line is drawn downward to the pad with the circular circumference point, the circular circumference point is located on the horizontal line passing through the center point of the circle, and the positioning line on the surface of the current pad passes vertically through the circular circumference point.

[0024] Furthermore, in S2, the process of extracting the current video stream captured by the camera at the current time point is specifically as follows: the current time point is pushed forward and backward for a period of time in the monitoring video captured by the camera to mark the time point, and then the video stream of the monitoring video is intercepted at the marked time point to obtain the current video stream.

[0025] Furthermore, in S2, the process of performing key frame sampling processing on the extracted current video stream is specifically as follows: based on the similarity between the video frames in the current video stream and the current reference picture, video frames whose similarity is within a predetermined range are extracted from the current video stream as key frames.

[0026] Furthermore, the pad is a square or rectangular pad, and the pad is arranged on the template to isolate the bottom plate steel bars and the template.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] The relative arrangement of components and steps, the numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention unless specifically stated otherwise.

[0040] At the same time, it should be understood that for the convenience of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship.

[0041] Additionally, descriptions of well-known structures, functions, and configurations may be omitted for clarity and conciseness.One of ordinary skill in the art will recognize that various changes and modifications may be made to the examples described herein without departing from the spirit and scope of the present disclosure.

[0042] Technologies, methods, and apparatus known to ordinary technicians in the relevant field may not be discussed in detail, but where appropriate, such technologies, methods, and apparatus should be considered part of the authorization specification.

[0043] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0044] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments:

[0045] Example 1

[0046] In this embodiment, the steel bar binding process mainly refers to the binding of the bottom plate steel bars. The bottom plate steel bars are steel bar structures laid on the template, which are composed of vertical steel bars and horizontal steel bars. Specifically, according to the lines on the template, pads can be placed at preset positions first, and then the vertical steel bars (i.e. main bars) are placed in columns, and then the horizontal steel bars (i.e. distribution bars) are placed in rows, thereby forming the bottom plate steel bars, and then the steel bars are bound at the staggered positions of the vertical and horizontal steel bars on the bottom plate steel bars.

[0047] In the actual rebar binding process, since the rebar itself has a certain weight and is not easy to shift, in order to save production costs, it is more common to use ordinary pads in the actual rebar binding process. The ordinary pads are mainly square or rectangular pads. The rebars can be supported by the ordinary pads, which is convenient for binding and plays an isolation role between the rebars and the template. However, the ordinary pads cannot fix the rebars. If improper operation or other unexpected situations occur during the rebar binding process, it is easy to collide with the rebars and cause the rebars to slide on the ordinary pads, resulting in the displacement of the rebars. It may also cause the rebars to fall, making the rebar binding structure unstable, resulting in reduced durability and reduced safety of the building.

[0048] Furthermore, since the steel bars themselves have a certain weight, it can be known that during the actual steel bar binding process, the collision force that causes the steel bars to shift or fall is relatively large, and a large collision force will inevitably cause a loud noise.

[0049] Therefore, the present invention takes the above situation into consideration and proposes an auxiliary monitoring method for steel bar binding using ordinary pads. A sound sensor is arranged on one side of the bottom plate steel bars, and the sound sensor is used to detect the sound of the steel bar binding process. A preset threshold is set in advance. When the sound sensor detects a sound signal exceeding the preset threshold, it indicates that a loud noise has been generated in the current steel bar binding process. At this time, the workers are assisted to judge whether the steel bars are offset. The position of the offset steel bars can be obtained quickly and accurately, thereby performing subsequent correction work on the steel bar offset to avoid an unstable steel bar binding structure.

[0050] In order to assist workers in determining whether the steel bars are offset, the present invention chooses to set cameras on both adjacent sides of the bottom plate steel bars. Since the cross-section of the steel bar structure of the bottom plate steel bars in the horizontal direction is a square or rectangular, and the left and right sides of the steel bar structure of the bottom plate steel bars are the end faces of the same horizontal steel bars, and the upper and lower sides of the steel bar structure of the bottom plate steel bars are the end faces of the same vertical steel bars, in order to achieve effective detection, at least cameras need to be set on both adjacent sides of the bottom plate steel bars. At the same time, one camera can detect the end faces of the horizontal steel bars on the same side, and the other camera can detect the end faces of the vertical steel bars on the same side, thereby satisfying the monitoring of all the steel bars constituting the bottom plate steel bars.

[0051] Among them, there is currently a technical means of using a camera to detect whether the steel bars are offset during the steel bar binding process. However, this technical means usually uses a drone to shoot the horizontal plane of the bottom plate steel bars from top to bottom, and then determines whether the intersection between the vertical steel bars and the horizontal steel bars is offset based on image recognition. The steel bar placement scene is relatively complicated. If a drone is used to shoot the horizontal plane of the bottom plate steel bars from top to bottom, it is easy to cause the intersection between the vertical steel bars and the horizontal steel bars to be unclear. In addition, it is difficult to control the shooting angle of the drone, and it is easy for the shooting angle to not be level with the horizontal plane of the bottom plate steel bars. It is difficult to determine whether the intersection between the vertical steel bars and the horizontal steel bars in the current shooting picture is located at the preset position in the template.

[0052] Therefore, the present invention selects to fix a camera on the side of the bottom plate steel bar, and uses the camera to shoot the pad surface and the steel bar end face at a horizontal angle, such as Figure 2 As shown, the current camera captures the end face of the vertical steel bar and the surface of the pad below the vertical steel bar, making it easy to accurately locate and mark the position of the steel bar end face on the pad through the camera shooting picture.

[0053] Furthermore, the present invention determines that the end face of the steel bar photographed by the camera is positioned and marked on the surface of the pad block, and takes the surface of the pad block as a basis, which is equivalent to using the side length of the surface of the pad block as a ruler. In each captured image, the current position of the end face of the steel bar is calculated by the ruler, thereby determining whether the steel bar corresponding to the current end face of the steel bar is offset. In order to realize the ruler function of the pad block, the present invention requires that at least one pad block located below the staggered position of the vertical and horizontal steel bars be provided in each column and row when presetting the pad block position. The purpose is that when the camera photographs one side of the bottom plate steel bars, pad blocks are provided below all vertical steel bar end faces or all horizontal steel bar end faces on this side.

[0054] In one embodiment, if Figure 3 As shown, the bottom plate reinforcement is composed of five vertical reinforcements arranged in columns and seven horizontal reinforcements arranged in rows, and the first camera and the second camera are arranged at a horizontal angle on the top and right of the bottom plate reinforcement, respectively. At this time, the first camera can simultaneously capture the end faces of the five vertical reinforcements and the surface of the pad under the five vertical reinforcements, and the second camera can simultaneously capture the end faces of the seven horizontal reinforcements and the surface of the pad under the seven horizontal reinforcements. In order to ensure that the end faces of the reinforcements and the surface of the pad captured by the first camera and the second camera are clear and the positional relationship between the two is accurate, the pad is pre-set at the peripheral measuring point. The peripheral measuring point is the staggered point between the vertical reinforcement and the horizontal reinforcement outside the bottom plate reinforcement. The judgment accuracy can be improved based on whether the reinforcement is offset by the peripheral measuring point. Among them, the pad located on the inner side of the bottom plate reinforcement can be set by considering the distance difference between the stress point of the bottom plate reinforcement and the reinforcement.

[0055] In one embodiment, if Figure 4 As shown, choose to use Figure 3 For the bottom plate steel bars of the same steel bar structure, the first camera and the second camera with a horizontal angle are respectively set on the top and the right side of the bottom plate steel bars. At this time, the pads in the bottom plate steel bars are arranged in a plum blossom shape. The plum blossom shape can make the pads evenly distributed, increase the friction between the steel bars and the concrete, thereby improving the bearing capacity and seismic resistance of the concrete structure. The current plum blossom shape arrangement of the pads also meets the condition that at least one pad is provided in each column and each row below the staggered position of the vertical steel bars and the horizontal steel bars. The end face of the steel bar photographed by the current camera is also above the pad, and the position of the steel bar can be judged by the pad.

[0056] Based on the above settings, a bottom plate reinforcement binding auxiliary monitoring method based on pad identification can be implemented, such as Figure 1 As shown, the method specifically comprises the following steps:

[0057] S0. Before the bottom plate reinforcement is tied, obtain the current reference image captured by the current camera;

[0058] S1. During the process of binding the bottom plate steel bars, the sound generated by the steel bar binding is detected by a sound sensor. When the sound sensor detects a sound signal exceeding a preset threshold, the current time point is recorded;

[0059] S2, extracting the current video stream shot by the camera at the current time point, and performing key frame sampling processing on the extracted current video stream to obtain multiple pictures to be identified arranged in time order;

[0060] S3. The image to be identified and the current reference image are processed in columns according to the order of the pad position captured by the camera, and the pads under the end faces of the steel bars in each column are marked with positioning lines. According to the positioning lines, it is determined in turn whether the position of the current end face of the steel bar on the pad in the image to be identified is consistent with that in the reference image. If not, the position of the pad that has been offset is obtained and a steel bar offset warning is issued.

[0061] In this embodiment, S3 specifically includes the following steps:

[0062] S31: performing image column processing on the image to be identified and the current reference image according to the position sequence of the pad blocks captured by the camera, to obtain a plurality of image column data to be identified and a plurality of reference image column data;

[0063] S32: matching the to-be-recognized picture column data with the reference picture column data according to the block position sequence of the blocks in the to-be-recognized picture column data and the block position sequence of the blocks in the reference picture column data;

[0064] S33: marking the pads below the end faces of the steel bars in the mutually matching to-be-identified image column data and the reference image column data according to the pad position sequence, and obtaining the positioning lines on the pad surfaces on the to-be-identified image column data and the reference image column data respectively;

[0065] S34: Judge the pictures to be identified in turn to determine whether the positioning line on the pad surface in the picture column data to be identified is consistent with the positioning line on the pad surface in the matching reference picture column data; if not, obtain the offset pad position and issue a steel bar offset warning.

[0066] Preferably, in S31, the process of image segmentation processing is specifically as follows:

[0067] First, target image recognition is performed on the pads in the image to be identified and the reference image. When the pad is identified, the image to be identified and the reference image are cut with the identification frame where the pad is located, and multiple image column data to be identified and multiple reference image column data are generated respectively, and the multiple image column data to be identified and multiple reference image column data are numbered according to the order of the pad position. The purpose is to magnify the pads in the image to be identified and the reference image by cutting the image to be identified and the reference image, so as to magnify the pads, facilitate the subsequent positioning line marking of the pad surface with the characteristic points of the steel bar end face, and each pad can be numbered to accurately obtain the position of the pad, thereby prompting the staff.

[0068] Preferably, in S33, the process of marking the positioning line is specifically as follows:

[0069] Draw a vertical line downward on the pad according to the circular feature point corresponding to the end face of the steel bar, and mark the surface of the pad with the vertical line to form a positioning line on the surface of the pad.

[0070] Specifically, the characteristic points of the circle corresponding to the end face of the steel bar include the center point of the circle and the circumscribed point of the circle;

[0071] When a vertical line is drawn downward from the center point of the circle to the pad, the positioning line on the current pad surface passes vertically through the center point of the circle;

[0072] When a vertical line is drawn downward to the pad with the circular circumference point, the circular circumference point is located on the horizontal line passing through the center point of the circle, and the positioning line on the surface of the current pad passes vertically through the circular circumference point.

[0073] Specifically, in this embodiment, based on Figure 2 The camera in the middle can obtain the end face of the vertical steel bar and the surface of the pad. At this time, if a vertical line is drawn downward from the center point of the circle to mark the pad positioning line, a line like Figure 5 The positioning line shown in the figure can be used to determine the position on the pad and accurately determine whether the current vertical reinforcement is offset.

[0074] Preferably, in S2, the process of extracting the current video stream captured by the camera at the current time point is specifically as follows: the current time point is pushed forward and backward for a period of time in the monitoring video captured by the camera to mark the time point, and then the monitoring video is intercepted at the marked time point to obtain the current video stream. The purpose is to obtain the current video stream when a loud sound occurs, process the current video stream, and obtain the video stream through the sound sensor to avoid excessive video processing data volume and reduce system load.

[0075] Preferably, in S2, the process of performing key frame sampling processing on the extracted current video stream is specifically as follows: based on the similarity between the video frame in the current video stream and the current reference picture, the video frame whose similarity is within a predetermined range is extracted from the current video stream as a key frame. The purpose is that during the steel bar binding process, there will be workers walking back and forth or working, resulting in the camera taking a picture without a complete pad surface and steel bar end face, then the current video frame cannot be used for detection, and can be excluded, then in the present invention, a preset predetermined range is selected, if the similarity between the current video frame and the current reference picture exceeds the predetermined range, indicating that the similarity between the two is very close, then the steel bar end face and the pad end face in the current video frame have not changed significantly; if the similarity between the current video frame and the current reference picture does not exceed the predetermined range, indicating that the similarity between the two is very low, that is, there is no complete pad surface and steel bar end face in the current video frame, the picture is blocked, then the current video frame is not used for detection.
