Description

  The present invention relates to a volume calculation device, a volume calculation method, and a program, and more particularly, to a volume calculation device, a volume calculation method, and a program for calculating a volume in which ready-mixed concrete can be placed based on acquired image data.

  In construction sites, when concrete work is performed, ready-mixed concrete is sometimes placed in a pre-installed formwork.

  For example, Patent Document 1 discloses an apparatus that supports a plan for placing concrete. Patent Document 1 describes a concrete placement design drawing support apparatus that includes a model storage unit, a skeleton drawing drawing unit, a skeleton drawing division unit, and a placement amount calculation unit. According to Patent Document 1, the placement amount calculation unit specifies a component that includes at least a part of the region for each region, calculates a volume of the specified at least a portion, sums the calculated volumes, The amount of concrete placement in the area is calculated. According to Patent Document 1, the above configuration makes it possible to easily grasp the concrete placement amount for each work section.

  In addition, when placing ready-mixed concrete, it is possible to place an order for ready-mixed concrete by estimating a slightly larger quantity than the expected amount in order to ensure that the concrete work in the planned placement section of concrete will be completed as scheduled. is there. In such a case, so-called return concrete, which is the remainder of ready-mixed concrete, is generated. For example, Patent Document 2 discloses a technique for appropriately processing such return concrete. Patent Document 2 describes a method for selling return concrete.

Japanese Patent Laying-Open No. 2015-52912 JP 2002-150028 A

  Depending on the situation at the construction site, the estimated amount at the planning stage may not match the actual amount used. However, the technique of Patent Document 1 is an apparatus that supports a plan for placing ready-mixed concrete, and the actual situation of use cannot be taken into consideration. Therefore, in the case of the technique described in Patent Document 1, depending on the situation in which the ready-mixed concrete is actually placed, there is a possibility that excess or deficiency occurs in the ready-mixed concrete. In addition, as a means for considering the actual situation at the site of use, for example, there is a method in which an on-site worker actually performs surveying to calculate the amount of cast concrete. However, when such a method is used, the accuracy of the calculation result depends on the skill of the worker and the like, and stable calculation cannot always be performed. As described above, when placing ready-mixed concrete, there has been a problem that it is difficult to calculate the placement amount in consideration of the actual situation at the site.

  In addition, it is desirable not to generate return concrete as much as possible. The technique described in Patent Document 2 has a problem that although the generated return concrete can be processed, the generation of the return concrete cannot be suppressed.

  As described above, when placing ready-mixed concrete, there has been a problem that it is difficult to calculate the placement amount in consideration of the actual situation at the site.

[First Embodiment]
A first embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a diagram for explaining an outline of the volume calculation device 1. FIG. 2 is a block diagram illustrating an example of the configuration of the volume calculation device 1. FIG. 3 is a diagram illustrating an example of information included in the calculation information 163. FIG. 4 is a perspective view illustrating an example of the calculation target 2. 5 and 6 are perspective views illustrating an example of an exclusion target in the calculation target 2. FIG. FIG. 7 is a flowchart showing an example of the operation of the volume calculation device 1.

  1st Embodiment demonstrates the structure of the volume calculation apparatus 1 which calculates the placement amount of ready-mixed concrete based on the image information 161 and the depth information 162. FIG. As will be described later, the volume calculation device 1 according to the present embodiment extracts the calculation target 2 from the image information 161 based on the image information 161 and the depth information 162 and detects an exclusion target to be described later in the calculation target 2. To do. Then, the volume calculation device 1 calculates the volume of the calculation target 2 and calculates the volume of the exclusion target existing in the calculation target 2. Thereafter, the volume calculation device 1 subtracts the volume of the exclusion target existing in the calculation target 2 from the volume of the calculation target 2. Thereby, the volume calculation apparatus 1 calculates the volume in which the ready-mixed concrete can actually be placed in the calculation object 2.

  Note that the calculation target 2 refers to a target for placing ready-mixed concrete, and refers to, for example, a pre-installed frame that forms a placing space for placing ready-mixed concrete. Specifically, for example, the calculation target 2 is a wooden frame type or the like (note that the frame type may be made of iron or resin. It may be a frame (see, for example, FIG. 4). The calculation target 2 may include, for example, a frame type in which ready-mixed concrete is cast halfway, which occurs when ready-made ready-mixed concrete is insufficient. Further, the exclusion target refers to a target that is present in the calculation target 2 and obstructs the amount of ready-mixed concrete that can be placed. Examples of the exclusion target include a target intentionally present in the calculation target 2 such as the reinforcing bar 41 (see FIG. 5) present in the frame and the mesh reinforcing bar 43 illustrated in FIG. In addition, the objects to be excluded can include objects that do not exist intentionally, such as unevenness (for example, gravel 42) on the ground or the placement site base (see FIG. 6). The calculation target 2 and the exclusion target may be other than those exemplified above.

  The volume calculation device 1 is an information processing device such as a personal computer having an image capturing unit 11 and a depth sensor 12, for example. As shown in FIG. 1, the volume calculation device 1 captures a calculation target 2 that is a target for placing ready-mixed concrete with an image capturing unit 11 and acquires image information 161. The volume calculation device 1 acquires depth information 162 corresponding to the image information 161 by using the depth sensor 12 when, for example, the calculation target 2 is photographed. Then, the volume calculation device 1 calculates the volume of the calculation target 2 based on the acquired image information 161 and depth information 162 in consideration of the volume of the exclusion target existing in the calculation target 2. The volume calculation device 1 may be a portable information terminal such as a smartphone or a tablet.

  FIG. 2 shows an example of the configuration of the volume calculation device 1. Referring to FIG. 2, the volume calculation device 1 includes, as main components, an image capturing unit 11 (image capturing unit), a depth sensor 12, a communication I / F unit 13, an operation input unit 14, and a screen display. A unit 15, a storage unit 16, and an arithmetic processing unit 17.

  The image photographing unit 11 includes an image photographing device such as a digital camera or a digital video camera. The image photographing unit 11 obtains image data by photographing the calculation target 2 which is a target for placing ready-mixed concrete. In other words, the image capturing unit 11 acquires image data including a frame that forms a placement space. Image data acquired by the image capturing unit 11 is stored in the storage unit 16 as image information 161 by the image information acquisition unit 171. Note that, when the image capturing unit 11 captures the calculation target 2, the reference body 3 that is installed in the vicinity of the calculation target 2 and has a known length (for example, the length of the reference body 3 is a volume in advance). It is desirable to photograph together (which is set in the calculation device 1). Thereby, the volume calculation device 1 can easily calculate the length of the calculation object 2 and the like.

  The depth sensor 12 is, for example, an infrared depth sensor. For example, the depth sensor 12 uses infrared rays to acquire depth information corresponding to the image data acquired by the image capturing unit 11. For example, when the image capturing unit 11 acquires image data, the depth sensor 12 acquires depth information of each coordinate in a region indicated by the image data. The depth sensor 12 may acquire depth information at a timing different from the timing at which the image capturing unit 11 acquires image data. The depth information acquired by the depth sensor 12 is stored in the storage unit 16 as depth information 162 by the depth information acquisition unit 172. In addition, since acquisition of the depth information 162 using infrared rays is a known technique, the details of the method are omitted.

  The communication I / F unit 13 includes a dedicated data communication circuit. The communication I / F unit 13 performs data communication with various devices connected via a communication line.

  The operation input unit 14 includes, for example, an operation input device such as a keyboard and a mouse. The operation input unit 14 detects an operation of an operator who operates a keyboard, a mouse, and the like and outputs the operation to the arithmetic processing unit 17.

  The screen display unit 15 includes a screen display device such as an LCD (Liquid Crystal Display). The screen display unit 15 displays various information such as image information 161, depth information 162, and calculation information 163 on the screen according to instructions from the arithmetic processing unit 17.

  The storage unit 16 is a storage device such as a hard disk or a memory. The storage unit 16 stores processing information and programs 164 necessary for various processes in the arithmetic processing unit 17. The program 164 is a program that realizes various processing units by being read and executed by the arithmetic processing unit 17. The program 164 is read in advance from an external device (not shown) or a storage medium (not shown) via a data input / output function such as the communication I / F unit 13 and stored in the storage unit 16. Main information stored in the storage unit 16 includes image information 161, depth information 162, and calculation information 163.

  The image information 161 is information indicating image data acquired by the image capturing unit 11 capturing the calculation target 2. In the image information 161, for example, image data, identification information for identifying the image data, meta information such as date and time when the image data was acquired, and the like are stored in association with each other. The image information 161 may include information other than those exemplified above.

  Further, as will be described later, each image data included in the image information 161 is associated with the depth information 162.

  The depth information 162 indicates depth information corresponding to the image data acquired by the image capturing unit 11. In the depth information 162, for example, identification information for identifying corresponding image data, depth information for each coordinate in the corresponding image data, other meta information, and the like are stored in association with each other. Thus, the depth information 162 is associated with the image information 161 by storing the identification information for identifying the corresponding image data and the corresponding depth information in association with each other.

  The depth information 162 may be associated with the image information 161 by having arbitrary information common to the corresponding image data instead of the identification information for identifying the image data. As described above, the configuration for associating the image information 161 and the depth information 162 is not limited to the case exemplified in this embodiment.

  The calculation information 163 indicates calculation results calculated by the temporary volume calculation unit 174, the exclusion target volume calculation unit 176, and the volume calculation unit 177. Referring to FIG. 3, the calculation information 163 includes temporary volume information 1631, exclusion target volume information 1632, and volume information 1633.

  The temporary volume information 1631 is information indicating the temporary volume calculated by the temporary volume calculation unit 174. As will be described later, the temporary volume calculation unit 174 calculates the volume of the calculation target 2 extracted by the calculation target extraction unit 173 (a volume not considering the volume to be excluded). Therefore, it can also be said that the temporary volume information 1631 indicates the volume of the calculation target 2.

  The exclusion target volume information 1632 is information indicating the exclusion target volume calculated by the exclusion target volume calculation unit 176. As will be described later, the exclusion target volume calculation unit 176 calculates the volume of the exclusion target detected by the exclusion target detection unit 175. Therefore, it can also be said that the exclusion target volume information 1632 indicates the volume to be excluded.

  The volume information 1633 is information indicating the volume calculated by the volume calculation unit 177. As will be described later, the volume calculation unit 177 calculates the volume by subtracting the exclusion target volume of the exclusion target in the calculation target 2 from the temporary volume of the calculation target 2. Therefore, it can also be said that the volume information 1633 indicates a value obtained by subtracting the volume to be excluded from the volume of the calculation target 2, that is, a volume in which ready-mixed concrete can actually be placed.

  Note that each piece of information (image information 161, depth information 162, calculation information 163) stored in the storage unit 16 is transmitted to the external device via the communication I / F unit 13 under the control of the arithmetic processing unit 17, for example. Or can be displayed on the screen display unit 15.

  The arithmetic processing unit 17 includes a microprocessor such as an MPU (Micro-processing unit) and its peripheral circuits, and reads the program 164 from the storage unit 16 and executes it, thereby causing the hardware and the program 164 to cooperate. Various processing units are realized. As main processing units realized by the arithmetic processing unit 17, an image information acquisition unit 171, a depth information acquisition unit 172, a calculation target extraction unit 173 (extraction unit), and a temporary volume calculation unit 174 (temporary volume calculation unit). And an exclusion target detection unit 175 (detection unit), an exclusion target volume calculation unit 176 (volume calculation unit), and a volume calculation unit 177 (volume calculation unit).

  The image information acquisition unit 171 acquires image data from the image capturing unit 11 and stores the acquired image data in the image information 161 of the storage unit 16. That is, the image information acquisition unit 171 acquires image data from the image capturing unit 11. Then, the image information acquisition unit 171 stores the acquired image data in the image information 161 of the storage unit 16.

  The depth information acquisition unit 172 acquires depth information from the depth sensor 12 and stores the acquired depth information in the depth information 162 of the storage unit 16. That is, the depth information acquisition unit 172 acquires depth information from the depth sensor 12. Then, the depth information acquisition unit 172 stores the acquired depth information in the depth information 162 of the storage unit 16.

  The calculation target extraction unit 173 extracts the calculation target 2 from the image data based on the image information 161. For example, the calculation target extraction unit 173 performs the extraction by detecting an edge using a differential operation, a high-pass filter, or the like, or performing region division such as division / integration method. Note that the calculation target extraction unit 173 may use a known method other than that exemplified above as long as the calculation target 2 can be extracted from the image data.

  For example, the calculation target extraction unit 173 extracts, as the calculation target 2, a frame type that is a frame for placing ready-mixed concrete (that is, a frame forming a placement space) as illustrated in FIG. Then, the calculation target extraction unit 173 notifies the extraction result to the temporary volume calculation unit 174 and the exclusion target detection unit 175.

  The temporary volume calculation unit 174 calculates the volume of the calculation target 2 extracted by the calculation target extraction unit 173. For example, the temporary volume calculation unit 174 estimates the length of the calculation target 2 by referring to the reference body 3 having a known length and comparing the reference body 3 with the calculation target 2. Further, the temporary volume calculation unit 174 estimates the depth of the calculation target 2 with reference to the depth information 162. At this time, the temporary volume calculation unit 174 ignores the influence of the gravel 42 and the like existing in the calculation target 2, for example, estimating the average value of the depth information 162 in the calculation target 2 as the depth of the calculation target 2. The depth of the calculation object 2 can be estimated. Then, the temporary volume calculation unit 174 calculates the volume of the calculation target 2 based on the estimated length and depth. Thereafter, the temporary volume calculation unit 174 stores information indicating the calculated temporary volume in the calculation information 163.

  The temporary volume calculation unit 174 is configured to calculate the temporary volume using, for example, a value input via the operation input unit 14 (or a value acquired via the communication I / F unit 13). It doesn't matter. The temporary volume calculation unit 174 may be configured to input a part of values used when calculating the temporary volume via the operation input unit 14 or the like.

  In addition, depending on the shooting angle of the image shooting unit 11, the lengths and depths of all the portions necessary for calculating the temporary volume may not be clear based on the image data. In such a case, the temporary volume calculation unit 174 can be configured to estimate the length and depth of the unknown part from the length and depth of the obvious part. For example, it can be assumed that the depth of the calculation target 2 is not substantially changed at any point (or can be divided into a plurality of regions having no change) or is a continuous change. Therefore, the calculation target 2 can be configured to estimate that the depth of the unknown part is the same as the depth of the obvious part, for example.

  The exclusion target detection unit 175 detects an exclusion target existing in the placement space based on the image information 161, the depth information 162, and the like. For example, the exclusion target detection unit 175 may include edge detection, area division, pattern matching (for example, a target intentionally present in the calculation target 2 such as the reinforcing bar 41 and the mesh line 43, gravel 42, etc.) from the image data. The exclusion target existing in the placement space is detected by using a known method such as matching with a template indicating an assumed target. Further, the exclusion target detection unit 175 can be configured to detect the exclusion target with reference to the depth information 162. For example, based on the depth information 162, the exclusion target detection unit 175 may estimate that there is an exclusion target at a location in the calculation target 2 where an abrupt change in depth (a change exceeding a predetermined threshold) occurs. I can do it. Further, the exclusion target detection unit 175 can be configured to detect the unevenness of the ground in the calculation target 2 such as the gravel 42 based on the depth information 162.

  Specifically, for example, as illustrated in FIG. 5, the exclusion target detection unit 175 detects the reinforcing bar 41 as an exclusion target existing in the calculation target 2. Further, for example, in the case as shown in FIG. 6, the exclusion target detection unit 175 detects the mesh streaks 43 and the gravel 42 as the exclusion targets existing in the calculation target 2. In this way, the exclusion target detection unit 175 detects an exclusion target (an intentionally existing target and an unintentional target) that hinders the amount of ready-mixed concrete that exists in the calculation target 2. Then, the exclusion target detection unit 175 notifies the detection result to the exclusion target volume calculation unit 176.

  The exclusion target volume calculation unit 176 calculates the volume of the detected exclusion target in response to the notification from the exclusion target detection unit 175. For example, the exclusion target volume calculation unit 176 estimates the length of the exclusion target based on the length of the reference body 3, which is a known length, and the like in the same manner as the temporary volume calculation unit 174 described above. Calculate the volume of the object. Alternatively, for example, it is assumed that the exclusion target volume calculation unit 176 includes a target intentionally present in the calculation target 2 such as the volume of one reinforcing bar 41 or the volume of the mesh bar 43, or gravel 42. You can have a database showing the volume of interest. Then, the exclusion target volume calculation unit 176 calculates the volume of the exclusion target detected by the exclusion target detection unit 175 based on the detection result by the exclusion target detection unit 175 and the database.

  For example, the exclusion target volume calculation unit 176 calculates the exclusion target volume based on the detection result from the exclusion target detection unit 175 by the method described above. Thereafter, the exclusion target volume calculation unit 176 stores information indicating the calculated exclusion target volume in the calculation information 163.

  The volume calculation unit 177 calculates the volume of the calculation target 2 in which ready-mixed concrete can actually be placed by subtracting the volume of the exclusion target existing in the calculation target 2 from the volume of the calculation target 2. For example, the volume calculation unit 177 refers to the calculation information 163 and acquires the temporary volume of the calculation target 2 and the exclusion target volume that is the volume of the exclusion target existing in the calculation target 2. Then, the volume calculation unit 177 calculates the final volume by subtracting the exclusion target volume from the temporary volume. Thereafter, the volume calculation unit 177 stores information indicating the calculated volume in the calculation information 163.

  The various processing units realized by the arithmetic processing unit 17 transmit the acquired results, the extracted / detected results, and the information indicating the calculated results to the external device via the communication I / F unit 13 or the screen display. Or can be displayed on the section 15. For example, the volume calculation unit 177 can transmit information indicating the calculated volume to an external device via the communication I / F unit 13 or display the information on the screen display unit 15.

  The above is the description of the configuration of the volume calculation device 1.

  Next, an example of the operation of the volume calculation device 1 will be described with reference to FIG.

  Referring to FIG. 7, the volume calculation device 1 acquires image information 161 obtained by shooting the calculation target 2 using, for example, the image shooting unit 11. Further, the volume calculation device 1 uses the depth sensor 12 to acquire depth information 162 corresponding to the acquired image information 161. As described above, the volume calculation device 1 acquires the image information 161 and the depth information 162 (step S101).

  The calculation target extraction unit 173 of the volume calculation device 1 extracts the calculation target 2 from the image information 161 (image data). (Step S102). Note that the method used by the calculation target extraction unit 173 when extracting the calculation target 2 is not particularly limited.

  The temporary volume calculation unit 174 calculates the volume of the calculation target 2 extracted by the calculation target extraction unit 173 (step S103). For example, the temporary volume calculation unit 174 estimates the length of the calculation target 2 with reference to the reference body 3 whose length is known. Further, the temporary volume calculation unit 174 estimates the depth of the calculation target 2 with reference to the depth information 162. Then, the temporary volume calculation unit 174 calculates a temporary volume that is the volume of the calculation target 2 based on the estimated length and depth.

  In parallel with the process in step S103, the exclusion target detection unit 175 detects an exclusion target in the calculation target 2 (step S104). The method used when the exclusion target detection unit 175 detects the exclusion target is not particularly limited. Then, the exclusion target volume calculation unit 176 calculates the exclusion target volume detected by the exclusion target detection unit 175 (step S105). The exclusion target volume calculation unit 176 may calculate the volume to be excluded by the same processing as in step S103, or may calculate the volume to be excluded with reference to a database created in advance.

  The volume calculation unit 177 subtracts the exclusion target volume, which is the exclusion target volume calculated in step S105, from the temporary volume calculated in step S103. Thereby, the volume calculation part 177 calculates the volume in which the ready-mixed concrete can be actually placed in the calculation object 2 (step S106).

  As described above, the volume calculation device 1 includes the exclusion target detection unit 175 and the exclusion target volume calculation unit 176. With such a configuration, the volume calculation unit 177 of the volume calculation device 1 subtracts the exclusion target volume calculated by the exclusion target volume calculation unit 176 from the temporary volume, thereby actually preparing ready-mixed concrete in the calculation target 2. Can be calculated. As a result, the volume calculation device 1 can calculate the placement amount in consideration of the actual situation at the site.

  In the present embodiment, the volume calculation device 1 includes the depth sensor 12. However, as long as the depth information can be acquired, the volume calculation device 1 does not necessarily have the depth sensor 12. For example, the volume calculation device 1 may include a plurality of image capturing units 11 instead of the depth sensor 12, and may be configured to acquire depth information using a stereo camera technique. Further, the volume calculation apparatus 1 may be configured to acquire depth information using a light field camera technique, such as providing a microlens array in front of the image sensor. Further, for example, the volume calculation device 1 may be configured to calculate the inclination of the terrain from the acquired image data and the like, and to calculate the depth information based on the inclination of the terrain.

  Further, the volume calculation device 1 may be configured to acquire the image information 161 and the depth information 162 via, for example, the communication I / F unit 13. In the case of such a configuration, the volume calculation device 1 may not include the image capturing unit 11 together with the depth sensor 12.

[Second Embodiment]
Next, a second embodiment of the present invention will be described with reference to FIG. In the second embodiment, an outline of the configuration of the volume calculation device 5 will be described.

  The volume calculation device 5 calculates the volume of the placement space that indicates the amount of ready-mixed concrete that can be placed in the placement space formed by the inside of a frame that is installed in advance. Referring to FIG. 8, the volume calculation device 5 includes an extraction unit 51, a detection unit 52, a temporary volume calculation unit 53, a volume calculation unit 54, and a volume calculation unit 55. For example, the volume calculation device 5 includes an arithmetic device (not shown) and a storage device, and the above-described units are realized by an arithmetic device (not shown) executing a program stored in the storage device (not shown).

  The extraction means 51 extracts a frame forming a placement space from the image data. Then, the extraction unit 51 notifies the detection unit 52 and the temporary volume calculation unit 53 of the extracted result. Note that the image data may be stored in the volume calculation device 5 in advance, or may be acquired by an image acquisition unit (not shown) included in the volume calculation device 5, for example.

  The detection means 52 detects an exclusion target that hinders the amount of ready-mixed concrete that exists in the placement space. Then, the detection unit 52 notifies the volume calculation unit 54 of the detected result.
