First, looking at the parts counting device 10 related to the first object described above with reference to FIG. 1 , it will be understood that FIG. 1 shows a schematic configuration diagram of the parts counting device 10 , in the present invention The mentioned parts counting device 10 may be understood to mainly include a detecting unit 11 , an estimating unit 12 , and a counting unit 13 .

If the description is continued with simultaneous reference to the schematic process example of the parts counting device 10 shown in FIG. 2 , the above-described parts counting device 10 is an image acquired through an object detection camera 20 provided in a factory It can be understood that the function is performed based on In general, each pixel has an object feature value of the object being photographed.

That is, the object detection camera 20 is installed in different directions based on a preset counting area to acquire images photographed in different directions with respect to the above-described counting area, and functions to calculate the length of the object from the image What you can do is take a picture of the surrounding environment or scene (space), and include the various objects that exist within the scene (e.g., static objects such as floors, walls, obstacles, or dynamic objects such as people and animals) of the scene. It may be implemented as a distance camera of various methods such as a stereo method, a structured light method, and a time-of-flight (ToF) method that acquires object information in real time.

In addition, one or more pieces of information acquired by the object detection camera 20 described above can function to be transmitted to the server 30 communicating with the main terminal 40 , and the counting area set in the object detection camera 20 is , can be understood as a concept corresponding to the number line, which is an area in which the quantity of parts is grasped, and that the object detection cameras 20 are installed in different directions in the previous And it will be understood that the purpose is to acquire an image photographed in a direction including at least one of a diagonal direction.

Meanwhile, the above-described detection unit 11 functions to analyze an image obtained through the object detection camera 20 to detect a motion region in the image.

At this time, it will be understood that the above-described detection unit 11 can detect the motion region by using various techniques such as a Gaussian Mixture Model (GMM) and a codebook model to detect the motion region in the image. and the present invention is not limited thereto.

Next, referring to the estimator 12 described above, the estimator 12 is an estimated part that is estimated to be located in a motion region detected based on information on the part to be counted pre-stored in the database. function to identify the area.

In this case, the above-described estimation unit 12 extracts a reference pixel having a maximum height value from the floor from the motion region previously detected by the detection unit 11, and then extracts the extracted It may be understood that the function functions to include neighboring pixels having a height value within which a difference in height between the reference pixel and the reference pixel is within a preset threshold value in the estimated part area.

As an embodiment, referring to FIG. 3 , an example in which an estimated part area is set according to an embodiment of the present invention can be seen in FIG. 3 .

Specifically, in FIG. 3 , when the conveyor belt is identified as the detected motion region, the maximum height value for an arbitrary part is extracted from the bottom surface of the conveyor belt, and then the neighboring pixels whose height difference is within a threshold are estimated as the part region It can be seen that the embodiment is included in the figure, and the estimated parts areas are estimated to be A and B.

That is, it will be understood that in the present invention, a region estimated to be the same part among several parts may be identified as an estimated part region by comparing the similarity of height values.

In addition, when two or more motion regions are detected by the function of the detector 11, the estimator 12 of FIG. 1 determines whether there is a motion region that is not a target of judgment among a plurality of detected motion regions. , may function to set estimated part areas for all detected motion areas by repeating the above-described process, but the present invention is not limited thereto.

Next, the above-described counting unit 13 recognizes the counting target part by determining whether the area ratio of the estimated part area identified by the aforementioned estimating part 12 satisfies the similarity condition set in the counting target part information. By doing so, counting is performed on the actual part.

Specifically, the above-described counting unit 13 performs tracking of the movement trajectory for the estimated part area, and when it is determined that the tracking trajectory for the estimated part area has passed through the counting line, the number of frames in which the estimated part area is detected; By calculating the ratio of the number of frames recognized as the count target part by satisfying the similarity condition, it may function to perform the counting of the actual part when the calculated ratio of the number of frames is equal to or greater than a preset threshold value.

At this time, in the present invention, to perform the counting in proportion to the number of frames, during the tracking of the movement trajectory, the part is intermittently covered by other objects or the candidate part area is not recognized as an actual part in a specific frame due to noise, etc. It will be understood that the purpose is to prevent an error in the result, that is, in the present invention, it is possible to provide the effect of improving the accuracy of counting parts by performing the function of the counting unit 13 described above.

It can be determined whether the similarity condition is satisfied, but the present invention is not limited thereto.

In addition, in relation to the performance of the function of the above-described counting unit 13, in the above-described database, as the counting target part information, the part image of the actual part is applied to the SIFT (Scale-Invariant Feature Transfrom) algorithm, First feature point information that is extracted feature point information may be stored.

In this case, the above-described SIFT algorithm is an algorithm for extracting features that are invariant to the size and rotation of the image. It extracts SIFT features from two different images, matches them with the most similar features, and detects the corresponding parts in the two images. As an algorithm, to outline the above-mentioned SIFT algorithm, first, the original image taken of the actual part is doubled, then progressively blurred, then the original image is gradually blurred, and then the original image is halved. Scale-space is implemented by repeating the process of forming a progressively blurred image from the reduced image.

Then, when the above-described scale-space is implemented, a keypoint finding is performed to calculate the Difference of Gaussian (DoG) and find the approximate location of the local maxima and minima in the image using Laplacian of Gaussian (LoG), around the key point By allocating directions to key points by collecting the gradient direction and magnitude of , and finding the most conspicuous direction, identification information such as a fingerprint is given to an image taken of an actual part to obtain the first feature point information.

That is, through this, whether the similarity condition of the counting unit 13 is satisfied is determined by whether the similarity between the above-described first characteristic point information and the second characteristic point information extracted from the estimated part area detected in the image satisfies a preset threshold value. A result value as to whether or not the above-described similarity condition is satisfied is determined.

As an example, if it is assumed that the preset threshold value matches 8 feature points, if only 8 or more feature points of the first feature point stored in the database and the second feature point information match, it can function to be recognized as a part and count In addition to the effect of realizing high reliability of the results, and the effect of reducing labor costs because the manual counting process is unnecessary, efficient logistics management is performed with data collection technology using small sensor equipment mainly used in small and medium-sized manufacturing companies. This has the effect of leading the strengthening of competitiveness of small and medium-sized manufacturing enterprises.

On the other hand, in the present invention, the preset threshold or threshold value described above or later is preferably understood as a value that can be controlled by a manager including a manager, but more preferably, a threshold at which a counting error is determined to occur greatly from the server It will be understood that the use of values may be limited.

This has the effect of being able to build a smart factory suitable for the current situation of small and medium-sized manufacturing companies.

It is preferable to include 2 location information, and detailed examples thereof can be seen in 300 and 310 of FIG. 8 .

That is, in the present invention, by performing such a function, the subject managing a plurality of small and medium-sized manufacturing plants can easily examine the logistics management status of each manufacturing plant even from a remote location, thereby increasing management efficiency.

On the other hand, in another embodiment of the present invention, when a request for inquiry of real-time monitoring data is received from the subject terminal to which the access right is granted, before the logistic report is generated in the server, when the request is received It can function to provide the collection status of the monitoring data collected until now.

On the other hand, in the present invention, when the aforementioned step S10 is performed, it is also possible to determine a case in which monitoring data that deviates from a preset threshold criterion is collected.

In this case, the collection of abnormal monitoring data may be understood as a case in which an inventory amount that does not satisfy the safety stock amount set for each part is detected, a case in which the manufacturing work environment deviates from a preset work environment range, and the like.

As an example, referring to 400 of FIG. 10 , as an embodiment in which abnormal monitoring data generation details are provided, the abnormal monitoring data is organized by date, the sender from whom the abnormal monitoring data is detected is identified, and a notification type thereof and An example in which an interface screen for checking the status is provided is illustrated.
