[0035] Figure 1 A flowchart of a method for measuring the volume of an article against human interference is shown.

[0036] As shown in the figure, a method for measuring the volume of an article against human interference includes the steps of:

[0037] S1, obtaining an article image, removing background information in the image, and performing binaryzation processing.

[0038] S2, finding the outline of the article, and determining whether the outline of the article extends to the boundary of the field of view. If yes, go to step S4, if no, go to step S3. The boundary of the field of view usually refers to the boundary of the entire image containing the article.

[0039] S3, measuring the volume of the article, and going to step S7.

[0040] S4, removing irregular parts in the outline of the article by morphological method. If it can be removed, go to step S5, if it cannot be removed, go to step S6.

[0041] S5, according to the profile of the article after removing the irregular part, the volume measurement of the article is carried out, a first warning is given, and step S7 is entered;

[0042] S6, a second warning is given, and step S7 is entered;

[0043] S7, end.

[0044] Preferably, in step S2, the profile of the article is found, the profile of the article is compared with the boundary of the field of view, and it is judged whether the profile of the article extends to the boundary of the field of view.

[0045] Preferably, in step S3, before the volume measurement of the article is carried out, it is judged whether the profile of the article is regular. It is easily understood that the entry into step S3 indicates that there is no personnel interference, and the profile of the article is irrelevant to the boundary of the field of view. The article with a regular profile is more conducive to the subsequent measurement work. More preferably, whether the profile of the article is regular is judged according to the concave-convex characteristics of the profile of the article.

[0046] Conventionally, if there is no personnel interference, the volume measurement of the article is completed through steps S1 to S3, and no additional calculation amount is generated. The calculation amount of the remaining steps is extremely small, and is less than 1% of the overall measurement calculation amount. Therefore, the method for measuring the volume of the article provided by the application only increases a very small amount of work and can effectively improve the efficiency of the volume measurement of the article.

[0047] Preferably, the content of the first warning in step S5 is to prompt the intervention of personnel, and the system can consider reacquiring the article picture after removing the interference.

[0048] Preferably, the content of the second warning in step S6 is to prompt the intervention of personnel and / or the article exceeding the boundary of the field of view, and the system needs to remove the interference or correctly place the article to reacquire the article picture.

[0049] Embodiment one:

[0050] Figure 2-1 An article image is shown. Figure 2-2 is Figure 2-1 After removing the background information and carrying out the binarization processing, the result is shown. As shown in the figure, the method for measuring the volume of the article provided by the application is executed.

[0051] S1, an article image is acquired, referring to Figure 2-1 . The process of removing the background information in the image and carrying out the binarization processing to present the entire image with obvious black and white effects. The article image after the binarization processing is obtained. Figure 2-2 .

[0052] S2, the profile of the article is found, and it is judged whether the profile of the article extends to the boundary of the field of view. Figure 2-2The outline of the object is the outer edge of the white image, and the field of view boundary is the outer edge of the black square. Obviously, the outline of the object is not in contact with the field of view boundary. Go to step S3.

[0053] S3, perform volume measurement of the object. Go to step S7.

[0054] S7, end.

[0055] Example one is the object volume measurement process without interference.

[0056] Example two:

[0057] Figure 3-1 An image of an object with personnel interference is shown, which has been binarized.

[0058] Figure 3-2 is Figure 3-1 The result after removing the irregular part in the outline of the object. As shown in the figure, a method for measuring the volume of an object provided by the present application is performed to prevent personnel interference.

[0059] S1, obtain the image of the object, remove the background information in the image, and perform binarization processing, refer to Figure 3-1 .

[0060] S2, find the outline of the object, and determine whether the outline of the object extends to the field of view boundary. Figure 3-1 The outline of the object is the outer edge of the intermediate gray image, and the field of view boundary is the outer edge of the black square. Obviously, the outline of the object intersects with the field of view boundary. Go to step S4.

[0061] S4, remove the irregular part in the outline of the object by morphological method, refer to Figure 3-2 , the irregular part in the outline of the object has been removed, go to step S5.

[0062] S5, according to the outline of the object after removing the irregular part, perform volume measurement of the object. Give a first warning to prompt personnel intervention (interference). Go to step S7;

[0063] S7, end.

[0064] Example three:

[0065] Figure 4 An image of an object with interference after binarization is shown. As shown in the figure, a method for measuring the volume of an object provided by the present application is performed to prevent personnel interference.

[0066] S1, obtain the image of the object, remove the background information in the image, and perform binarization processing, refer to Figure 4 .

[0067] S2, find the outline of the object, determine whether the outline of the object extends to the boundary of the field of view. Figure 4 The outline of the object is the outer edge of the intermediate white image, and the boundary of the field of view is the outer edge of the black square. Obviously, the outline of the object intersects with the boundary of the field of view. Go to step S4.

[0068] S4, by morphological method, the irregular part in the outline of the object cannot be removed. Go to step S6.

[0069] S6, give a secondary warning, prompt personnel intervention and / or the object exceeds the boundary of the field of view. Go to step S7;

[0070] S7, end.

[0071] Example three cannot obtain measurement results, and needs to exclude personnel interference or adjust the position of the object to reacquire the object image.

[0072] The present application provides an object volume measurement method for preventing personnel interference, which can effectively detect the interference of the hands and other limb parts of the auxiliary measurement personnel in the volume measurement process. The interference area is located, and a judgment is made according to the interference degree. When the measured object is not seriously blocked, the interference part can be removed and the correct measurement result is obtained, or when the measured target is seriously blocked or placed incorrectly, the system is prompted to reacquire the picture of the measured target.

[0073] It is obvious to those skilled in the art that various modifications and variations can be made to the above exemplary embodiments of the present application without departing from the spirit and scope of the present application. Therefore, it is intended to cover modifications and variations of the present application falling within the scope of the appended claims and their equivalents.
