Problems solved by technology

However, if a surface with the same area is used as an evaluation object for projection materials of different sizes, the size of the projection materials may affect the coverage evaluation
For example, when the surface of the evaluation object does not have a sufficient area for the size of the projection material, the influence of one dent on the coverage becomes large, so it may not be possible to evaluate the overall (average) coverage of the object.

no. 1 approach

[0041] figure 1 It is a configuration diagram schematically showing the evaluation system including the evaluation device according to the first embodiment. figure 1 The shown evaluation system 1 is a system for evaluating the coverage of an evaluation object. Examples of objects to be evaluated include Alman strips, gears, and springs. The coverage is the ratio of the area where the dent is caused by the impact to the entire surface area to be measured.

[0042]The evaluation system 1 includes one or more user terminals 10 and an evaluation device 20 . The user terminal 10 and the evaluation device 20 are communicably connected to each other via a network NW. The network NW may be configured by either wired or wireless. Examples of the network NW include the Internet, a mobile communication network, and a WAN (Wide Area Network: Wide Area Network).

[0118] Figure 14 It is a configuration diagram schematically showing an evaluation system including an evaluation device according to the second embodiment. Figure 14 The shown evaluation system 1A differs from the evaluation system 1 mainly in that it includes a user terminal 10A instead of the user terminal 10 and includes an evaluation device 20A instead of the evaluation device 20 .

[0119] The user terminal 10A differs from the user terminal 10 mainly in that it does not include the correction unit 13 and that a captured image is transmitted to the evaluation device 20A instead of the image for evaluation. In addition, in the user terminal 10A, the image acquisition unit 11 outputs the captured image to the transmission unit 14 . The transmission unit 14 outputs the captured image to the evaluation device 20A.

no. 3 approach

[0127] Figure 16 It is a configuration diagram schematically showing an evaluation system including an evaluation device according to the third embodiment. Figure 16 The shown evaluation system 1B differs from the evaluation system 1 mainly in that it includes a user terminal 10B instead of the user terminal 10 and that it does not include an evaluation device 20 . The user terminal 10B differs from the user terminal 10 mainly in that it further includes the evaluation unit 18 and that it does not include the transmission unit 14 and the reception unit 15 . In this case, the user terminal 10B may be a stand-alone evaluation device.

[0128] In addition, in the user terminal 10B, the correction unit 13 outputs the image for evaluation to the evaluation unit 18 . The correction information acquisition unit 17 outputs the correction information to the evaluation unit 18 . The evaluation unit 18 has the same function as the evaluation unit 22 . In other words, the evaluation...

Abstract

An evaluation system (1) is for evaluating coverage of a to-be-evaluated object by using a captured image (G) of the to-be-evaluated object. The evaluation system (1) is provided with: an image acquisition unit (11) that acquires the captured image (G); a correction unit (13) that corrects the captured image (G) to generate an evaluation image; an evaluation unit (22) that evaluates the coverage on the basis of the evaluation image; and an output unit (16) that outputs an evaluation result by the evaluation unit. The correction unit (13) extracts, from the captured image (G), an evaluation region (Re) on the basis of the size of a dent region (De) included in the captured image (G), and generates the evaluation image on the basis of the evaluation region (Re). The dent region (De) represents an image of the dent that occurs on the to-be-evaluated object.

Description

technical field [0001] The present disclosure relates to an evaluation system, an evaluation device, an evaluation method, an evaluation program, and a recording medium. Background technique [0002] In order to improve the strength of mechanical parts and the like, the surface of the mechanical parts and the like may be subjected to shot peening (shotpeening). A coverage measuring device for evaluating the degree of completion of such shot peening is known. For example, Patent Document 1 discloses a coverage measurement device that calculates a coverage based on an image obtained by photographing a processed surface, and displays the coverage. [0003] Patent Document 1: Japanese Unexamined Patent Publication No. 2011-152603 [0004] Shot peening can use various sizes of shot material. Therefore, the size of the dents formed on the processed surface varies depending on the size of the projection material. However, if a surface with the same area is used as an evaluation...
