In one embodiment, the first light sources 111 and the second light sources 112 can be a linearly polarized light or a circularly polarized light, respectively, and the polarization direction of the first light sources 111 is different from the polarization direction of the second light sources 112. In addition, the image capturing device 12 is disposed corresponding to the object 20 to receive the reflected light of the object 20, the image capturing device 12 has a polarizer 121, the polarizer 121 is disposed at the lens portion of the image capturing device 12 and corresponding to the object 20, the polarization direction of the polarizer 121 is the same as the polarization direction of the first light sources 111 or the polarization direction of the second light sources 112, and the polarizer 121 is used to filter the light of the first light sources 111 or the light of the second light sources 112. In one embodiment, the image capturing device 12 may be a camera or the like. Further, the operation module 13 is in information connection with the image capturing device 12, the operation module 13 receives two image data 122 transmitted by the image capturing device 12, the two image data 122 are data obtained when the image capturing device 12 is respectively in a state where the annular light source generating device 11 only provides the first light sources 111 and a state where the annular light source generating device 11 only provides the second light sources 112, the operation module 13 performs an operation on the two image data 122 to obtain an identification result data 131, and the identification result data 131 is used for identifying and reading the color space of the object 20.

Referring to fig. 1 to 4, an embodiment of the image-based color recognition system 10 of the present invention will be described, and for convenience of description, the implementation of the present invention is assumed that the polarization direction of the polarizer 121 is the same as the polarization direction of the first light sources 111, and it is assumed that the annular light source generator 11 is not projected on the object 20 initially. In addition, in the implementation, the first light sources 111 are controlled by the annular light source generator 11 to project light on the object 20 to be tested, after the first light sources 111 project on the object 20 to be tested, the object 20 to be tested reflects the first light sources 111 and is received by the image capturing element 12, at this time, the image capturing element 12 does not filter the light of the first light sources 111 by the polarizer 121, so that the image captured by the image capturing element 12 is an unpolarized image. Moreover, the second light sources 112 are also controlled to project on the object 20 to be measured, after the second light sources 112 irradiate on the object 20 to be measured, the object 20 to be measured reflects the second light sources 112 and is received by the image capturing element 12, and the light of the second light sources 112 enters the image capturing element 12 and is filtered by the polarizer 121, so that the image captured by the image capturing element 12 is a polarized image. Then, the image capturing device 12 generates the two image data 122 based on the two images projected on the object 20 by the first light sources 111 and the second light sources 112, the image capturing device 12 transmits the two image data 122 to the operation module 13, and the operation module 13 performs operation analysis based on the two image data 122 and provides the identification result data 131, so that the user can read the identification result data to identify the color of the object 20.

Compared with the prior art, the utility model discloses see through and set up this ring type light source and produce piece 11 to make this ring type light source produce piece 11 and throw respectively with these a little first light source 111 and these a little second light source 112 to this determinand 20 with the mode of alternating, see through this image acquisition component 12 simultaneously and pick up and only throw produced this image data 122 with these a little first light source 111 or these a little second light source 112 respectively, borrow this order the utility model discloses this operation module 13 can judge this determinand 20's color more accurately.

In an embodiment, each of the first light sources 111 and each of the second light sources 112 may be a vertically polarized light or a horizontally polarized light, and specifically, if the first light sources 111 are the vertically polarized light and the second light sources 112 are the horizontally polarized light, the polarization direction of the polarizer 121 may be a vertical direction or a horizontal direction, that is, the polarizer 121 may be used to filter the light of the first light sources 111 or the light of the second light sources 112. On the contrary, the first light sources 111 may be the horizontally polarized light and the second light sources 112 are the vertically polarized light according to the implementation requirement, and the polarizer 121 may also be used to filter the first light sources 111 or the second light sources 112. In another embodiment, the first light sources 111 and the second light sources 112 may be right-handed polarized light or left-handed polarized light according to the implementation, and the polarizer 121 is circularly polarized, i.e., the polarization direction of the polarizer 121 may be a right-handed polarization direction or a left-handed polarization direction, so that the polarizer 121 filters the light of the first light sources 111 or the light of the second light sources 112.

In view of the above, in one embodiment, in order to make the identification result data 131 more accurate, the ring-shaped light source generator 11 and the image capturing device 12 can be disposed in a chamber (not shown), so that the image capturing device 12 can be prevented from being interfered by ambient light during implementation. Further, the annular light source generator 11 has an inner annular region 113 defined by the first light sources 111 and the second light sources 112, and the projection position 123 of the image capturing device 12 is located in the inner annular region 113.

In other words, the image capturing device 12 of the present invention is disposed above the annular light source generating member 11 and is at a high level relative to the annular light source generating member 11.

Furthermore, in an embodiment, the identification result data 131 can be obtained by removing a reflective data based on the two image data 122 and performing color separation. On the other hand, after the computing module 13 obtains the two image data 122 transmitted by the image capturing device 12, the computing module 13 may first remove the reflection data based on the two image data 122, so as to remove the reflection in the image. Then, the operation module 13 performs color separation processing on the two image data 122 from which the reflective data has been removed, so that the identification result data 131 analyzed by the operation module 13 more conforms to the actual color of the object 20.
