In view of this, this application creatively provides a light filling lamp plate and brush palm check out test set, and it can reduce the quantity of light filling lamp when even light filling for equipment overall dimension is less, is convenient for satisfy the equipment integration demand of different scenes.

Specifically, referring to fig. 1 to 5 of the drawings in the specification of the present application, there is provided a brush palm detection apparatus 1 according to an embodiment of the present application, which may include a detection apparatus body 10 and a light supplementing lamp panel 20, the light supplementing lamp panel 20 being mounted to the detection apparatus body 10 for supplementing light to the detection apparatus body 10. It should be understood that the specific peripheral shape and design of the device and the light-compensating light panel and the assembly design of the components of the device mentioned in the present application may be adjusted according to practical applications, and the following description and the accompanying drawings are only illustrative and not limiting.

More specifically, as shown in fig. 2, 3 and 5, the light compensating lamp panel 20 may include a PCB 21, a light compensating lamp group 22 and a light homogenizing member group 23. The PCB 21 has an infrared sensing region 211 and a white light sensing region 212 arranged along a first direction. The light compensating lamp set 22 comprises a pair of infrared light compensating lamps 221 and a pair of white light compensating lamps 222, wherein the two infrared light compensating lamps 221 are arranged on the PCB 21 at intervals along a second direction perpendicular to the first direction and symmetrically distributed on two opposite sides of the infrared light sensing region 211; the two white light compensating lamps 222 are disposed on the PCB 21 at intervals along the second direction and symmetrically distributed on two opposite sides of the white light sensing region 212. The light homogenizing component set 23 includes a pair of infrared light homogenizing components 231 and a pair of white light homogenizing components 232, where the two infrared light homogenizing components 231 are respectively disposed on the light emitting sides of the two infrared light compensating lamps 221, and are used to respectively homogenize the infrared light emitted by the two infrared light compensating lamps 221 to form two partially overlapped infrared light compensating spots, so that the overlapped part of the two infrared light compensating spots covers the infrared field area corresponding to the infrared light compensating area 211; the two white light homogenizing members 232 are respectively disposed on the light emitting sides of the two white light compensating lamps 222, and are configured to respectively homogenize the white light emitted by the two white light compensating lamps 222 to form two partially overlapped white light compensating light spots, so that the overlapped portion of the two white light compensating light spots covers the white light field area corresponding to the white light photosensitive area 212.

It should be noted that, as shown in fig. 2, the inspection apparatus main body 10 of the present application may include a housing assembly 11, a main board 12 disposed on the housing assembly 11, and an infrared camera module 13 and an RGB camera module 14 respectively installed on the main board 12; the light compensating lamp panel 20 is correspondingly mounted on the housing assembly 11, and the infrared camera module 13 and the RGB camera module 14 are respectively located in the infrared sensing area 211 and the white light sensing area 212 of the PCB 21, i.e. two infrared light compensating lamps 221 are symmetrically disposed on two opposite sides of the infrared camera module 13 for infrared light compensation, and two white light compensating lamps 222 are symmetrically disposed on two opposite sides of the RGB camera module 14 for white light compensation. It is understood that the infrared view field region mentioned in the present application refers to the field of view region of the infrared camera module 13; the white light field area referred to in this application refers to the field area of the RGB camera module 14. Further, the first direction mentioned in the present application may refer to a direction corresponding to a horizontal angle of view of the camera module, as a left-right direction shown in fig. 3; the second direction mentioned in the present application may refer to a direction corresponding to a vertical field angle of the camera module, such as an up-down direction shown in fig. 3.

Thus, as shown in fig. 5, since the two infrared light homogenizing members 231 can homogenize the infrared light emitted by the two infrared light compensating lamps 221 into two partially overlapped infrared light compensating spots, so that the overlapped part of the two infrared light compensating spots covers the field area of the infrared camera module 13, the brush palm detection device 1 of the present application can realize the uniform effect of the infrared light compensating only by configuring the two infrared light compensating lamps 221, and does not need to set a circle of infrared light compensating lamps around the infrared camera module 13. Similarly, since the two white light homogenizing members 232 can homogenize the white light emitted by the two white light compensating lamps 222 into two white light compensating light spots which are partially overlapped, so that the overlapped part of the two white light compensating light spots covers the field of view area of the RGB camera module 14, the brush palm detection device 1 of the present application can realize the uniform effect of white light compensating only by configuring the two white light compensating lamps 222, and does not need to set a circle of white light compensating lamps around the RGB camera module 14, which is helpful for reducing the volume of the device.

Alternatively, as shown in fig. 2 and 3, the infrared light compensating lamps 221 and the white light compensating lamps 222 located at the same side may be arranged at intervals along the first direction so as to be arranged in parallel with the infrared camera module 13 and the RGB camera module 14, which helps to avoid structural interference while achieving a desired light compensating function.

Alternatively, as shown in fig. 3, the ir dodging component 231 can include a mounting bracket 2311 and a dodging element 2312 fixedly mounted to the mounting bracket 2311, the mounting bracket 2311 is mounted to the PCB 21 around the ir light compensating lamp 221 to suspend the dodging element 2312 in the light emitting path of the ir light compensating lamp 221. In this way, the mounting bracket 2311 can protect the infrared light compensating lamp 221 in addition to supporting the light homogenizing element 2312, and ensure that all the infrared light emitted from the infrared light compensating lamp 221 can be homogenized by the light homogenizing element 2312. It will be appreciated that the mounting bracket 2311 may be mounted to the PCB 21 by means of a solder mount to wrap around the infrared light source 221.

Optionally, the mounting bracket 2311 has a rectangular cylindrical structure, and the light homogenizing element 2312 has a rectangular plate structure, so as to homogenize the infrared light spots of the infrared light compensating lamp 221 into uniform rectangular light spots, so as to better match the rectangular field of view of the infrared camera module 13, and improve the light compensating efficiency and the light compensating quality.

It should be noted that the white light homogenizing element 232 may have the same structure as the infrared homogenizing element 231, and this will not be repeated herein.

Optionally, as shown in fig. 2 and 3, the PCB 21 is stacked on the front side of the main board 12, and the PCB 21 further has a through hole 210 opened in the infrared sensing region 211 and the white light sensing region 212, so that the infrared camera module 13 and the RGB camera module 14 pass through the through hole 210 to protrude out of the PCB 21.

In other examples of the present application, the PCB 21 may also be stacked on the rear side of the main board 12, and at this time, the main board 12 needs to be correspondingly provided with a through hole, so that the infrared light homogenizing element 231 and the white light homogenizing element 232 respectively penetrate through the corresponding through holes to extend out of the main board 12, which is not described herein.

Alternatively, the infrared light compensating lamp 221 and the white light compensating lamp 222 may be electrically connected to the PCB 21 by, but not limited to, surface mounting technology; the PCB 21 may be, but is not limited to, electrically connected to the motherboard 12 by a flexible circuit board; the infrared camera module 13 and the RGB camera module 14 may be, but not limited to, electrically connected to the main board 12 through a circuit board connector, so as to control the operation of the infrared light filling lamp 221, the white light filling lamp 222, the infrared camera module 13 and the RGB camera module 14 through the main board 12 to perform palm detection.

Optionally, as shown in fig. 1 and 2, the housing assembly 11 may include a front shell 111, a rear cover 112 and a protective glass 113, wherein the rear cover 112 is fixedly connected to the front shell 111 to form a containing space for accommodating the light compensating lamp panel 20, the main board 12, the infrared camera module 13 and the RGB camera module 14, and the protective glass 113 is fixedly arranged on the front shell 111 to form a light window 110 corresponding to the infrared light compensating lamp 221, the white light compensating lamp 222, the infrared camera module 13 and the RGB camera module 14. Thus, the infrared light emitted by the infrared light compensating lamp 221 illuminates the field of view of the infrared camera module 13 through the light window 110, so as to be reflected by the palm, and then pass through the light window 110 to be received by the infrared camera module 13 to obtain palm vein information; the white light emitted from the white light compensating lamp 222 illuminates the field of view of the RGB camera module 14 through the light window 110, so as to be reflected by the palm, and then pass through the light window 110 to be received by the RGB camera module 14 to obtain palm print information.

It should be noted that, the front case 111 is designed with holes at the positions corresponding to the camera module and the light compensating lamp, so as to form the required light window 110 after the protective glass 113 is installed. For example, the front case 111 may be provided with a plurality of light holes spaced apart from each other to correspond one by one to the two infrared light compensating lamps 221, the two white light compensating lamps 222, the one infrared camera module 13 and the one RGB camera module 14, so as to weaken or avoid stray light interference formed inside the apparatus.

It should be noted that, when collecting palmprint information, the white light-compensating lamp 222 is turned on to compensate light, and the RGB camera module 14 is used to obtain palmprint image; when collecting the palm vein information, since the vein is hidden under the epidermis, the palm vein information needs to be collected by utilizing the characteristic that human hemoglobin absorbs red light, and therefore, the infrared light supplementing lamp 221 needs to be turned on to supplement light, and at this time, the palm vein image is obtained through the infrared camera module 13.

In addition, in the process of light supplementing by the infrared light supplementing lamp, a part of infrared light is reflected by the palm epidermis, so that palm print information exists in the palm vein image shot by the infrared shooting module, and the collection of the palm vein information is affected; therefore, the polarizing film is attached to the back of the protective glass in the prior art, so that the characteristic of polarized light is utilized to play a role in weakening palm reflection, palm print information is filtered out, and only palm vein information is reserved. However, the back surface of the cover glass 113 generally requires a screen printing ink, which causes the back surface of the cover glass 113 to be uneven, and in this case, if the polarizing film is directly attached to the back surface of the cover glass 113, there is a height difference, resulting in a significant reduction in yield.

To solve this problem, as shown in fig. 2 and 3, the light compensating lamp panel 20 of the present application may further include an infrared polarizing film 24 disposed at the infrared light homogenizing member 231, and the infrared polarizing film 24 is positioned at a light emitting path of the infrared light compensating lamp 221 for polarizing infrared light emitted through the infrared light compensating lamp 221 to form infrared polarized light. Thus, the infrared polarization film 24 does not need to be attached to the protective glass 113 with uneven surfaces, the mounting difficulty is reduced, and the process yield is improved.

Alternatively, the infrared polarizing film 24 may be attached to the surface of the light homogenizing element 2312 by, but not limited to, adhesive.

According to the above embodiment of the present application, as shown in fig. 4, the infrared camera module 13 may include a photosensitive substrate 131, a lens mount 132 fixedly mounted on the photosensitive substrate 131, a lens 133 assembled on the lens mount 132, a color filter 134 disposed between the lens 133 and the photosensitive substrate 131, and a module polarizing film 135 attached to the color filter 134; the polarized light film 135 and the polarized light direction of the infrared polarized light film 24 form a preset angle, so that the characteristic of polarized light is utilized, the effect of eliminating the palm reflection in the non-palm vein area on the palm surface is achieved, and the palm print information is filtered out, so that the infrared image generated by the infrared camera module 13 only retains the palm vein information. It is understood that the preset included angle referred to in this application may be, but is not limited to, between 60 ° and 90 °.

Alternatively, as shown in fig. 4, the color filter 134 may be mounted to the lens base 132 by, but not limited to, dispensing; the lens 133 can be screwed to the lens base 132; the lens base 132 may be fixed to the photosensitive substrate 131 by, but not limited to, dispensing. It is understood that the photosensitive substrate 131 mentioned in the present application may be implemented as a circuit substrate on which an infrared sensing chip is mounted, and the circuit substrate may be electrically connected to the main board 12 through a board-to-board connector.

It should be noted that, the RGB camera module 14 of the present application, like the conventional camera module, may include, but is not limited to, a photosensitive element, a filtering element and an accepting lens, which is not described herein.

It should be noted that, according to another aspect of the present application, an embodiment of the present application may further provide an electronic device, which may include the above-mentioned palm detection device 1 and other external devices (not shown in the figure), where the palm detection device 1 is integrated with the other external devices, so as to meet the device integration requirements of different scenarios, so that the electronic device has the palm detection function.

The technical features of the above embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

The foregoing examples represent only a few embodiments of the present application, which are described in more detail and are not to be construed as limiting the scope of the claims. It should be noted that it would be apparent to those skilled in the art that various modifications and improvements could be made without departing from the spirit of the present application, which would be within the scope of the present application.
