Fig. 2a and fig. 2b are schematic diagrams illustrating an interaction flow of the light spot video collecting device of the light supplementing module shown in fig. 1 and a terminal device.

Referring to fig. 2a, the camera 50 may further include a processor 53, where the processor 53 may be configured to invoke the communication module 52, and transmit the video image of the supplementary lighting scene output by the imaging module 51 to the terminal device 70, so that the terminal device 70 performs a supplementary lighting position visualization process on the video image.

Specifically, in fig. 2 a:

s211: the terminal device 70 may initiate a communication connection with the camera 50, for example, the user may click on the first virtual key 71 triggering the communication connection after selecting the camera 50 as a connected device in a Graphical User Interface (GUI) 700 of the terminal device 70.

S213: the terminal device 70 initiates a request for a visual presentation of the supplementary lighting position, for example, when the communication connection is successfully established, the user may click on the second virtual button 72 for starting the visual presentation in the GUI 700 of the terminal device 70.

S215: the camera 50 can respond to the request of the terminal device, and transmit the video image of the supplementary lighting scene shot by the imaging module 51 to the terminal device 70 by using the communication module 52;

s217: the terminal device 70 may perform a supplementary lighting position visualization process by using a video image of a supplementary lighting scene, so as to perform local highlighting processing on the light spot located in the video image.

S219: terminal device 70 presents the locally highlighted video image (which may also be referred to as a speckle highlight image) on the display screen, for example, the locally highlighted video image may be presented in a video play window 73 of GUI 700.

Referring to fig. 2b, the processor 53 of the camera 50 may be configured to perform a process of visualizing the supplementary lighting position of the video image, so as to perform local highlighting processing on the light spot located in the video image, and the processor 53 may be further configured to invoke the communication module 52 to transmit the video image after the local highlighting processing to the terminal device 70.

Specifically, in fig. 2 b:

s221: the terminal device 70 may initiate a communication connection with the camera 50, e.g. the user may click on the first virtual key 71 triggering the communication connection after selecting the camera 50 as a connected device in the GUI 700 of the terminal device 70.

S223: the terminal device 70 initiates a request for a visual presentation of the supplementary lighting position, for example, when the communication connection is established successfully, the user may click on the second virtual button 72 for starting the visual presentation in the GUI 700 of the terminal device 70.

S225: the camera 50 may respond to a request of the terminal device, and execute a supplementary lighting position visualization process by using a video image of a supplementary lighting scene shot by the imaging module 51, so as to execute a local highlighting process on a light spot positioned in the video image.

S227: the camera 50 transmits the video image after the local highlighting process (which may also be referred to as a spot highlighting image) to the terminal device 70 by using the communication module 52.

S229: terminal device 70 presents the partially highlighted video image on the display screen, e.g., the video image received by terminal device 70 may be presented in video play window 73 of GUI 700.

Based on above-mentioned mutual flow, can be with the help of the virtual facula that presents in visual ground of the video image that obtains to the scene shooting of light filling to help the discernment to the actual projection position of light filling lamp, and, compare in the actual facula that easily receives external light to disturb, the facula coverage area's that presents in visual mode in the video image degree of discernment is higher.

As can also be seen from fig. 2a and fig. 2b, the supplementary lighting position visualization processing procedure executed in S217 and S225 may specifically include:

s231: and acquiring a video image of the supplementary lighting scene.

S232: and positioning the light spot of the fill-in light lamp in the fill-in light scene in the acquired video image according to pre-configured image coordinates, wherein the pre-configured image coordinates are determined according to a relative position relationship between a lens optical axis of the camera and an irradiation optical axis of the fill-in light lamp (for example, a relative position relationship within a range H0 shown in fig. 1).

For example, the center position of the spot in the video image may be determined from pre-configured image coordinates.

For another example, the center position of the light spot in the video image may be determined according to a preset image coordinate, and the edge profile of the light spot in the video image may be further determined according to the center position of the light spot in the video image and a preset light spot size, where the preset light spot size may be estimated by a light source distribution area of a light-emitting lamp surface of the fill-in lamp, a light beam angle of the fill-in lamp, and a lens imaging magnification of a camera that images the video image.

S233: and performing local highlighting processing on the video image positioned to the light spot to enable the light spot coverage area to have higher visual significance than other areas when the video image is visually presented.

For example, the local highlighting processing performed on the video image may be implemented based on adding a visual marker, or may also be implemented by weakening a non-spot area.

The visual mark added to the light spot coverage area in the video image can comprise a first visual mark for identifying the center of the light spot and/or a second visual mark for identifying the outline of the light spot.

The visual saliency of other areas except the light spot coverage area in the video image is weakened, and the light spot coverage area can be enabled to have higher visual saliency than other areas when the video image is visually presented.

Fig. 3a to 3c are schematic diagrams of a first highlighted example of a fill light position visualization process in the interaction flow shown in fig. 2a and 2 b. Referring first to fig. 3a, a first visual marker 601, such as a cross-shaped icon, identifying the center of the spot may be added to the video image 600. Referring again to fig. 3b, a second visual marker 602, such as a circle icon, identifying the outline of the spot may also be added to the video image 600. With continued reference to fig. 3c, a first visual identifier 601 and a second visual identifier 602 may also be added to the video image 600.

Fig. 4 is a schematic diagram of a second highlighting example of a fill light position visualization processing procedure in the interaction flow shown in fig. 2a and 2 b. Referring to fig. 4, in order to weaken the visual saliency of the other regions of the video image except for the light spot coverage area, S233 may crop out the other regions of the video image 600 except for the light spot coverage area 610. Shown in fig. 4 are a cropped line 620 circumscribing the spot coverage area 610 and a spot relief image 630 cropped along the cropped line 620.

Fig. 5 is a schematic diagram of a third highlighting example of a fill-in light position visualization processing procedure in the interaction flow shown in fig. 2a and 2 b. Referring to fig. 5, in order to weaken the visual saliency of other areas except for the light spot coverage area in the video image, S233 may also generate a zoom adjustment signal for a lens of a camera that captured the video image, so that the light spot coverage area 610 may be maximally filled in the video image to obtain the light spot highlight image 640.

Fig. 6 is a schematic diagram of a fourth highlighting example of a fill light position visualization processing procedure in the interaction flow shown in fig. 2a and 2 b. Referring to fig. 10, in order to weaken the visual saliency of other regions in the video image except for the spot coverage region, S233 may further generate a mask 650, the mask 650 having the same size as the video image 600, and the mask 650 may have a window 660 coinciding with the position of the spot coverage region 610, and S233 may add the generated mask 640 to the video image 600 to obtain a spot highlight image 670.

The light supplementing position visualization mode can be suitable for light spot virtualization presentation of an infrared light supplementing lamp, a visible light supplementing lamp or a combined light supplementing lamp of infrared light and visible light. Moreover, because the light spot video acquisition device 40 is detachable, the light supplement lamp 30 and the light spot video acquisition device 40 are combined in a one-to-one manner, so that a plurality of light supplement lamps 30 share one light spot video acquisition device 40.

Additionally, the camera 50 may also include a non-transitory computer readable storage medium 54 for storing instructions that, when executed by the processor 53, may cause the processor 53 to process as previously described.

Above, be the assembly principle to the light filling module, facula video acquisition device 40's theory of operation and the visual principle's in facula position summary that this assembly principle and theory of operation can support.

In order to better understand the assembly principle of the fill light module, the following structure of the embodiment is described in detail.

Alternatively, the holding member 60 may detachably mount the camera 50 to the light-transmitting cover 33 of the fill light 30 covering the light exit surface 300.

Since the light-transmitting cover 33 has few structural features, as described above, the light-transmitting cover 33 may have a smooth shape, and thus, for the light supplement lamps 30 with different body forms, the shape of the light-transmitting cover 33 has a certain commonality, for example, the light-transmitting cover 33 may have a flat shape, or the light-transmitting cover 33 may have an end face shape that is partially flat in the middle region and partially curved in the edge region. Therefore, the assembly scheme in which the camera 50 is mounted on the transparent cover 33 can be considered to be versatile for the fill-in lamp 30 having different body forms.

Accordingly, hereinafter, with respect to an example structure in which the camera 50 is mounted on the transparent cover 33, two types of fill-in lamps 81 and 82 are used to embody different body forms of the fill-in lamp 30.

Fig. 7a and 7b are schematic exploded views of a first example structure of the light supplement module shown in fig. 1.

As can be seen from fig. 7a, the light supplement lamp 81 is a suspended light supplement lamp for being mounted on a column, a lamp body housing 811 of the light supplement lamp 81 can be mounted at one end of the suspended support 816 through a rotating shaft 815, and a clamp 817 for being mounted on the column is disposed at the other end of the suspended support 816, so that the lamp body housing 811 of the light supplement lamp 81 can swing relative to the suspended support 816 through rotation of the rotating shaft 815 to adjust an angle of the transparent lampshade 813, thereby achieving adjustment of a light supplement irradiation position. In addition, the fill light 81 further has an auxiliary bracket 818 rotatably engaged with the rotating shaft 815.

As can be seen from fig. 7b, the light supplement lamp 82 is a base type light supplement lamp with a base, the lamp body housing 821 of the light supplement lamp 82 can be installed on the rotating support frame 825, and the rotating support frame 825 and the base 826 can be rotatably connected through a rotating shaft 827, so that the lamp body housing 821 of the light supplement lamp 82 can swing relative to the base 826 through rotation of the rotating shaft 817 to adjust an angle of the light-transmitting lampshade 823, and thus adjustment of a light supplement irradiation position is achieved. In addition, the rotational support frame 825 of the fill light 82 is engaged with the base 826 by a guiding locking mechanism 828 to support the light body housing 821 at a selected angle relative to the base 826.

In the first example structure shown in fig. 7a and 7b, the holding member 61 may bond the camera 50 to the light-transmissive cover 813 of the fill light 81 or the light-transmissive cover 823 of the fill light 82. At this time, the lens 500 of the camera 50 is arranged in the same direction as the irradiation direction of the fill-in lamp 81, and the optical axis of the lens 500 is parallel to the irradiation optical axis of the fill-in lamp 30.

In particular, the holding member 61 may comprise a viscous medium. For example, the viscous medium may be a flexible pad coated on both sides with a layer of washable glue (e.g., water washable glue), or may be a muddy sticky substance in an unfixed form, or may be a back glue.

Fig. 8a and 8b are schematic diagrams illustrating an example of centering assembly of the first example structure of the light supplement module shown in fig. 1. Referring to fig. 8a and 8b, the camera 50 may be adhered to the center of the transparent cover 813 of the fill light 81 or the transparent cover 823 of the fill light 82 by the holding member 61.

At this time, the optical axis of the lens 500 of the camera 50 may coincide with the irradiation optical axis of the fill-in lamp 81 or 82.

Accordingly, in S232 as shown in fig. 2a and 2b, the center coordinates of the pre-configured video image may be determined as the center position of the light spot.

Fig. 9a and 9b are schematic diagrams illustrating an offset assembly example of the first example structure of the light filling module shown in fig. 1. Referring to fig. 9a and 9b, the camera 50 may be bonded to the light-transmitting cover 813 of the fill light 81 or the light-transmitting cover 823 of the fill light 82 by the holding member 61, and the bonding position may be a shift position having a predetermined shift in a prescribed direction with respect to the center position of the light-transmitting cover 823.

At this time, the optical axis of the lens 500 of the camera 50 may have a spatial offset amount E11 or E21 in a specified direction with respect to the irradiation optical axis of the fill-in lamp 81 or 82.

Accordingly, in S232 shown in fig. 2a and 2b, a previously configured offset coordinate of the video image, which has a set offset amount in a specified direction with respect to the center coordinate of the video image, may be determined as the center position of the light spot, and the set offset amount may be determined according to the spatial offset amount E11 or E21 of the lens optical axis of the camera 50 with respect to the irradiation optical axis of the fill-in lamp 81 or 82, and the lens imaging magnification of the camera 50.

Fig. 10a and 10b are schematic exploded views of a second exemplary structure of the light supplement module shown in fig. 1. In the second example structure shown in fig. 10a and 10b, the holding member 62 may be attached to the light-transmitting cover 813 of the fill light 81 or the light-transmitting cover 823 of the fill light 82.

Fig. 11a and 11b are schematic structural diagrams of a holding member used in a second example structure of the light supplement module shown in fig. 1. Referring to fig. 11a and 11b, the holding member 62 in the second example structure may include a mounting frame 621, a supporting member 622, and an adsorption member 623 having a surface adsorption capability, such as a suction cup.

The mounting frame 621 has a lens window 620, the supporting member 622 is mounted on the mounting frame 621, and the suction member 623 is mounted on an end of the supporting member 622.

When the adsorption member 623 is adsorbed to the

light transmitting cover

813 or 823, the support member 622 may form a mounting space between the mounting frame 621 and the

light transmitting cover

813 or 823, and the camera 50 may be pressed into the mounting space formed between the mounting frame 621 and the

light transmitting cover

813 or 823, and at the same time, the lens 500 of the camera 50 may be exposed at the lens window 620 of the mounting frame 621. At this time, the lens 500 of the camera 50 is disposed in the same direction as the irradiation direction of the fill-in lamp 81 or 82, and the optical axis of the lens 500 is parallel to the irradiation optical axis of the fill-in lamp 81 or 82.

In addition, the holding member 62 in the second example structure may further include an elastic element 624, the elastic element 624 may be mounted to the supporting member 622, and the elastic element 624 may generate an elastic pressing force that presses the mounting frame 621 toward the light-transmitting

cover

813 or 823.

For example, the mounting frame 621 may have a frame main body 621a and frame ears 621b, wherein the lens window 620 is opened in the frame main body 621a, and the frame ears 621b may be formed on the outer side of the frame main body 621a, for example, the frame ears 621b may be formed in pairs on the opposite outer sides of the frame main body 621 a; the supporting member 622 may be inserted into the frame ears 621b, wherein one end of the supporting member 622 may fix the absorbing member 623, the other end of the supporting member 622 may be provided with a limiting element 625, and the elastic element 624 may be elastically pressed between the limiting element 625 and the frame ears 621b to generate an elastic pressing force on the frame ears 621b to press the mounting frame 621 towards the

transparent lamp cover

813 or 823.

The supporting member 622 may include a stud, the suction member 623 may include a suction cup and a screw fixed to the suction cup and screw-engaged with one end of the stud, the position-limiting element 625 may be a screw-engaged with the other end of the screw, and the elastic element 624 may be a spring fitted over the stud, so that a cap of the screw serving as the position-limiting element 625 may limit the spring serving as the elastic element 624 to press the spring limit serving as the elastic element 624 between the cap and the frame lug 621 b.

Fig. 12a and 12b are schematic diagrams illustrating an example of centering assembly of the second example structure of the light supplement module shown in fig. 1. Referring to fig. 12a and 12b, the camera 50 may be adhered to the center of the transparent cover 813 of the fill light 81 or the transparent cover 823 of the fill light 82 by the holding member 62.

Fig. 13a and 13b are schematic diagrams illustrating an offset assembly example of the second example structure of the fill light module shown in fig. 1. Referring to fig. 13a and 13b, the camera 50 may be bonded to the light-transmitting cover 813 of the fill light 81 or the light-transmitting cover 823 of the fill light 82 by the holding member 62, and the bonding position may be a shift position having a predetermined shift in a prescribed direction with respect to the center position of the light-transmitting cover 823.

At this time, the optical axis of the lens 500 of the camera 50 may have a spatial offset E12 or E22 in a specified direction with respect to the irradiation optical axis of the fill light 81 or 82.

Accordingly, in S232 shown in fig. 2a and 2b, the offset coordinate of the pre-configured video image may be determined as the center position of the light spot, the offset coordinate having a set offset amount in a specified direction with respect to the center coordinate of the video image, and the set offset amount may be determined according to the spatial offset amount E12 or E22 of the lens optical axis of the camera 50 with respect to the irradiation optical axis of the fill-in lamp 81 or 82, and the lens imaging magnification of the camera 50.

As can be seen from the above, the installation position of the camera 50 on the

transparent lamp shade

813 or 823 needs to match the configuration coordinates of the video image used for performing the fill light position visualization processing as much as possible, and the matching degree of the installation position and the configuration coordinates may affect the accuracy of the visual presentation of the spot position.

To this end, the light-transmitting

lamp cover

813 or 823 may be further formed with a positioning guide mechanism for guiding the installation position of the video capture device 40.

Fig. 14a to 14c are schematic views of expanded structures of the first example structure and the second example structure.

Referring to fig. 14a, the positioning and guiding mechanism of the

transparent lamp cover

813 or 823 may include a silk screen groove 831. The screen printing recesses 831 may be configured to match the shape and size of the side of the camera 50 facing the

transparent lampshade

813 or 823. Also, in order to reduce the influence on the refraction uniformity of the light-transmitting

cover

813 or 823, the depth of the silk-screen groove 831 may be much smaller than the thickness of the light-transmitting

cover

813 or 823 and may be recognized by human eyes.

Thus, whether the holding member 61 in the first example structure or the holding member 63 in the second example structure is used, it is possible to help guide the operator to mount the camera 50 at the position where the screen groove 831 is intended to be guide-mounted, that is, at the position matching the configuration coordinates of the video image used to perform the fill-in position visualization process, based on the guidance of the screen groove 831.

Alternatively, referring to fig. 14b, the positioning and guiding mechanism of the

transparent lampshade

813 or 823 may comprise a silk screen rib 832. The border defined by the silk-screen rib 832 may be configured to match the shape and size of the side of the camera 50 facing the

transparent cover

lamp cover

813 or 823, the height of the projection of the silk-screen rib 832 may be much smaller than the thickness of the light-transmitting

lamp cover

813 or 823 and can be recognized by human eyes.

Thus, whether the holding member 61 in the first example structure or the holding member 63 in the second example structure is used, it is possible to help guide the operator to mount the camera 50 at a position where the screen rib 832 is intended to guide the mounting, that is, a position matching the arrangement coordinates of the video image used for performing the fill light position visualization process, based on the guidance of the screen rib 832.

Alternatively, referring to fig. 14c, the positioning and guiding mechanism of the

transparent lampshade

813 or 823 may comprise a blind pin hole 833. The position of the blind pin hole 833 may represent the reference position of the optical axis of the lens 500 of the camera 50. Moreover, the pin blind hole 833 cannot penetrate through the light-transmitting

lampshade

813 or 823, so that the waterproof performance of the light-transmitting

lampshade

813 or 823 is not damaged. Preferably, the depth of the blind pin hole 833 can be less than half the thickness of the light-

transmissive lamp shade

813 or 823.

Accordingly, the side of the camera 50 facing the light-

transmissive lamp shade

813 or 823 may be provided with a positioning pin, the length of which may not exceed the depth of the pin blind hole 833, and, for the first example structure, should also be greater than the thickness of the holding member 61.

Thus, whether the holding member 61 in the first example structure or the holding member 63 in the second example structure is used, guidance based on the fitting of the positioning pin with the blind needle hole 833 can help guide the operator to mount the camera 50 at a position where the blind needle hole 833 is intended to be guide-mounted, that is, a position matching the arrangement coordinates of the video image used for performing the fill light position visualization process.

The holding member 60 may detachably mount the camera 50 to the lamp body housing 31 of the light supplement lamp 30, in addition to detachably mounting the camera 50 to the light-transmitting cover 33 of the light supplement lamp 30.

Fig. 15 is an assembly state diagram of a third example structure of the light supplement module shown in fig. 1. Referring to fig. 15, taking a light supplement lamp 82 in a seat form as an example, the holding member 63 may be fastened to a lamp body housing 821 of the light supplement lamp 82, and may support the camera 50 outside the lamp body housing 821 (e.g., above the lamp body housing 821).

At this time, the optical axis of the lens 500 of the camera 50 may have a spatial offset E23 in a predetermined direction with respect to the irradiation optical axis of the fill-in lamp 82.

Specifically, the holding member 63 may include a support beam 631, a mounting frame 632, and a clamp arm 633.

The mounting frame 632 is fixed to (e.g., integrally formed with) one side (e.g., an upper side) of the support beam 631, and the mounting frame 632 is provided with a locking groove 630. For example, the mounting frame 632 may be integrally formed at a middle position in the length direction of the support beam 631.

The clamp arms 633 may be mounted in pairs to the support beam 631, and the clamp arms 633 protrude from the support beam 631 on the other side (e.g., lower side) opposite to the mounting frame 632. For example, the clamp arms 633 may be disposed on opposite sides of the mounting frame 632, respectively.

The holding arms 633 form a holding space for holding the lamp housing 821.

Preferably, the clamping arms 633 may be slidably engaged with the support beam 631 to provide a dimensionally adjustable clamping spacing, and the clamping arms 633 may further be provided with locking elements 634 to lock the clamping spacing at a selected size. Thus, the holding member 63 may be common to fill lamps of different forms, that is, the third example structure is not limited to the pedestal-type fill lamp 82.

The camera 50 may be snapped into the snap groove 630 of the mounting frame 632. Accordingly, the lens 500 of the camera 50 is arranged in the same direction as the irradiation direction of the fill-in lamp 82, and the optical axis of the lens 500 is parallel to the irradiation optical axis of the fill-in lamp 82.

In addition, the support beam 631 may have a pre-installation positioning groove 635, wherein the pre-installation positioning groove 635 may be aligned with the mounting frame 632, and the pre-installation positioning groove 635 may match the shape of a protrusion on the circumferential surface of the lamp housing 821 (the outer arc surface of the cylindrical lamp housing 821).

Thus, the pre-assembly positioning slots 635 may pre-assemble the stabilizing support beam 631 to the curved lamp housing 821 before the clamping arms 633 form a clamp on the lamp housing 821.

In order to match the mounting position with the configuration coordinates to ensure accuracy in visual presentation of the spot position, the lamp body housing 821 in the third example structure may also be further formed with a positioning guide mechanism for guiding the installation position of the video capture device 40.

Fig. 16a and 16b are schematic views of an expanded structure of the third example structure incorporating the installation guiding function.

Referring to fig. 16a, the lamp body 821 can further form a reference mark 834 such as a scale to guide the operator to align the camera 50 clamped on the mounting frame 632 with the reference mark 834.

Referring to fig. 16b, the lamp body 821 may further form a positioning protrusion 835, and the support beam 631 may further have a positioning notch 636 engaged with the positioning protrusion 835.

Thereby, it is possible to help guide the operator to mount the camera 50 at a position where the reference position mark 834 or the positioning boss 835 is intended to guide the mounting, that is, at a position matching the configuration coordinates of the video image used for performing the supplementary light position visualization process.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like made within the spirit and principle of the present invention should be included in the scope of the present invention.
