[0065] Embodiments of the present disclosure provide a method, a device, and a supplementary lighting device for determining the installation position of a lighting device.

[0073] It should be understood that Figure 1 the numbers of terminal devices, networks, and servers in

[0074] are merely illustrative. According to the implementation requirements, there can be any number of terminal devices, networks, and servers. Figure 1 The following will be based on Figures 2 to 6 the described scenario and will describe in detail the method for determining the installation position of the lighting device in the disclosed embodiments through

[0075] Figure 2 FIG. schematically shows a flowchart of the method for determining the installation position of the lighting device according to an embodiment of the present disclosure.

[0076] As Figure 2 shown, the method for determining the installation position of the lighting device in this embodiment includes operation S210 to operation S230.

[0077] In operation S210, according to the respective light illumination property information of the lighting devices in the multiple lighting arrays and the positional relationship of the lighting devices relative to the reference plane, determine the initial light field energy distribution information of the multiple lighting arrays on the reference plane, wherein the multiple lighting arrays are symmetric with respect to a calibration point, and for the multiple lighting arrays, the lighting devices with a symmetric positional relationship in the initial installation positions of the lighting devices are used as symmetric lighting tuples.

[0078] According to an embodiment of the present disclosure, the lighting device may include an element, a device, etc. that can emit light, such as an LED lamp, etc. The embodiment of the present disclosure does not limit the specific type of the lighting device, and those skilled in the art can select according to actual needs as long as the reference plane can be illuminated.

[0079] According to an embodiment of the present disclosure, the light illumination property information may include the property information of the light rays emitted by the lighting device or the lighting array, such as the irradiation angle of the light rays, the light intensity, etc. The embodiment of the present disclosure does not limit the specific type of the light illumination property information.

[0080] According to an embodiment of the present disclosure, the lighting array may be obtained by arranging lighting devices in an array form, and the dimension of the lighting array may be one-dimensional or multi-dimensional. The embodiment of the present disclosure does not limit the dimension of the lighting array, and those skilled in the art can select according to actual needs.

[0081] According to an embodiment of the present disclosure, the calibration point may be set at any position in space. For example, it may be set in the plane formed by the lighting array, or may also be set in the plane where the reference plane is located, or may also be set in the space in the light emitting direction of the lighting device, or may also be set on the relative back side of the light emitting direction of the lighting device. Those skilled in the art can set the specific position of the calibration point according to actual needs, and the embodiment of the present disclosure does not limit this.

[0082] According to an embodiment of the present disclosure, the lighting tuple may be a group of lighting devices that are symmetric with respect to the calibration point. The embodiment of the present disclosure does not limit the number of lighting devices in the lighting tuple.

[0083] In operation S220, according to the comparison result between the abnormal light field energy distribution information in the initial light field energy distribution information and the light field energy threshold, update the respective initial installation positions of the lighting devices in the symmetric lighting tuple according to the adjustment distance to obtain multiple candidate lighting arrays.

[0084] According to an embodiment of the present disclosure, the initial light field energy distribution information may be the light intensity (optical intensity) distribution received by the illuminated area of the reference surface when the illumination array irradiates the reference surface, or when the light rays emitted by the simulated illumination array irradiate the reference surface. In the initial light field energy distribution information, the distribution information that significantly deviates from the reference light field energy value may be abnormal light field energy distribution information. For example, when the light field energy distribution in the middle area of the initial light field energy distribution information is much larger than the reference light field energy value, this middle area may be the abnormal light field energy distribution information of the initial light field energy distribution information.

[0085] It should be noted that the light field energy threshold may be a specific value or a numerical range, and the embodiments of the present disclosure do not limit the specific type of the light field energy threshold.

[0086] In operation S230, according to the respective light attribute information of the lighting devices in the multiple candidate illumination arrays and the positional relationship of the lighting devices in the candidate illumination arrays relative to the reference surface, determine the candidate light field energy distribution information of the multiple candidate illumination arrays on the reference surface.

[0087] In operation S240, when the abnormal light field energy distribution information in the candidate light field energy distribution information satisfies the light field energy range corresponding to the light field energy threshold, determine the candidate installation positions of the lighting devices in the candidate illumination array as the target installation positions.

[0088] According to an embodiment of the present disclosure, the frequency of updating the initial installation positions of the lighting devices may be once or multiple times, and the embodiments of the present disclosure do not limit the number of frequencies of obtaining the target installation positions through updating.

[0089] It should be noted that any method in the related art can be used to determine the target installation position. For example, the target installation position can be obtained by fitting based on the fitting algorithm in the related art, such as the least squares method. Alternatively, the loss function can also be used to process the abnormal light field distribution information and the light field energy threshold in the candidate light field distribution information until the loss function converges, that is, when the abnormal light field energy distribution information satisfies the light field energy range corresponding to the light field energy threshold, determine the corresponding candidate installation position as the target installation position.

[0090] According to an embodiment of the present disclosure, the light field energy threshold can be determined by the upper light field energy value or the lower light field energy value of the light field energy range, or it can also be determined according to the actual needs of those skilled in the art. The embodiments of the present disclosure do not limit the specific determination method of the light field energy threshold, and those skilled in the art can choose according to actual needs.

[0091] According to an embodiment of the present disclosure, by calculating the initial light field energy distribution information of the lighting devices in the lighting array on the reference plane, and then updating the initial installation positions of the lighting devices based on the comparison result between the abnormal light field energy distribution information in the initial light field energy distribution information and the light field energy threshold, it can be ensured that in the candidate light field energy distribution information formed by the lighting array on the candidate installation positions obtained by the update, when the abnormal light field energy distribution information satisfies the light field energy range corresponding to the light field energy threshold, the lighting devices at the target installation positions can form a more uniform light field distribution on the reference plane, improving the lighting uniformity of the lighting devices. Furthermore, when using the lighting devices to supplement light for an image acquisition device, the technical problem of overexposure in the captured images can be avoided, achieving the technical effect of improving the quality of image acquisition.

[0092] According to an embodiment of the present disclosure, the symmetry between multiple lighting arrays with respect to a calibration point may include:

[0093] Multiple lighting arrays are centrosymmetric with respect to the calibration point; or multiple lighting arrays are axially symmetric with respect to the calibration point.

[0094] It should be understood that when multiple lighting arrays are centrosymmetric with respect to the calibration point, the multiple lighting devices in the symmetric lighting tuple are centrosymmetric with respect to the calibration point. When multiple lighting arrays are axially symmetric with respect to the calibration point, the multiple lighting devices in the symmetric lighting tuple are axially symmetric with respect to the calibration point.

[0095] According to an embodiment of the present disclosure, there are multiple initial installation distances between adjacent illumination devices in the lighting array.

[0096] The multiple initial installation distances in the lighting array gradually increase along the arrangement direction from far to near the calibration point.

[0097] According to an embodiment of the present disclosure, when the light illumination attribute information of each illumination device in the lighting array is the same, by setting the initial installation positions of the illumination devices in the same illumination array in a gradually sparser manner in the direction towards the calibration point, the deviation degree of the abnormal light field energy distribution information in the initial light field energy distribution information with respect to the light field energy threshold can be reduced, thereby reducing the frequency of subsequent adjustments to obtain the target installation positions and improving the overall efficiency of determining the target installation positions.

[0098] According to an embodiment of the present disclosure, the light illumination attribute information includes the light irradiation angle and the initial light intensity, and the positional relationship includes the distance from the lighting device to the reference plane.

[0099] Figure 3A flowchart is schematically shown for determining the initial light field energy distribution information of a plurality of lighting arrays on a reference plane based on the respective light illumination attribute information of the lighting devices in the plurality of lighting arrays and the positional relationship of the lighting devices relative to the reference plane according to an embodiment of the present disclosure.

[0100] As Figure 3 shown, in operation S210, determining the initial light field energy distribution information of the plurality of lighting arrays on the reference plane based on the respective light illumination attribute information of the lighting devices in the plurality of lighting arrays and the positional relationship of the lighting devices relative to the reference plane may include operations S310 to S340.

[0101] In operation S310, based on the respective light irradiation angles of the lighting devices and the distances from the lighting devices to the reference plane, determine the initial light illumination regions corresponding to the lighting devices on the reference plane, and the light irradiation distances between the lighting devices and the irradiated points in the initial light illumination regions.

[0102] In operation S320, based on the initial light illumination intensity of the lighting device and the light irradiation distance, determine the initial light illumination energy of the lighting device at the irradiated point.

[0103] In operation S330, calculate the initial cumulative light illumination energy of the irradiated point based on the initial light illumination energies of the irradiation devices associated with the irradiated point in the plurality of lighting arrays at the irradiated point.

[0104] In operation S340, determine the initial light field energy distribution information based on the initial cumulative light illumination energy of the irradiated point and the positional relationship between the irradiated point and the reference plane.

[0105] According to an embodiment of the present disclosure, the initial light illumination intensity may include the initial light intensity of the light rays emitted by the lighting device. It should be understood that the initial light illumination intensity may decrease as the light irradiation distance increases. Correspondingly, the different light irradiation distances between the irradiated points in the reference plane and the irradiation devices may cause the irradiated points to generate corresponding light illumination energies.

[0106] According to an embodiment of the present disclosure, the lighting device includes a light-emitting element and a lamp shade sleeved outside the light-emitting element.

[0107] The above method for determining the installation position of the lighting device may further include: determining the light irradiation angle of the lighting device according to the shape of the lamp shade.

[0108] Figure 4 A schematic diagram is schematically shown for determining the initial light illumination energy of the irradiated point according to an embodiment of the present disclosure.

[0109] As Figure 4As shown, the light irradiation angle of the lighting device 410 can be 2α, and the distance between the lighting device 410 and the reference plane can be h. Accordingly, the light emitted by the lighting device 410 can irradiate on the reference plane, thereby forming an irradiated area 420 on the reference plane. The irradiated area 420 can be simulated as a circular area with a radius of r on the reference plane.

[0110] The irradiated point 421 of the irradiated area 420 can be located at the edge of the circular area. Accordingly, the initial cumulative light energy of the irradiated point 421 can be calculated by the following formula.

[0111] P xy = P0·k h ·f(α); (1)

[0112] In formula (1), P xy represents the initial cumulative light energy of the irradiated point 421, P0 represents the initial light intensity of the lighting device 410, k h represents the light intensity attenuation coefficient, and f(α) can represent the position relationship function between the initial light intensity of the lighting device 410 and the light irradiation angle a. This position relationship function can be obtained by fitting the coordinates of the irradiated point in the reference plane.

[0113] For example, in the case where the center point 422 of the irradiated area 420 is the coordinate origin, the coordinates of the irradiated point 421 can be represented as (x, y). Through the following formulas (2) and (3), the position relationship function can be determined.

[0114] x = r·cos(θ) = h·tan(α)·cos(θ);(2)

[0115] y = r·sin(θ) = h·tan(α)·sin(θ); (3) [[ID=2,8]]

[0116] Therefore, by combining formulas (1) to (3), the initial light energy of each irradiated point on the reference plane relative to one lighting device can be determined. Then, by adding up the initial light energies generated by each irradiated point for different irradiation devices respectively, the initial cumulative light energy of the irradiated point can be obtained. For example, the initial cumulative light energy can be determined by formula (4).

[0117] P xy ’ = ∑P xy (i) i = 1, 2, 3..., n; (4)

[0118] In formula (4), P xy ’ represents the initial cumulative light energy of the irradiated point, and n represents the number of irradiation devices.

[0119] It should be understood that after obtaining the initial cumulative illumination energy of each illuminated point on the reference plane, the initial light field energy distribution information, such as the light field energy distribution curve, can be correspondingly obtained according to the coordinates of the illuminated point relative to the reference plane.

[0120] According to an embodiment of the present disclosure, the reference plane is parallel to the illumination plane formed by a plurality of illumination arrays, the calibration point is located in the illumination plane, and the abnormal light field energy distribution information includes the mapped point illumination energy of the mapped point, where the mapped point is obtained after being mapped to the reference plane through the calibration point.

[0121] The method for determining the installation position of the lighting device in this embodiment further includes:

[0122] Determine the mapped point illumination energy of the mapped point according to the initial light field energy distribution information.

[0123] In operation S220, according to the comparison result between the abnormal light field energy distribution information in the initial light field energy distribution information and the light field energy threshold, updating the respective initial installation positions of the lighting devices in the symmetric lighting tuple according to the adjustment distance may include the following operations:

[0124] Compare the mapped point illumination energy with the light field energy threshold to obtain a comparison result; in the case where the comparison result indicates that the mapped point illumination energy is greater than the light field energy threshold, move the lighting devices in the symmetric lighting tuple along the first direction close to the calibration point by the adjustment distance respectively to obtain the respective candidate installation positions of the lighting devices in the symmetric lighting tuple; and construct a plurality of candidate illumination arrays according to the respective candidate installation positions of the lighting devices in the symmetric lighting tuple.

[0125] According to an embodiment of the present disclosure, when the initial light field energy distribution information is a light field energy distribution curve, the mapped point illumination energy may be the light field energy at the center point of the light field energy distribution curve. When the plurality of illumination arrays are symmetric with respect to the calibration point, the mapped point illumination energy can characterize the deviation degree of the light field energy distribution curve with respect to the light field energy threshold. Therefore, in the case where the comparison result indicates that the mapped point illumination energy is greater than the light field energy threshold, along the first direction close to the calibration point according to the preset movement adjustment distance or the dynamically calculated movement adjustment distance, the lighting devices in the symmetric lighting tuple can reduce the deviation degree of the candidate light field energy distribution information irradiated on the reference plane by the candidate illumination arrays set at the candidate installation positions, that is, the mapped point illumination energy is closer to the light field energy threshold, and thus the candidate light field energy distribution information is more uniform.

[0126] It should be understood that in the case where there are multiple symmetric lighting tuples, the lighting devices in any number of symmetric lighting tuples can be moved, and the embodiment of the present disclosure does not limit the number of symmetric lighting tuples that need to be moved.

[0127] According to an embodiment of the present disclosure, the operation of updating the initial installation positions of the lighting devices in the above symmetric lighting tuple can be iteratively performed multiple times. That is, after obtaining the current candidate lighting array, the comparison result between the mapped point illumination energy corresponding to the current candidate lighting array and the light field energy threshold can be iteratively determined until the mapped point illumination energy satisfies the light field energy range corresponding to the light field energy threshold, and the corresponding target installation position is obtained.

[0128] According to an embodiment of the present disclosure, there are multiple symmetric lighting tuples, and the multiple symmetric lighting tuples include a target symmetric lighting tuple.

[0129] In the above operation, moving and adjusting the distances of the lighting devices in the symmetric lighting tuple along the first direction close to the calibration point respectively may include the following operations:

[0130] Move and adjust the distances of the target lighting devices in the target symmetric lighting tuple along the first direction close to the calibration point respectively, to obtain the candidate installation positions of the target lighting devices in the target symmetric lighting tuple.

[0131] According to an embodiment of the present disclosure, the target symmetric lighting tuple can be determined by a preset method, or can also be determined based on other methods, such as by a random setting method. The embodiments of the present disclosure do not limit the specific method for determining the target symmetric lighting tuple, and those skilled in the art can select according to actual needs.

[0132] According to an embodiment of the present disclosure, the target symmetric lighting tuple can be selected through a prediction model constructed based on a machine learning algorithm, so as to improve the overall determination of the target installation position and realize the portability and accuracy of the design of the target installation position.

[0133] According to an embodiment of the present disclosure, according to the comparison result between the abnormal light field energy distribution information in the initial light field energy distribution information and the light field energy threshold, updating the initial installation positions of the lighting devices in the symmetric lighting tuple according to the adjustment distance further includes the following operations:

[0134] Compare the mapped point illumination energy with the light field energy threshold to obtain a comparison result; in the case where the comparison result indicates that the mapped point illumination energy is less than the light field energy threshold, move and adjust the distances of the lighting devices in the symmetric lighting tuple along the second direction away from the calibration point respectively, to obtain the candidate installation positions of the lighting devices in the symmetric lighting tuple; and construct multiple candidate lighting arrays according to the candidate installation positions of the lighting devices in the symmetric lighting tuple.

[0135] It should be noted that the light field energy threshold can be determined by the upper light field energy value and / or the lower light field energy value of the light field energy range, so as to accurately determine the target installation position.

[0136] According to an embodiment of the present disclosure, a plurality of symmetric illumination tuples are included, and the plurality of symmetric illumination tuples include a target symmetric illumination tuple.

[0137] In the above operation, moving the illumination devices in the symmetric illumination tuple along the second direction away from the calibration point to adjust the distance may include the following operations:

[0138] Move the target illumination devices in the target symmetric illumination tuple along the second direction away from the calibration point to adjust the distance, and obtain the candidate installation positions of the target illumination devices in the target symmetric illumination tuple respectively.

[0139] Figure 5 Schematically shows a schematic diagram of the illumination device disposed at the initial installation position according to an embodiment of the present disclosure.

[0140] Figure 6 Schematically shows a schematic diagram of the initial light field energy distribution information according to an embodiment of the present disclosure.

[0141] Combined with Figure 5 and Figure 6 As shown, the illumination devices 521, 522, 531, 532, 541 and 542 can be respectively disposed at their respective initial installation positions. Among them, the illumination devices 521, 531 and 541 form an illumination array, and the illumination devices 522, 532 and 542 form an illumination array. The two illumination arrays are symmetric with respect to the calibration point 511. The initial installation distances between the illumination devices 521, 531 and 541 in the illumination array gradually increase along the arrangement direction from far to near the calibration point 511, that is, along the calibration point 511, the initial installation distances are gradually sparse. The symmetric illumination tuple may include a first symmetric illumination tuple composed of the illumination devices 521 and 522, a second symmetric illumination tuple composed of the illumination devices 531 and 532, and a third symmetric illumination tuple composed of the illumination devices 541 and 542.

[0142] According to the respective initial installation positions of the illumination devices 521, 522, 531, 532, 541 and 542, the respective light illumination attribute information of the illumination devices 521, 522, 531, 532, 541 and 542, and the positional relationship between the initial installation position and the reference plane, the initial light field energy distribution information 610 of the reference plane can be calculated. The light field energy distribution information 610 may be a light field energy distribution curve.

[0143] It should be noted that Figure 6In the coordinate system corresponding to the mid-light field energy distribution information 610, the horizontal axis is the coordinate position of the reference plane, and the vertical axis can be the illumination energy value. The mid-light field energy distribution information 610 may include abnormal energy distribution information 611 (abnormal energy distribution curve), and the abnormal energy distribution information 611 may include the illumination energy 6111 of the mapping point. The illumination energy 6111 of the mapping point may be the initial cumulative illumination energy corresponding to the mapping point formed by mapping the calibration point 511 to the reference plane.

[0144] According to an embodiment of the present disclosure, when the illumination energy 6111 of the mapping point is greater than the light field energy threshold, for example, when the illumination energy 6111 of the mapping point is greater than the light field energy of the light field energy range 620, the first symmetric illumination element group composed of the illumination devices 521 and 522 can be moved along the first direction, that is, along the direction close to the calibration point 511, by a preset adjustment distance, so that the illumination devices 521 and 522 can be moved to the candidate installation positions, and then the current candidate illumination array can be obtained. Correspondingly, the candidate light field energy distribution information can be obtained according to the current candidate illumination array.

[0145] It should be understood that the illumination energy of the mapping point of the candidate light field energy distribution information can be closer to the light field energy range 620, so that the light field energy distribution curve corresponding to the candidate light field energy distribution information is smoother, indicating that the light field provided by multiple illumination arrays is more uniform.

[0146] When the illumination energy of the mapping point of the current candidate light field energy distribution information is still greater than the light field energy threshold corresponding to the light field energy range 620, the candidate installation positions of the illumination devices in the symmetric illumination element group can be updated based on the same or similar method in the above embodiment until the candidate light field energy distribution information corresponding to the obtained candidate installation position satisfies the light field energy range 620 corresponding to the light field energy threshold, for example, the illumination energy of the mapping point is within the light field energy range 620, and the corresponding target installation position is obtained.

[0147] It should be noted that when the illumination energy of the mapping point of the current candidate light field energy distribution information is less than the light field energy threshold corresponding to the light field energy range 620, for example, less than the lower limit energy value of the light field energy range 620, the illumination devices in the symmetric illumination element group can be moved along the second direction by a preset adjustment distance until the illumination energy of the mapping point of the current candidate light field energy distribution information is within the light field energy range 620, and the corresponding target installation position is obtained.

[0148] It should be understood that during the process of updating the symmetric illumination element group, it can be adjusted Figure 5Any one or more of the first symmetric lighting tuple, the second symmetric lighting tuple, and the third lighting tuple in [it], for example, the first symmetric lighting tuple, the second symmetric lighting tuple, and the third lighting tuple can all be determined as the target symmetric lighting tuple, or the first symmetric lighting tuple and the second symmetric lighting tuple can also be selected as the target symmetric lighting tuple according to actual needs.

[0152] As Figure 7 shown, the lighting device 700 may include lighting devices 711 and a lighting device mounting structure 720. A plurality of lighting devices 711 may be mounted on the target mounting positions of the lighting device mounting structure 720, and the respective target mounting positions of the lighting devices 711 may be obtained by the method for determining the mounting positions of the lighting devices in the above embodiment.

[0153] The lighting device 700 may have two lighting device mounting structures 720. The lighting device mounting structure 720 may be mounted on the fixing member 730 through a rotating mounting member 741 to adjust the irradiation angle of the lighting device 711.
