[0043] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0044] In specific implementation, such as in the construction of highway, railway and water conservancy and hydropower water diversion, water transmission, drainage and other projects, it is usually necessary to build underground caverns in rock strata and / or soil to facilitate the progress of the project. However, during long-term use, the spatial structure of the underground cavern is easily affected by adverse geological conditions, external rock pressure, external water pressure, and the inner wall of the cavern is affected by various natural environmental factors such as water erosion, carbonization and aging, which lead to engineering diseases and defects such as cracking, wear and tear, and water seepage in the structure of the cavern, and there is a construction safety hazard of collapse. Therefore, it is necessary to inspect and evaluate the spatial structure quality of the underground cavern, and carry out targeted maintenance accordingly to eliminate construction safety hazards.

[0045] At present, the inspection and evaluation of the spatial structure quality of underground caverns is carried out by using high-definition cameras, computer vision and other technologies to collect images of underground caverns for surface inspection, and using AI recognition and other technologies to identify diseased or defective objects in the images. However, in actual work, the surface of underground caverns often has uneven and irregular small defects, and different defects will form different light and shadows, and the surface of underground caverns will have a variety of different textures, which will interfere with image acquisition and image recognition, reduce the quality of the acquired images, and reduce the accuracy and reliability of image object recognition.

[0046] In order to improve the quality of the collected images, it is necessary to improve the lighting effect of underground caverns and other places where spatial structure quality detection is required. Based on this, an embodiment of the present application provides a method for controlling a lighting device, by determining the boundary information of the space to be illuminated, and then determining the target lighting area corresponding to the lighting device, and adjusting the control coefficient based on the target lighting area, so that the lighting device can illuminate the target lighting area under the control of the corresponding control coefficient, so that the entire space to be illuminated can obtain uniform lighting, thereby improving the lighting effect of the space to be illuminated, and then improving the quality of image acquisition, and improving the reliability and accuracy of detection and evaluation of the space to be illuminated based on the collected images.

[0047] The following is an exemplary description of the control method, device and terminal device of the lighting device provided in the embodiments of the present application in conjunction with the accompanying drawings:

[0048] See also Figure 1 , Figure 1 A flowchart of a method for controlling a lighting device provided by an embodiment of the present application is shown, which may specifically include the following steps:

[0049] Step 101: determine at least one lighting device for illuminating a space to be illuminated.

[0050] Among them, the lighting device can be a device that can provide a light source. The lighting device can include one or more light-emitting lamp beads or light-emitting panels whose light-emitting parameters can be adjusted arbitrarily. The light-emitting parameters can include one or more parameters such as angle, output power, light intensity, etc. The target lighting area can be the area that needs to be illuminated by the lighting device in the space to be illuminated.

[0051] After determining the space to be illuminated that needs to be illuminated, at least one lighting device used to illuminate the space to be illuminated can be determined. For example, at least one lighting device in the space to be illuminated can be determined, and at least one lighting device that is predicted to enter the space to be illuminated in the future based on historical lighting information over a period of time can also be determined.

[0052] Specifically, the lighting equipment can be in the space to be illuminated, such as being installed on the wall of an underground cavern, or being fixed on the ground of an underground tunnel with a bracket. The lighting equipment can also be set on a movable device, such as being set on a collection vehicle for collecting images. The space to be illuminated can be the space that the movable device will enter in the future and needs to be illuminated.

[0053] In practical applications, the lighting device can be installed on a cylindrical or polygonal lighting fixture, and when performing lighting work, the axis of the lighting fixture can be parallel to the tangent line of the line of the space to be illuminated at the location of the lighting fixture, and the line of the space to be illuminated can be used to represent the straightness and position changes of the space to be illuminated in space. For example, Figure 2a As shown, the axis a1-a1' of the cylindrical lighting fixture A can be parallel to the tangent c1-c1' of the alignment direction of the space to be illuminated at the location of the lighting fixture A, wherein Figure 2b As shown, the tangent line of the line b1-b1' of the space to be illuminated at the location of the lighting fixture A may be c1-c1'.

[0054] Specifically, at least one lighting device may be arranged in the lighting fixture, and each lighting device may be distributed on the surface of the lighting fixture around the axis of the lighting fixture, and the direction of the irradiation light emitted by each lighting device may be perpendicular to the tangent line of the line of the illuminated space at the location of the lighting fixture. For example, Figure 2b As shown, lighting devices a, b and c can be arranged around the surface of lighting fixture A, and the irradiation direction E1-E1' of lighting device a and the irradiation direction D1-D1' of lighting device b can be perpendicular to the tangent c1-c1' respectively.

[0055] Step 102, obtaining boundary information of the space to be illuminated, and determining target lighting areas corresponding to the lighting equipment according to the boundary information.

[0056] The space to be illuminated may be a space that needs to be illuminated. Specifically, the space to be illuminated may be a space that needs to obtain uniform light intensity to improve the lighting effect, such as underground tunnels, underground caverns, etc. The space to be illuminated may include closed spaces, semi-closed spaces, and open spaces. The closed space may be a space that cannot obtain other light sources except for lighting equipment. The semi-closed space may be a space that has other auxiliary light sources except for lighting equipment, but has some dark areas, where the dark areas may be areas that cannot be illuminated by the auxiliary light sources. The open space may be a space that has other light sources except for lighting equipment and does not have any dark areas.

[0057] The above-mentioned boundary information may include information for describing the boundary of the space to be illuminated, such as one or more of information such as points, line segments, curves, etc. for describing the boundary of the space to be illuminated.

[0058] After determining the space to be illuminated that needs to be illuminated, the information such as points, line segments, curves, etc. used to describe the boundary of the space to be illuminated can be obtained through devices that collect environmental information such as optical sensors or acoustic wave sensors. Then, the boundary information of the space to be illuminated can be determined based on the information such as points, line segments, curves, etc. used to describe the boundary of the space to be illuminated.

[0059] Specifically, the optical sensor may include but is not limited to a laser radar sensor, a three-dimensional scanner, and other devices, and the acoustic sensor may include but is not limited to an ultrasonic sensor, a sonar sensor, and other devices. The optical sensor and / or the acoustic sensor may be installed on the lighting device, or may be provided separately.

[0060] In practical applications, at least one scanning point for the boundary of the space to be illuminated can be collected by an optical sensor or an acoustic wave sensor, and the line segment equation and / or curve equation used to describe the space to be illuminated can be determined based on the position information of the scanning point and the association relationship between each scanning point, and the line segment equation and / or curve equation used to describe the space to be illuminated can be determined as the boundary information of the space to be illuminated.

[0061] Specifically, the line segment equations and curve equations used to describe the space to be illuminated can be converted into a polar coordinate data set centered on the lighting device when executing the subsequent steps of determining the target lighting area corresponding to the lighting device, and the polar coordinate data set can then be used to execute the subsequent steps of determining the target lighting area corresponding to the lighting device.

[0062] In addition, in another example, when collecting at least one scanning point for the boundary of the space to be illuminated, a scanning point set can be generated, and the noise points in the scanning point set can be removed. For example, a multi-point continuous smoothing method can be used to remove the noise points. Based on the position information of the scanning points in the scanning point set after removing the noise points and the correlation relationship between each scanning point, the continuous line segments and / or continuous curves used to describe the space to be illuminated can be determined, and the continuous line segments or continuous curves used to describe the space to be illuminated can be determined as the boundary information of the space to be illuminated.

[0063] In one example of the present application, the space to be illuminated can be determined based on the user's lighting needs to determine the space to be illuminated that currently needs to be illuminated, or a timed lighting strategy can be set in advance, and the space to be illuminated that needs to be illuminated can be determined according to the timed lighting strategy. For example, if space A is to undergo a spatial structure quality inspection every three days, then it can be pre-set to be illuminated every three days. Similarly, space B can be illuminated every five days. Then, when detecting a space to be illuminated that meets the timed lighting strategy, it can also predict the space to be illuminated that will need to be illuminated in the future based on historical lighting information over a period of time.

[0064] After determining at least one lighting device for illuminating the space to be illuminated and acquiring boundary information of the space to be illuminated, target lighting areas corresponding to the lighting devices can be determined respectively according to the boundary information.

[0065] In practical applications, the area in the space to be illuminated that needs to be illuminated by the lighting equipment can be determined based on the boundary information. For example, three lighting equipment for illuminating the space to be illuminated can be determined, specifically lighting equipment A, lighting equipment B, and lighting equipment C. The space to be illuminated can then be divided into space a to be illuminated, space b to be illuminated, and space c to be illuminated. The space a to be illuminated can be determined as the target lighting area that needs to be illuminated by the lighting equipment A. By analogy, the target lighting areas corresponding to the lighting equipment B and the lighting equipment C can be determined respectively.

[0066] Step 103: determine a control coefficient of the lighting device according to the target lighting area, and control the lighting device to illuminate the space to be illuminated based on the control coefficient.

[0067] Among them, the control coefficient can be a coefficient used to control the lighting of the lighting device. The control coefficient may include an angle adjustment coefficient for the lighting device and / or a brightness adjustment coefficient for the lighting device. The angle adjustment coefficient can be used to adjust the angle of the lighting device. The brightness adjustment coefficient can be used to adjust the brightness of the lighting device. The brightness adjustment coefficient may include an overall adjustment coefficient for adjusting the overall brightness of the lighting device and an output control coefficient for adjusting the output power of the lighting device.

[0068] After determining the target lighting area corresponding to the lighting device, the control coefficient required when the lighting device illuminates the corresponding target lighting area can be determined according to the target lighting area.

[0069] As an example, when there are at least two lighting devices, the overall brightness of the lighting devices can be adjusted based on demand, and then the output power of each lighting device can be adjusted separately so that the illuminated space can obtain the required lighting effect. The brightness adjustment coefficient in the control coefficient of each lighting device can include an overall adjustment coefficient and an output control coefficient. When there is only one lighting device, it is only necessary to control the lighting device for lighting, and the brightness adjustment coefficient in the control coefficient of the lighting device can only include the output control coefficient.

[0070] After obtaining the control coefficient of the lighting device, the lighting device can be adjusted based on the control coefficient, and the adjusted lighting device can be used to illuminate the space to be illuminated.

[0071] In practical applications, the output power of the lighting device can be adjusted according to the control coefficient to obtain the brightness corresponding to the brightness adjustment coefficient. The lighting angle of the lighting device can also be adjusted, or the lighting angle of the light-emitting lamp beads in the lighting device can be adjusted to obtain the angle corresponding to the angle adjustment coefficient.

[0072] For example, the maximum luminous intensity of a lighting device can be expressed as q max , and the luminous intensity of the i-th lighting device to be controlled can be q i , which is the controlled luminous intensity of the i-th lighting device, the overall adjustment coefficient can be C, and the output control coefficient of the i-th lighting device can be k i , then the required luminous intensity of the i-th lighting device can be expressed by the following formula:

[0073] q i = C·k i q max

[0074] Based on this, the lighting equipment used to illuminate the space to be illuminated is controlled by adopting a control coefficient determined based on the boundary information of the space to be illuminated, so that the lighting equipment can perform numerical control lighting on the space to be illuminated in a zoned manner, and the space to be illuminated can obtain the required lighting effect, such as uniform lighting effect, thereby reducing the light and shadow caused by defects in the space to be illuminated, improving the lighting effect of the space to be illuminated, and improving the quality of image acquisition, thereby improving the reliability and accuracy of detection and evaluation of the structural quality of the construction space based on the acquired images.

[0075] In an embodiment of the present application, by acquiring boundary information of the space to be illuminated and determining at least one lighting device used to illuminate the space to be illuminated, the target lighting areas corresponding to the lighting devices can be determined respectively according to the boundary information, and the control coefficient of the lighting device can be determined according to the target lighting area, so that the lighting device can be controlled based on the control coefficient to illuminate the space to be illuminated, so that the space to be illuminated obtains uniform illumination, the lighting effect of the space to be illuminated is improved, the quality of image acquisition is improved, and thus the reliability and accuracy of detecting and evaluating the structural quality of the space to be illuminated based on the acquired images is improved, and the safety hazards caused by the inability to accurately detect and evaluate the structural quality of some spaces to be illuminated are reduced.

[0076] See also Figure 3 , Figure 3 A flowchart of a method for controlling a lighting device provided by another embodiment of the present application is shown, which may specifically include the following steps:

[0077] Step 301: determine at least one lighting device for illuminating a space to be illuminated.

[0078] Step 302: Obtain boundary information of the space to be illuminated.

[0079] For the related descriptions of step 301 to step 302, please refer to the descriptions of step 101 to step 102, which will not be repeated here.

[0080] Step 303: Determine at least one pending lighting area according to the boundary information and the precision parameter.

[0081] The precision parameter may be a control parameter related to the division of the pending lighting area, and the precision parameter may be pre-set, or generated in response to control information input by a user, or determined according to the number of lighting devices in the lighting fixture. The precision parameter may include an angle control parameter of the boundary of the space to be illuminated relative to the lighting device, an angle control parameter determined based on user needs, and the pending lighting area may include boundary information of the pending lighting area and spatial information of the pending lighting area, and the spatial information of the pending lighting area may include the volume of the pending lighting area.

[0082] After the boundary information of the space to be illuminated is acquired, the space to be illuminated may be divided into at least one to-be-determined illumination area according to the boundary information and the precision parameter.

[0083] In an embodiment of the present application, step 303 may include steps 3031 to 3033:

[0084] Step 3031: Determine at least one boundary line segment according to the boundary information and the precision parameter.

[0085] The boundary line segment may be used to describe the outline of the space to be illuminated, and the boundary line segment may include the length information of the boundary line segment and the association relationship between the boundary line segment and other boundary line segments.

[0086] After the boundary information of the space to be illuminated is obtained, the space to be illuminated may be divided into at least one subdivided area according to the accuracy parameter.

[0087] For example, assuming that the control information output by the user is to set the precision parameter to a 30-degree control angle, the generated precision parameter is to divide the space to be illuminated into 12 sub-areas every 30 degrees, and then the space to be illuminated can be divided into 12 sub-areas every 30 degrees; and when the precision parameter is determined based on the number of lighting devices, the generated precision parameter can be set as a multiple of the number of lighting devices. Assuming that the number of lighting devices used to illuminate the space to be illuminated is m, the generated precision parameter can be N times of m, where N is a positive integer. After the generated precision parameter is N times, the space to be illuminated can be divided into S sub-areas, where S=360 / (m*N).

[0088] After obtaining at least one subdivision area, the intersection points of each subdivision area associated with the boundary information can be determined. For example, the intersection points of each subdivision area with the line segment equation or the curve equation can be determined based on the line segment equation or the curve equation in the polar coordinate data set in the boundary information, or the intersection points of each subdivision area with the continuous line segments or continuous curves in the scanning point set can be determined, thereby obtaining the intersection points of each subdivision area associated with the boundary information.

[0089] After obtaining the intersection points associated with each region and the boundary information, the intersection points associated with each region and the boundary information and the points, line segments, and curves in the boundary information may be connected to obtain at least one boundary line segment.

[0090] Step 3032: Determine the distance information between the lighting device and the boundary line segment, and determine the angle information of the boundary line segment relative to the lighting device.

[0091] The distance information may be obtained by using a laser radar to measure the distance. Generally, the distance information may be the distance between the boundary line segment and the lighting device. Similarly, the angle information may be the angle of the boundary line segment relative to the lighting device.

[0092] After the boundary line segment is determined, the distance information between the lighting device and the boundary line segment can be obtained by using methods such as laser ranging, and then the angle information of the boundary line segment relative to the lighting device can be calculated based on the length information and distance information of the lighting device.

[0093] In particular, when obtaining distance information, for each boundary line segment, the lighting device that can illuminate the boundary line segment can be determined in advance from all lighting devices, and then only the distance between the lighting device that illuminates the boundary line segment and the boundary line segment needs to be obtained. Similarly, the angle information of the boundary line segment relative to the lighting device that illuminates the boundary line segment can be obtained.

[0094] It should be understood that since the light source of the lighting device is diffusely illuminated, in addition to the area directly facing the lighting device, the area on the side of the lighting device will also be illuminated by the diffuse illumination of the lighting device, that is, the angle of the diffuse illumination of the lighting device can be the angle of the boundary segment relative to the lighting device.

[0095] like Figure 2a As shown, angle α and angle β can be the angle information of the boundary line segment relative to the lighting device illuminating the boundary line segment, and R can be expressed as the distance information between the lighting device and the boundary line segment, L o Can be expressed as the length of the lighting fixture.

[0096] Sub-step 3033, generating a pending lighting area corresponding to the boundary line segment according to the distance information and the angle information.

[0097] After the distance information and the angle information are obtained, the determined distance information and the angle information may be used to describe the boundary line segment relative to the to-be-determined lighting area of ​​the lighting device.

[0098] Specifically, the undetermined lighting area corresponding to the boundary segment can be described by the following formula:

[0099] V i =2 / 3(S i R i )·[tan(α)+tan(β)]+L o S i

[0100] Among them, V i It can be expressed as the undetermined lighting area corresponding to the boundary segment i, S i It can be expressed as the cross-sectional area corresponding to the undetermined illumination area, R i It can be expressed as the distance between the boundary line segment i and the lighting device, and the angle α and the angle β can be the angle information of the boundary line segment i relative to the lighting device.

[0101] In practical applications, since the precision parameter can be adjusted, the pending illumination area generated by the boundary line segment will also change with the adjustment of the precision parameter, that is, the higher the precision of the precision parameter adjustment, the closer the generated pending illumination area will be to the actual outline of the space to be illuminated.

[0102] Step 304 , respectively determining the illumination ranges of the illumination devices, and determining the target illumination area corresponding to the illumination devices from all the illumination areas to be determined according to the illumination ranges.

[0103] Among them, the illumination range can be the maximum range that the lighting equipment can illuminate, or the optimal range that the lighting equipment can achieve the best lighting effect, or it can be the lighting range adjusted in response to user needs. The target lighting area can be the area in the space to be illuminated that needs to be illuminated by the lighting equipment.

[0104] After obtaining the pending lighting area, the illumination range of each lighting device may be determined respectively, and then the pending lighting area in the illumination range may be determined as the target lighting area among all the pending lighting areas.

[0105] In a specific implementation, since the pending lighting area will change with the adjustment of the precision parameters, the higher the accuracy of the precision parameters, the obtained pending lighting area will be closer to the contour of the actual space to be illuminated, thereby making the error between the target lighting area determined based on the pending lighting area and the contour of the actual space to be illuminated smaller.

[0106] In one embodiment, when there are multiple lighting devices, the target lighting area of ​​each lighting device may be determined in turn, or at least one target lighting device may be selected from all lighting devices, and then the target lighting area corresponding to each target lighting device may be determined respectively.

[0107] In practical applications, the lighting demand for the space to be illuminated may be for a specific area, and the specific area is only illuminated by lighting equipment at a specific angle and position. In this case, a target lighting equipment for illuminating the specific area can be selected from all lighting equipment. In addition, the lighting equipment required to meet the minimum lighting requirement of the space to be illuminated can be determined as the target lighting equipment, without the need to use all lighting equipment to illuminate the space to be illuminated, thereby reducing energy waste.

[0108] In an embodiment of the present application, determining the target lighting area corresponding to the lighting device from all the lighting areas to be determined according to the illumination range in step 304 may include the following steps:

[0109] Step 3041: Determine at least one middle lighting area within the lighting range from all the lighting areas to be determined according to the lighting range.

[0110] The to-be-determined lighting area may include volume information of the first area, and the middle lighting area may be the to-be-determined lighting area within the illumination range.

[0111] After the illumination range of the lighting device is obtained, the to-be-determined illumination area in the illumination range may be determined as at least one middle illumination area among all the to-be-determined illumination areas.

[0112] In a specific implementation, when determining that the accuracy parameter is generated based on the lighting device, the number N of the lighting devices can be determined. Since the lighting devices are arranged in the above-mentioned cylindrical or prismatic lighting fixtures, that is, the range that the lighting devices can illuminate can be the space centered on the lighting device and perpendicular to the axis of the lighting device, it can be determined that the illumination range that each lighting device can cover is 360 / N, that is, the illumination range of the i-th lighting device can be [(i-1)φ, iφ], φ=360 / N, and the angle θ corresponding to the center of the i-th lighting device can be expressed as θ=(i-0.5)φ, and then, with the lighting device as the center, at least one intermediate lighting area located in [(i-1)φ, iφ] can be determined in all pending lighting areas.

[0113] It should be understood that the above-mentioned illumination range [(i-1)φ, iφ] is obtained based on the situation where the lighting equipment needs to achieve 360-degree uniform illumination. In actual applications, when only a specific area in the illumination space needs to be uniformly illuminated, or when the intensity of diffuse illumination between each lighting equipment needs to be combined to achieve uniform illumination, the illumination range will also be changed by adjusting the illumination angle of the lighting equipment.

[0114] Step 3042: determine the target lighting area corresponding to the lighting device according to all the intermediate lighting areas, and perform cumulative calculation on the first area volume information in all the intermediate lighting areas to generate second area volume information for the target lighting area.

[0115] After all the intermediate lighting areas are obtained, all the intermediate lighting areas can be merged according to the association relationship of the boundary information to generate the target lighting area. At the same time, the first area volume information in all the intermediate lighting areas can be accumulated and calculated, and then the second area volume information for the target lighting area can be generated to obtain the target lighting area including the second area volume information.

[0116] For example, according to the illumination range, the to-be-determined illumination area 1, the to-be-determined illumination area 2, and the to-be-determined illumination area 3 in the illumination range are determined from all the to-be-determined illumination areas, that is, the middle illumination area 1, the middle illumination area 2, and the middle illumination area 3. The middle illumination area 1, the middle illumination area 2, and the middle illumination area 3 can be merged to obtain the target illumination area i. The regional volume information V1 of the to-be-determined illumination area 1, the regional volume information V2 of the to-be-determined illumination area 2, and the regional volume information V3 of the to-be-determined illumination area 3 can be accumulated and calculated to obtain the regional volume information V1 of the target illumination area i. i .

[0117] like Figure 4 As shown, Figure 4 It describes that lighting fixture A is in the space to be illuminated, lighting equipment a, lighting equipment b, and lighting equipment c can be evenly arranged in the prismatic lighting fixture, θ can be expressed as the illumination range of lighting equipment a, v1, v2, v3, v4, and v5 can be respectively expressed as pending lighting area 1, pending lighting area 2, pending lighting area 3, pending lighting area 4, and pending lighting area 5 determined based on accuracy parameters and boundary information, among which pending lighting area 2, pending lighting area 3, and pending lighting area 4 are in the illumination range of lighting fixture a, namely middle lighting area 2, middle lighting area 3, and middle lighting area 4, and the middle lighting area 2, middle lighting area 3, and middle lighting area 4 are merged to obtain the target lighting area corresponding to lighting fixture a.

[0118] Step 305: determine a control coefficient of the lighting device according to the target lighting area, and control the lighting device to illuminate the space to be illuminated based on the control coefficient.

[0119] In practical applications, as the accuracy of the precision parameter increases, the error between the target lighting area and the actual contour of the space to be illuminated will be smaller, which will make the control coefficient of the lighting equipment determined based on the target lighting area more accurate, and the effect of controlling the lighting equipment based on the control coefficient to illuminate the space to be illuminated will be better.

[0120] In an embodiment of the present application, by acquiring boundary information of the space to be illuminated, at least one lighting device for illuminating the space to be illuminated is determined, at least one to-be-determined lighting area is determined based on the boundary information and the precision parameter, the illumination range of the lighting device is determined respectively, and based on the illumination range, the target lighting area corresponding to the lighting device is determined from all the to-be-determined lighting areas, the control coefficient of the lighting device is determined based on the target lighting area, and the lighting device is controlled to illuminate the space to be illuminated based on the control coefficient, so that the target lighting area corresponding to the lighting device can be determined based on the boundary information and the precision parameter, and then the lighting device can be controlled to illuminate the target lighting area by the control coefficient determined by the target lighting area, so that the lighting device can illuminate the target lighting area accordingly and achieve the corresponding lighting effect, thereby improving the lighting effect of the lighting device on the space to be illuminated, thereby improving the quality of the image collected based on the lighting effect, and further improving the reliability and accuracy of the detection and evaluation of the structural quality of the construction space based on the collected image, thereby reducing the safety hazards caused by the inability to accurately detect and evaluate the structural quality of some construction spaces.

[0121] See also Figure 5 , Figure 5 A flowchart of a method for controlling a lighting device provided by another embodiment of the present application is shown, which may specifically include the following steps:

[0122] Step 501: determine at least one lighting device for illuminating a space to be illuminated.

[0123] Step 502: Acquire boundary information of the space to be illuminated, and determine target illumination areas corresponding to the illumination devices according to the boundary information.

[0124] For the related descriptions of step 501 to step 502, please refer to the descriptions of step 101 to step 102, which will not be repeated here.

[0125] Step 503: Determine area ratio information of the lighting equipment according to the target lighting area.

[0126] Among them, the area ratio information can be the ratio information between the target lighting areas corresponding to each lighting device, and the area ratio information may include area ratio information for the target lighting area, volume ratio information for the target lighting area, light intensity ratio information for the target lighting area, and other ratio information of parameters used to improve the lighting effect of the target lighting area.

[0127] After the target lighting area corresponding to the lighting device is determined, each target lighting area may be compared respectively to obtain ratio information of each target lighting area relative to other target lighting areas.

[0128] In one embodiment of the present application, the area ratio information can also be the ratio information between the target lighting area and the parameters set based on experience or user needs, and then the corresponding parameters in each target lighting area can be compared with the parameters set based on experience or user needs to obtain the ratio information of each target lighting area relative to the parameters set based on experience or user needs.

[0129] In an embodiment of the present application, step 503 may include the following steps:

[0130] Step 5031: determine a reference lighting area from the target lighting areas corresponding to all lighting devices.

[0131] Among them, the reference lighting area can be an area among all target lighting areas used for reference comparison with other target lighting areas, the reference lighting area can be an area where the value of a specific parameter in all target lighting areas is an extreme value, the specific parameter can be a parameter related to the lighting effect, such as a volume parameter, an area parameter, a light intensity parameter, etc., then the reference lighting area can be the area with the smallest area among all target lighting areas, or the area with the largest volume among all target lighting areas.

[0132] After determining the target lighting area corresponding to the lighting equipment, the values ​​of each parameter in all the target lighting areas can be compared, and then the target lighting area in which the value of a certain parameter in all the target lighting areas is an extreme value can be determined as the reference lighting area. Alternatively, the values ​​of each parameter in all the target lighting areas can be compared with the set values ​​respectively, and then the target lighting area in which the value of a certain parameter in all the target lighting areas has the smallest difference with the set value can be determined as the reference lighting area.

[0133] In practical applications, since the lighting effect of the lighting equipment will be affected by various factors in the space to be illuminated, such as the influence of aerosols such as air and particulate matter in the space to be illuminated on the light, and the influence of various reflections, scatterings and other situations of the light in the space to be illuminated, it can be set that the influence of aerosols in the space to be illuminated on the light and the influence of various reflections, scatterings and other situations of the light in the space to be illuminated are negligible, and then it can be proposed that the light output by the lighting equipment can all act on the target lighting area that should be illuminated, and the lighting effect is positively correlated with the luminous intensity output by the lighting equipment, and when the luminous intensity of the lighting equipment is determined, the lighting effect of the space to be illuminated is negatively correlated with the volume of the illumination range of the lighting equipment. Similarly, when the luminous intensity of the lighting equipment is determined, it can be proposed that the lighting effect of the space to be illuminated is negatively correlated with the area of ​​the illumination range of the lighting equipment.

[0134] Based on the above assumptions, the relationship between the lighting effect of the space to be illuminated and the illumination range of the lighting equipment can be determined. For example, when the light emission of the lighting equipment is constant, the larger the illumination range of the lighting equipment, the worse the lighting effect of the space to be illuminated.

[0135] In a specific implementation, the lighting effect test can be carried out in advance for spaces in different environments based on different assumptions, and then the parameters most relevant to the lighting effect in spaces in different environments can be determined. In actual application, based on the spaces to be illuminated in different environments, the parameters that have the greatest impact on the lighting effect of the spaces to be illuminated can be determined, and then the reference lighting area can be determined based on the parameters. For example, when it is determined that the space to be illuminated is an underground space, it can be determined that the parameter that has the greatest impact on the lighting effect of the underground space is the volume, and then the target lighting area with the largest volume among all target lighting areas can be determined as the reference lighting area.

[0136] Specifically, the reference lighting area may be determined using the following formula.

[0137] V max =max(V1, V2, V3...V N )

[0138] Among them, V maxIt can be expressed as the target lighting area with the largest volume among all target lighting areas, V1 can be expressed as the volume of target lighting area 1, V2 can be expressed as the volume of target lighting area 2, and so on.

[0139] Similarly, the reference lighting area can be determined based on formulas of other parameters.

[0140] Step 5032: Determine area ratio information of the target lighting area corresponding to the lighting device relative to the reference lighting area according to the target lighting area and the reference lighting area.

[0141] After determining the reference lighting area, the parameters in the reference lighting area can be determined, and then the values ​​of the parameters in the target lighting area can be compared with the values ​​of the parameters in the reference lighting area to obtain the area ratio information of the target lighting area relative to the reference lighting area.

[0142] For example, when it is determined that the parameter that has the greatest impact on the lighting effect of the lighting space is volume, the ratio of the volume of the target lighting area to the volume of the reference lighting area may be determined, that is, the area ratio information of the target lighting area relative to the reference lighting area.

[0143] Step 504: Calculate the control coefficient of the lighting equipment according to the area ratio information.

[0144] After the area ratio information is obtained, the control coefficient of the lighting equipment can be calculated according to the area ratio information.

[0145] As an example, the weight corresponding to the lighting device may also be determined, and the control coefficient of the lighting device may be calculated based on the weights corresponding to different lighting devices and the area ratio information corresponding to the lighting device.

[0146] In actual applications, different lighting devices will have different maximum luminous amounts, and the weight corresponding to the lighting device can be set based on the maximum luminous amount of each lighting device, so that the lighting device can be controlled based on the control coefficient calculated based on the weight corresponding to the lighting device and the area ratio information corresponding to the lighting device, and all lighting devices can also be controlled to obtain a lighting effect with luminous amount and luminous intensity that meets the requirements.

[0147] For example, assuming that all current lighting devices have the same luminous intensity, that is, the weight of each lighting device is the same, the control coefficient of the lighting device can be determined using the following formula:

[0148] K i =V i / V max

[0149] Among them, V i / Vmax It can be expressed as the area ratio information of the lighting equipment, K i It can represent the control coefficient of lighting equipment. When the control coefficient only includes the output control coefficient, K i It can also be expressed as the output control coefficient of the lighting device.

[0150] In one embodiment of the present application, the weight corresponding to the lighting device may also be related to the position of the lighting device. For example, the smaller the distance between the lighting device and the boundary of the target lighting area, the greater the weight.

[0151] Step 505: Control the lighting device to illuminate the space to be illuminated based on the control coefficient.

[0152] For the related description of step 505, please refer to the description of step 103, which will not be repeated here.

[0153] In an embodiment of the present application, by acquiring boundary information of the space to be illuminated, at least one lighting device for illuminating the space to be illuminated is determined, and according to the boundary information, the target lighting areas corresponding to the lighting devices are respectively determined, and then according to the target lighting areas, the area proportion information of the lighting devices is determined, and according to the area proportion information, the control coefficient of the lighting devices is calculated, and the lighting devices are controlled to illuminate the space to be illuminated based on the control coefficient, so that the lighting devices can be controlled to illuminate the target lighting area accordingly based on the control coefficient of the lighting devices generated by the area proportion information, so that the lighting devices can illuminate the target lighting area accordingly in proportion, and the required lighting effect can be met, thereby improving the lighting effect of the lighting devices on the space to be illuminated, thereby improving the quality of images collected based on the lighting effect, and further improving the reliability and accuracy of detecting and evaluating the structural quality of the construction space based on the collected images, thereby reducing the safety hazards caused by the inability to accurately detect and evaluate the structural quality of some construction spaces.
