[0051] The present application will be further described in the following by way of examples, but the present application is not limited in the scope of the described examples.

[0052] Embodiment 1

[0053] The control method of indoor light of the present embodiment, as shown in the figure, comprises: Figure 1

[0054] ​S110, determine the target lesion area of the patient.

[0055] S120, calculate the lighting weight information corresponding to the lighting device according to the distance information and / or angle information between the target lesion area and the lighting device.

[0056] S130, control the lighting device to emit light rays conforming to the corresponding lighting weight information to the target lesion area.

[0057] The composite operating room has many functions, and the requirements for light intensity are different in different working modes. For example, in the preoperative examination stage, there is no need for particularly bright light, and in the intraoperative performance stage, shadowless light is needed. Therefore, in order to meet the flexible operation needs, the composite operating room usually includes various instruments, such as DSA imaging machines, various auxiliary equipment and flexible rotating patient beds and other equipment.

[0058] For the above step S110, the composite operating room is composed of a plurality of lighting devices (L1, L2, L3…, L i ), a visual detection camera, a patient bed and a software / hardware device matched with the operating room. In order to obtain a wide field of view, a visual detection camera is installed at the upper corner position of the composite operating room. When there are multiple visual detection cameras, the application form of the visual detection camera can be appropriately adjusted. The image in the composite operating room is captured by the visual detection camera installed in the composite operating room, so as to detect the position information of the patient bed, the position information of the patient on the patient bed and the body shape information of the patient on the patient bed in real time, and then automatically identify the target lesion area of the patient according to the detected results and the current operation type.

[0059] For example, if the current operation type is heart surgery, the heart region of the patient is automatically identified according to the detected position information of the patient bed, the position information of the patient, the body shape information of the patient and the heart surgery type. By automatically detecting the position information of the patient bed, the position information of the patient on the patient bed and the body shape information of the patient on the patient bed in real time through the visual detection camera, the accuracy of identifying the target lesion area of the patient can be effectively improved, and the intelligent degree of indoor light control can be enhanced.

[0060] For the above step S120, each lighting device of the lighting device group of the composite operating room has different lighting weight information, which is used to distribute the output power corresponding to each lighting device. When the patient is operated, shadowless light is expected to be formed in the composite operating room. The closer the angle of vertical illumination of the target lesion area, the better the effect of the light. In other words, the closer the angle of light incidence to the target lesion area to 0°, the better the light effect, and the closer the lighting weight information corresponding to the lighting device to 0°.

[0061] According to the distance information between the visual detection camera and each lighting device and the distance information between the target lesion area and the target lesion area, the distance information between the target lesion area and each lighting device is calculated, and the angle information between the target lesion area and each lighting device is obtained according to the distance information. The angle information represents the included angle between the line connecting the target lesion area and each lighting device and the vertical direction.

[0062] In actual applications, other calculation methods can also be used, and the calculation method of the angle information to obtain the corresponding lighting weight information of the lighting device is not limited.

[0063] For the above step S130, the lighting device includes a first lighting device, a second lighting device and a third lighting device. The first lighting device is controlled to emit light to the target lesion area according to the corresponding first lighting weight information, the second lighting device is controlled to emit light to the target lesion area according to the corresponding second lighting weight information, and the third lighting device is controlled to emit light to the target lesion area according to the corresponding third lighting weight information. It should be noted that the first lighting weight information, the second lighting weight information and the third lighting weight information can be the same or different.

[0064] When the target lesion area is determined, the lighting device is controlled to automatically emit light to the target lesion area according to the calculated lighting weight information at a preset time period in the use of the indoor light control method provided by the embodiment of the present application, without the need for manual operation in the operating room or setting in advance according to the start time of the operation, thereby improving the user experience.

[0065] In an optional embodiment, as shown in Figure 2 S120 specifically includes:

[0066] S121, detecting first distance information between the target lesion area and the camera.

[0067] S122, obtaining second distance information between the lighting device and the camera; the lighting device and the camera are respectively located at different positions in the operating room.

[0068] S123, calculating the corresponding lighting weight information of the lighting device according to the first distance information and the second distance information.

[0069] The visual detection camera can be a common visual detection camera including a camera. The common visual detection camera is low in price and does not need special equipment such as a sensor, thereby greatly reducing the cost of determining the target lesion area of the patient. For the steps S121-S123, when the visual detection camera is installed and calibrated, the spatial distance information between each lighting device and the visual detection camera needs to be measured. As shown in Figure 3 FIG. 1, a camera, a patient bed, and i lighting devices are arranged in a composite operating room, and each lighting device and the camera are respectively located at different positions above the composite operating room. The number of lighting devices needs to meet the power requirement under different surgical models, and the lighting devices are preferably distributed at equal intervals on the ceiling of the composite operating room and arranged around the patient bed in the vertical direction.

[0070] L i represents the i-th lighting device, M represents the camera, and the target lesion area (star mark shown in the figure). i , h i , w i represents the first distance information between the i-th lighting device and the camera, l i represents the length value of the i-th lighting device and the camera in the three-dimensional space coordinate system, h i represents the height value of the i-th lighting device and the camera in the three-dimensional space coordinate system, w i represents the width value of the i-th lighting device and the camera in the three-dimensional space coordinate system. l , M h , M w represents the second distance information between the target lesion area and the camera, M l represents the length value of the target lesion area and the camera in the three-dimensional space coordinate system, M h represents the height value of the target lesion area and the camera in the three-dimensional space coordinate system, M w represents the width value of the target lesion area and the camera in the three-dimensional space coordinate system.

[0071] In an optional embodiment, as shown in Figure 4 , the step S123 specifically includes:

[0072] S1231, calculating third distance information between the lighting device and the target lesion area according to the first distance information and the second distance information.

[0073] S1232, calculating angle information between the lighting device and the target lesion area based on the third distance information, the first distance information, and the second distance information.

[0074] S1233, calculating lighting weight information according to the angle information.

[0075] For steps S1231-S1233 above, the third distance information P between the i-th lighting device and the target lesion area is calculated from the first distance information and the second distance information according to the following first calculation formula. i .like Figure 4 As shown, based on P in the third distance information i h in the first distance information i M in the second distance information h Calculate the angle information θ between the i-th lighting device and the target lesion area using the second calculation formula below. i It can be based on the angle information θ i The lighting weight information W corresponding to the i-th lighting device is calculated according to the third calculation formula below. i Alternatively, the length value l between the i-th lighting device and the camera in the three-dimensional coordinate system can be expressed as... i The height value M of the i-th lighting device and camera in the three-dimensional coordinate system h The sum of the distances P between the i-th lighting device and the target lesion area. i The proportion of W is used as lighting weight information. i .

[0080] <Formula 3>

[0081]

[0082] In one alternative implementation, such as Figure 6 As shown, the lighting equipment includes multiple components. Before step S130, the control method further includes:

[0083] S1301, detect whether there is any obstruction between the target lesion area and each lighting device; if so, proceed to step S1302.

[0084] S1302, The lighting weight information corresponding to the lighting equipment with obstruction is corrected to obtain the actual lighting weight information.

[0085] Because a hybrid operating room contains not only various instruments but also multiple doctors and nursing staff, the demand for shadowless lighting is high. It is necessary to adjust the lighting weight information of any obstructed lighting equipment to a smaller value to avoid creating shadows.

[0086] likeFigure 7 As shown, the presence of obstructing objects along the irradiation path between each lighting device and the same target lesion area is sequentially detected. Figure 7 The diagram shows a cube. When obstructing objects are present, the lighting weight information corresponding to the lighting equipment with obstructing objects needs to be corrected. It should be noted that when all lighting equipment in the hybrid operating room has obstructing objects on its irradiation path to the same target lesion area, it is not necessary to correct the lighting weight information of each obstructing lighting equipment; instead, it is treated as a special case. That is, it is automatically assumed that there are no obstructions between the target lesion area and all lighting equipment, and each lighting equipment is directly controlled to emit light conforming to its corresponding lighting weight information towards the target lesion area.

[0087] Secondly, light obstruction detection can be performed during the surgical imaging examination, the surgical procedure itself, or the postoperative treatment phase. However, light obstruction detection is unnecessary during the surgical downtime, the startup preparation phase, and the operating room cleaning phase. The need for obstruction detection between the target lesion area and each lighting device can be determined based on the surgical operating mode. Those skilled in the art can set the preconditions for obstruction detection according to the actual situation; this embodiment does not impose specific limitations.

[0088] Step S130 specifically includes:

[0089] S131, control the lighting equipment to emit light that conforms to the corresponding actual lighting weight information to the target lesion area.

[0090] For example, the lighting equipment includes a first lighting device, a second lighting device, and a third lighting device. When there is an obstruction between the first lighting device and the target lesion area, an obstruction between the second lighting device and the target lesion area, and no obstruction between the third lighting device and the target lesion area, the first lighting device is controlled to emit light with corresponding actual lighting weight information to the target lesion area, the second lighting device is controlled to emit light with corresponding actual lighting weight information to the target lesion area, and the third lighting device is controlled to emit light with corresponding lighting weight information to the target lesion area.

[0091] In one alternative implementation, such as Figure 8 As shown, step S110 specifically includes:

[0092] S111: Collect the human model information and surgical information for the current surgery.

[0093] S112, determine the target lesion area based on human model information and surgical information.

[0094] The operation information includes an operation type and a work mode, and the work mode includes at least one of an idle mode, a start-up preparation mode, an image examination mode, a surgery stage mode, a post-surgery treatment mode, and a post-surgery cleaning mode.

[0095] According to the work mode in the operation information, it is determined whether the target lesion area needs to be determined. When the work mode is the idle mode, the start-up preparation mode, the post-surgery cleaning mode, or the shut-down mode, the target lesion area does not need to be determined. When the work mode is the image examination mode, the post-surgery stage mode, or the post-surgery treatment mode, the target lesion area needs to be determined.

[0096] When the target lesion area needs to be determined, the position of the target lesion area of the patient in the current operation is determined according to the operation type in the operation information. For example, when the operation type in the operation information is a heart surgery, the target lesion area is located at the heart position of the patient; when the operation type in the operation information is a liver surgery, the target lesion area is located at the liver position of the patient; and when the operation type in the operation information is an abdominal surgery, the target lesion area is located at the abdominal position of the patient.

[0097] In this embodiment, the control method further includes:

[0098] S1303, determining light intensity information according to the operation information.

[0099] The composite operating room has different requirements for light intensity in different work modes. For example, there is no requirement for light intensity in the idle mode, a weak light intensity is required in the start-up preparation mode, a weak light intensity is required in the image examination mode, a strong light intensity is required in the surgery stage mode, a strong light intensity is required in the post-surgery treatment mode, a medium light intensity is required in the post-surgery cleaning mode, and a weak light intensity is required in the shut-down mode.

[0100] It should be noted that the target lesion area of different operation types has different positions, and the requirements for light intensity are also slightly different. For example, the target lesion area located at the heart position of the patient requires a strong light intensity, the target lesion area located at the liver position of the patient requires a medium light intensity, and the target lesion area located at the abdominal position of the patient requires a medium light intensity. A person skilled in the art can also set the specific values of the light intensity corresponding to each work mode under different operation types according to the actual situation, and the range of the light intensity is not limited in this embodiment.

[0101] The light intensity information in the chart can be adaptively adjusted according to the actual use requirements and behavior preferences of each composite operating room. In this way, the personalized requirements of each composite operating room for the light intensity of multiple different lighting devices are met, and the power or brightness of each lighting device can be automatically adjusted, thereby improving the user experience. After the surgical information is determined, the light intensity information corresponding to the working mode and the target lesion area is selected from the chart.

[0102] Step S130 specifically includes:

[0103] S132, calculating the power information of the lighting device according to the light intensity information and the lighting weight information.

[0104] S133, based on the power information, controlling the lighting device to emit light to the target lesion area.

[0105] For steps S132-S133, when the light intensity information is determined, the light intensity information S and the lighting weight information W corresponding to the i th lighting device are determined. i The power information S corresponding to the i th lighting device is calculated according to the fourth calculation formula. i The i th lighting device is controlled to emit light to the target lesion area according to the power information S. i The calculated power information corresponding to different lighting devices can be different or the same.

[0106] <Formula 4>

[0107]

[0108] In an optional embodiment, as shown in Figure 9 , the light adjustment system in the composite operating room includes an indoor software control system, a visual detection camera, a light controller, and a lighting lamp group including multiple lighting devices. The indoor software control system extracts the working mode from the surgical information generated by the user input external instruction, and sends the working mode to the light controller. The visual detection camera detects the patient on the patient bed in real time, and automatically identifies the target lesion area according to the detected result and the current surgical mode, and sends the position information of the target lesion area to the light controller.

[0109] The light controller calculates different lighting weight information of different lighting devices according to first distance information between the target lesion area and the visual detection camera, and second distance information between each lighting device and the visual detector. Light intensity information of each lesion area in each working mode is stored in advance in a storage module of the light controller, and the target light intensity information is obtained by looking up the table in the storage module based on the target lesion area and the working mode. The power information of each lighting device is calculated according to the target light intensity information and the lighting weight information. Finally, each lighting lamp group is controlled to emit light corresponding to the aforementioned power information, realizing the intelligent adjustable shadowless light effect.

[0110] It should be noted that the storage module of the light controller supports user configuration of light intensity information in each working mode. The user can pre-configure the light intensity information according to the actual use requirements and behavior preferences of each composite operating room, save it to the storage module, and subsequently configure the light intensity information in each working mode according to the user's pre-configuration, and the user can arbitrarily adjust the light intensity information in each working mode. This way meets the individual needs of each composite operating room for the light intensity of multiple different lighting devices, and can automatically adjust the power or brightness of each lighting device, improving the user experience.

[0111] The embodiment provides a control method for indoor light. By controlling the lighting device to emit light calculated according to the distance information and / or angle information between the target lesion area and the lighting device, the power or brightness of each lighting device can be automatically adjusted, avoiding manual adjustment of the lighting parameters of each lighting device in the operating room, solving the problem of manually adjusting the shadowless light in the composite operating room, improving the intelligent degree of the shadowless light in the operating room, meeting the individual needs of each composite operating room for the light intensity of multiple different lighting devices, and enhancing the user experience.

[0112] Embodiment 2

[0113] The indoor light control system of the embodiment, as shown in Figure 10 The control system includes a determination module 310, a calculation module 320, and a control module 330.

[0114] The determination module 310 is configured to determine a target lesion area of a patient.

[0115] The calculation module 320 is configured to calculate lighting weight information corresponding to the lighting device according to distance information and / or angle information between the target lesion area and the lighting device.

[0116] The control module 330 is configured to control the lighting device to emit light conforming to the corresponding lighting weight information to the target lesion area.

[0117] The function of the complex operating room is more, the light intensity requirement is different under different working mode. For example, the preoperative examination stage does not need special bright light, the operation stage needs to provide shadowless light. Therefore, in order to meet the flexible operation needs, the complex operating room usually includes various instruments, such as DSA imaging machine, various auxiliary equipment and flexible rotating sickbed and other equipment.

[0118] The complex operating room is composed of a plurality of lighting devices (L1, L2, L3…, L i In order to obtain a wide field of view, a visual detection camera is installed at the upper corner position of the complex operating room. When there are multiple visual detection cameras, the application form of the visual detection camera can be adjusted appropriately. The image in the complex operating room is captured by the visual detection camera installed in the complex operating room, so as to detect the position information of the sickbed, the position information of the patient on the sickbed and the body shape information of the patient on the sickbed in real time, and the determination module 310 automatically identifies the target lesion area of the patient according to the detected results and the current operation type.

[0119] For example, if the current operation type is heart surgery, the heart region of the patient is automatically identified according to the detected position information of the sickbed, the position information of the patient, the body shape information of the patient and the heart surgery type. By automatically detecting the position information of the sickbed, the position information of the patient on the sickbed and the body shape information of the patient on the sickbed in real time through the visual detection camera, the accuracy of identifying the target lesion area of the patient can be effectively improved, and the intelligent degree of indoor light control can be enhanced.

[0120] Each lighting device of the lighting device group of the complex operating room has different lighting weight information, which is used to distribute the output power corresponding to each lighting device. When the patient is operated, shadowless light is expected to be formed in the complex operating room. The closer the angle of vertical illumination of the target lesion area, the better the effect of the light. In other words, the closer the angle of light incidence to the target lesion area is to 0°, the better the light effect, and the closer the lighting weight information corresponding to the lighting device is to 0°.

[0121] According to the distance information between the visual detection camera and each lighting device and the distance information between the target lesion area, the distance information between the target lesion area and each lighting device is calculated, and the angle information between the target lesion area and each lighting device is obtained according to the distance information. The angle information is solved by the calculation module 320 to obtain the lighting weight information corresponding to each lighting device. It should be emphasized that the angle information represents the included angle between the line connecting the target lesion area and each lighting device and the vertical direction.

[0122] In practical applications, other calculation methods can also be used, and the calculation method of the angle information calculating the lighting weight information of the lighting device is not limited to the above-mentioned trigonometric function solving calculation method.

[0123] For example, the lighting devices include a first lighting device, a second lighting device, and a third lighting device. The control module 330 controls the first lighting device to emit light rays conforming to the corresponding first lighting weight information to the target lesion area, controls the second lighting device to emit light rays conforming to the corresponding second lighting weight information to the target lesion area, and controls the third lighting device to emit light rays conforming to the corresponding third lighting weight information to the target lesion area. It should be noted that the first lighting weight information, the second lighting weight information, and the third lighting weight information can be the same or different.

[0124] When the indoor light control system provided by the embodiment of the present application is used, after the determination module determines the target lesion area, the control module immediately controls each lighting device to automatically emit light rays conforming to the calculated lighting weight information to the target lesion area at the same time within a preset time period, without the need for manual operation in the operating room or setting in advance according to the start time of the operation, thereby improving the user experience.

[0125] In an optional embodiment, as shown in Figure 11 The calculation module 320 specifically includes:

[0126] The detection unit 321 is configured to detect first distance information between the target lesion area and the camera.

[0127] The acquisition unit 322 is configured to acquire second distance information between the lighting device and the camera; the lighting device and the camera are located at different positions in the operating room.

[0128] The calculation unit 323 is configured to calculate lighting weight information corresponding to the lighting device according to the first distance information and the second distance information.

[0129] The visual detection camera can be a common visual detection camera including a camera. The common visual detection camera has a low price and does not need special equipment such as a sensor, thereby greatly reducing the cost of determining the target lesion area of the patient. When the visual detection camera is installed and calibrated, the spatial distance information between each lighting device and the visual detection camera needs to be measured. The operating room is provided with one camera, one patient bed, and i lighting devices. Each lighting device and the camera are located at different positions above the operating room, respectively. The number of lighting devices needs to meet the power requirement under different operation models, and the lighting devices are preferably distributed at equal intervals on the ceiling of the operating room and arranged around the patient bed in the vertical direction.

[0141]

[0142] In an optional embodiment, as shown in Figure 11 the lighting devices include a plurality of, and the control system further includes:

[0143] a detection module 3301 for detecting whether there is an obstruction between the target lesion area and each lighting device; if so, a correction module 3302 is invoked.

[0144] the correction module 3302 for correcting the lighting weight information corresponding to the lighting device with obstruction to obtain actual lighting weight information.

[0145] Because in the hybrid operating room, in addition to the presence of a variety of instruments, there are also a plurality of doctors and nursing staff, the demand for shadowless light in the hybrid operating room is high. It is necessary to correct the lighting weight information corresponding to the obstructed lighting device to a smaller value, so as to avoid the generation of light and shadow.

[0146] Each lighting device and the same target lesion area are sequentially detected to determine whether there is an obstructing object on the irradiation path. When there is an obstructing object, the lighting weight information corresponding to the lighting device with the obstructing object needs to be corrected. It should be noted that when all the lighting devices in the hybrid operating room and the same target lesion area have obstructing objects on the irradiation path, the lighting weight information of each obstructed lighting device does not need to be corrected, but is treated as a special case. That is, each lighting device is directly controlled to emit light to the target lesion area in accordance with the corresponding lighting weight information.

[0147] Secondly, the light blocking detection can be performed in the surgery imaging inspection stage, the light blocking detection can also be performed in the surgery stage, and the light blocking detection can also be performed in the post-surgery treatment stage. However, the light blocking detection is not needed in the surgery idle stage, the light blocking detection is not needed in the boot preparation stage, and the light blocking detection is not needed in the surgery room cleaning stage. Whether the blocking condition between the target lesion area and each lighting device needs to be detected can be determined according to the working mode of the surgery. The precondition of the blocking detection can be set by the person skilled in the art according to the actual situation, and the embodiment is not specifically limited.

[0148] The control module 330 is further configured to control the lighting device to emit light to the target lesion area according to the corresponding actual lighting weight information.

[0149] For example, the lighting device includes a first lighting device, a second lighting device, and a third lighting device. When the first lighting device is blocked from the target lesion area, the second lighting device is blocked from the target lesion area, and the third lighting device is not blocked from the target lesion area, the first lighting device is controlled to emit light to the target lesion area according to the corresponding actual lighting weight information, the second lighting device is controlled to emit light to the target lesion area according to the corresponding actual lighting weight information, and the third lighting device is controlled to emit light to the target lesion area according to the corresponding lighting weight information.

[0150] In an optional embodiment, as shown in Figure 11 The determination module 310 includes:

[0151] The acquisition unit 311 is configured to acquire the human model information and the surgery information of the current surgery.

[0152] The determination unit 312 is configured to determine the target lesion area according to the human model information and the surgery information.

[0153] The surgery information includes at least one of a surgery type and a working mode, and the working mode includes at least one of an idle mode, a boot preparation mode, an imaging inspection mode, a surgery stage mode, a post-surgery treatment mode, and a post-surgery cleaning mode.

[0154] The determination unit 312 identifies the human structure of the patient from the human model information acquired by the acquisition unit 311, and identifies the important part of the human body according to the human structure. Whether the target lesion area needs to be determined is determined according to the working mode in the surgery information. When the working mode is the idle mode, the boot preparation mode, the post-surgery cleaning mode, and the shutdown mode, the target lesion area does not need to be determined. When the working mode is the imaging inspection mode, the post-surgery stage mode, and the post-surgery treatment mode, the target lesion area needs to be determined.

[0155] When the target lesion area needs to be determined, the position of the target lesion area of the patient in the current surgery is determined in combination with the type of surgery in the surgery information. For example, if the type of surgery in the surgery information is heart surgery, the target lesion area is located at the position of the heart of the patient; if the type of surgery in the surgery information is liver surgery, the target lesion area is located at the position of the liver of the patient; if the type of surgery in the surgery information is abdominal surgery, the target lesion area is located at the position of the abdomen of the patient.

[0156] In this embodiment, the control system further includes:

[0157] The intensity determination module 3303 is configured to determine light intensity information according to the surgery information.

[0158] In different working modes, the composite operating room has different requirements for light intensity. For example, there is no requirement for light intensity in the idle mode stage, weak light intensity is required in the start-up preparation mode stage, weak light intensity is required in the image examination mode stage, strong light intensity is required in the surgery stage mode, relatively strong light intensity is required in the post-surgery processing mode stage, medium light intensity is required in the post-surgery cleaning mode stage, and weak light intensity is required in the shutdown stage.

[0159] It should be noted that the positions of the target lesion areas of different types of surgery are different, and the requirements for light intensity are also slightly different. For example, the required light intensity is relatively strong when the target lesion area is located at the position of the heart of the patient; the required light intensity is medium when the target lesion area is located at the position of the liver of the patient; and the required light intensity is medium when the target lesion area is located at the abdomen of the patient. Those skilled in the art can also set the specific values of the light intensity corresponding to each working mode under different types of surgery according to the actual situation, and the range of the light intensity is not specifically limited in this embodiment.

[0160] The annotation processing is performed in advance according to the working mode and the lesion area to obtain a graph including light intensity values. The light intensity information in the graph can be adaptively adjusted according to the actual use requirements and behavior preferences of each composite operating room. This way meets the individualized requirements of each composite operating room for the light intensity of multiple different lighting devices, and can automatically adjust the power or brightness of each lighting device, thereby improving the user experience. After the surgery information is determined, the light intensity information corresponding to the working mode and the target lesion area is selected from the graph.

[0161] The control module 330 specifically includes:

[0162] The power calculation unit 331 is configured to calculate power information of the lighting device according to the light intensity information and the lighting weight information.

[0163] The control unit 332 is configured to control the lighting device to emit light to the target lesion area based on the power information.

[0164] When the light intensity information is determined, the power calculation unit 331 calculates the light intensity information S and the lighting weight information W corresponding to the i th lighting device i According to the fourth calculation formula, the power information S corresponding to the i th lighting device is calculated i . The i th lighting device is controlled to emit light conforming to the power information S i corresponding to the i th lighting device. The calculated power information corresponding to different lighting devices can be different or the same.

[0165] <Formula 4>

[0166]

[0167] The embodiment provides a control system for indoor light. By controlling the lighting device to emit light according to the lighting weight information calculated according to the distance information and the angle information between the target lesion area and the lighting device, the power or brightness of each lighting device can be automatically adjusted, the user is avoided from manually adjusting the lighting parameters of each lighting device in the operating room, the problem of the composite operating room relying on manual adjustment of the shadowless lamp is solved, the intelligent degree of the shadowless lamp in the operating room is improved, the personalized demand of the light intensity of multiple different lighting devices in each composite operating room is met, and the experience of the user is enhanced.
