Detailed Description
The invention is further illustrated by means of the following examples, which are not intended to limit the scope of the invention.
Example 1
As shown in fig. 1, the control method of indoor light of the present embodiment includes:
s110, determining a target focal zone of the patient.
S120, calculating illumination weight information corresponding to the illumination equipment according to the distance information and/or the angle information between the target focus area and the illumination equipment.
S130, controlling the lighting equipment to send out light rays conforming to the corresponding lighting weight information to the target focus area.
The compound operating room has more functions and different requirements on light intensity in different working modes. For example, the pre-operative examination phase does not require particularly bright lights, and the operative progression phase requires the provision of shadowless lights. Thus, in order to meet the flexible surgical needs, the complex operating room generally includes various instruments, such as DSA radiography machines, various coaching devices, and flexible rotating hospital beds.
For the above step S110, the complex operating room is composed of a plurality of illumination devices (L 1 、L 2 、L 3 …，L i ) And a visual detection camera, a sickbed and software/hardware equipment matched with an operating room. In order to acquire a wide-area view angle, one vision inspection camera is installed at an upper corner position of a complex operating room, and when a plurality of vision inspection cameras exist, the application form of the vision inspection camera can be appropriately adjusted. The vision detection camera installed in the composite operating room shoots images in the composite operating room, so that the position information of a sickbed, the position information of a patient on the sickbed and the human body form information of the patient on the sickbed are detected in real time, and then the target focus area of the patient is automatically identified according to the detected result and the current operation type.
For example, if the current surgical type is cardiac surgery, the cardiac region of the patient is automatically identified based on the detected position information of the patient's bed, the patient's position information, the patient's body morphology information, and the cardiac surgical type. The position information of the sickbed, the position information of the patient on the sickbed and the human body form information of the patient on the sickbed are automatically detected in real time through the vision detection camera, so that the accuracy of identifying the target focus area of the patient can be effectively improved, and the intelligent degree of indoor light control is enhanced.
For the above step S120, each lighting device of the lighting device set of the complex operating room has different lighting weight information for distributing the corresponding output power of each lighting device. When a patient performs an operation, it is desirable to create a shadowless light in the complex operating room. The closer to the angle of the vertical irradiation target focal zone, the better the effect of the light. In other words, the closer the angle of incidence of the light ray into the target focal zone is, the better the lighting effect is, and the greater the illumination weight information corresponding to the illumination device closer to 0 degrees is.
According to the distance information between the vision detection camera and each lighting device and the distance information between the vision detection camera and the target focus area, calculating to obtain the distance information between the target focus area and each lighting device, and then according to the distance information, obtaining the angle information between the target focus area and each lighting device, and carrying out trigonometric function solving on the angle information to obtain the lighting weight information corresponding to each lighting device. It should be emphasized that the angle information indicates the angle between the line connecting the target focal zone and each illumination device and the vertical.
In practical applications, other calculation methods may be used, and the calculation method is not limited to the calculation method of the trigonometric function solution for example, and the calculation method of the illumination weight information corresponding to the angle information calculation illumination device is not limited in this embodiment.
For the above step S130, the lighting apparatuses include a first lighting apparatus, a second lighting apparatus, and a third lighting apparatus. The first lighting equipment is controlled to emit light rays which accord with the corresponding first lighting weight information to the target focus area, the second lighting equipment is controlled to emit light rays which accord with the corresponding second lighting weight information to the target focus area, and the third lighting equipment is also controlled to emit light rays which accord with the corresponding third lighting weight information to the target focus area. The first illumination weight information, the second illumination weight information, and the third illumination weight information may be the same or different.
When the indoor lamplight control method provided by the embodiment of the invention is used, after the target focal zone is determined, each lighting device is immediately controlled in a preset period of time, and simultaneously, the lighting device automatically emits the light consistent with the calculated lighting weight information to the target focal zone, so that the composite operating room is not required to rely on manual operation or is set in advance according to the operation starting time, and the user experience is improved.
In an alternative embodiment, as shown in fig. 2, step S120 specifically includes:
s121, detecting first distance information between the target focus area and the camera.
S122, obtaining second distance information between the lighting equipment and the camera; the lighting device and the camera are respectively positioned at different positions in the operating room.
S123, calculating illumination weight information corresponding to the illumination equipment according to the first distance information and the second distance information.
The visual inspection camera may be a normal visual inspection camera including a camera head. The common vision detection camera is low in price and does not need special equipment such as a sensor, so that the cost for determining the target focus area of the patient is greatly reduced. For the above steps S121 to S123, when the vision inspection camera is mounting the correction, it is necessary to measure the spatial distance information between each illumination device and the vision inspection camera. As shown in fig. 3, the composite operating room is provided with a camera, a hospital bed and i illumination devices, each of which is located at a different position above the composite operating room. The number of illumination devices at least needs to meet the power requirements under different surgical models, and the illumination devices are generally distributed on the ceiling of the composite operating room at equal intervals, and are arranged around the sickbed in the vertical direction as a preferred scheme.

M is M l 、M h 、M w Representing second distance information between the target focus zone and the camera, M l Representing the length value of the target focus zone and the camera under the three-dimensional space coordinate system, M h Representing the height value of the target focus zone and the camera under the three-dimensional space coordinate system, M w And the width value of the target focus area and the camera under the three-dimensional space coordinate system is represented.
In an alternative embodiment, as shown in fig. 4, step S123 specifically includes:
s1231, third distance information between the illumination device and the target focus interval is calculated according to the first distance information and the second distance information.
S1232, calculating angle information of the illumination device and the target lesion interval based on the third distance information, the first distance information, and the second distance information.
And S1233, calculating illumination weight information according to the angle information.
For the above steps S1231-S1233, third distance information P between the ith illumination device and the target focal zone is calculated from the first distance information and the second distance information according to the following first calculation formula i . As shown in FIG. 4, according to P in the third distance information i H in the first distance information i M in the second distance information h Calculating the angle information theta between the ith lighting equipment and the target focus interval according to the following second calculation formula i .

< formula 2>
< formula 3>
In an alternative embodiment, as shown in fig. 6, the lighting device includes a plurality of lighting devices, and before step S130, the control method further includes:
s1301, detecting whether shielding exists between the target focus area and each lighting device; if yes, go to step S1302.
S1302, the illumination weight information corresponding to the illumination equipment with the shielding is corrected to obtain the actual illumination weight information.
Because there are a plurality of doctors and carers in addition to a plurality of instruments in the complex operating room, the demands for shadowless light in the complex operating room are high. The illumination weight information corresponding to the blocked illumination device needs to be corrected to a smaller value so as to avoid the occurrence of shadows.
As shown in fig. 7, it is sequentially detected whether or not an occluding object (a cube is shown in fig. 7) exists on the irradiation path between each illumination device and the same target focal zone, and when the occluding object exists, the illumination weight information corresponding to the illumination device with the occluding object needs to be corrected. When an object is blocked on the irradiation path between all the illumination devices and the same target focal zone in the composite operating room, the illumination weight information of each illumination device with the blocking is not required to be corrected, and the illumination weight information is treated as a special case. That is, the automatic default target focal zone and all the lighting devices are not shielded, and each lighting device is directly controlled to emit light rays conforming to the corresponding lighting weight information to the target focal zone.
Secondly, can carry out the light and shelter from the detection at the operation image inspection stage, also can carry out the light detection and shelter from at the operation stage, can also carry out the light detection and shelter from at the postoperative processing stage. But do not need to carry out light detection shielding in the operation idle stage, do not need to carry out light detection shielding in the startup preparation stage, and do not need to carry out light detection shielding in the operation room cleaning stage. Whether the shielding condition between the target focus area and each lighting device needs to be detected can be judged according to the operation mode, a person skilled in the art can set the precondition of shielding detection according to the actual condition, and the embodiment is not particularly limited.
The step S130 specifically includes:
s131, controlling the lighting equipment to send out light rays which accord with the corresponding actual lighting weight information to the target focus area.
The lighting device includes a first lighting device, a second lighting device, and a third lighting device. When the shielding exists between the first lighting equipment and the target focus area, the shielding exists between the second lighting equipment and the target focus area, and the shielding does not exist between the third lighting equipment and the target focus area, the first lighting equipment is controlled to emit light rays of corresponding actual lighting weight information to the target focus area, the second lighting equipment is controlled to emit light rays of corresponding actual lighting weight information to the target focus area, and the third lighting equipment is controlled to emit light rays of corresponding lighting weight information to the target focus area.
In an alternative embodiment, as shown in fig. 8, step S110 specifically includes:
s111, collecting human body model information and operation information of the current operation.
S112, determining a target focus area according to the human body model information and the operation information.
The operation information comprises an operation type and a working mode, wherein the working mode comprises at least one of an idle mode, a startup preparation mode, an image inspection mode, an operation stage mode, a postoperative treatment mode and a postoperative cleaning mode.
For the steps S111-S112, the human body structure of the patient is identified from the acquired human body model information, the important parts of the human body are identified according to the human body structure, and whether the target focal zone needs to be determined is determined according to the working mode in the operation information. And under the working modes of idle mode, startup preparation mode, postoperative cleaning mode and shutdown mode, the target focus area is not required to be determined. In the case where the operation mode is an image inspection mode, a post-operation stage mode, and a post-operation treatment mode, it is necessary to determine a target focal zone.
When the target focal zone needs to be determined, the position of the target focal zone of the patient currently operated is determined by combining the operation type in the operation information. For example, if the type of surgery in the surgical information is cardiac surgery, the target focal region is located at a cardiac location in the patient; if the operation type in the operation information is liver operation, the target focus area is positioned at the liver position of the patient; if the type of surgery in the surgical information is abdominal surgery, the target focal zone is located at the abdominal position of the patient.
In this embodiment, the control method further includes:
s1303, determining light intensity information according to the operation information.
Under different working modes, the requirements of the composite operating room on the light intensity are different. For example, there is no light intensity requirement in the idle mode, weak light intensity is required in the power-on preparation mode, weak light intensity is required in the image inspection mode, strong light intensity is required in the operation mode, medium light intensity is required in the post-operation treatment mode, and weak light intensity is required in the shutdown mode.
It should be noted that the positions of the target focal regions of different surgical types are different, and the requirements for the light intensity are slightly different. For example, the intensity of light required for a target focal region to be located at a heart site of a patient is relatively high; the target focal area is positioned at the liver position of the patient and has moderate light intensity; the target focal area is located on the abdomen of the patient with moderate light intensity. Those skilled in the art can also set specific values of the light intensity corresponding to each working mode under different operation types according to actual conditions, and the range of the light intensity in this embodiment is not particularly limited.
Marking processing is performed in advance according to the working mode and focal zone generation so as to obtain a chart comprising light intensity values, and the light intensity information in the chart can be adaptively adjusted according to the actual use requirement and behavior preference of each composite operating room. The mode meets the personalized requirements of each composite operating room on the light intensity of a plurality of different lighting devices, and the power or the brightness of each lighting device can be automatically adjusted, so that the experience of a user is improved. After the surgical information is determined, light intensity information corresponding to the mode of operation and the target focal zone is screened from the chart.
The step S130 specifically includes:
s132, calculating power information of the lighting equipment according to the light intensity information and the lighting weight information.
S133, controlling the lighting equipment to emit light to the target focus area based on the power information.
For the above steps S132-S133, after the light intensity information is determined, the light intensity information S and the illumination weight information W corresponding to the ith illumination device are determined i Calculating power information S corresponding to the ith lighting equipment according to a fourth calculation formula i . Controlling the ith lighting equipment to send out the information S conforming to the power to the target focus area i Is a light source, and is a light source. The power information calculated for different lighting devices may be different or the same.
< formula 4>
In an alternative embodiment, as shown in fig. 9, a light conditioning system for a complex operating room includes an indoor software control system, a visual inspection camera, a light controller, and a lighting light fixture including a plurality of lighting devices. The indoor software control system extracts the working mode from the operation information generated by the external instruction input by the user and sends the working mode to the light controller. The vision detection camera detects the patient on the patient bed in real time, automatically identifies the target focus area according to the detected result and the current operation mode, and sends the position information of the target focus area to the light controller.
The light controller calculates different illumination weight information of different illumination devices according to first distance information between the target focus area and the visual detection camera and second distance information between each illumination device and the visual detector. The light intensity information of each focus area under each working mode is stored in the storage module of the light controller in advance, the target light intensity information is obtained by looking up a table from the storage module based on the target focus area and the working mode, and the power information of each lighting device is calculated according to the target light intensity information and the lighting weight information. And finally controlling each lighting lamp group to emit light corresponding to the power information, so as to realize intelligent adjustable shadowless lighting effect.
It should be noted that, the storage module of the light controller supports the user to configure the light intensity information in each working mode. The user can pre-configure the light intensity information according to the actual use requirement and the behavior preference of each composite operating room and then store the light intensity information in the storage module, the follow-up operation is performed on the light intensity information in each working mode according to the pre-configuration of the user, and the user can randomly adjust the light intensity information in each working mode. The mode meets the personalized requirements of each composite operating room on the light intensity of a plurality of different lighting devices, and the power or the brightness of each lighting device can be automatically adjusted, so that the experience of a user is improved.
The embodiment provides a control method of indoor lamplight, which can automatically adjust the power or brightness of each lighting device by controlling the lighting device to emit the light of the lighting weight information calculated according to the distance information and/or the angle information between a target focus area and the lighting device, so that the lighting parameters of each lighting device in an operating room are prevented from being manually adjusted by a user, and the problem that a composite operating room relies on manual adjustment of shadowless lamps is solved; the intelligent degree of the shadowless lamp of the operating room is improved; the personalized requirements of each composite operating room on the light intensity of a plurality of different lighting devices are also met, and the experience of users is enhanced.

The compound operating room has more functions and different requirements on light intensity in different working modes. For example, the pre-operative examination phase does not require particularly bright lights, and the operative progression phase requires the provision of shadowless lights. Thus, in order to meet the flexible surgical needs, the complex operating room generally includes various instruments, such as DSA radiography machines, various coaching devices, and flexible rotating hospital beds.
The complex operating room is composed of a plurality of lighting devices (L 1 、L 2 、L 3 …，L i ) And a visual detection camera, a sickbed and software/hardware equipment matched with an operating room. In order to acquire a wide-area view angle, one vision inspection camera is installed at an upper corner position of a complex operating room, and when a plurality of vision inspection cameras exist, the application form of the vision inspection camera can be appropriately adjusted. The image in the complex operating room is photographed by the vision inspection camera installed in the complex operating room, so that the position information of the patient on the patient's bed, and the human body form information of the patient on the patient's bed are inspected in real time, and the determination module 310 automatically identifies the target focal zone of the patient according to the inspected result and the current operation type.
For example, if the current surgical type is cardiac surgery, the cardiac region of the patient is automatically identified based on the detected position information of the patient's bed, the patient's position information, the patient's body morphology information, and the cardiac surgical type. The position information of the sickbed, the position information of the patient on the sickbed and the human body form information of the patient on the sickbed are automatically detected in real time through the vision detection camera, so that the accuracy of identifying the target focus area of the patient can be effectively improved, and the intelligent degree of indoor light control is enhanced.
Each lighting device of the lighting device set of the composite operating room has different lighting weight information for assigning a corresponding output power to each lighting device. When a patient performs an operation, it is desirable to create a shadowless light in the complex operating room. The closer to the angle of the vertical irradiation target focal zone, the better the effect of the light. In other words, the closer the angle of incidence of the light ray into the target focal zone is, the better the lighting effect is, and the greater the illumination weight information corresponding to the illumination device closer to 0 degrees is.
According to the distance information between the vision detection camera and each lighting device and the distance information between the vision detection camera and the target focus area, the distance information between the target focus area and each lighting device is calculated, then the angle information between the target focus area and each lighting device is obtained according to the distance information, and the calculating module 320 performs trigonometric function solving on the angle information to obtain the lighting weight information corresponding to each lighting device. It should be emphasized that the angle information indicates the angle between the line connecting the target focal zone and each illumination device and the vertical.
In practical applications, other calculation methods may be used, and the calculation method is not limited to the calculation method of the trigonometric function solution for example, and the calculation method of the illumination weight information corresponding to the angle information calculation illumination device is not limited in this embodiment.
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 focal zone, the control module 330 controls the second lighting device to emit light rays conforming to the corresponding second lighting weight information to the target focal zone, and the control module 330 also controls the third lighting device to emit light rays conforming to the corresponding third lighting weight information to the target focal zone. The first illumination weight information, the second illumination weight information, and the third illumination weight information may be the same or different.
When the indoor lamplight control system provided by the embodiment of the invention is used, after the determining module determines the target focus area, the control module immediately controls each lighting device to automatically send the light consistent with the calculated lighting weight information to the target focus area within the preset period, and the composite operating room is not required to rely on manual operation or is set in advance according to the operation starting time, so that the user experience is improved.
In an alternative embodiment, as shown in fig. 11, the computing module 320 specifically includes:
the detecting unit 321 is configured to detect first distance information between the target focal zone and the camera.
An obtaining unit 322, configured to obtain second distance information between the lighting device and the camera; the lighting device and the camera are respectively positioned at different positions in the operating room.
A calculating unit 323, configured to calculate illumination weight information corresponding to the illumination device according to the first distance information and the second distance information.
The visual inspection camera may be a normal visual inspection camera including a camera head. The common vision detection camera is low in price and does not need special equipment such as a sensor, so that the cost for determining the target focus area of the patient is greatly reduced. When the vision inspection camera is mounted with the correction, it is necessary to measure the spatial distance information between each illumination device and the vision inspection camera. The composite operating room is provided with a camera, a sickbed and i lighting devices, and each lighting device and the camera are respectively positioned at different positions above the composite operating room. The number of illumination devices at least needs to meet the power requirements under different surgical models, and the illumination devices are generally distributed on the ceiling of the composite operating room at equal intervals, and are arranged around the sickbed in the vertical direction as a preferred scheme.

In an alternative embodiment, as shown in fig. 11, the lighting device includes a plurality of lighting devices, and the control system further includes:
the detection module 3301 is used for detecting whether shielding exists between the target focus area and each lighting device; if so, the correction module 3302 is invoked.
And the correction module 3302 is used for correcting the illumination weight information corresponding to the illumination equipment with the shielding to obtain the actual illumination weight information.
Because there are a plurality of doctors and carers in addition to a plurality of instruments in the complex operating room, the demands for shadowless light in the complex operating room are high. The illumination weight information corresponding to the blocked illumination device needs to be corrected to a smaller value so as to avoid the occurrence of shadows.
And detecting whether a shielding object exists on an irradiation path between each lighting device and the same target focus area in sequence. When an occluding object exists, the illumination weight information corresponding to the illumination equipment with the occluding object needs to be corrected. When an object is blocked on the irradiation path between all the illumination devices and the same target focal zone in the composite operating room, the illumination weight information of each illumination device with the blocking is not required to be corrected, and the illumination weight information is treated as a special case. That is, each illumination device is directly controlled to emit light rays conforming to the corresponding illumination weight information to the target focal zone.
Secondly, can carry out the light and shelter from the detection at the operation image inspection stage, also can carry out the light detection and shelter from at the operation stage, can also carry out the light detection and shelter from at the postoperative processing stage. But do not need to carry out light detection shielding in the operation idle stage, do not need to carry out light detection shielding in the startup preparation stage, and do not need to carry out light detection shielding in the operation room cleaning stage. Whether the shielding condition between the target focus area and each lighting device needs to be detected can be judged according to the operation mode, a person skilled in the art can set the precondition of shielding detection according to the actual condition, and the embodiment is not particularly limited.
The control module 330 is further configured to control the illumination device to emit light rays corresponding to the actual illumination weight information to the target focal zone.
The lighting device includes a first lighting device, a second lighting device, and a third lighting device. When the shielding exists between the first lighting equipment and the target focus area, the shielding exists between the second lighting equipment and the target focus area, and the shielding does not exist between the third lighting equipment and the target focus area, the first lighting equipment is controlled to emit light rays of corresponding actual lighting weight information to the target focus area, the second lighting equipment is controlled to emit light rays of corresponding actual lighting weight information to the target focus area, and the third lighting equipment is controlled to emit light rays of corresponding lighting weight information to the target focus area.

The operation information comprises an operation type and a working mode, wherein the working mode comprises at least one of an idle mode, a startup preparation mode, an image inspection mode, an operation stage mode, a postoperative treatment mode and a postoperative cleaning mode.
The determining unit 312 identifies the human body structure of the patient from the human body model information acquired by the acquisition unit 311, and identifies important parts of the human body according to the human body structure. Judging whether the target focus area needs to be determined according to the working mode in the operation information. And under the working modes of idle mode, startup preparation mode, postoperative cleaning mode and shutdown mode, the target focus area is not required to be determined. In the case where the operation mode is an image inspection mode, a post-operation stage mode, and a post-operation treatment mode, it is necessary to determine a target focal zone.
When the target focal zone needs to be determined, the position of the target focal zone of the patient currently operated is determined by combining the operation type in the operation information. For example, if the type of surgery in the surgical information is cardiac surgery, the target focal region is located at a cardiac location in the patient; if the operation type in the operation information is liver operation, the target focus area is positioned at the liver position of the patient; if the type of surgery in the surgical information is abdominal surgery, the target focal zone is located at the abdominal position of the patient.
In this embodiment, the control system further includes:
the intensity determining module 3303 is used for determining light intensity information according to operation information.
Under different working modes, the requirements of the composite operating room on the light intensity are different. For example, there is no light intensity requirement in the idle mode, weak light intensity is required in the power-on preparation mode, weak light intensity is required in the image inspection mode, strong light intensity is required in the operation mode, medium light intensity is required in the post-operation treatment mode, and weak light intensity is required in the shutdown mode.
It should be noted that the positions of the target focal regions of different surgical types are different, and the requirements for the light intensity are slightly different. For example, the intensity of light required for a target focal region to be located at a heart site of a patient is relatively high; the target focal area is positioned at the liver position of the patient and has moderate light intensity; the target focal area is located on the abdomen of the patient with moderate light intensity. Those skilled in the art can also set specific values of the light intensity corresponding to each working mode under different operation types according to actual conditions, and the range of the light intensity in this embodiment is not particularly limited.

The mode meets the personalized requirements of each composite operating room on the light intensity of a plurality of different lighting devices, and the power or the brightness of each lighting device can be automatically adjusted, so that the experience of a user is improved. After the surgical information is determined, light intensity information corresponding to the mode of operation and the target focal zone is screened from the chart.

a power calculation unit 331 for calculating power information of the illumination device based on the light intensity information and the illumination weight information.
And a control unit 332, configured to control the illumination device to emit light to the target focal zone based on the power information.

Controlling the ith lighting equipment to send out the information S conforming to the power to the target focus area i Is a light source, and is a light source. The power information calculated for different lighting devices may be different or the same.
< formula 4>
