[0026] The following description, with reference to the accompanying drawings, describes a shadowless lamp focus control system 1 according to an embodiment of the present invention.
[0027] like Figures 1-3 As shown, the shadowless lamp focus control system 1 according to an embodiment of the present invention includes a shadowless lamp 10, a driving device 20, and eye-tracking glasses 30.
[0028] The driving device 20 is connected to the shadowless lamp 10 and is adapted to drive the shadowless lamp 10 to move. The eye-tracking glasses 30 are equipped with an eye-tracking device, which is adapted to track the wearer's eye focus. The eye-tracking device communicates with the driving device 20, and the driving device 20 is adapted to drive the focus of the shadowless lamp 10 to coincide with the eye focus.
[0029] Specifically, the drive device 20 can be a robotic arm with at least three degrees of freedom. Under the drive of the drive device 20, the shadowless lamp 10 can move in multiple directions in space, and the position and illumination angle of the shadowless lamp 10 can be adjusted. The shadowless lamp 10 itself can adjust the brightness and the size of the illumination area.
[0030] During surgery, the surgeon wears eye-tracking glasses 30, which track the surgeon's gaze focus and send the gaze focus information to the drive device 20. The drive device 20 drives the shadowless lamp 10 according to the gaze focus information, so that the focus of the shadowless lamp 10 coincides with the gaze focus, and the surgeon's gaze focus is always kept under the illumination focus of the shadowless lamp 10.
[0031] According to the shadowless lamp focus control system 1 of this utility model embodiment, by setting up eye-tracking glasses 30, the surgeon can wear eye-tracking glasses 30 to track the surgeon's eye focus. By setting up a driving device 20, the driving device 20 is connected to the shadowless lamp 10. The eye-tracking glasses 30 can send eye focus information to the driving device 20. The driving device 20 drives the shadowless lamp 10 according to the eye focus information, so that the focus of the shadowless lamp 10 coincides with the eye focus. This ensures that the surgeon's eye focus is always under the illumination focus of the shadowless lamp 10, maintaining the best lighting effect in the surgical area and improving the reliability of the surgery. Compared with shadowless lamps in related technologies, there is no need for an assistant to manually adjust the position and angle of the shadowless lamp 10, which not only saves manpower but also improves the timeliness and accuracy of the adjustment of the shadowless lamp 10, avoiding the risk of infection introduced by manual adjustment.
[0032] Therefore, the shadowless lamp focus control system 1 according to the present invention can automatically adjust the focus of the shadowless lamp, which has the advantages of saving manpower, good lighting effect, timely and accurate adjustment, and low risk of infection.
[0033] The following description, with reference to the accompanying drawings, describes a shadowless lamp focus control system 1 according to a specific embodiment of the present invention.
[0034] In some specific embodiments of this utility model, such as Figures 1-3 As shown, the shadowless lamp focus control system 1 according to an embodiment of the present invention includes a shadowless lamp 10, a driving device 20, and eye-tracking glasses 30.
[0035] Specifically, such as Figure 1 and Figure 2 As shown, the gaze tracking device includes a front-facing camera 31 and a rear-facing camera 32 (indicated by arrows in the figures for vertical, front-back, and left-right directions). The front-facing camera 31 is located on the front surface of the gaze tracking glasses 30, and the rear-facing camera 32 is located on the rear surface of the gaze tracking glasses 30. Specifically, the front-facing camera 31 can capture images of the area in front of the gaze tracking glasses 30, and the rear-facing camera 32 can capture images of the wearer's pupils. The device determines the position of the wearer's gaze focus in space based on the combination of these two images. This facilitates the tracking of the wearer's gaze focus.
[0036] Advantageously, such as Figure 1 and Figure 2 As shown, there are multiple front-facing cameras 31 spaced apart along the left and right sides, and multiple rear-facing cameras 32 spaced apart along the left and right sides. This allows multiple front-facing cameras 31 to capture images of the front, and multiple rear-facing cameras 32 to capture images of the pupils. By combining the images from multiple cameras, the focal point of the gaze can be determined, reducing judgment errors and improving tracking accuracy.
[0037] More specifically, such as Figure 1 and Figure 2 As shown, the front-facing camera 31 is positioned between the two lenses of the eye-tracking glasses 30 and / or on either side of the two lenses, while the rear-facing camera 32 is positioned above the lenses of the eye-tracking glasses 30. This arrangement facilitates the placement of the front-facing camera 31 and the rear-facing camera 32, allowing multiple front-facing cameras 31 and multiple rear-facing cameras 32 to be staggered by a certain distance in the left-right direction, and also avoids interference between the cameras and the lenses, thus ensuring the wearer's field of vision.
[0038] Furthermore, the rear camera 32 is adapted to detect the position and size of the wearer's pupils. This makes it easier to track the wearer's gaze focus based on the position and size of their pupils.
[0039] For example, when the wearer moves their head, the image captured by the front-facing camera 31 changes, the position and size of the wearer's pupils change, and the wearer's focal point of vision changes within the range of the image captured by the front-facing camera 31. Thus, the position of the wearer's focal point of vision in space can be determined based on the combination of the two images.
[0040] Figure 1 and Figure 2 A shadowless lamp focus control system 1 according to some examples of the present invention is shown. For example... Figure 1 and Figure 2As shown, the eye-tracking glasses 30 are equipped with a controller 33, which is adapted to convert the gaze focus tracked by the eye-tracking glasses 30 into coordinates in a spatial coordinate system. Specifically, the controller 33 can combine the images from the front camera 31 and the rear camera 32 to obtain the position of the wearer's gaze focus, establish a spatial coordinate system, and convert the position of the gaze focus into coordinates in the spatial coordinate system. This facilitates the conversion and transmission of the gaze focus position information to the driving device 20.
[0041] Advantageously, the controller 33 is also adapted to generate a confidence level for the coordinates. This eliminates excessive movement of the focal point due to errors or head movements, improving the accuracy and reliability of the output data.
[0042] More advantageously, the eye-tracking glasses 30 are also equipped with an inertial measurement unit, which is electrically connected to the controller 33. This allows the inertial measurement unit to detect head movements, and the detection results of the inertial measurement unit can be combined when generating the eye focus coordinates to avoid unnecessary head movements interfering with the eye focus.
[0043] Specifically, such as Figure 2 As shown, the eye-tracking glasses 30 are equipped with a first wireless communication device 34, and the driving device 20 is equipped with a second wireless communication device. The first wireless communication device 34 is adapted to communicate wirelessly with the second wireless communication device. This facilitates wireless communication between the eye-tracking glasses 30 and the driving device 20, avoiding interference from wired connections on the movement range of the eye-tracking glasses 30.
[0044] More specifically, such as Figure 1 As shown, the eye-tracking glasses 30 are equipped with a battery 35, which is electrically connected to the eye-tracking device. This allows the battery 35 to power the eye-tracking glasses 30, avoiding interference from wired power supply to the range of motion of the eye-tracking glasses 30.
[0045] Specifically, the rear camera 32 captures the position and size of the aperture. The gaze direction is calculated using a PCCR (Programmable Probe-Controlled Reflection) algorithm, and head movement interference is eliminated by combining this with detection data from the inertial measurement unit. The controller 33 processes the detection signal, performing noise reduction and coordinate mapping. The output data format includes the target focus coordinates (X, Y, Z), confidence level (0-1), and timestamp (accuracy 1ms), with a refresh rate greater than or equal to 120Hz.
[0046] Other configurations and operations of the shadowless lamp focus control system 1 according to the embodiments of the present invention are known to those skilled in the art and will not be described in detail here.
