[0033] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings. In this specification, the same or similar reference numerals indicate the same or similar components. The following description of the embodiments of this utility model with reference to the accompanying drawings is intended to explain the overall inventive concept of this utility model and should not be construed as a limitation thereof.

[0034] With the development of technology and the increase in people's needs, the structure of camera lenses is becoming more and more complex, with more and more lenses. The number of times light passes through the lens-air-lens also increases, making it more and more difficult to remove glare.

[0035] It's not just lenses that pose a risk of glare; sensors also have multiple layers of glass filters / lenses.

[0036] A camera sensor is not a simple component, but a complex optical module. A CMOS sensor, itself a large-scale semiconductor composed of millions of photodiodes, does not have the ability to collect colors. Therefore, a Bayer array filter is needed to allow each photodiode to sample the intensity of light information for a specific color. Secondly, the sensor can also collect infrared light, which is invisible to the human eye and affects exposure, so an IR filter is added. To prevent moiré patterns, many camera manufacturers also add a low-pass filter, sacrificing some sharpness to ensure that moiré patterns are not captured when shooting high-frequency details. Finally, to increase light transmittance, fine, gapless microlenses are added, and a sensor protective glass is added to protect all the filters mentioned above. This results in 4-5 layers of filters / lenses on the front of the sensor, which, under certain conditions, can also cause glare.

[0037] Glare can affect the range and accuracy of data acquisition. Therefore, navigation devices need to be glare-proof and capture spatial information of the patient's clothing over a wide range, with a large capture angle and high accuracy.

[0038] To address the aforementioned problems, this application provides a camera assembly 001. Figure 1 An appearance rendering of one embodiment of the camera assembly provided in this application. Figure 2 An exploded view of one embodiment of the camera assembly provided in this application. Figure 3 A partial exploded view of one embodiment of the camera assembly provided in this application, such as... Figures 1-3 As shown, the camera assembly 001 includes: a camera 10, a fixing member 20, and a camera housing 30. The camera 10 is fixed inside the camera housing 30 by the fixing member 20.

[0039] The camera housing 30 includes a first housing 31 and a second housing 32. The first housing 31 is fixed to the side of the second housing 32 that is adapted to the camera lens. The first housing 31 has an opening 311 adapted to the camera 10. The edge of the opening 311 is chamfered α, with the chamfer α ranging from 90° to 180°, preferably 120°. In specific implementation, the size of the opening 311 must avoid the camera's LED fill light, and it cannot be too large to achieve waterproof and dustproof purposes. The chamfer setting can meet the navigation viewing angle requirements and prevent glare.

[0040] In one embodiment, the second housing 32 includes an upper housing 321 and a lower housing 322. The fastener is fixed to the lower housing 322, and the upper housing 321 and the lower housing 322 are fixed by snap-fit. The interior of the upper housing 321 and the lower housing 322 is provided with mounting holes adapted to other components. In addition, a limiting device (not shown) may be provided on the inner side of the first housing 31 for limiting and fixing the edge of the camera 10, thereby fixing the camera 10 in the housing.

[0041] In a specific implementation, the camera 10 can be an infrared camera or a structured light camera. Numerous grounding vias are set on the IR fill light PCB board of the camera, including around the coil, around the outer circumference of the PCB board, and around the IR fill light. Setting grounding vias can significantly reduce grounding resistance, improve the uniformity and effectiveness of grounding, and significantly improve the avoidance of radiated emissions and the provision of a path for electrostatic discharge.

[0042] In one embodiment, the camera assembly 001 further includes a first counterweight 41 and a second counterweight 42. The first counterweight 41 is fixed to the upper housing 321, and the second counterweight 42 is fixed to the lower housing 322. A tapered groove 43 is provided on the contact surface between the first counterweight 41 or the second counterweight 42 and the camera cable. The counterweights ensure that the camera assembly 001 can remain at any desired position without rebound, meeting the minimum mass requirement for arm suspension. The tapered groove 43 on the counterweights facilitates cable passage and secures the cable, making the camera 10 more stably fixed.

[0043] In one embodiment, the fixing member 20 is Z-shaped, and right-angled side plates are provided on both sides of the fixing member 20. The camera 10 is fixed in the housing by the fixing member 20, which can ensure the stability of the camera 10. The fixing member 20 is fixed in the housing by screws. In addition, the camera assembly 001 also includes a thermal pad 50, which is disposed between the camera 10 and the fixing member 20. In specific implementations, a thermally conductive silicone pad can be selected, which can play a role in mechanical cushioning and heat conduction, so that the camera 10 can maintain thermal stability.

[0044] In one embodiment, to further stabilize the camera and prevent it from being pulled during the movement of the support arm, which could cause deformation of the internal structure of the camera 10 and affect the positioning accuracy of the camera 20, the camera assembly 001 further includes a limiting member 60 to fix the camera's cable to the housing. Specifically, the limiting member 60 includes a saddle clip 61 and a heat shrink tubing 62 for fixing the adapter cable.

[0045] The camera assembly of this application is anti-glare and can capture spatial information of the patient's clothing over a wide range, with a large capture angle and high accuracy. Furthermore, the camera assembly provided in this application, through the use of fixing components, makes the overall camera more stable.

[0046] This application also provides a camera trolley 002, such as Figure 4 As shown, it includes a chassis assembly 70, a lifting assembly 80, a support arm assembly 90, and the aforementioned camera assembly 001;

[0047] The support arm assembly 90 includes a first support arm 901 and a second support arm 902, which are connected by a pivot. The other end of the first support arm 901 is connected to the camera assembly 001, and the other end of the second support arm 902 is connected to the lifting assembly 80. In specific implementations, the support arm assembly 90 may include at least one support arm, the size and number of which can be adapted to specific needs for more flexible movement and adjustment. If there are more than two support arms, they can be raised and extended by pivot connection, enabling vertical and horizontal movement, thus expanding the range and angle of image acquisition and providing greater flexibility. The form of the pivot is not limited to that shown in the diagram.

[0048] A camera assembly 001 is disposed on one end of the support arm assembly 90 and is pivotable at one end of the support arm assembly 90.

[0049] A lifting assembly 80, one end of which is connected to one end of the support arm assembly 90, can adjust the height of the support arm assembly 90 or the camera assembly 001 through its own lifting movement. The specific connection method and structure are not specifically limited.

[0050] A chassis assembly 70, the upper end of which is fixedly connected to the other end of the lifting assembly 80. Alternatively, the chassis assembly 70 can also be configured as a wheel.

[0051] In one embodiment, a first handle 903 is further provided between the camera assembly 001 and the support arm assembly 90, and is fixed by a connector. A second handle 801 is provided on the lifting assembly 80. Both the first and second handles are made of non-metallic materials. If the first handle 903 or the second handle 801 is made of metal, it is easy to form a capacitor-like structure with other components, resulting in discharge and leakage points, leading to arcing. Using non-metallic materials, such as plastic handles, or applying an insulating coating, avoids arcing. During use, the first handle 903 or the second handle 801 allows for easier and more convenient dragging of the camera assembly 001 or the camera carriage 002 for overall position adjustment.

[0052] In one embodiment, the camera carriage 002 further includes a controller (not shown) or a display 100. The controller of the camera carriage can be adapted to operate with other magnetic stimulation devices for image acquisition and navigation, while the display is used for images or other navigation interfaces that need to be shown. The camera carriage can operate independently, thus broadening its application scenarios.

[0053] Figure 5 A schematic diagram of one embodiment of the medical system provided in this application is shown below. Figure 5 The medical system 01 shown includes a main control carriage 003, a camera carriage 002, and a stimulation coil 004. The stimulation coil 004 is connected to the main control carriage 003 through a pipeline. The main control carriage 003 is equipped with a control module (not shown) for providing stimulation parameters to the camera carriage 002 and the stimulation coil 004.

[0054] The stimulation coil 004 can be a device with a magnetic stimulation generating unit (e.g., a component that can output magnetic energy), or it can be a positioning coil without a magnetic stimulation generating unit, such as electrical stimulation, ultrasonic stimulation, etc.

[0055] The stimulation coil 004 and the main control carriage 003 can transmit signals. In one example, signal transmission can be achieved via local area network, wide area network, Wi-Fi, mobile network, Bluetooth, wired network, data cable, etc. In one example, the signal can be a communication signal, data signal, command signal, control signal, electrical signal (including digital and analog signals), optical signal, etc., and the signal type is not limited here. In one example, the stimulation coil 004 can be a true stimulation coil or a combined true and false stimulation coil.

[0056] In one embodiment, the camera on the camera carriage 002 tracks and positions the stimulation coil 004 via a navigation device. In use, the camera on the camera carriage 002 identifies the stimulation coil 004 and transmits the data of the identified stimulation coil 004 (e.g., at least one of image data, position data, shape data, color data, image data, three-dimensional data, etc.) to the main control carriage 003 to track and position the stimulation coil 004. The camera configured on the camera carriage 002 can be an infrared camera or a structured light camera, as long as it can provide depth information of the identified, tracked, or positioned object. This example is merely illustrative and should not be construed as a limitation of this disclosure by those skilled in the art.

[0057] In one example, the main control carriage 003 can transmit control signals to the stimulation coil 004 or the camera carriage 002, etc. For example, it can send stimulation parameters for adjusting the target point (frequency, pulse intensity, stimulation duration, stimulation period, etc.) and stimulation parameters for simulating a real stimulation coil (e.g., vibration frequency, vibration duration, vibration period, volume, type, frequency, etc. of the sound from the simulated real stimulation coil).

[0058] In one example, the stimulation coil 004, camera carriage 002, and other devices or equipment are equipped with a controller, control circuit, or control chip so that the stimulation coil 004, camera carriage 002, and other devices or equipment can communicate with the main control carriage 003 (e.g., transmit data, transmit signals, etc.).

[0059] This disclosure allows the medical system 01 to track, locate, and identify target points or areas requiring tracking and location in subjects suffering from diseases such as autism, depression, obsessive-compulsive disorder, affective disorders, epilepsy, Alzheimer's disease, and brain injury. It can also track and locate stimulation coils 004, etc. The medical system 01 can also stimulate or modulate the nerves of target points in subjects suffering from diseases such as autism, depression, obsessive-compulsive disorder, affective disorders, epilepsy, Alzheimer's disease, and brain injury. Furthermore, it can provide real-time navigation during the stimulation of target points or the manipulation of the subject (e.g., guiding the placement, orientation, and distance of stimulation coils 004, etc.).

[0060] The camera assembly and camera carriage disclosed in this application have at least one of the following advantages:

[0061] (1) The camera component provided in this application can prevent glare and capture spatial information of the patient wearing the device over a large range, with a large capture angle and accuracy.

[0062] (2) The camera assembly provided in this application can make the camera more stable by using a fixed component.

[0063] (3) The camera trolley provided in this application has its outriggers connected by pivots, allowing for lifting and stretching, and enabling vertical and horizontal movement, thus expanding the range and angle of image acquisition and making it more flexible.

[0064] While some embodiments of the overall inventive concept of this application have been shown and described, those skilled in the art will understand that changes may be made to these embodiments without departing from the principles and spirit of the overall inventive concept of this application, the scope of which is defined by the claims and their equivalents.
