[0036] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
[0037] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.
[0038] The present application provides an optical coordinate data acquisition device, which uses a trigger component to trigger an electronic device to calculate the optical coordinates of a target position in a camera coordinate system. This device enables a user to trigger the electronic device to calculate the optical coordinates of the target position without the aid of an external control device, thereby improving the ease of use of the optical coordinate data acquisition device.
[0039] The optical coordinate data acquisition device provided in the present application may be an optical probe or other similar optical devices, which are used to obtain coordinate data of a target position on a measured object.
[0040] Optionally, the object to be measured may include a surgical instrument, for example, the object to be measured may include a scalpel and a robotic arm of a surgical robot.
[0041] The existing method of using optical coordinate data acquisition equipment is: the user holds the optical coordinate data acquisition device, places the optical coordinate data acquisition device at the target position in a preset posture, and then the camera takes a picture of the optical coordinate data acquisition device to obtain an image. When the calculation process is manually triggered by clicking a specific button on the software interface, a foot switch, or using a remote control, the electronic device calculates the optical coordinates of the target position in the camera coordinate system based on the position coordinates of each optical marker component in the currently acquired image and the relative position relationship between the tip point placed at the target position and each optical marker component.
[0042] The method of using the optical coordinate data acquisition device of the present application is as follows: the user holds the optical coordinate data acquisition device and places the optical coordinate data acquisition device at the target position in a preset posture, and then the camera takes a picture of the optical coordinate data acquisition device to obtain an image. When the user operates the trigger component to trigger the calculation process, the electronic device calculates the optical coordinates of the target position in the camera coordinate system based on the position coordinates of each optical marker component in the currently acquired image and the relative position relationship between the tip point placed at the target position and each optical marker component. In this method of use, the user can trigger the electronic device to calculate the optical coordinates of the target position without the help of an external control device.
[0043] The optical coordinate data acquisition device provided by the present application will be described in detail below with reference to the accompanying drawings.
[0044] See also Figure 1 , Figure 1 Schematic diagram of the structure of the first embodiment of the optical coordinate data acquisition device provided in the embodiment of the present application. Figure 1 As shown, in some embodiments, the optical coordinate data acquisition device 1 includes a main body T, a tip point S, at least three optical marker components 10, and a trigger component 20. The tip point S is used to be placed at the target position, all optical marker components 10 are fixedly mounted on the main body T, and the trigger component 20 is used to trigger the electronic device to calculate the optical coordinates of the target position in the camera coordinate system.
[0045] like Figure 1 As shown, in some embodiments, the initial position of the trigger component 20 and the installation positions of all optical marker components 10 conform to a preset positional relationship. Specifically, the installation position of each optical marker component 10 is the preset installation position corresponding to the optical marker component 10, and the initial position of the trigger component 20 is the preset installation position corresponding to the trigger component 20. In this way, in the image, the relative positional relationship between the initial position of the trigger component 20 and the installation positions of all optical marker components 10 is determined, making it easy to calculate the optical coordinates of the target position based on this determined relative positional relationship.
[0046] It is understandable that Figure 1 This is only an example of one embodiment, and the initial position of the trigger component 20 and the installation positions of all optical marking components 10 are not necessarily Figure 1 The initial position of the trigger component 20 and the installation positions of all optical marking components 10 can conform to any relative position relationship. The initial position of the trigger component 20 is not necessarily as shown. Figure 1 As shown near the tip point S, the initial position of the trigger member 20 can be anywhere on the body T.
[0047] In some embodiments, the optical marker component 10 is a reflective marker, each of which has a reflective center. The reflective marker is used to reflect light of a specific wavelength (such as laser or infrared light), so it appears as a clearly identifiable feature point in the image, making it easier for electronic devices to calculate the position coordinates of the optical marker component 10 based on the image.
[0048] In some embodiments, the trigger component 20 is also a reflective marker.
[0049] like Figure 1 As shown, in some embodiments, the trigger component 20 is fixedly mounted on the main body T.
[0050] See also Figure 2A and Figure 2B , Figure 2A This is a schematic diagram of a usage scenario of the first embodiment of the optical coordinate data acquisition device provided in an embodiment of the present application when calculation of the electronic device is not triggered. Figure 2B This is a schematic diagram of a usage scenario when triggering electronic device calculation in the first embodiment of the optical coordinate data acquisition device provided in the embodiment of the present application. Figure 2A As shown, when the electronic device is not triggered to calculate, the trigger component 20 is not blocked. Figure 2B As shown, when triggering the electronic device to calculate, trigger component 20 is obscured. In this case, no feature points representing trigger component 20 exist in the image. The electronic device can determine based on the image that trigger component 20 is obscured and then trigger the calculation process. In this way, the user can trigger the electronic device to calculate the optical coordinates of the target position without the aid of an external control device, thereby improving the ease of use of the optical coordinate data acquisition device 1.
[0051] In some embodiments, the optical coordinate data acquisition device 1 further includes a movable component configured to drive the trigger component 20 along a predetermined motion trajectory. If the trigger component 20 is not in its initial position after movement, the electronic device can determine, based on the image, that the trigger component 20 is in the trigger position and then trigger the calculation process. This allows the user to trigger the electronic device to calculate the optical coordinates of the target location without the aid of an external control device, thereby improving the ease of use of the optical coordinate data acquisition device 1.
[0052] See also Figure 3 , Figure 3 This is a structural diagram of the second embodiment of the optical coordinate data acquisition device provided in the embodiment of the present application when the electronic device calculation is not triggered. Figure 3As shown, in some embodiments, the movable component is a sliding mechanism 30. The sliding mechanism 30 includes a slide rail 31 provided on the main body T and a slider 32 slidably mounted on the slide rail 31. The slider 32 is fixedly connected to the trigger component 20 and is used to drive the trigger component 20 to move along the slide rail 31. At this time, the trigger component 20 is in the initial position.
[0053] like Figure 3 As shown, in some embodiments, the slider 32 is fixedly connected to the trigger component 20 via a fixing rod.
[0054] Optionally, the fixing rod may be in any shape such as a straight line or a curved line.
[0055] In other embodiments, the trigger component 20 is directly fixedly mounted on the slider 32 .
[0056] Optionally, the slide rail 31 may be in any shape, such as a straight line or a curve. The user may push the slider 32 to move the trigger component 20 along a preset motion track.
[0057] like Figure 3 As shown, in some embodiments, during use, the user can push the slider 32 in the direction indicated by the arrow R1 to move the trigger component 20 along the slide rail 31 .
[0058] See also Figure 4 , Figure 4 This is a schematic diagram of the structure of the triggering electronic device calculation of the second embodiment of the optical coordinate data acquisition device provided in the embodiment of the present application. Figure 4 As shown, Figure 4 The middle triggering component 20 is located at the triggering position after moving along the slide rail 31 .
[0059] In other embodiments, the trigger component 20 is directly slidably mounted on the slide rail 31 . The user can directly push the trigger component 20 to move along the slide rail 31 .
[0060] like Figure 3 As shown, in some embodiments, the sliding mechanism 30 includes a first reset mechanism 33, wherein a first end of the first reset mechanism 33 is fixedly connected to one end of the slide rail 31, and a second end of the first reset mechanism 33 is connected to one end of the slider 32. The first reset mechanism 33 is used to position the slider 32 in a first initial position when no external force is applied. In this manner, when the user does not apply external force to the slider 32, the slider 32 can automatically return to the first initial position, and the trigger component 20 will also automatically return to the initial position, allowing the user to operate the slider 32 again to trigger the electronic device to perform calculations, thereby further improving the ease of use of the optical coordinate data acquisition device 1.
[0061] like Figure 3As shown, in some embodiments, the first reset mechanism 33 is a first elastic component, a first end of the first elastic component is fixedly connected to one end of the slide rail 31 , and a second end of the first elastic component is connected to one end of the slider 32 .
[0062] Optionally, when the user applies external force to the slider 32 to cause the trigger component 20 to leave the initial position, the first elastic component will be stretched or compressed. When the user does not apply external force to the slider 32, the first elastic component will drive the slider 32 to automatically return to the first initial position during the process of restoring its original shape, and the trigger component 20 will also automatically return to its initial position.
[0063] For example, Figure 3 and Figure 4 As shown, when the slider 32 moves in the direction indicated by the arrow R1, the first elastic component will be compressed. When the user does not apply external force to the slider 32, the first elastic component will drive the slider 32 to automatically return to the first initial position in the opposite direction of the arrow R1 during the process of restoring its original shape, and the trigger component 20 will also automatically return to the initial position.
[0064] Optionally, the first elastic component may be a spring or elastic rubber.
[0065] In some embodiments, the first reset mechanism 33 includes a first magnetic component and a second magnetic component. The first magnetic component is fixedly mounted on one end of the slide rail 31 , and the second magnetic component is fixedly mounted on one end of the slider 32 .
[0066] In some embodiments, the adjacent magnetic poles of the first and second magnetic components have different magnetic properties, and the direction of the line from the first magnetic component to the second magnetic component is opposite to the direction of movement of the slider 32. When the user applies an external force to the slider 32 to cause the trigger component 20 to move away from the initial position, the first and second magnetic components continue to attract each other. When the user does not apply an external force to the slider 32, the mutual attraction between the first and second magnetic components drives the second magnetic component to move, and the slider 32 is then automatically restored to the first initial position by the second magnetic component, and the trigger component 20 is also automatically restored to the initial position.
[0067] In other embodiments, the adjacent magnetic poles of the first and second magnetic components have the same magnetic properties, and the direction of the line from the first magnetic component to the second magnetic component is the same as the direction of movement of the slider 32. When the user applies an external force to the slider 32 to cause the trigger component 20 to move away from the initial position, the first and second magnetic components continue to repel each other. During the movement of the trigger component 20, the distance between the first and second magnetic components gradually decreases, and the repulsive force gradually increases. When the user does not apply an external force to the slider 32, the mutual repulsive force between the first and second magnetic components drives the second magnetic component to move, and the slider 32 is then automatically restored to the first initial position by the second magnetic component, and the trigger component 20 also automatically returns to its initial position.
[0068] See also Figure 5 , Figure 5 This is a structural diagram of the third embodiment of the optical coordinate data acquisition device provided in the embodiment of the present application when the electronic device calculation is not triggered. Figure 5 As shown, in some embodiments, the movable component is a rotating mechanism 40. The rotating mechanism 40 includes a fixed portion 41 disposed on the main body T and a rotating portion 42 rotatably connected to the fixed portion 41. The rotating portion 42 is fixedly connected to the trigger component 20 and is used to drive the trigger component 20 to rotate along a predetermined rotation trajectory. At this time, the trigger component 20 is in the initial position.
[0069] like Figure 5 As shown, the fixed portion 41 optionally serves as a fulcrum, the first end of the rotating portion 42 is fixedly connected to the trigger component 20, and the second end of the rotating portion 42 is used for the user to apply an external force. During use, the user can push the rotating portion 42 in the direction indicated by arrow R2, causing the trigger component 20 to rotate tangentially in the direction indicated by arrow R3, with the fixed portion 41 as the fulcrum.
[0070] See also Figure 6 , Figure 6 This is a schematic diagram of the structure of the triggering electronic device calculation of the third embodiment of the optical coordinate data acquisition device provided in the embodiment of the present application. Figure 6 As shown, Figure 6 The middle trigger component 20 is located at the trigger position after rotation.
[0071] In some embodiments, the rotation mechanism 40 includes a second reset mechanism 43. The first end of the second reset mechanism 43 is fixedly mounted on the main body T near one end of the rotation portion 42, and the second end of the second reset mechanism 43 is connected to one end of the rotation portion 42. The second reset mechanism 43 is used to position the rotation portion 42 in the second initial position when no external force is applied. In this way, when the user does not apply external force to the rotation portion 42, the rotation portion 42 can automatically return to the second initial position, and the trigger component 20 will also automatically return to the initial position, allowing the user to operate the rotation portion 42 again to trigger the electronic device to calculate, thereby further improving the ease of use of the optical coordinate data acquisition device 1.
[0072] like Figure 5 As shown, in some embodiments, the second reset mechanism 43 is a second elastic component, which is fixedly installed on the main body T near one end of the rotating part 42 , and the second end of the second elastic component is connected to one end of the rotating part 42 .
[0073] Optionally, when the user applies external force to the rotating part 42 to cause the trigger component 20 to leave the initial position, the second elastic component will be stretched or compressed. When the user does not apply external force to the rotating part 42, the second elastic component will drive the rotating part 42 to automatically return to the first initial position in the process of restoring its original shape, and the trigger component 20 will also automatically return to the initial position.
[0074] For example, Figure 5 and Figure 6 As shown, when the rotating part 42 is pushed in the direction indicated by the arrow R2 and the elastic component is rotated in the direction indicated by the arrow R3 with the fixed part 41 as the fulcrum, the second elastic component will be compressed. When the user does not apply external force to the rotating part 42, the second elastic component will drive the rotating part 42 to automatically return to the first initial position in the opposite direction of the direction indicated by the arrow R2 during the process of restoring its original shape, and the trigger component 20 will also automatically return to the initial position.
[0075] Optionally, the second elastic component may be a spring or elastic rubber.
[0076] In some embodiments, the second reset mechanism 43 includes a third magnetic component and a fourth magnetic component. The third magnetic component is fixedly installed on the main body T near one end of the rotating portion 42 , and the fourth magnetic component is fixedly installed on one end of the rotating portion 42 .
[0077] In some embodiments, the adjacent magnetic poles of the third and fourth magnetic components have the same magnetic properties. The third magnetic component is fixedly mounted on the main body T near the first end of the rotating portion 42 fixedly connected to the trigger component 20, and the fourth magnetic component is fixedly mounted on the first end of the rotating portion 42. When a user applies an external force to the rotating portion 42 to cause the trigger component 20 to move from the initial position, the third and fourth magnetic components remain attracted to each other. When the user does not apply external force to the rotating portion 42, the mutual attraction between the third and fourth magnetic components drives the fourth magnetic component to move, and the rotating portion 42 is then automatically restored to the second initial position by the fourth magnetic component, and the trigger component 20 is also automatically restored to its initial position.
[0078] In some embodiments, the adjacent magnetic poles of the third and fourth magnetic components have different magnetic properties. The third magnetic component is fixedly mounted on the main body T near the second end of the rotating portion 42 that is not fixedly connected to the trigger component 20, and the fourth magnetic component is fixedly mounted on the second end of the rotating portion 42. When a user applies an external force to the rotating portion 42 to cause the trigger component 20 to move from its initial position, the third and fourth magnetic components continuously repel each other. During the movement of the trigger component 20, the distance between the third and fourth magnetic components gradually decreases, and the repulsive force gradually increases. When the user does not apply an external force to the rotating portion 42, the mutual repulsive force between the third and fourth magnetic components drives the fourth magnetic component to move, and the rotating portion 42 is then automatically restored to its second initial position by the fourth magnetic component, and the trigger component 20 also automatically returns to its initial position.
[0079] In summary, the optical coordinate data acquisition device 1 provided in the embodiment of the present application has the following advantages:
[0080] 1. The trigger component 20 is used to trigger the electronic device to calculate the optical coordinates of the target position in the camera coordinate system, which enables the user to trigger the electronic device to calculate the optical coordinates of the target position without the help of an external control device, thereby improving the convenience of using the optical coordinate data acquisition device 1.
[0081] 2. By including a first reset mechanism 33 in the sliding mechanism 30, when the user does not apply external force to the slider 32, the slider 32 can automatically return to the first initial position, and the trigger component 20 will also automatically return to the initial position, so that the user can operate the slider 32 again to trigger the electronic device to calculate, thereby further improving the ease of use of the optical coordinate data acquisition device 1.
[0082] 3. By including a second reset mechanism 43 in the rotating mechanism 40, when the user does not apply external force to the rotating part 42, the rotating part 42 can automatically return to the second initial position, and the trigger component 20 will also automatically return to the initial position, so that the user can operate the rotating part 42 again to trigger the electronic device to calculate, thereby further improving the ease of use of the optical coordinate data acquisition device 1.

The tip point S is used to be placed at a target position, and all optical marker components 10 are fixedly mounted on the main body T. The trigger component 20 is used to trigger an electronic device to calculate the optical coordinates of the target position in a camera coordinate system. The present application uses the trigger component 20 to trigger the electronic device to calculate the optical coordinates of the target position in the camera coordinate system, which enables the user to trigger the electronic device to calculate the optical coordinates of the target position without the aid of an external control device, thereby improving the ease of use of the optical coordinate data acquisition device 1.
