[0030] The medical handheld mobile terminal provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0031] Please refer to Figures 1 to 10 As shown in the embodiment of this application, a medical handheld mobile terminal is provided, which includes a control element 100 and at least two camera modules 200.

[0032] Specifically, at least two camera modules 200 include a first camera module 200a and a second camera module 200b. The first camera module 200a and the second camera module 200b are arranged at intervals and are both communicatively connected to the control element 100. The first camera module 200a is used to capture a first image of the object under test, and the second camera module 200b is used to capture a second image of the object under test. The first camera module 200a and the second camera module 200b are, for example, cameras.

[0033] The control element 100 is used to acquire the distance between the object under test and the medical handheld mobile terminal and / or the size of the object under test based on the first image and the second image. That is, the control element 100 may acquire only the distance between the object under test and the medical handheld mobile terminal or the size of the object under test based on the first image and the second image, or it may acquire both the distance between the object under test and the medical handheld mobile terminal or the size of the object under test simultaneously.

[0034] In this embodiment, the first camera module 200a of the medical handheld mobile terminal is used to capture a first image of the object under test, and the second camera module 200b is used to capture a second image of the object under test. The control element 100 is used to obtain the distance between the object under test and the medical handheld mobile terminal and / or the size of the object under test based on the first and second images. With this configuration, through the cooperation of the first camera module 200a, the second camera module 200b, and the control element 100, the user can obtain the distance between the object under test and the medical handheld mobile terminal and / or the size of the object under test. Therefore, compared with traditional medical handheld mobile terminals, the medical handheld mobile terminal provided in this embodiment additionally has the function of measuring the distance between the object under test and the medical handheld mobile terminal and / or the size of the object under test, making its functions more diverse and better meeting the user's needs.

[0035] Optionally, the line connecting the optical axes of the first camera module 200a and the second camera module 200b is defined as the baseline. The line connecting the optical axes of the first camera module 200a and the second camera module 200b refers to the vertical line connecting the optical axes of the first camera module 200a and the second camera module 200b. The distance between the object under test and the baseline is the distance between the object under test and the medical handheld mobile terminal mentioned above. The image plane of the first camera module 200a and the image plane of the second camera module 200b are the same plane. For ease of description, this plane is defined as the first plane 90°.

[0036] The measurement principle of the medical handheld mobile terminal provided in this application embodiment is as follows:

[0037] Based on the parallax principle, the first camera module 200a and the second camera module 200b acquire the first image and the second image of the object under test from different positions, respectively. By calculating the positional deviation between corresponding points in the first image and the second image, the three-dimensional geometric information of the object under test is obtained.

[0038] More specifically, the principle for measuring the distance between the object being tested and the medical handheld mobile terminal provided in the embodiments of this application is as follows:

[0039] refer to Figure 2 As shown, the first camera module 200a and the second camera module 200b are cameras of the same specifications, and Figure 2 In the diagram, O1 represents the first camera module 200a, O2 represents the second camera module 200b, T represents the distance between the first camera module 200a and the second camera module 200b, f represents the focal length of the first camera module 200a or the second camera module 200b, P represents the object under test, X1 represents the pixel of the object under test on the image plane of the first camera module 200a, X2 represents the pixel of the object under test on the image plane of the second camera module 200b, d represents the distance between X1 and X2, which can be obtained through an algorithm, and Z represents the distance from the object under test to the baseline, that is, the distance between the object under test and the medical handheld mobile terminal.

[0040] In actual use, the control element 100 can obtain the first image captured by the first camera module 200a and the second image captured by the second camera module 200b. Figure 2 The image shown. According to... Figure 2 Based on the properties of similar triangles, the following equation 1 can be derived from the image shown:

[0041] Formula 1,

[0042] Furthermore, we can derive the following equation 2:

[0043] Equation 2,

[0044] The distance between the object being measured and the medical handheld mobile terminal can be calculated using Equation 2 above.

[0045] The principle of measuring the size of the object being measured is as follows:

[0046] refer to Figure 3 As shown, the first camera module 200a and the second camera module 200b are cameras of the same specifications, and Figure 3In the diagram, O1 represents the first camera module 200a, O2 represents the second camera module 200b, T represents the distance between the first camera module 200a and the second camera module 200b, f represents the focal length of the first camera module 200a or the second camera module 200b, P′ and P″ represent two points on the object being measured, X1′ represents the pixel point of P′ on the image plane of the first camera module 200a, X2′ represents the pixel point of P′ on the image plane of the second camera module 200b, and X1″ represents the pixel point of P′ on the image plane of the second camera module 200b. "X2" represents the pixel point P" on the image plane of the first camera module 200a, "X2" represents the pixel point P" on the image plane of the second camera module 200b, "Z'" represents the distance of P' to the baseline mentioned above, "Z" represents the distance of P" to the baseline mentioned above, "α" is the field of view angle of P' relative to the first camera module 200a, "β" is the field of view angle of P" relative to the first camera module 200a, and "θ" is the parallax angle of P' and P" relative to the first camera module 200a. α and "β" can be obtained by an algorithm. Furthermore, α, "β", and "θ" satisfy the following relationship:

[0047] θ = β - α.

[0048] In actual use, the control element 100 can obtain the first image captured by the first camera module 200a and the second image captured by the second camera module 200b. Figure 3 The image shown. According to... Figure 3 The graph shown, combined with trigonometric functions, yields equations 3 through 6:

[0049] Formula 3,

[0050] Equation 4,

[0051] Equation 5, |MP″|=|O1P″|×sinθ;

[0052] Equation 6, |MP′|=|O1P″|×cosθ-|O1P′|.

[0053] Further, refer to Figure 3 As shown, in triangle P′MP″, according to the Pythagorean theorem, the distance S between points P′ and P″ on the object to be measured satisfies the following equation:

[0054] Equation 7,

[0055] Furthermore, combining equations 5 and 6 above, we can derive equation 8:

[0056] Formula 8,

[0057] Furthermore, combining equations 3 and 4 above, we can derive equation 9:

[0058] Formula 9,

[0059] In addition, in equations 3 to 9 above, |O1P′| represents the distance from O1 to point P′, |O1P″| represents the distance from O1 to point P″, |MP′| represents the distance from M to point P′, and |MP″| represents the distance from M to point P″.

[0060] In practical use, the dimensions of the object to be tested can be measured in multiple different directions. For example, a patient's sore can be measured. Specifically, medical personnel can periodically measure the size of the sore using the medical handheld mobile terminal provided in this embodiment. Based on changes in the size of the patient's sore, medical personnel can determine the healing speed of the sore.

[0061] The medical handheld mobile terminal provided in this application will be described in detail below with reference to a specific embodiment:

[0062] In this embodiment, reference Figure 4 As shown, the field of view of both the first camera module 200a and the second camera module 200b is 86 degrees. In order to reduce the influence of image distortion on the measurement results, the angle between the line connecting the object under test and the first camera module 200a and the optical axis of the first camera module 200a is, for example, no greater than 5 degrees. At the same time, the angle between the line connecting the object under test and the second camera module 200b and the optical axis of the second camera module 200b is no greater than 5 degrees, so as to ensure that the proportions of the first image and the second image are closer to the actual object. Figure 4 In the diagram, O1 represents the first camera module 200a, O2 represents the second camera module 200b, T represents the distance between the first camera module 200a and the second camera module 200b, arrow a represents the optical axis direction of the first camera module 200a, arrow b represents the optical axis direction of the second camera module 200b, and Z represents the distance between the object under test and the baselines of the first and second camera modules 200a. The angle between the line connecting the object under test and the first camera module 200a and the optical axis direction of the first camera module 200a is, for example, 5 degrees. Similarly, the angle between the line connecting the object under test and the second camera module 200b and the optical axis direction of the second camera module 200b is also 5 degrees.

[0063] In this embodiment, the control element 100 obtains, for example, based on the first image and the second image. Figure 4 The image shown is based on Figure 4 The image shown, combined with trigonometric functions, yields the following equation 10:

[0064] Formula 10,

[0065] Based on equation 10 above, we can further derive equation 11 below:

[0066] Formula 11,

[0067] When medical personnel use a medical handheld mobile terminal to take pictures of the object to be tested, such as a patient's wound, the value of Z is usually between 15cm and 25cm. Therefore, according to the above formula 11, the value of T is between 26mm and 44mm. More specifically, T is, for example, 32mm.

[0068] In another embodiment, reference Figure 1 As shown, the medical handheld mobile terminal also includes a mounting base 300. The mounting base 300 has a first mounting groove 310, which corresponds one-to-one with a camera module 200. At least a portion of each camera module 200 is located in the corresponding first mounting groove 310. The arrangement direction of the first camera module 200a and the second camera module 200b intersects with, for example, the depth direction of the first mounting groove 310, for example, perpendicular to it. The depth direction of the first mounting groove 310 is, for example, [missing information]. Figure 6 The direction indicated by the middle arrow line W. The first camera module 200a and the second camera module 200b are both matched with the corresponding first mounting slot 310 in the upper limit of the arrangement direction of the first camera module 200a and the second camera module 200b.

[0069] In this embodiment, the installation position of the camera module 200 can be located more conveniently and quickly with the help of the first mounting slot 310, thereby reducing the installation difficulty of the camera module 200 and improving the installation accuracy of the camera module 200.

[0070] Furthermore, in this embodiment, both the first camera module 200a and the second camera module 200b are fitted with the corresponding first mounting groove 310 in an upper limit engagement in the arrangement direction of the first camera module 200a and the second camera module 200b. This restricts the movement of both the first camera module 200a and the second camera module 200b in their respective arrangement directions, thereby improving the stability of the first camera module 200a and the second camera module 200b. With this configuration, the distance between the first camera module 200a and the second camera module 200b is less likely to change under external impact. The distance between the first camera module 200a and the second camera module 200b, i.e., T mentioned earlier, directly relates to the measurement accuracy of the distance between the object being measured and the medical handheld mobile terminal, as well as the measurement accuracy of the object's dimensions. Therefore, the solution in this embodiment can improve the measurement accuracy of the distance between the object being measured and the medical handheld mobile terminal, as well as the measurement accuracy of the object's dimensions.

[0071] In other alternative embodiments, the mounting base 300 may not have the first mounting groove 310. In this case, the camera module 200 may be directly mounted on the surface of the mounting base 300.

[0072] In a further embodiment, both the first camera module 200a and the second camera module 200b are positioned to engage with the bottom of the corresponding first mounting groove 310 at the upper limit of the depth direction of the first mounting groove 310. This configuration restricts the movement of the first camera module 200a and the second camera module 200b in both their arrangement direction and the depth direction of the first mounting groove 310, thereby improving the stability of the first camera module 200a and the second camera module 200b and increasing the accuracy of measuring the distance between the object being measured and the medical handheld mobile terminal, as well as the dimensions of the object being measured.

[0073] In other alternative embodiments, the first camera module 200a and the second camera module 200b may not have a limiting fit relationship with the bottom of the corresponding first mounting groove 310 in the depth direction of the first mounting groove 310.

[0074] In a further embodiment, both the first camera module 200a and the second camera module 200b are engaged with the corresponding first mounting groove 310 in a first direction. This first direction intersects with both the arrangement direction of the first camera module 200a and the second camera module 200b and the depth direction of the first mounting groove 310. Specifically, the first direction is, for example, perpendicular to both the arrangement direction of the first camera module 200a and the second camera module 200b and the depth direction of the first mounting groove 310.

[0075] In this embodiment, the movement of the first camera module 200a and the second camera module 200b in both their arrangement direction and the first direction is simultaneously restricted. This also makes the stability of the first camera module 200a and the second camera module 200b better, and makes the measurement accuracy of the distance between the object under test and the medical handheld mobile terminal and the size of the object under test higher.

[0076] In other alternative embodiments, the first camera module 200a and the second camera module 200b may not have a limiting fit relationship with the corresponding first mounting groove 310 in the first direction.

[0077] In one optional embodiment, the first camera module 200a and the second camera module 200b are both fitted with the corresponding first mounting groove 310 at the upper limit of the arrangement direction of the first camera module 200a and the second camera module 200b. The bottom of the first camera module 200a and the second camera module 200b are both fitted with the upper limit of the depth direction of the corresponding first mounting groove 310. At the same time, the first camera module 200a and the second camera module 200b are both fitted with the corresponding first mounting groove 310 at the upper limit of the first direction, so as to further improve the stability of the first camera module 200a and the second camera module 200b, and further improve the measurement accuracy of the distance between the object under test and the medical handheld mobile terminal and the size of the object under test.

[0078] In another embodiment, reference Figures 5 to 7 As shown, a portion of the sidewall 311 of the first mounting groove 310 is recessed along a direction away from the center line of the first mounting groove 310, forming at least two recessed portions 320. Each recessed portion 320 is spaced circumferentially along the first mounting groove 310, and each recessed portion 320 contains a first adhesive member. The camera module 200, such as the first camera module 200a or the second camera module 200b mentioned above, is bonded to the mounting base 300 via the first adhesive member. With this configuration, the camera module 200 can be installed through a simple bonding operation, thus reducing the difficulty of installing the camera module 200. Furthermore, in this embodiment, the number of recessed portions 320 is at least two, and each recessed portion 320 contains a first adhesive member. This ensures that the camera module 200 and the mounting base 300 are connected by at least two first adhesive members, resulting in a more reliable connection between the two.

[0079] Optionally, for example, adhesive is filled into the recess 320, and after the adhesive cures, a first adhesive component is formed, and reference is made to... Figure 5 As shown, the width J of the first adhesive component is, for example, 1 mm.

[0080] Optionally, the shapes of the recesses 320 may differ, for example. Referring to Figure 5, the recess 320 located at the corner of the first mounting groove 310 is approximately "L"-shaped, while the recesses 320 located at other positions are approximately "I"-shaped. Of course, in other embodiments, the shapes of the recesses 320 may also be the same. In this embodiment, the shape and size of the recesses 320 are not limited, and can be designed according to actual needs.

[0081] Furthermore, a second adhesive member can be provided between the camera module 200 and the bottom of the first mounting groove 310, so that the camera module 200 is simultaneously bonded to the mounting base 300 by both the first and second adhesive members, thereby making the connection between the camera module 200 and the mounting base 300 more reliable. Of course, in other embodiments, the camera module 200 can also be bonded to the mounting base 300 solely by the second adhesive member.

[0082] In other alternative embodiments, the camera module 200 may also be connected to the mounting base 300 by means of welding or screw connection.

[0083] In one optional embodiment, in the depth direction of the first mounting groove 310, the ratio of the thickness of the portion of the camera module 200 located in the first mounting groove 310 to the total thickness of the camera module 200 is greater than two-thirds. With this configuration, a larger portion of the camera module 200 is located in the first mounting groove 310, resulting in a larger mating area between the first mounting groove 310 and the camera module 200, thereby improving the stability of the camera module 200.

[0084] Optionally, the thickness of the portion of the camera module 200 located in the first mounting slot 310 is, for example, 0.72 mm.

[0085] In one alternative embodiment, the ratio of the thickness of the portion of the camera module 200 located in the first mounting groove 310 to the total thickness of the camera module 200 in the depth direction of the first mounting groove 310 may be less than or equal to two-thirds.

[0086] In another embodiment, reference Figure 5 As shown, a preset installation gap K is provided between the side wall 311 of the first mounting groove 310 and the corresponding camera module 200. Optionally, the preset installation gap is, for example, greater than 0 mm and less than or equal to 0.1 mm, more specifically, for example, 0.05 mm.

[0087] In this embodiment, the existence of the preset installation gap provides installation leeway for the camera module 200, allowing it to be smoothly installed into the first mounting slot 310. Of course, in other optional embodiments, there may be no preset installation gap between the side wall 311 of the first mounting slot 310 and the corresponding camera module 200; in this case, the side wall 311 of the first mounting slot 310 may, for example, be in contact with the camera module 200.

[0088] In another embodiment, reference Figure 7As shown, the side wall 311 of the first mounting slot 310 has an opening 330. The medical handheld mobile terminal also includes an electrical connector 400. One end of the electrical connector 400 is electrically connected to the control element 100, and the other end passes through the opening 330 and is electrically connected to the camera module 200. With this arrangement, at least a portion of the electrical connector 400 is located in the opening 330, which makes the medical handheld terminal more compact. In addition, the opening 330 allows for convenient and quick installation of the electrical connector 400, thereby reducing the installation difficulty of the electrical connector 400.

[0089] Optionally, the electrical connector 400 may be, for example, a flexible circuit board, and the control element 100 may include, for example, a motherboard, with the electrical connector 400 electrically connected to the motherboard.

[0090] In other alternative embodiments, the sidewall 311 of the first mounting groove 310 may not have an opening 330. In this case, the first mounting groove 310 may surround the camera module 200 circumferentially, for example.

[0091] In another embodiment, reference Figure 9 As shown, the medical handheld mobile terminal also includes a supplementary lighting element 500, which is used to provide supplementary lighting for the first camera module 200a and the second camera module 200b.

[0092] In this embodiment, in a dim environment, the supplementary lighting element 500 can provide supplementary lighting for the first camera module 200a and the second camera module 200b, thereby improving the brightness of the first image captured by the first camera module 200a and the second image captured by the second camera module 200b in a dim environment, and thus improving the shooting quality of the first image and the second image.

[0093] In other alternative embodiments, the medical handheld mobile terminal may also exclude the supplementary lighting element 500.

[0094] In a further embodiment, reference is made to... Figure 9 and Figure 10 As shown, the optical axis of the supplementary lighting element 500, the optical axis of the first camera module 200a, and the optical axis of the second camera module 200b are parallel, and the supplementary lighting element 500 is located on the perpendicular bisector of the line connecting the optical axes of the first camera module 200a and the second camera module 200b. With this configuration, the supplementary lighting element 500 provides the same illumination to both the first and second camera modules 200a and 200b, resulting in higher consistency in brightness between the first and second images, thereby reducing the impact of brightness inconsistencies between the first and second images on the detection results.

[0095] Specifically, Figure 10The "V" in the diagram represents the distance between the perpendicular bisector of the line connecting the first camera module 200a and the second camera module 200b, and the first camera module 200a. Figure 10 In the diagram, H represents the distance between the perpendicular bisector of the line connecting the first camera module 200a and the second camera module 200b and the second camera module 200b. V and H are both, for example, 16mm.

[0096] In other alternative embodiments, the supplementary lighting element 500 may not be located on the perpendicular bisector of the line connecting the first camera module 200a and the second camera module 200b. In this case, the supplementary lighting effect of the supplementary lighting element 500 on the first camera module 200a and the second camera module 200b will be different.

[0097] In a further embodiment, the medical handheld mobile terminal also includes a focusing element 600, located on the light-emitting side of the supplementary light element 500, and used to converge the light emitted by the supplementary light element 500. With this configuration, the light emitted by the supplementary light element 500 converges towards the optical axis closer to the supplementary light element 500, which helps to increase the amount of light directed towards the first camera module 200a and the second camera module 200b, thereby helping to improve the brightness of the object being measured.

[0098] Optionally, the focusing element 600 may be, for example, a focusing lens, and more specifically, for example, a Fresnel lens.

[0099] In other alternative embodiments, the medical handheld mobile terminal may also exclude the focusing element 600.

[0100] In another embodiment, the medical handheld mobile terminal also includes a camera element 700, the pixel values ​​of which differ from those of the camera module 200, and the camera element 700 is communicatively connected to the control element 100. With this configuration, the camera element 700 and the camera module 200 can respectively meet different shooting requirements, thereby making the medical handheld mobile terminal more versatile. It should be noted that pixel value refers to the number of pixels per unit area.

[0101] Optionally, the total number of pixels of the image sensor 700 may be greater than the total number of pixels of the image sensor module 200. This results in higher image resolution from the image sensor 700 compared to the image sensor module 200, thus meeting the user's requirement for high-resolution images. More specifically, the total number of pixels of the image sensor 700 may be, for example, 50 million, and the total number of pixels of the image sensor module 200 may be, for example, 8 million. Furthermore, the image sensor 700 may also be, for example, a camera.

[0102] Optionally, the mounting base 300 may be provided with a second mounting slot, and the camera element 700 may be located in the second mounting slot. The second mounting slot allows for easier and faster installation of the camera element 700, thereby reducing the difficulty of installing the camera element 700.

[0103] In other alternative embodiments, the medical handheld mobile terminal may also exclude the camera element 700.

[0104] In a further embodiment, reference is made to... Figure 1 As shown, the medical handheld mobile terminal also includes a mounting base 300. Camera elements 700, a first camera module 200a, and a second camera module 200b are all located on the same surface along the thickness direction of the mounting base 300. The first camera module 200a and the second camera module 200b are arranged alternately along a second direction. Camera elements 700 and either the first camera module 200a or the second camera module 200b are arranged alternately along a third direction. The second direction, the third direction, and the thickness direction of the mounting base 300 intersect each other. The second direction is the arrangement direction of the first camera module 200a and the second camera module 200b mentioned above. Figure 1 The direction indicated by arrow B in the diagram is the second direction. Figure 1 The direction indicated by arrow A is the third direction, and the thickness direction of the mounting base 300 is, for example, the same as the depth direction of the first mounting groove 310 mentioned above. In this layout, the arrangement of the camera element 700, the first camera module 200a, and the second camera module 200b is more reasonable, which helps to reduce the size of the medical handheld mobile terminal.

[0105] Specifically, refer to Figure 1 As shown, the distance T between the first camera module 200a and the second camera module 200b in the second direction is, for example, 32mm.

[0106] In other alternative embodiments, the first camera module 200a, the second camera module 200b, and the camera element 700 may also be arranged at intervals along the second direction.

[0107] As one specific implementation method, refer to Figure 8As shown, the medical handheld mobile terminal also includes components such as a display screen 810, a reinforcing plate 820, an antenna bracket 850, a back cover 830, and a transparent cover 840. The display screen 810 is adhered to the back cover 830, and the display screen 810 displays images and provides an operating interface for the user. The reinforcing plate 820, control element 100, mounting base 300, and antenna bracket 850 are all located between the display screen 810 and the back cover 830, and are arranged sequentially along the thickness direction of the display screen 810. The reinforcing plate 820, located between the control element 100 and the display screen 810, improves the medical handheld mobile terminal's resistance to external impacts. The antenna bracket 850 is used for information interaction between the medical handheld mobile terminal and other electronic devices. The back cover 830 is the medical handheld mobile terminal itself. The internal components are mounted on a foundation. Components such as the reinforcing plate 820, antenna bracket 850, mounting base 300, and control element 100 are all threaded onto the rear housing 830. The rear housing 830 has a first opening, a second opening, and a third opening. The first opening corresponds to the first camera module 200a, the second opening corresponds to the second camera module 200b, and the third opening corresponds to the camera element 700. A transparent cover plate 840 covers the first, second, and third openings to prevent damage to the first camera module 200a, the second camera module 200b, and the camera element 700 from external impacts. Optionally, the reinforcing plate 820 may be, for example, an alloy plate, and the transparent cover plate 840 may be made of, for example, transparent glass.
