Description

Technical Field

[0001] This utility model relates to the field of three-dimensional spatial indication and ranging technology, and in particular to a mobile phone holder with a two-axis electric gimbal. Background Technology

[0002] Spatial indication and spatial ranging, relying on depth measurement technology and devices, are widely used in intelligent spatial indication and spatial ranging scenarios such as classroom teaching, lectures, sand table, architecture, field search, and hospitals.

[0003] Existing methods for remote indication or distance measurement based on captured images all require separate configurations of a camera device, an indication mechanism, a distance measuring mechanism, and a pan-tilt unit. The indication and distance measuring mechanisms are mounted on the pan-tilt unit, and the pan-tilt unit is rotated based on the image captured by the camera device to complete the remote spatial indication or distance measurement. In other words, existing remote indication mechanisms require separate camera devices and pan-tilt units for users to indicate the distance from a point in a captured image to an actual spatial point, resulting in high costs and inconvenience for users to perform remote spatial indication and distance measurement based on images.

[0004] With the development of mobile technology, smartphones have become increasingly powerful AR / VR devices, possessing high-precision depth measurement capabilities, such as LiDAR depth measurement and binocular depth measurement, with a ranging range of over 5 meters and millimeter-level accuracy. This has made portable spatial indication and spatial measurement possible.

[0005] Currently, there is no research on using smartphones to replace existing camera mechanisms in portable spatial indication and measurement to solve the problems of high cost and inconvenience for users to perform spatial indication and spatial distance measurement through images. Utility Model Content

[0006] Therefore, the purpose of this utility model is to provide a mobile phone holder with a two-axis electric gimbal, which makes full use of the user's existing smartphone to quickly indicate the target area.

[0007] A mobile phone holder with a two-axis motorized gimbal, comprising:

[0008] A base;

[0009] A mobile phone loading mechanism, which is fixedly connected to the base, has the function of positioning the zero point of the mobile phone camera coordinate system;

[0010] A gimbal is mounted on a base, and the mounting position is located at a fixed point in the camera coordinate system determined by the parameters of the external mobile phone camera mechanism mounted on the mobile phone loading mechanism.

[0011] A load is fixedly mounted on the gimbal and rotates synchronously with the gimbal.

[0012] A controller, comprising a communication module and a control module, controls the rotation of the pan-tilt unit and the operation of the load based on the acquired information;

[0013] A power supply that provides power to the pan-tilt unit, load, and controller.

[0014] Compared with existing technologies, the mobile phone holder with a two-axis electric gimbal provided by this utility model sets up a mobile phone loading mechanism to position the gimbal in a camera coordinate system determined by the parameters of the external mobile phone camera mechanism. This allows the load to be fixedly mounted on the gimbal and rotate synchronously with it. When the load indicator mechanism, such as a laser pointer, or the ranging mechanism, such as a laser rangefinder, is loaded, the load rotates synchronously with the rotation of the gimbal. The position of the rotation center point in the camera coordinate system can be calculated based on the size parameters of the mobile phone holder and the parameters of the camera mechanism. This fully utilizes the existing depth measurement mechanism and color camera mechanism of the external mobile phone, eliminating the need for separate configuration of depth measurement mechanism and color camera mechanism to complete the user's indication from the image to the actual spatial point and spatial ranging of the image point. This effectively reduces the cost for users to achieve the indication from the image to the actual spatial point, and it is also easy to carry, meeting the user's application needs in different scenarios.

[0015] Furthermore, the mobile phone loading mechanism includes a support base, which includes a back plate and a tray. The back plate is fixedly connected to one side of the base, and the tray is vertically fixedly connected to the bottom of the back plate.

[0016] Furthermore, the mobile phone loading mechanism also includes a first clamping part, a second clamping part, and an elastic connecting rod; the first clamping part is fixedly connected to the back plate and has a first through hole for the elastic connecting rod to slide; one end of the elastic connecting rod passes through the first through hole and the other end is fixedly connected to the second clamping part; the second clamping part is telescopically connected to the first clamping part through the elastic connecting rod.

[0017] Furthermore, the mobile phone loading mechanism includes a first clamping part, a second clamping part, and a screw; the first clamping part is fixedly connected to the back plate and has a first screw hole that mates with the screw; the second clamping part has a second screw hole that mates with the screw; the screw passes through the second screw hole and is rotatably connected to the first screw hole, so that the second clamping part and the first clamping part are retractably connected.

[0018] Furthermore, the mobile phone loading mechanism also includes a magnetic chuck, which is mounted on the back panel and can magnetically attach to an external mobile phone.

[0019] Furthermore, the mobile phone loading mechanism includes a first clamping part and a second clamping part; the first clamping part is a U-shaped plate, with a U-shaped recess in its middle fixedly connected to the back plate, a rotating shaft at one end of its U-shaped port, and a lock seat at the other end; the second clamping part is a straight plate, with a shaft hole at one end, through which the rotating shaft passes, so that the second clamping part is rotatably connected to the first clamping part, and a locking member that cooperates with the lock seat at the other end, so that the second clamping part can rotatably engage the locking member with the lock seat to complete the locking and fixing.

[0020] Furthermore, the gimbal includes a horizontal rotating motor, a horizontal rotating bracket fixed on the bearing of the horizontal rotating motor for transmitting horizontal rotation, a vertical rotating motor disposed on the horizontal rotating bracket, and a vertical rotating bracket fixed on the bearing of the vertical rotating motor for transmitting vertical rotation, wherein the load is fixedly connected to the vertical rotating bracket.

[0021] Furthermore, the load is an indicator mechanism that rotates synchronously with the gimbal.

[0022] Furthermore, the load is a laser rangefinder pen, which rotates synchronously with the gimbal.

[0029] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings of the embodiments thereof.

[0030] To address the issue that existing remote pointing mechanisms require separate camera devices and gimbals to guide users from a point in a captured image to an actual point in space, resulting in high costs and inconvenience for remote spatial pointing and ranging, the inventors studied existing two-axis / three-axis gimbal brackets for fixed mobile phones. They discovered that when the mobile phone acts as the load of the gimbal, it rotates synchronously with the gimbal, and the position of the mobile phone in the world coordinate system changes continuously with the rotation. If applied to spatial pointing or ranging, it cannot accurately correlate the image coordinates of a pixel in the image captured by the mobile phone camera mechanism with the actual point in the world coordinate system, thus failing to meet the usage requirements in scenarios such as spatial pointing and ranging. Therefore, this utility model provides a mobile phone holder with a two-axis electric gimbal. The mobile phone holder has a gimbal mounted at a specific position on the holder and a load that rotates synchronously with the gimbal on the gimbal. The load is an indicating mechanism or a ranging mechanism. After obtaining an image of the target indication area of ​​the external mobile phone, the indicating mechanism can accurately indicate the actual three-dimensional point in space corresponding to any pixel point specified by the user in the image, or the ranging mechanism can measure the distance. It can make full use of the existing camera mechanism of the external mobile phone without the need to configure a separate camera mechanism to complete the user's indication or ranging from the image to the actual spatial point. This effectively reduces the cost for the user to achieve the indication or ranging from the image to the actual spatial point, and is easy to carry, which can meet the user's application in different scenarios.

Once the dimensions of the mobile phone holder and the parameters of the camera mechanism are determined, the coordinates of the rotation center point of the load 40 in the camera coordinate system can be determined, allowing for the mapping between pixel coordinates and three-dimensional spatial coordinates.
