[0032] In order to better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the specification drawings and specific implementation manners.

[0033] The schematic structural diagram of the shooting auxiliary device for the handheld eye image acquisition device of the present utility model is as shown in Figure 1-6 shown; among them, as shown in Figure 1 shown, it includes: an acquisition device 1 for acquiring images of the eyes, an auxiliary bracket 2 for assisting in eye image acquisition, a base 3 for protecting the handheld eye image acquisition device, and an anti-collision buffer box 4 for placing the auxiliary bracket and the base.

[0034] The auxiliary support 2 consists of two parts: including a support rod 23 for guiding the direction of the eyes of the person being collected and a support 24 for giving the person being collected an accurate fixed collection position. Among them, the small ball 8 on the support rod 23 creates a visual focus for the person being collected. Specifically, the small ball 8 is provided at the top of the support rods 23 on both sides.

[0035] In addition, when the support 24 is in use, the person being collected places their chin on the groove 5 on the support 24; at this time, the chin of the person being collected will contact the soft silicone pad 6; thereby, the utility model can provide comfortable support for the person being collected and avoid discomfort caused by long-term use.

[0036] Meanwhile, in order to ensure the stability of the auxiliary support 2 under various ground conditions, anti-slip pads 9 are provided at the four corners of the bottom surface of the support 24 of the auxiliary support for support.

[0037] Among them, the support rod is inserted inside the support, and its top is lower than the top of the support after contraction.

[0038] As one of the selections of the support rod, the support rod 23 uses a high-strength plastic material, which can maintain lightness and ensure firmness, ensuring the stability and durability of the support rod 23.

[0039] As one of the selections of the support rod, an electric lifting rod is used to automatically drive the small ball to move up and down.

[0040] To ensure the safety of the user, the small ball 8 is set as a protruding small ball for guiding the direction of the eyes of the person being collected to adapt to different collection requirements.

[0041] To improve the accuracy of the eye rotation angle, the small ball 8 is set as a multi-faceted sphere. When the user is required to look at different faces on the small ball 8, their eyes will rotate a certain angle; thereby, the small ball 8 can accurately guide the user's eyes to make small and fixed-angle rotations, improving the accuracy of detection.

[0042] The base 3 for protecting the handheld eye image acquisition device is used to store and protect the acquisition device 1 when it is not in use, and at the same time is provided with a flat fixing space 11 for placing an industrial tablet, which is convenient for the handheld device 1 to connect to the tablet to acquire images at any time through the USB cable 13 and keep the tablet computer stable.

[0043] The base 3 is provided with a special device fixing space 10 for placing the handheld acquisition device. The periphery of the device fixing space 10 is covered with a soft silicone pad, which can firmly fix the device and prevent it from moving and colliding during storage.

[0044] The bottom of the base is also equipped with an anti-slip pad 17 to ensure stability under various ground conditions. The base is made of high-strength plastic, which has good dust-proof, anti-pollution and shock-resistant properties, and can effectively protect the precision components of the device.

[0045] As Figure 6 shown, inside the anti-collision buffer box 4 for placing the auxiliary bracket and protecting the base, there is a base fixing space 18 for placing the base 3 that protects the acquisition device 1, and the auxiliary support fixing space 20 provided inside the anti-collision buffer box 4 is for placing the auxiliary support 2 to provide additional protection measures.

[0046] Around the base fixing space 18 and the auxiliary bracket fixing space 20 inside the anti-collision buffer box 4, there is a sponge pad 25, which can effectively absorb external impacts and further protect the precision components of the device.

[0047] The outside of the anti-collision buffer box 4 is wrapped with a leather shell 19 to prevent slipping and bumping.

[0048] On the outside of the anti-collision buffer box 4, there are a lock 21 and a handle 22. The setting of the handle 22 facilitates carrying and transportation; while the setting of the lock 21 can ensure that the anti-collision buffer box 4 after being locked protects the device from being damaged during transportation.

[0049] Working principle:

[0050] When it is necessary to use the acquisition device 1 for handheld eye image acquisition in a non-fixed place, the user first opens the lock 21 of the anti-collision buffer box 4 and takes out the auxiliary support 2 and the base 3 from it.

[0051] Then, put the tablet computer into the base side notch 15 of the base 3; at this time, connect the USB cable 13 of the acquisition device 1 to the tablet, and after connecting the tablet power cable 14 to the tablet, cover and fix the base side baffle 12 through the screw holes 16.

[0052] Furthermore, the person to be collected first leans the chin on the silica gel pad 6 in the groove 5; at this time, adjust the height of the support rod 23 so that the height of the small ball is level with the eyes of the person to be collected.

[0053] At this time, the user gives an instruction to the person to be collected to let them look at the small ball; hereby, images of different angles of the eyes can be collected. Among them, the anti-slip pads 9 provided at the four corners of the bottom surface of the support 24 of the auxiliary support 2 can ensure that the acquisition auxiliary support remains stable under various ground conditions.

[0054] After the eye image is captured, the user places the capture device 1 into the device fixing space 10 on the base 3, then shortens the support rod 23 of the auxiliary support 2 and places the auxiliary support bracket into the auxiliary support bracket fixing space; then, places the base 3 into the base fixing space 18, closes the lid of the anti-collision buffer box 4, and locks the lock 21.
