[0011] A collecting method of an image collecting device based on head attitude control, comprising the following steps:

[0012] Step (1): first, the staff wears the equipment, puts the head band on the head position, and puts the fixed flexible band on the chin position of the head to fix the equipment, avoids the situation that the equipment does not follow the rotation when the head rotates, and adjusts manually to ensure that the panoramic collecting probe on the front side faces the front of the staff;

[0013] Step (2): the panoramic image is shot by four panoramic probes, and the shot panoramic image is displayed on the surface of the transparent display screen; when the staff needs to clearly view the image of the transparent display screen, the dark arc-shaped baffle is pushed forward, so that the dark arc-shaped baffle is rotated to the front of the staff along the rotating semicircular groove, and the transparent display screen is blocked, so that the image on the surface of the transparent display screen is blocked from the external light, thereby being clearer; when the staff no longer needs to view the image of the transparent display screen, the dark arc-shaped baffle is pushed backward, so that the dark arc-shaped baffle is rotated to the rear of the staff along the rotating semicircular groove, so that the staff can directly observe the situation in front through the transparent display screen.

[0014] Step (3): when the staff rotates the head, the collecting table and the transparent display screen rotate with the head of the staff; when the staff needs to view the images of the transparent display screens on the two sides or the rear side, the micro motor is started to drive the driving gear to rotate, so that the driven gear ring is driven to rotate through the driving gear, and the transparent display screen is rotated at the bottom of the collecting table, so that the transparent display screens on the two sides or the rear side are rotated to the front of the staff, so that the staff does not need to rotate the head when viewing the images on the surface of the transparent display screens on the two sides or the rear side, thereby avoiding the influence of the triggered posture control on the content to be viewed.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0031] Please see Figures 1 to 6 An embodiment of the present invention provides an image acquisition method based on head posture control, including a head strap 1, four fixing blocks 2 fixedly installed on the surface of the head strap 1, an acquisition platform 3 on the outer side of each fixing block 2, a panoramic acquisition probe 5 on the outer side of each acquisition platform 3, a display screen mounting ring 7 at the bottom of the acquisition platform 3, and a transparent display screen 8 at the bottom of the display screen mounting ring 7.

[0032] The top of the display screen mounting ring 7 is provided with a rotating ring groove 12. The bottom of the front acquisition platform 3 is fixedly installed with a drive gear 15. The bottom of the other three acquisition platforms 3 are all fixedly installed with T-shaped rods 14. The T-shaped rods 14 and the drive gears 15 are movably inserted into the interior of the rotating ring groove 12. The interior of the rotating ring groove 12 is fixedly installed with a driven gear ring 17. The drive gears 15 are all meshed with the driven gear ring 17.

[0033] By cooperating with the active gear 15 and the driven gear ring 17, the device can be used to drive the active gear 15 to rotate via a micro motor, thereby driving the driven gear ring 17 to rotate and adjusting the position of the transparent display screen 8. This avoids the need for staff to turn their heads when viewing the images on the transparent display screen 8 on the sides or back, which would trigger posture control and affect the content to be viewed.

[0034] A semi-circular fixing plate 10 is fixedly installed on the outer surface of the display screen mounting ring 7 near the front side. The outer surface of the semi-circular fixing plate 10 is provided with a rotating semi-circular groove 13. Two dark-colored arc-shaped baffles 9 are movably installed at the bottom end of the semi-circular fixing plate 10. The dark-colored arc-shaped baffles 9 are in contact with the surface of the transparent display screen 8. A connecting arc plate 11 is fixedly installed at the top of each of the two dark-colored arc-shaped baffles 9. The connecting arc plate 11 is in contact with the outer surface of the semi-circular fixing plate 10. A sliding arc block 16 is fixedly installed on each connecting arc plate 11 near the rotating semi-circular groove 13. The sliding arc block 16 is slidably inserted into the interior of the rotating semi-circular groove 13.

[0035] With the cooperation of the transparent display screen 8 and the dark-colored curved baffle 9, when the staff needs to clearly view the image on the transparent display screen 8, the dark-colored curved baffle 9 can be pushed forward, causing it to rotate along the rotating semicircular groove 13 to a position in front of the staff, thus blocking the transparent display screen 8. At this time, the image on the surface of the transparent display screen 8 is blocked from external light by the dark-colored curved baffle 9, making it clearer. When the staff no longer needs to view the image on the transparent display screen 8, the dark-colored curved baffle 9 can be pushed backward, causing it to rotate along the rotating semicircular groove 13 to a position behind the staff, so that it no longer blocks external light. At this time, the staff can directly observe the situation in front of them through the transparent display screen 8, allowing them to move while acquiring images and avoiding restrictions on their movement.

[0036] Supplemental lights 4 are installed on the upper outer side of the collection platform 3, and a fixed flexible strap 6 is installed at the bottom of the head strap 1.

[0037] The front-side acquisition platform 3 is equipped with a micro motor, and the output end of the micro motor is connected to the drive gear 15 through a coupling.

[0038] The acquisition station 3 is equipped with an image acquisition system, which includes an IMU sensor, a distortion attitude compensation and correction module, an attitude cooperative detection module, and an image processing module.

[0039] The IMU sensor is used to measure the three-axis attitude angles and rotational acceleration of the head. The distortion attitude compensation and correction module is used to dynamically correct the head attitude angle error. The attitude coordination detection module is used to detect the angle of the head attitude and coordinate the adjustment of the transparent display screen 8 to display the image. The image processing module is used to optimize and adjust the image data captured by the panoramic acquisition probe 5.

[0040] An image acquisition method based on head posture control includes the following steps:

[0041] Step (1): First, the staff wears the equipment, puts the head strap 1 on the head, and puts the fixed flexible strap 6 on the chin of the head to fix the equipment and prevent the equipment from not rotating when the head rotates. The staff also manually adjusts the equipment to ensure that the panoramic acquisition probe 5 on the front side faces the staff.

[0042] Step (2): Take panoramic images of the surroundings using four panoramic acquisition probes 5 and display the captured panoramic images on the surface of the transparent display screen 8. When the staff needs to view the images on the transparent display screen 8 clearly, the dark arc-shaped baffle 9 can be pushed forward, so that the dark arc-shaped baffle 9 rotates along the rotating semi-circular groove 13 to the position in front of the staff, so that it blocks the transparent display screen 8. At this time, the images on the surface of the transparent display screen 8 are blocked by the dark arc-shaped baffle 9, making them clearer. When the staff no longer wants to view the images on the transparent display screen 8, the dark arc-shaped baffle 9 can be pushed backward, so that the dark arc-shaped baffle 9 rotates along the rotating semi-circular groove 13 to the position behind the staff, so that it no longer blocks the external light. At this time, the staff can directly observe the situation in front through the transparent display screen 8.

[0043] Step (3): When the staff turns their head, the acquisition platform 3 and the transparent display screen 8 will follow the staff's head. When the staff needs to view the images on the transparent display screen 8 on the sides or back, they can start the micro motor to drive the drive gear 15 to rotate, thereby driving the driven gear ring 17 to rotate, which in turn makes the transparent display screen 8 rotate at the bottom of the acquisition platform 3. This allows the transparent display screen 8 located on the sides or back to rotate in front of the staff, avoiding the need for the staff to turn their head when viewing the images on the surface of the transparent display screen 8 on the sides or back, which would trigger posture control and affect the content to be viewed.

[0044] Step (1) also includes the following steps when the worker turns their head:

[0045] Step (1.1): First, set the basic head posture rotation threshold in the posture coordination detection module, and use the IMU sensor to measure the three-axis posture angle and rotation acceleration of the head. When the head rotation angle exceeds the set threshold, the posture coordination detection module is triggered to coordinate the head rotation angle to adjust the transparent display screen 8 to display the image.

[0046] Step (2) of displaying the captured panoramic image on the surface of the transparent display screen 8 also includes the following steps:

[0047] Step (2.1): The distortion posture compensation and correction module detects the subtle movements of the worker's head and dynamically corrects the head posture angle error;

[0048] Step (2.2): The captured image is dynamically repaired and optimized by the image processing module so that a clear image is displayed on the surface of the transparent display screen 8.

[0049] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
