Description

[0002] With the continuous development of society and the rapid advancement of science and technology, the field of physical 3D modeling has ushered in new challenges and opportunities. In the past, the relatively backward manual modeling based on a single object picture and video was difficult to stand out among many technical means and attract the attention of the 3D model market. On the contrary, with the continuous innovation of 3D technology, converting objects into vivid and realistic 3D forms and displaying them through photographs is gradually becoming a key link in 3D display, and its importance is self-evident.

[0003] The 3D shooting technology currently known to the applicant mostly relies on manual operation in the process of collecting 3D materials of goods, which leads to a problem that cannot be ignored: the quality stability of photo collection is poor and difficult to control. In photo 3D modeling, the photo shows a spherical shape that wraps the object in three-dimensional space, and the shooting process may be interfered by various factors such as light, angle, equipment accuracy and operator proficiency. The final material obtained often has defects or deviations, which in turn has a serious negative impact on the subsequent modeling work. The 3D models of goods constructed based on these poor-quality materials are often unable to accurately restore the real details and characteristics of the goods, and it is difficult to present amazing visual effects. Naturally, it is impossible to effectively attract the attention of the 3D model market and achieve the expected results.

[0004] Therefore, people are in urgent need of a 3D modeling shooting system with high shooting quality and high 3D modeling accuracy. Summary of the invention

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] The purpose of the present invention is to provide a 3D modeling shooting system and a 3D modeling shooting method to solve the problems existing in the prior art, improve the shooting quality by designing an automated shooting system, and further improve the 3D modeling accuracy.

[0034] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] Please refer to Figure 1 to Figure 5As shown, a three-dimensional modeling shooting system is provided, including a shooting studio, a central storage table 10, a camera 8, a flash 4, an arc track 11, a transverse track 9, a radius track 7 and a central control device 16. The central storage table 10 is arranged in the shooting studio to rotate around its own axis, the flash 4 is arranged corresponding to the central storage table 10, the arc track 11 is arranged on the shooting studio, and the transverse track 9 is arranged on the arc track 11 through a driving mechanism to gradually move from a horizontal state to a vertical state, that is, the arc track 11 is at least 1 / 4 circle, so that the transverse track 9 can move from a horizontal state to a vertical state, and the driving mechanism is connected to the central control device 16 through a transmission line 15. The device 16 is electrically connected to realize automatic control, the radius track 7 is slidably set on the transverse track 9, the camera 8 is slidably set on the radius track 7, and the camera 8 is set toward the object to be photographed placed on the central storage table 10. The rotation of the central storage table 10 cooperates with the camera 8 moving along the arc track 11 to realize automatic acquisition of multi-angle images of the object to be photographed, and the overall shooting stability is high and the shooting quality is high; at the same time, the camera 8 can be adjusted in position through the radius track 7 and the transverse track 9, which can further improve the shooting quality and is suitable for objects to be photographed of different sizes; with the improvement of shooting quality, it is beneficial to improve the accuracy of the final three-dimensional modeling.

[0036] In this embodiment, a rotating motor is connected to the bottom of the central storage table 10, and the rotating motor is arranged in the shooting studio. The central storage table 10 and the object to be photographed placed on the central storage table 10 are driven to rotate by the rotating motor. In other embodiments, the central storage table 10 can also be driven to rotate by belt transmission, gear transmission, etc.

[0037] The shooting studio includes a frame and frosted background paper 14. The frosted background paper 14 is laid on the sides and bottom of the frame. The frosted background paper 14 is made of pure color PVC frosted background paper, which is white or black. A shooting port for the camera 8 to move is opened on the frame. The frosted background paper 14 is no longer set at the shooting port. Arc-shaped tracks 11 are set on the edges of both sides of the shooting port. The setting of the frosted background paper 14 creates a single background environment for shooting, which can further improve the shooting quality.

[0038] A black curtain 13 is arranged on the top of the frame to prevent the light from above from directly shining into the shooting studio and to prevent external light interference, thereby further improving the shooting quality.

[0039] When a shooting port is set, a black soft cloth can be placed at the shooting port. When shooting, the black soft cloth can be used to cover the shooting port to further prevent interference from external light and improve shooting quality.

[0040] Arc-shaped tracks 11 are arranged on both sides of the transverse track 9, and the matching structure between the transverse track 9 and the circular-shaped track 11 is as follows: electric slides 2 are arranged on both ends of the transverse track 9, a driving mechanism is arranged on the electric slide 2, the driving mechanism is connected to a gear 12 in transmission, an arc-shaped rack 121 is arranged on the circular-shaped track 11, and the gear 12 is meshed with the arc-shaped rack 121. When the driving mechanism drives the gear 12 to rotate, the electric slide 2 moves along the arrangement direction of the arc-shaped rack 121, thereby realizing the circular motion of the transverse track 9.

[0041] In order to improve the movement stability of the electric slide 2, an arc-shaped guide groove is provided on the arc-shaped track 11, and a guide wheel is provided on the electric slide 2. The guide wheel moves in the arc-shaped guide groove. As the movement stability of the electric slide 2 is improved, the stability of the camera 8 will also be improved, which is beneficial to improving the shooting quality.

[0042] Arc-shaped guide grooves may be provided on both sides of the arc-shaped track 11 , and a plurality of guide wheels may be provided on the electric slide 2 to cooperate with the arc-shaped guide grooves on both sides to guide from both sides, thereby further improving movement stability.

[0043] The driving mechanism is a stepper motor 3. To improve the movement accuracy, the stepper motor 3 can have a locking function through an external brake device or by using a holding torque to prevent the position from shifting after the movement is in place, thereby improving the movement accuracy.

[0044] In this embodiment, the sliding cooperation structure between the radius track 7 and the transverse track 9 is as follows: a pulley platform 5 is provided at the bottom of the radius track 7, and the pulley platform 5 is slidably connected with the transverse track 9. Specifically, a sliding groove is provided on the transverse slide rail, and a pulley is provided on the pulley platform 5. The pulley is slidably arranged in the sliding groove. A locking screw can be threadedly arranged on the pulley platform 5, and the locking screw passes through the pulley platform 5 and abuts against the transverse track 9 to complete the locking of the position of the pulley platform 5.

[0045] In this embodiment, the sliding cooperation structure of the camera 8 and the radius track 7 is as follows: a camera clamp seat 6 is slidably provided on the radius track 7, and the camera 8 is arranged on the camera clamp seat 6. Two vertical plates are slidably provided at the bottom of the camera clamp seat 6. The two vertical plates are located on both sides of the radius track 7. The distance between the two vertical plates is controlled by a clamp seat knob 17. The clamp seat knob 17 is equivalent to a screw rod. The screw rod has two threaded parts with opposite thread directions. The two threaded parts are respectively connected to a vertical plate. By rotating the clamp seat knob 17, the two vertical plates are controlled to move toward or away from each other. When they move toward each other until they abut against the radius track 7, position locking is achieved.

[0046] In other embodiments, the sliding fit structure between the radius track 7 and the transverse track 9 and the sliding fit structure between the camera 8 and the radius track 7 may adopt other sliding fit structures as long as the sliding fit can be achieved.

[0047] In order to further improve the shooting quality, the center of the circle of the camera 8 moving along the arc track 11 coincides with the center of the object to be photographed. The height of the camera 8 can be adjusted by adjusting the camera clamp 6 at different heights or connecting different numbers of camera clamps 6 in sequence.

[0048] The flash 4 is arranged in a ring shape around the camera head of the camera 8. Through the ring-shaped flash 4, light is emitted along the camera head of the camera 8 toward the object to be photographed, achieving an excellent shadowless effect and fundamentally eliminating photo defects caused by shadows, thereby effectively ensuring that the full-viewing angle acquisition task of the photo can be completed comprehensively and without omission, and improving the shooting quality.

[0049] The flashlight 4 can be linked with the camera 8. When the shutter of the camera 8 is pressed, the flashlight 4 lights up, and after the shooting is completed, the flashlight 4 turns off.

[0050] The three-dimensional modeling shooting system also includes a display 1, which is electrically connected to the camera 8 and the central control device 16 respectively, and the display 1 is used to display the shot image in real time.

[0051] The present invention also provides a 3D modeling shooting method of the above 3D modeling shooting system, comprising the following steps:

[0052] S1: placing the object to be photographed on the central storage table 10, and adjusting the position of the camera 8 on the transverse track 9 and the distance from the object to be photographed, and locking the position of the camera 8 after the adjustment is completed;

[0053] S2: The central control device 16 controls the central storage table 10 to rotate one circle, and during the rotation process, it pauses for a certain time (e.g., 1 to 2 seconds, the pause time is determined according to the shutter speed of the camera 8) every time it rotates a certain angle and takes a photo;

[0054] S3: After one rotation is completed, the central control device 16 controls the driving mechanism to drive the transverse track 9 to move upward along the arc track 11 by a certain angle and stop, and the central storage table 10 rotates one more circle. During the rotation process, it pauses for a certain time (e.g., 1 to 2 seconds, the pause time is determined according to the shutter speed of the camera 8) every time it rotates by a certain angle and takes a picture;

[0055] S4: Repeat step S3 until the transverse track 9 moves to the position directly above the object to be photographed.
