Description

Technical Field

[0001] This invention relates to the field of object image acquisition technology, and in particular to a device and method capable of automatically capturing images of objects from multiple angles while suspended in the air and generating 3D interactive models. Background Technology

[0002] Currently, multi-angle displays of goods or exhibits typically rely on manual handheld or rotating camera photography. Manual photography suffers from low efficiency and inconsistent angles; while rotating camera photography can acquire multi-angle images, the object's base is obscured by the rotating platform, preventing the acquisition of shadow-free and unobstructed bottom images. Therefore, there is an urgent need for a device that can automatically and precisely control the shooting timing to acquire six-sided images of the object with no obstructions and a clean background. Summary of the Invention

[0003] The purpose of this invention is to provide an automatic multi-angle shooting device and method for suspending objects, which can accurately capture instantaneous images of objects when they are completely detached from their supports and suspended in mid-air, and generate multi-angle interactive views through algorithms.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: An automatic multi-angle shooting device for suspended objects includes: a housing with a feeding port at the top for feeding objects; a cycloidal slide inclinedly disposed within the housing, with its upper end receiving the feeding port and its lower end forming a discharge port, the inner wall of the cycloidal slide having a cycloidal trajectory arc extending along the direction of the object's descent; sensors symmetrically disposed at the discharge port along a horizontal plane for sensing the passage of the object; multiple cameras fixedly mounted on the inner wall of the housing, facing the trajectory area traversed by the object as it slides down the slide; a control unit electrically connected to the sensors and cameras, which, upon determining that the object has completely entered the shooting area based on changes in the sensing signals, triggers the multiple cameras to simultaneously capture images; and a receiving basket disposed below the housing at a diagonal position from the feeding port in a vertical plane.

[0005] Furthermore, the longitudinal cross-sectional profile of the bottom wall of the cycloidal slide is a cycloidal curve; the sensor is a through-beam or reflective infrared sensor, and the control unit triggers a delayed photo capture when it determines that the object has returned from the state of being blocked by the sensor to an unblocked state; the number of the multiple cameras is six, which are respectively installed on the front, back, left, right, top, and bottom walls.

[0006] Furthermore, the present invention also includes a lighting system, including LED light strips and light shields arranged on the four side seams of the housing; the control unit is an embedded motherboard, which automatically maps the images from the front, back, left, right, top and bottom perspectives onto the corresponding faces of a virtual three-dimensional cube after triggering the shooting, generating a 3D interactive page that supports browser access, dragging, rotation and scaling.

[0007] The beneficial effects of this invention are: The images are clean and unobstructed: the object is photographed while it is completely suspended in the air, and there are no platforms, transparent plates or fingers obstructing the view from any of the six angles. In particular, the bottom view can fully show the lower surface of the object, which is something that traditional methods cannot achieve.

[0008] Precise triggering: Only a pair of sensors are needed at the discharge port. The logic is simple. The sensor is triggered as soon as the tail of the item leaves the object. The response is extremely fast, ensuring that the optimal posture of the item entering the falling area is captured.

[0009] High efficiency in digital data acquisition: With the help of six cameras and 3D mapping algorithms, high-quality, blind-angle-free 3D digital models of goods can be generated directly without the need for a rotating platform, which greatly improves the efficiency of digital data acquisition of goods.

Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0018] Example 1: As Figures 1 to 3 As shown in the figure, this embodiment discloses an automatic multi-angle shooting device for suspended objects.

[0019] In use, the operator puts the item to be photographed into the feeding port (15) at the top of the box (1). The item falls into the inclined cycloidal slide (9). Since the cycloidal slide (9) has a cycloidal trajectory arc surface, the linear velocity of the item tends to change smoothly when it slides down along the arc surface, avoiding bouncing at the end. At the same time, the baffles (14) on both sides of the slide can prevent the item from falling out from the sides of the slide.

[0020] When the item slides to the discharge port at the lower end of the cycloidal slide (9), a pair of infrared sensor transmitters (11) and receivers (10) are provided at the discharge port. The item will block the infrared light path when it passes by.

[0021] The control unit (7) receives signals from the sensor in real time. When the tail of the item completely passes through the discharge port and the light path changes from "obstructed" to "unobstructed", the control unit (7) determines that the item has completely entered the shooting area. Subsequently, the control unit (7) triggers a preset millisecond delay and controls the six cameras (6 front wall cameras, 2 rear wall cameras, 8 left wall cameras, 13 right wall cameras, 12 top wall cameras, and 5 bottom wall cameras) installed on the inner wall of the box (1) to perform high-precision capture simultaneously. The preset delay time T satisfies the formula: T = (H / v) - t0, where H is the projected distance from the end of the slide to the center point of the shooting area on the horizontal plane, v is the initial velocity of the item when it is discharged, and t0 is the mechanical / electronic shutter delay of the camera.

[0022] Since the six cameras correspond to the front, back, left, right, top, and bottom of the object respectively, a complete six-sided texture map of the object can be obtained when it is without any support.

[0023] After the snapshot is taken, the item continues to fall and eventually enters the receiving basket (4) located at the bottom of the box, diagonally opposite the feeding port (15). The receiving basket (4) is equipped with a flexible buffer layer and is designed as a drawer, which can be pulled out from the side of the box to retrieve the item.

[0024] During the image processing stage, the control unit (7) uses the acquired six-sided image as a texture to automatically map it to the virtual three-dimensional cube model, generating an interactive 3D webpage that supports dragging and scaling, and uploading it to a designated cloud server in real time through the built-in Wi-Fi module of the embedded motherboard for use by e-commerce platforms or product display systems.

[0025] The lighting component (3) uses high color rendering index LED light strips and is covered with soft light material to ensure the color accuracy and clarity of the image.

[0026] Figure 6 This is a time sequence diagram, showing the time order of the object sliding down, sensor signals, and camera signals.

[0027] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
