[0002] Combination fireworks are composed of multiple single tubes arranged and combined, and produce sound, light, color, floating objects and other effects when set off. The materials in each single tube of combination fireworks are usually automatically loaded by automated equipment, including the loading of gunpowder, the loading of paper, and the loading of effect inner tubes.

DETAILED DESCRIPTION

[0025] The following is the specific embodiment of the present application and in conjunction with the accompanying drawings, the technical scheme of the present application is further described, but the present application is not limited to these embodiments. In the following description, specific details such as specific configuration and components are provided only to help fully understand the embodiments of the present application. Therefore, it should be clear to those skilled in the art that various changes and modifications can be made to the embodiments described herein without departing from the protection scope of the present application. In addition, for clarity and brevity, the description of known functions and structures has been omitted.

[0026] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other.

[0027] The fireworks visual inspection device provided in the present application is used to inspect each fireworks tube on the combined fireworks after the filling process to determine whether the filling is qualified. Specifically, the fireworks visual inspection device can be used after the filling of gunpowder, the filling of paper, and the filling of the effect inner tube to inspect the corresponding fillings to confirm whether the filling is qualified.

[0028] An embodiment of the present application provides a fireworks visual detection device, which includes: an image acquisition component and an image processing component; the image acquisition component includes a mounting frame, and a camera connected to the mounting frame; the camera is installed at a fixed height, and is used to capture images of combined fireworks below; and the working distance corresponding to the mounting height of the camera can satisfy the requirement that multiple firework tubes on the combined fireworks are included in the captured field of view, so that the image captured by the camera includes multiple firework tube images; the image processing component is connected to the camera via a data transmission line, so as to identify and detect multiple firework tubes in the combined fireworks image captured by the camera.

[0029] Specifically, the camera is used to collect images of the combined fireworks below, and the image processing component is connected to the camera via a data transmission line. After the camera collects the image of the combined fireworks, it transmits it to the image processing component via the data transmission line. The image of the combined fireworks taken by the camera contains multiple firework tubes, and the image processing component can process and identify the image collected by the camera to determine whether each firework tube in the image is filled properly. The image processing component is a computer device with image processing function, having a storage chip and an image processing chip. In one embodiment, the image processing component is a PLC or an industrial computer, or other embedded devices with image processing and recognition capabilities.

[0030] The camera is installed at a fixed height to capture images of the combined fireworks below. In addition, the working distance corresponding to the installation height of the camera can satisfy the requirement that multiple firework tubes on the combined fireworks are included in the captured field of view, so that the captured image contains multiple firework tube images. Furthermore, the calculation formula for the field of view is as follows: Field of view (FOV) = working distance (WD) × CCD target model size (V or H) / focal length (f). Therefore, when the installation height of the camera is higher, the corresponding working distance is larger, the field of view is larger, and the number of firework tubes included is more.

[0031] like Figure 3 As shown, the F area shows the field of view of the camera, and multiple firework tubes are included in the F area; therefore, the image captured by the camera will include multiple firework tube images. In addition, the image captured by the camera can be processed and identified by the image processing component to determine whether each firework tube in the image is properly loaded. Based on the above settings, a camera can capture multiple firework tube images on a combined firework at one time, and the image processing component can identify and detect multiple firework tubes in one image, thereby effectively improving the efficiency of the detection device and reducing costs.

[0032] It should be noted that one or more cameras are arranged on the mounting frame. When the field of view of all cameras is superimposed to cover all the firework tubes on the combined fireworks, the image acquisition component does not need to be moved, and it is sufficient to maintain a fixed position to acquire images. When the field of view of all cameras is superimposed to be insufficient to cover all the firework tubes on the combined fireworks, it is necessary to move the camera for multiple image acquisitions. For the above two situations, one camera can acquire images of multiple firework tubes on the combined fireworks at one time, so that fewer cameras and / or fewer movements (including situations where no movement is required) can be used to achieve image acquisition and detection and identification of all firework tubes on the combined fireworks, thereby effectively improving the efficiency of the detection device and reducing costs.

[0033] refer to Figure 1-Figure 6, a fireworks visual detection device provided in an embodiment of the present application includes: an image acquisition component 10 and an image processing component 20. The image acquisition component 10 includes a mounting frame 11, and a camera 12 connected to the mounting frame 11; the camera 12 is installed at a fixed height, and is used to capture images of the combined fireworks below; and the working distance corresponding to the mounting height of the camera 12 can satisfy the requirement that the field of view captured includes multiple firework tubes on the combined fireworks, so that the image captured includes multiple firework tube images; the image processing component 20 is connected to the camera 12 via a data transmission line to identify and detect multiple firework tubes in the combined fireworks image captured by the camera 12. When the image acquisition component 10 remains stationary and the field of view of all cameras is superimposed to cover all the firework tubes on the combined fireworks, the image acquisition component does not need to move, and can capture images by maintaining a fixed position.

[0034] refer to Figure 1 and Figure 2 The fireworks visual detection device also has a support frame 30; the mounting frame 11 is connected to the support frame 30. The support frame 30 is fixedly installed or placed on the ground. Figure 1 and Figure 2 In the structure shown, the support frame 30 is placed on the ground. Here, the support frame 30 is placed on the ground, which is easy to install and more flexible to use without being bound to a specific device. Further, the bottom of the support frame 30 has a planar tripod 31; the tripod 31 is placed on the ground for support. The planar tripod 31 can achieve more stable support.

[0035] refer to Figure 4 In one embodiment of the present application, a plurality of cameras 12 are arranged on the mounting frame 11, and the field of view captured by each camera 12 includes a plurality of firework tubes in a corresponding area on the combined fireworks, and the fields of view captured by the plurality of cameras 12 jointly cover all firework tubes on the combined fireworks; the image processing component 20 is connected to the plurality of cameras 12 via a data transmission line to identify and detect all firework tubes on the combined fireworks captured by the plurality of cameras 12.

[0036] Specifically, during one detection and identification process, the multiple cameras 12 included in the image acquisition component perform one image acquisition on the combined fireworks below, and correspondingly obtain multiple images. Since the fields of view captured by the multiple cameras 12 cover all the firework tubes on the combined fireworks together, all the firework tubes are included in the above multiple images. After acquiring the multiple images captured by the above multiple cameras 12, the image processing component 20 can identify and detect all the firework tube images of the combined fireworks to determine whether the filling of each firework tube on the combined fireworks is qualified.

[0037] In one embodiment of the present application, multiple cameras 12 are arranged in a vertical and horizontal array. Figure 4 ,exist Figure 4 In the structure shown, the cameras 12 on the mounting frame 11 are arranged in a 3×3 manner, with 3 rows and 3 columns.

[0038] In one embodiment of the present application, the image acquisition assembly 10 further includes a plurality of connection sockets 13, and the plurality of connection sockets 13 correspond to the plurality of cameras 12 one by one; the cameras 12 are mounted on the mounting frame 11 through the corresponding connection sockets 13. Furthermore, the connection position of the connection sockets 13 on the mounting frame 11 is adjustable. Therefore, the position of each camera can be fine-tuned by adjusting the position of the connection sockets 13, which is convenient for debugging during installation or adjustment when applied to new products.

[0039] refer to Figure 4-Figure 6 In one embodiment of the present application, the mounting frame 11 is a plate-like structure and is in a horizontal state, on which a plurality of parallel long strip mounting grooves 111 are arranged at intervals, and on both sides of each mounting groove are arranged long strip connecting holes 112 extending in the same direction. The connecting seat 13 includes a first connecting portion 131 and a second connecting portion 132; the first connecting portion 131 is located in the long strip mounting groove 111, and is used to connect with the camera 12; the second connecting portion 132 spans the corresponding long strip mounting groove 111, and is connected to the mounting frame 11 by bolts, and the connecting bolts are installed in the long strip connecting holes 112 on both sides of the corresponding long strip mounting groove 111. Here, since the connecting bolts are installed in the long strip connecting holes 112 on both sides of the corresponding long strip mounting groove 111, the installation position of the connecting seat 13 can be adjusted along the long strip connecting holes 112.

[0040] In one embodiment of the present application, a camera 12 is arranged on the mounting frame 11, and the field of view captured by the camera 12 includes all firework tubes on the combined fireworks; the image processing component 20 is connected to the camera 12 via a data transmission line to identify and detect all firework tubes on the combined fireworks captured by the camera 12.

[0041] Specifically, during one detection and recognition process, the image acquisition component includes a camera that acquires an image of each of the combined fireworks below, and obtains one image accordingly. Since the field of view captured by a single camera 12 includes all the firework tubes on the combined fireworks, all the firework tubes are included in one image. After acquiring one image captured by a single camera 12, the image processing component 20 can identify and detect all the firework tube images of the combined fireworks to determine whether the filling of each firework tube on the combined fireworks is qualified.

[0042] In the embodiment of the present application, the working distance corresponding to the installation height of the camera can satisfy the requirement that the field of view captured includes multiple firework tubes on the combined fireworks, so that the captured image includes multiple firework tube images; the image processing component is connected to the camera via a data transmission line to identify and detect multiple firework tubes in the combined fireworks image captured by the camera. Based on the above settings, a camera can capture multiple firework tube images on the combined fireworks at one time, and the image processing component can identify and detect multiple firework tubes in one image, thereby effectively improving the efficiency of the detection device and reducing costs.

[0043] The embodiment of the present application also provides a fireworks production line, which includes: the fireworks visual inspection device provided in the previous part. The fireworks production line includes a gunpowder filling device, a paper baba filling device, and an effect inner tube filling device.
