[0002] To capture an object from all angles without blind spots and create a panoramic image, multiple cameras at different angles are typically used to capture images of the object. These images are then stitched together to form a complete spherical image. The cameras at different angles often capture a series of images in concentric circles, and then specialized image processing software is used to stitch these images together into a complete 360-degree panoramic image.

[0003] When multiple cameras at different angles are shooting, there will be some overlap due to factors such as installation position and field of view. Since the cameras do not have an automatic cropping function, in order to avoid the overlap affecting the stitched image information and causing the panoramic image to be disordered, the existing technology uses algorithms to stitch the images. The stitching process requires high computing power and consumes a lot of computer resources. Summary of the Invention

[0045] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Well-known modules, units, and their connections, links, communications, or operations are not shown or described in detail. Furthermore, the described features, architectures, or functions can be combined in any way in one or more embodiments. Those skilled in the art should understand that the various embodiments described below are only for illustrative purposes and not for limiting the scope of protection of the present invention. It is also readily understood that the modules, units, or processing methods in the various embodiments described herein and shown in the accompanying drawings can be combined and designed in various different configurations. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] The definitions of various terms or methods used in the following embodiments are, except where logically impossible, generally defined as broad concepts that can be implemented under the premise of the content disclosed in the embodiments. Under this understanding, all specific subordinate limitations of the terms or methods should be considered as part of the invention and should not be narrowly interpreted or biased simply because the specification does not disclose such a specific limitation. Similarly, provided that it is logically feasible, the order of the steps in the method is flexible and varied, and all specific subordinate limitations in the broad concepts of various terms or methods fall within the scope of protection of this invention.

[0048] In existing cropping devices, to obtain a 360-degree panoramic image of an object, multiple cameras at different angles typically capture images of the object. The image processing module in the main controller, such as a GPU, then stitches the images together. This process achieves comprehensive, unobstructed imaging of the object, creating a complete spherical image. The cameras at different angles often capture a series of images in concentric circles, and specific image processing software controls the corresponding image processing module to stitch these images together into a complete 360-degree panoramic image.

[0049] In the process of conceiving and implementing this application, the inventors discovered at least the following problems: When multiple cameras at different angles are shooting, there will be a certain degree of overlap due to factors such as installation position and field of view. Since the cameras do not have an automatic cropping function, in order to avoid the overlap affecting the stitched image information and causing the panoramic image to be disordered, the existing technology uses algorithms to stitch the images, which requires high computing power and consumes a lot of computer resources.

[0050] It is known that, due to the limited computer resources, using existing algorithms for stitching often leads to computer lag and very slow processing. Furthermore, due to the lag, the image processing is often not very precise, and the identification of objects is often incorrect, resulting in significant limitations of existing panoramic image stitching solutions.

[0051] Therefore, the present invention proposes a cutting method; it is understood that the cutting device is provided with a control device for storing and executing the following method. The control device can be implemented by a main controller, such as MCU (Microcontroller Unit), DSP (Digital Signal Processor), FPGA (Field Programmable Gate Array), SOC (System On Chip), etc.

[0052] Reference Figures 1 to 7 As shown, Figure 1 This is a flowchart illustrating an embodiment of the cutting method of the present invention; Figure 2 This is a schematic flowchart of another embodiment of the cutting method of the present invention; Figure 3 This is a flowchart illustrating another embodiment of the cutting method of the present invention; Figure 4 This is a flowchart illustrating another embodiment of the cutting method of the present invention; Figure 5 This is a flowchart illustrating another embodiment of the cutting method of the present invention; Figure 6This is a schematic flowchart of another embodiment of the cutting method of the present invention; Figure 7 This is a flowchart illustrating another embodiment of the cutting method of the present invention; Figure 8 This is a schematic diagram of the device that enables the cutting method of the present invention to perform its functions.

[0053] Reference Figure 1 , Figure 1 This is a flowchart illustrating an embodiment of a cutting method according to the present invention. In one embodiment, the cutting device includes a laser rangefinder, and multiple cameras are arranged around the laser rangefinder. The cutting method includes the following steps:

[0054] S100: Obtain image information captured by multiple cameras at the same time, the location of objects in the image information, and the intersection vertices of adjacent image information.

[0055] S200, Crop the overlapping image information from the intersection vertex to the location range of the item.

[0056] In this embodiment, the number of cameras is at least two or more. First, multiple cameras are activated simultaneously to capture images. After capturing images, a laser rangefinder detects the distance to the object, and then obtains the field of view and spatial distance of adjacent cameras. The field of view is the area that the camera can capture. The field of view of adjacent cameras can be the same or different. In this embodiment, please refer to... Figure 8 As shown, cameras with the same field of view are used to photograph the object. The intersection vertex determined by these cameras is the median line between the two cameras, which allows for faster identification of the intersection area and the location requiring cropping. Figure 8 Point F in the diagram represents the location of the laser rangefinder. Typically, during filming, the object is positioned directly in front of point F. The distance between the intersecting vertex and point F is already determined. Therefore, it is only necessary to obtain the distance from point F to the object's location. Assuming the object's location is point B, the camera's location, i.e., points D and E, combined with points A and B, is used to enclose the area. The enclosed area is the cropping region. After cropping this part, overlapping image information can be removed. The implementation process is simple and reliable, and can be completed without relying on algorithms.

[0057] The control device first controls multiple cameras to capture images simultaneously, then identifies the object information in the images, and tests the distance to the objects using a ranging device. In addition, by acquiring the field of view of the cameras already stored in the memory and the spatial distance between adjacent cameras, the intersection vertex between multiple adjacent cameras is obtained. Based on the intersection vertex and the position of the object, when the distance to the object position is greater than the distance to the intersection vertex, the overlapping image information is cropped. The implementation process is simple and reliable and can be completed without relying on algorithms.

[0058] Furthermore, it is understandable that the control device can also store the stitching processing information currently stored in the main controller, such as the position of the cross vertices, so that after the camera finishes capturing the image, it can read the stitching processing information stored in the control device, obtain the position of the cross vertices, and perform the cropping operation on the image, thereby cropping out the required image, making the process simple and reliable, and can be completed without relying on algorithms.

[0059] This embodiment uses multiple cameras around a laser rangefinder to acquire image information captured by the multiple cameras simultaneously. The location of the object in the image information is then determined, and the intersection vertices of adjacent image information are identified. Finally, the overlapping image information within the range from the intersection vertex to the object location is cropped. The cropping distance is determined by the distance from the intersection point to the captured object. After calculating this distance, the desired image can be cropped. The implementation process is simple and reliable, and can be completed without relying on algorithms.

[0060] Furthermore, refer to Figure 2 Another embodiment of the present invention provides a cutting method based on the above. Figure 1 In the illustrated embodiment, the step of obtaining the intersection vertices of adjacent image information includes:

[0061] S110: Obtain the field of view of the multiple cameras and the spatial distance between adjacent cameras.

[0062] S120. Determine the intersection vertices of adjacent image information based on the field of view and spatial distance.

[0063] In this embodiment, the field of view of the camera is obtained. This field of view is related to the camera's focal length. Generally, to better capture panoramic images, a camera with a shooting angle of 90° or more is preferred. Based on the machine's factory information, the spatial distance between adjacent cameras is obtained. The cropped image mainly consists of overlapping images between adjacent cameras. It is understood that to save on the number of cameras installed, the camera angle is generally wide-angle, and there will be no overlap between images captured by three cameras; at most, only two adjacent cameras will overlap. Based on the determined field of view and spatial distance, the intersection vertices of adjacent image information can be calculated relatively easily. These intersection vertices are as follows: Figure 8 The location of point A shown can better determine the position where the image information needs to be cropped, and its reliability is stronger.

[0064] As a preferred option rather than a specific limitation, the step of obtaining the field of view of the multiple cameras and the spatial distance between adjacent cameras specifically includes: the spatial distance being the arc length of the adjacent cameras around the laser rangefinder.

[0065] In this embodiment, since the outer shell of the laser rangefinder is cylindrical, when the camera is located on the periphery of the laser rangefinder, the distance between them is the arc length of the periphery of the laser rangefinder. By obtaining the arc length as the spatial distance, the position of the intersection vertex can be better determined, thereby more accurately and reliably determining the position to be cut. The implementation process is simple and reliable and can be completed without relying on algorithms.

[0066] Furthermore, refer to Figure 3 Another embodiment of the present invention provides a cutting method based on the above. Figure 1 The embodiment shown includes the following steps for acquiring image information captured simultaneously by multiple cameras and the location of objects within the image information:

[0067] S130. Acquire image information captured by multiple cameras at the same time, and identify the location of items in the image information.

[0068] S140. Based on the image information and the position of the object, control the laser rangefinder to emit a laser signal to measure the distance to the object in front of the laser rangefinder.

[0069] In this embodiment, by acquiring image information captured by multiple cameras simultaneously and determining the position of objects in the image information, the laser rangefinder is activated to emit a laser signal to measure the distance from the object's position to the laser head of the laser rangefinder. This allows for a better determination of whether the object's distance is greater than the distance of the intersection vertex. If the object's distance is less than or equal to the distance of the intersection vertex, no cropping is required, and the image is invalid. The object needs to be rearranged and a second shot taken to obtain the required image information. This method offers greater reliability and stability.

[0070] Furthermore, refer to Figure 4 The present invention also provides a cutting method in one embodiment, based on the above. Figure 1 The illustrated embodiment includes the step of cropping the overlapping image information from the intersection vertex to the location of the item, comprising:

[0071] S150. Generate a first image range based on the positions of the adjacent cameras, the distance to the object, and the intersection vertex.

[0072] S160, Crop the overlapping images within the first image range.

[0073] In this embodiment, a first image range is generated based on the positions of adjacent cameras, the distance to the object, and the intersecting vertices. This first image range is the overlapping area enclosed by the cameras, the intersecting vertices, and the object's position. Please refer to [reference needed]. Figure 8 As shown, point F is the location of the laser rangefinder. Generally, during shooting, the object is placed directly in front of point F. The distance between the intersection vertex and point F is already determined. Therefore, it is only necessary to obtain the distance from point F to the object's location. Assuming the object's location is point B, and using the camera's location, i.e., points D and E, connect the positions of two adjacent cameras with the positions of points A and B to generate an enclosed area. The enclosed area is the first image range. The image in the first image range is also the overlapping image information. After cropping this part, the overlapping image information can be removed. The implementation process is simple and reliable and can be completed without relying on algorithms.

[0074] Furthermore, refer to Figure 5 Another embodiment of the present invention provides a cutting method based on the above. Figure 1 In the illustrated embodiment, the cutting method further includes:

[0075] S300: Obtain actual ambient lighting information.

[0076] S400: Based on the actual ambient lighting information and the preset ambient lighting information, determine that the light intensity is insufficient.

[0077] S500: When the light intensity is insufficient, control the supplementary light to start the supplementary lighting operation.

[0078] In this embodiment, considering that panoramic images of objects are not always captured in a fixed lighting environment—perhaps outdoors or indoors—insufficient lighting can easily result in dark images and unclear objects. Therefore, supplementary lighting is needed to illuminate the object's surface for better image capture. It's understood that if excessive light prevents shooting, it's difficult to adjust the light intensity, and the control device in this embodiment doesn't employ complex algorithms. Therefore, when excessive ambient light is detected, the shooting function is disabled, and an audio-visual alarm is activated to alert the user. Specifically, this embodiment adjusts the supplementary lighting intensity based on the specific lighting conditions to achieve optimal light intensity; the darker the environment, the stronger the supplementary light. More specifically, multiple supplementary lights at different angles can be used to ensure optimal light intensity regardless of the shooting angle. This process is simple and reliable, requiring no algorithmic support.

[0079] Furthermore, refer to Figure 6 Another embodiment of the present invention provides a cutting method based on the above. Figure 5 The illustrated embodiment, specifically includes the step of presetting ambient lighting information:

[0080] S410. Divide the first brightness information in the ambient light information into multiple brightness groups, wherein the difference between any two pieces of the first brightness information in each brightness group is less than a preset difference.

[0081] S420. Determine the supplementary light intensity corresponding to each of the aforementioned illumination intensity groups.

[0082] In this embodiment, the brightness of the light source is adjusted according to the lighting conditions. The darker the environment, the stronger the supplementary light. Different light intensity information is preferentially divided into multiple brightness groups, such as 1-50 cd, 51-100 cd, etc., and the difference between any two of the first brightness information in a group is less than a preset difference. The preset difference can be adjusted according to the user's requirements for lighting accuracy. The corresponding supplementary light intensity is determined according to the light intensity required during shooting. For example, if the ambient light intensity is 200 cd during shooting, but 500 cd is required, the supplementary light intensity for shooting can be simply determined to be 300 cd. Of course, supplementary light can also be applied to objects according to the supplementary light values ​​required at different angles. By calculating the supplementary light threshold required at each angle and adjusting the brightness of the supplementary lights at different angles, the supplementary lights at different angles can be controlled to start the supplementary light operation to achieve better supplementary light effect.

[0083] Furthermore, refer to Figure 7 Another embodiment of the present invention provides a cutting method based on the above. Figure 5 The embodiment shown includes the following steps for obtaining actual ambient light information:

[0084] S310. Obtain the second brightness information from the actual ambient lighting information.

[0085] The step of determining insufficient light intensity based on actual ambient light information and preset ambient light information specifically includes:

[0086] S430. Compare the second brightness information and the first brightness information. If the second brightness information is less than any of the first brightness information, determine that the light intensity is insufficient.

[0087] The step of controlling the supplementary lighting to start supplementary lighting when the light intensity is insufficient specifically includes:

[0088] S510. When the light intensity is insufficient, determine the light intensity group that matches the second brightness information, and control the supplementary light to start the supplementary lighting operation according to the supplementary light intensity.

[0089] In this embodiment, to improve the supplementary lighting effect, a second brightness information from the ambient light information is used. This second brightness information includes overall brightness information or brightness information at different angles. Since an object placed in one position is affected by natural or artificial light, resulting in uneven lighting, the directly captured photo will have many dark areas, meaning the contrast between light and dark in the photo is too large, leading to a poor panoramic image effect. Therefore, it is necessary to compare the second brightness information from the actual ambient light information with the preset first brightness information. The first brightness information is a brightness value indicating insufficient light intensity, and its maximum brightness value is a critical value, which is assumed to indicate sufficient light intensity. Only when the second brightness information is less than the first brightness information will it be determined that the light intensity is insufficient, and a corresponding illumination intensity group will be matched. Based on the second brightness information, a matching illumination intensity group is determined to ensure that the best light intensity can be achieved regardless of the angle from which the object is photographed. The implementation process is simple and reliable and can be completed without relying on algorithms.
