However, cameras have limited shooting range. To achieve comprehensive and clear monitoring, multiple cameras are usually required to monitor different areas of the vehicle separately. This results in higher equipment costs, and each camera needs to be matched with the vehicle's structural space and have its wiring designed during the overall vehicle design phase, leading to higher design costs.

[0011] Optionally, the image acquisition device is connected to the support module via at least two telescopic rods, and the image acquisition device rotates by the extension and retraction of each telescopic rod.

[0012] To achieve the above objectives, this application provides an image acquisition method, which is applied to the image acquisition system described above, and includes the following steps:

[0013] The image acquisition module acquires at least one local image of a preset spatial region during the movement along the magnetic levitation track.

[0014] Based on each of the local images, a three-dimensional spatial image of the preset spatial region is generated.

[0015] Optionally, before the step of acquiring at least one local image of a preset spatial region via the image acquisition module during movement along the magnetic levitation track, the method further includes:

[0016] In response to a voice command to activate the image acquisition system, the image acquisition system is activated, causing the image acquisition module to move along the magnetic levitation track;

[0017] And / or, after the step of activating the image acquisition system, the method further includes:

[0018] In response to a voice command to shut down the image acquisition system, the image acquisition system is shut down.

[0019] Optionally, the step of activating the image acquisition system in response to a voice command to activate the image acquisition system includes:

[0020] The image acquisition system is subjected to performance testing, wherein the performance testing includes at least one of magnetic levitation performance testing, image acquisition device rotation performance testing, and image acquisition performance testing;

[0021] If the performance test passes, the image acquisition system is activated in response to a voice command to activate the image acquisition system.

[0022] Optionally, the image acquisition system further includes an image display device, and after the step of generating a stereoscopic spatial image of the preset spatial region based on each of the local images, it further includes:

[0023] The image display device outputs and displays the three-dimensional spatial image.

[0024] Optionally, after the step of outputting and displaying the stereoscopic spatial image through the image display device, the method further includes:

[0025] In response to a stereoscopic spatial image operation command, the stereoscopic spatial image is subjected to image transformation processing to obtain a region image, wherein the image transformation processing includes scaling processing and rotation processing;

[0026] The image display device outputs and displays the image of the area.

[0027] This application also provides an electronic device, which is a physical device, comprising: a memory, a processor, and a program of the image acquisition method stored in the memory and executable on the processor.

[0028] This application also provides a storage medium, which is a computer-readable storage medium, on which a program for implementing an image acquisition method is stored.

[0029] This application provides an image acquisition method, system, electronic device, and storage medium. The image acquisition system is applied to a vehicle and includes: a magnetic levitation track fixedly mounted on the vehicle body; an image acquisition module magnetically connected to the magnetic levitation track for acquiring at least one local image of a preset spatial region during movement along the magnetic levitation track; and a control module communicatively connected to the image acquisition module for obtaining each of the local images from the image acquisition module and generating a three-dimensional spatial image of the preset spatial region based on each of the local images. Magnetic levitation enables the image acquisition module to operate at high speed on a magnetic levitation track. Therefore, only a magnetic levitation track needs to be installed on the vehicle body corresponding to the preset spatial area requiring image acquisition. The image acquisition module can then move along the track to acquire images of the preset spatial area. Because the image acquisition module can operate at high speed on the magnetic levitation track, even if the preset spatial area is large, such as including the entire outer perimeter of the vehicle body or the entire interior of the cabin, one or more images of a large area can be acquired in a very short time. At least one of the acquired images can then be stitched together to form a three-dimensional spatial image of the preset spatial area, achieving relatively comprehensive monitoring of a large preset spatial area through a single camera. This overcomes the limitations of limited camera shooting range. To achieve comprehensive and clear monitoring, multiple cameras are usually required to monitor different areas of the vehicle, resulting in high equipment costs. Furthermore, the design of each camera requires spatial matching and wiring design during the vehicle design phase, leading to high design costs. This approach saves on both equipment and design costs for vehicle monitoring. Attached Figure Description

[0039] The purpose, features, and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0040] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, 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, and not all embodiments. 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.

[0041] The image acquisition system described above is applied to vehicles. With the development of technology, cameras have gradually become a standard feature in vehicles, enabling more comprehensive and clearer monitoring of occupants, cargo, and the internal and external environment. However, cameras have limited shooting range. To achieve comprehensive and clear monitoring, multiple cameras are usually required to monitor different areas of the vehicle. Application scenarios requiring image acquisition on vehicles include one or more of the following: monitoring of in-vehicle personnel, monitoring of in-vehicle cargo, and monitoring of the external environment. For example, cameras can be installed near the A-pillar (the connecting pillar between the left and right front of the vehicle and the front compartment), the steering wheel, or the rearview mirror to monitor driver fatigue. Cameras can be installed inside the passenger compartment to monitor cargo stored there to prevent loss. Four or more panoramic cameras can be installed outside the vehicle to capture images of the surrounding environment, which can then be stitched together to create a panoramic view, monitoring the external environment and expanding the driver's field of vision during driving and parking, making it easier for the driver to understand the external environment.

[0042] Therefore, as vehicle functions increase, more image acquisition equipment is required, leading to higher equipment costs. Furthermore, the design phase of the entire vehicle necessitates spatial matching and wiring design for each camera within the vehicle's structure, resulting in significant design costs. On the other hand, fixed-position cameras offer limited flexibility in image acquisition. For instance, when monitoring cargo within the vehicle compartment, a large amount of cargo may obstruct the camera's field of view, making it impossible to monitor the obstructed area.

[0043] Based on this, this application proposes an image acquisition method, system, electronic device, and storage medium. The image acquisition system is applied to a vehicle and includes: a magnetic levitation track fixedly mounted on the vehicle body; an image acquisition module magnetically connected to the magnetic levitation track for acquiring at least one local image of a preset spatial region during movement along the magnetic levitation track; and a control module communicatively connected to the image acquisition module for obtaining each of the local images from the image acquisition module and generating a three-dimensional spatial image of the preset spatial region based on each of the local images. Magnetic levitation enables the image acquisition module to operate at high speed on a magnetic levitation track. Therefore, it is only necessary to arrange the magnetic levitation track on the vehicle body corresponding to the preset spatial area where image acquisition is required. The image acquisition module can then operate along the track to acquire images of the preset spatial area. Since the image acquisition module can operate at high speed on the magnetic levitation track, even if the preset spatial area is large, such as including the entire outer perimeter of the vehicle body or the entire interior of the carriage, one or more images of a large area can be acquired in a very short time. At least one of the acquired images can then be stitched together to form a three-dimensional spatial image of the preset spatial area, enabling relatively comprehensive monitoring of a large area of ​​the preset spatial area through a single camera. Even if there are obstructions in some areas, the image acquisition module can acquire images of the preset spatial area from multiple angles as it operates along the track. If part of the field of view is obstructed at a certain angle, the field of view can be supplemented from other angles. This overcomes the technical shortcomings of increasing image acquisition equipment costs as vehicle functions increase, requiring more camera configurations and wiring designs for each camera during the vehicle design phase, resulting in high design costs, and the limited flexibility of fixed-position cameras for image acquisition. It saves on equipment and design costs for vehicle monitoring and improves the flexibility of image acquisition.

[0044] Example 1

[0045] This application provides an image acquisition system. In a first embodiment of the image acquisition system of this application, refer to... Figure 1 The image acquisition system is applied to a vehicle and includes:

[0046] Magnetic levitation track 10, which is fixedly installed on the vehicle body;

[0047] Image acquisition module 20, which is magnetically connected to the magnetic levitation track, is used to acquire at least one local image of a preset spatial area during the movement along the magnetic levitation track;

[0048] The control module 30 is communicatively connected to the image acquisition module and is used to acquire each of the local images from the image acquisition module and generate a three-dimensional spatial image of the preset spatial region based on each of the local images.

[0049] In this embodiment, the image acquisition system includes at least a magnetic levitation track, an image acquisition module, and a control module, and may also include wiring, a voice module, etc. The image acquisition system can employ either repulsive or attractive magnetic levitation. Repulsive magnetic levitation typically involves electromagnets on both the image acquisition module and the magnetic levitation track, utilizing the principle of like poles repulsion to achieve magnetic levitation at zero speed and in motion. In the case of superconducting magnetic levitation, a superconducting magnet can be placed on either the image acquisition module or the magnetic levitation track to generate a strong magnetic field, while a closed coil made of conductive material is placed on the other to generate an induced magnetic field. The two magnetic fields are in opposite directions, generating a repulsive force to levitate the image acquisition module. Attractive magnetic levitation typically involves electromagnets on the image acquisition module and a magnetic levitation track made of electromagnets or ferromagnetic materials. Adjusting the electromagnetic attraction of the levitation and guide electromagnets at the bottom of the image acquisition module creates a magnetic reaction with the windings on both sides of the magnetic levitation track, levitating the train. Under the reaction of the guide electromagnets at the bottom of the image acquisition module and the magnets of the magnetic levitation track, the image acquisition module maintains a certain lateral distance from the magnetic levitation track, achieving contactless support and guidance in both horizontal and vertical directions.

[0050] At least a portion of the magnetic levitation track is made of electromagnets or ferromagnetic materials. In one feasible embodiment, at least a portion of the magnetic levitation track is a closed coil made of conductive material. When alternating current is passed through the closed coil, the closed coil becomes an electromagnet, generating a magnetic field. The magnetic levitation track is fixedly installed on the vehicle body. In one feasible embodiment, the magnetic levitation track can be installed on the surface of the vehicle body near the passenger compartment. In this case, the image acquisition module magnetically levied on the magnetic levitation track can acquire images of the interior space of the vehicle, such as images of occupants or cargo. In another feasible embodiment, the magnetic levitation track can be installed on the surface of the vehicle body away from the passenger compartment. In this case, the image acquisition module magnetically levied on the magnetic levitation track can acquire images of the exterior space of the vehicle, such as images of obstacles outside the vehicle.

[0051] In one feasible approach, the magnetic levitation track may be equipped with a stopping point. When the image acquisition module is stationary rather than in motion, for example, when the image acquisition system is in a turned-off or standby state, the image acquisition module can remain at the stopping point. This can prevent the image acquisition module from falling due to collisions or vibrations.

[0052] The image acquisition module refers to a module capable of image acquisition. The image acquisition module includes at least an image acquisition device, and may also include a connection structure, a support module, etc. The image acquisition device, used for image acquisition, can be a camera, etc. In one feasible embodiment, the image acquisition device can be a wide-angle camera or a fisheye camera. Wide-angle cameras or fisheye cameras have a wider field of view, allowing for the acquisition of a larger range of image information in a single shot, thereby improving the comprehensiveness of image acquisition. At least a portion of the image acquisition module is equipped with an electromagnet, enabling the image acquisition module to be magnetically connected to the magnetic levitation track. When alternating current is applied to the closed coils in the magnetic levitation track, the alternating current flowing in the closed coils located on both sides of the magnetic levitation track can transform the closed coils into electromagnets. The interaction between these electromagnets and the image acquisition module controls whether the image acquisition module is stationary or in motion. The image acquisition module runs along the magnetic levitation track. During operation, it can acquire at least one local image through the image acquisition device. By adjusting the image acquisition time and position, it can acquire one or more local images of a preset spatial area. The preset spatial area can be determined according to the actual image acquisition requirements. It can be adjusted by adjusting the length and position of the magnetic levitation track, and also by adjusting the acquisition parameters of the image acquisition device, such as magnification, focal length, and viewing angle.

[0053] In one feasible embodiment, the magnetic levitation track is a segmental magnetic levitation track, in which case the image acquisition module can reciprocate on the magnetic levitation track under the action of alternating current; in another feasible embodiment, referring to... Figure 2 The magnetic levitation track 10 is a circular magnetic levitation track, which is set on the vehicle body 200. In this case, the image acquisition module 20 can move clockwise or counterclockwise along the magnetic levitation track under the action of alternating current.

[0054] Optionally, refer to Figure 3 The image acquisition module 20 includes:

[0055] The support module 21 is magnetically connected to the magnetic levitation track 10;

[0056] Image acquisition device 22 is rotatably connected to the support module 21.

[0057] In this embodiment, the image acquisition module 20 includes a support module 21 and an image acquisition device 22. The support module 21 contains an electromagnet for magnetic connection with the magnetic levitation track 10. The image acquisition device 22 is mechanically connected to the support module 21 via a rotating connector. This connector allows the image acquisition device to rotate two-dimensionally in a plane or three-dimensionally in space. It can also be connected to the support module 21 via magnetic or electromagnetic forces, depending on the specific circumstances; this embodiment does not impose any limitations. The image acquisition device can change its shooting angle by rotating, improving the comprehensiveness of image acquisition. In one feasible embodiment, when the magnetic levitation track is positioned on the X-axis-Y-axis plane, if the image acquisition device can rotate in the Z-axis direction, combined with the operation of the image acquisition device on the magnetic levitation track and its rotation, comprehensive three-dimensional spatial monitoring can be achieved.

[0058] Optionally, refer to Figure 3 The image acquisition device 22 is connected to the support module 21 via at least two telescopic rods 23. The image acquisition device 22 rotates by the extension and retraction of each telescopic rod 23.

[0059] In this embodiment, the rotating connector can be at least two telescopic rods 23. When there are two telescopic rods 23, the image acquisition device 22 can rotate in the plane direction where the two telescopic rods are located by the extension and retraction of the two telescopic rods 23. When there are more than two telescopic rods 23, the image acquisition device 22 can rotate in three dimensions by the extension and retraction of each telescopic rod 23, thereby improving the comprehensiveness of image acquisition.

[0060] The control module refers to the module that controls various functional modules in the image acquisition system. The control module can be an image acquisition control device, an image acquisition control terminal device, or a server. This embodiment uses an image acquisition control device as an example. This device can be integrated into terminal devices such as vehicles with data processing capabilities, vehicle controllers, vehicle terminals, smartphones, and tablets. The control module can communicate with at least the image acquisition module and also with other functional modules in the image acquisition system, such as the magnetic levitation track, to control various functional modules in the image acquisition system. During the vehicle's power-on operation and while the image acquisition module is moving at high speed along the magnetic levitation track, the control module can control the image acquisition module to perform one or more image acquisitions of a preset spatial area, obtaining at least one local image. This allows the acquisition of various local images. A pre-trained deep learning model can be used to stitch these local images into a three-dimensional spatial image of the preset spatial area. The control module can also control the magnitude of the alternating current flowing through the magnetic levitation track, thereby controlling the operating speed of the image acquisition module. Finally, the control module can send the three-dimensional spatial image to an image display device for output display.

[0061] In this embodiment, the image acquisition system is applied to a vehicle and includes: a magnetic levitation track fixedly mounted on the vehicle body; an image acquisition module magnetically connected to the magnetic levitation track, used to acquire at least one local image of a preset spatial region during movement along the magnetic levitation track; and a control module communicatively connected to the image acquisition module, used to acquire each of the local images from the image acquisition module and generate a three-dimensional spatial image of the preset spatial region based on each of the local images. Magnetic levitation enables the image acquisition module to operate at high speed on a magnetic levitation track. Therefore, it is only necessary to arrange the magnetic levitation track on the vehicle body corresponding to the preset spatial area where image acquisition is required. The image acquisition module can then operate along the track to acquire images of the preset spatial area. Since the image acquisition module can operate at high speed on the magnetic levitation track, even if the preset spatial area is large, such as including the entire outer perimeter of the vehicle body or the entire interior of the carriage, one or more images of a large area can be acquired in a very short time. At least one of the acquired images can then be stitched together to form a three-dimensional spatial image of the preset spatial area, enabling relatively comprehensive monitoring of a large area of ​​the preset spatial area through a single camera. Even if there are obstructions in some areas, the image acquisition module can acquire images of the preset spatial area from multiple angles as it operates along the track. If part of the field of view is obstructed at a certain angle, the field of view can be supplemented from other angles. This overcomes the technical shortcomings of increasing image acquisition equipment costs as vehicle functions increase, requiring more camera configurations and wiring designs for each camera during the vehicle design phase, resulting in high design costs, and the limited flexibility of fixed-position cameras for image acquisition. It saves on equipment and design costs for vehicle monitoring and improves the flexibility of image acquisition.

[0062] Example 2

[0063] Furthermore, referring to Figure 4 Based on the above embodiments of this application, in the second embodiment of this application, the same or similar content as the above embodiments can be referred to the above description, and will not be repeated hereafter. Furthermore, this application also provides an image acquisition method, which is applied to the image acquisition system described above, and includes the following steps:

[0064] Step S10: During the movement along the magnetic levitation track, the image acquisition module acquires at least one local image of a preset spatial area.

[0065] The execution subject of the method in this embodiment is the control module as described above. The control module can be an image acquisition control device, an image acquisition control terminal device, or a server. This embodiment takes an image acquisition control device as an example. The image acquisition control device can be integrated into terminal devices such as vehicles with data processing functions, vehicle controllers, vehicle terminals, smartphones, and tablets.

[0066] In this embodiment, it should be noted that the preset spatial area refers to the area where image acquisition is required. This area can be determined based on the magnetic levitation track or in conjunction with user operation commands. For example, based on the magnetic levitation track, the area where image acquisition can be performed includes the entire area of ​​the vehicle's front, rear, left, right, and roof. When reversing, the user needs to confirm whether there are obstacles behind the vehicle. They can issue commands such as clicking on the area behind the vehicle or clicking the reversing image button to obtain a reversing image. Based on these reversing image acquisition commands, the area corresponding to the reversing action can be defined as the preset spatial area. In this way, only the image acquisition module needs to acquire images of the area corresponding to the reversing action, improving image acquisition speed, reducing computational load, and saving resources. When acquiring images of a large spatial area, it is often difficult to capture information about the entire area in a single image. This is due to the limited shooting angle of the image acquisition device and the potential for obstructions. Therefore, as the image acquisition device moves along the magnetic levitation track, it can be controlled to perform multiple image acquisitions at preset times, positions, or rotation angles to obtain multiple partial images from different perspectives. The acquisition time or position of these partial images should meet the imaging requirements of the three-dimensional spatial image. The preset position refers to the location of the image acquisition module on the magnetic levitation track, and the preset rotation angle refers to the rotation angle of the image acquisition device. This enables three-dimensional spatial image acquisition and improves the comprehensiveness of the image acquisition.

[0067] For example, during the operation of the vehicle after power-on, while the image acquisition module is moving at high speed along the magnetic levitation track, the image acquisition module is controlled to acquire images of a preset spatial area once or multiple times to obtain at least one local image.

[0068] In one feasible embodiment, the image acquisition module includes: a carrier module magnetically connected to the magnetic levitation track; and an image acquisition device rotatably connected to the carrier module. The step of acquiring at least one partial image of a preset spatial area via the image acquisition module during movement along the magnetic levitation track includes: during the vehicle's power-on operation, while the carrier module drives the image acquisition device to move at high speed along the magnetic levitation track and the image acquisition device itself rotates, controlling the image acquisition device to perform multiple image acquisitions of the preset spatial area from multiple angles to obtain multiple partial images.

[0069] Optionally, before the step of acquiring at least one local image of a preset spatial region via the image acquisition module during movement along the magnetic levitation track, the method further includes:

[0070] Step A10: In response to the voice command to activate the image acquisition system, the image acquisition system is activated so that the image acquisition module moves at high speed along the magnetic levitation track;

[0071] And / or, after the step of activating the image acquisition system, the method further includes:

[0072] Step A20: In response to the voice command to shut down the image acquisition system, the image acquisition system is shut down.

[0073] In this embodiment, it should be noted that the image acquisition system can be enabled and / or disabled via voice commands. For drivers who drive with both hands, voice control eliminates the need to use both hands when they need to access monitoring image information, making it more convenient.

[0074] For example, before the step of acquiring at least one local image of a preset spatial area by means of the image acquisition module moving along the magnetic levitation track, a voice command can be received. After receiving the voice command to activate the image acquisition system, the image acquisition system is activated so that the image acquisition module moves at high speed along the magnetic levitation track, thereby acquiring at least one local image of the preset spatial area during the high-speed movement.

[0075] For example, after the image acquisition system is enabled, a voice command can be received, and after receiving a voice command to disable the image acquisition system, the image acquisition system can be disabled.

[0076] Optionally, the step of activating the image acquisition system in response to a voice command to activate the image acquisition system includes:

[0077] Step A11: Perform performance testing on the image acquisition system, wherein the performance testing includes at least one of magnetic levitation performance testing, image acquisition device rotation performance testing, and image acquisition performance testing;

[0078] Step A12: If the performance test passes, the image acquisition system is activated in response to the voice command to activate the image acquisition system.

[0079] In this embodiment, it should be noted that before activating the image acquisition system, a performance test can be performed on the image acquisition system. This performance test includes at least one of the following: magnetic levitation performance test, image acquisition device rotation performance test, and image acquisition performance test. The magnetic levitation performance test refers to testing whether the magnetic field generated after the magnetic levitation track is energized can allow the image acquisition module to levitate normally. The image acquisition device rotation performance test refers to testing whether the image acquisition device can rotate in a preset direction. The image acquisition performance test refers to testing the image acquisition function of the image acquisition module.

[0080] For example, after the vehicle is powered on, the image acquisition system can be tested for performance. If the performance test is passed, a voice command can be received. After receiving the voice command to enable the image acquisition system, the image acquisition system is enabled. If the performance test fails, a fault message can be output to remind the user to check and repair the fault in a timely manner.

[0081] In one feasible approach, if the performance test passes, the image acquisition system can be put into a standby state before receiving a voice command. The operation of the image acquisition system in the standby state can be determined according to the actual situation, and this embodiment does not impose any restrictions on this.

[0082] Step S20: Based on each of the local images, generate a three-dimensional spatial image of the preset spatial region.

[0083] For example, the local images can be stitched together into a three-dimensional spatial image of a preset spatial region using a pre-trained deep learning model. The deep learning model is similar to existing technologies and will not be described in detail here.

[0084] In one feasible approach, after the step of generating a stereoscopic spatial image of the preset spatial region based on each of the local images, the method may further include: sending the stereoscopic spatial image to at least one vehicle function module, so that each of the vehicle function modules can perform corresponding vehicle functions based on the stereoscopic spatial image, wherein the vehicle function module includes at least one of a fatigue driving detection module, an image display module, a reversing module, etc.

[0085] Optionally, the image acquisition system further includes an image display device, and after the step of generating a stereoscopic spatial image of the preset spatial region based on each of the local images, it further includes:

[0086] Step S30: The three-dimensional spatial image is output and displayed through the image display device.

[0087] In this embodiment, for example, the stereoscopic spatial image can also be sent to an image display device for the image display device to output and display the stereoscopic spatial image, so that the user can view the stereoscopic spatial graphic through the image display device. The image display device can be a display device on a vehicle terminal, mobile phone, tablet computer, smartwatch, computer, etc.

[0088] Optionally, after the step of outputting and displaying the stereoscopic spatial image through the image display device, the method further includes:

[0089] Step S40: In response to the stereoscopic spatial image operation command, perform image transformation processing on the stereoscopic spatial image to obtain a region image, wherein the image transformation processing includes scaling processing and rotation processing;

[0090] Step S50: The image of the area is output and displayed through the image display device.

[0091] In this embodiment, for example, after the stereoscopic spatial image is output and displayed, the user can scale or adjust the angle of the output stereoscopic spatial image according to their own needs. In response to the stereoscopic spatial image operation command generated by the user's operation based on the stereoscopic spatial image, the stereoscopic spatial image is subjected to image transformation processing to obtain a region image. The image transformation processing includes scaling processing and rotation processing. Then, the transformed region image is output and displayed through the image display device.

[0092] The image acquisition method provided by this invention, applied to the image acquisition system described above, solves the technical problem of high cost in conventional vehicle monitoring technology. Compared with the prior art, the beneficial effects of the image acquisition method provided by this invention are the same as those of the image acquisition system provided by the above embodiments, and other technical features in this image acquisition method are the same as those disclosed in the image acquisition system of the above embodiments, and will not be repeated here.
