[0023] Embodiment 1
[0024] According to one aspect of the embodiments of the present invention, an embodiment of an image acquisition device is provided.
[0025] Figure 1 is a schematic diagram of an image acquisition device according to an embodiment of the present invention, as Figure 1 shown, the device includes:
[0026] An image acquisition device 101, configured to acquire a plurality of images of a target object according to a trigger signal.
[0027] The target object in the above structure is the object of image acquisition, and the image acquisition device 101 can be used to acquire images of the target object. The trigger signal refers to a signal used to initiate the image acquisition behavior of the target object during the image acquisition process, and the image acquisition device 101 performs image acquisition of the target object according to the trigger signal.
[0028] In an alternative embodiment, the image acquisition device 101 is configured to acquire an image of a target object after receiving a trigger signal. The acquisition method can be photography, using a camera to capture the target object, or 3D (Three-Dimensional) scanning, using a dedicated device to convert the three-dimensional shape and texture of an object into a digital model, or remote sensing, using a satellite, an aircraft, or other remote sensing devices to obtain image data of the Earth's surface, but is not limited thereto. The acquired image can be one or multiple, and the specific number depends on the requirements of the actual application scenario.
[0029] A fan 102 is used to dissipate heat from the image acquisition device.
[0030] The image acquisition device in the above structure refers to a device for acquiring image data, including but not limited to the image acquisition device 101, the fan 102, the laser generator 103, and the controller 106.
[0031] In an alternative embodiment, a large amount of heat is generated during the use of the image acquisition device. The fan 102 is used to dissipate heat from the image acquisition device, dissipate the heat generated by the image acquisition device, maintain the stability of the device operating temperature, prevent the image acquisition device from being damaged or its performance from degrading due to overheating, thereby extending the service life of the image acquisition device and ensuring the stable performance of the image acquisition device.
[0032] A laser generator 103 is configured to emit laser light towards the fan 102, so that the target component 104 of the fan 102 reflects the laser light to the photosensitive device 105, and the photosensitive device 105 is configured to generate a laser reception signal based on the laser light.
[0033] The target component 104 in the above structure refers to a component located on the fan 102 that can reflect laser light, and is used to reflect the laser light emitted by the laser generator 103 onto the photosensitive device 105. The photosensitive device 105 is a device that can sense light and generate an electrical signal, and is used to sense the laser light reflected by the target component 104 and generate a laser reception signal. The laser reception signal is a signal generated after the fan 102 rotates to a specific position and the photosensitive device 105 senses the laser light, and can be used to represent that the fan 102 has rotated to a specific position.
[0034] In an alternative embodiment, the laser generator 103 can continuously emit laser light towards the fan 102, and the target component 104 at a fixed position on the fan 102 can reflect the laser light. Therefore, when the fan 102 rotates to the same specific position, the target component 104 can reflect the laser light. The photosensitive device 105 can receive the laser light reflected by the target component 104 and generate a laser reception signal based on the received laser light. Therefore, the generation of the laser reception signal can represent that the fan 102 has rotated to a specific position.
[0035] A controller 106, configured to generate at least one periodic trigger signal based on a preset period when receiving an image acquisition instruction, generate at least one acquisition signal according to a laser reception signal, and generate a trigger signal based on the periodic trigger signal and the acquisition signal at the same moment.
[0036] The image acquisition instruction in the above structure is an instruction indicating that the image acquisition device starts to perform image acquisition. The preset period is the period for image acquisition, which can be preset according to the actual application scenario and requirements. The image acquisition device 101 performs periodic image acquisition according to the preset period. The periodic trigger signal is generated based on the preset period and is a signal indicating that the image acquisition device 101 can start the image acquisition operation at this moment. The acquisition signal is generated according to the laser reception signal and can represent the signal that the fan 102 rotates to a specific position. The trigger signal is generated based on the periodic trigger signal and the acquisition signal at the same moment, representing that the image acquisition device 101 is currently in a state where it can perform the image acquisition operation and the fan 102 has rotated to a specific position.
[0037] In an alternative embodiment, after receiving the image acquisition instruction, the image acquisition device can start to perform image acquisition. The controller 106 generates a periodic trigger signal according to the preset period. The periodic trigger signal represents that the image acquisition device 101 can currently perform the image acquisition operation. Therefore, the image acquisition device 101 receiving the periodic trigger signal is a necessary but not sufficient condition for performing the image acquisition operation. That is, when the periodic trigger signal is not received, the image acquisition device 101 cannot perform the image acquisition operation. In addition, when the image acquisition device 101 only receives the periodic trigger signal, it cannot start the image acquisition operation either. Only when the image acquisition device 101 receives both the periodic trigger signal and the acquisition signal at the same moment, can a trigger signal be generated to trigger the image acquisition operation. The acquisition signal is generated by the controller 106 according to the laser reception signal generated by the photosensitive device 105, and the generation of the laser reception signal can represent that the fan 102 has rotated to a specific position. Therefore, the generation of the trigger signal represents that the current image acquisition device 101 is at the moment when it is allowed to perform the image acquisition operation during the period, and the fan 102 has periodically rotated to a specific position.
[0038] In an embodiment of the present invention, an image acquisition device includes an image acquisition device for acquiring multiple images of a target object according to a trigger signal; a fan for dissipating heat for the image acquisition device; a laser generator for emitting laser light to the fan so that a target component of the fan reflects the laser light to a photosensitive device, and the photosensitive device is used to generate a laser receiving signal according to the laser light; a controller for generating at least one periodic trigger signal based on a preset period in the case of an image acquisition instruction, generating at least one acquisition signal according to the laser receiving signal, and generating a trigger signal based on the periodic trigger signal and the acquisition signal at the same time, and determining that the controller instructs the image acquisition device to perform image acquisition only when the fan blade rotates to a specific position and is within the trigger period, thereby achieving the purpose of ensuring that the center of gravity is at the same position each time the image is acquired, and ensuring that the acquired image will not be displaced due to position deviation, thereby achieving the technical effect of reducing the error caused by the shaking of the cooling fan, improving the acquisition accuracy of the image acquisition device, and eliminating the ghost phenomenon caused by the shaking of the image acquisition device, thereby solving the technical problem that the image acquisition device has low acquisition accuracy and ghost phenomenon appears in the image due to the shaking of the cooling fan inside the device.
[0039] Optionally, the fan 102 includes a plurality of fan blades, the target component 104 is a target blade among the plurality of fan blades, and the target blade is provided with a metal film.
[0040] The target blade in the above structure is a blade with a metal film attached to it among the multiple fan blades. The number of target blades can be one or more. The metal film can be used to reflect laser. When the laser beam irradiates the surface of the metal film, the metal film will reflect the laser and focus it to a specific area, thereby achieving the focusing and reflection of the laser.
[0041] In an optional embodiment, a fan 102 for dissipating heat for an image acquisition device has a plurality of blades, wherein a blade with a metal film attached thereto is called a target blade. Since a metal film capable of reflecting laser light is attached thereto, the target blade can reflect the laser light emitted by the laser generator 103. Furthermore, since the fan 102 rotates periodically, the reflection of laser light by the target blade is also a periodic behavior. The reflection of laser light by the target blade can indicate that the fan 102 rotates to a specific position within a cycle.
[0042] Optionally, the device further includes: an image generating device, connected to the image acquisition device 101, for generating a scanned image of the target object according to the multiple images and the acquisition sequence of the multiple images.
[0043] The image generation device in the above steps can be used to process the image data collected by the image acquisition device 101 to obtain a scanned image of the target object. The target object refers to the object to be imaged. The scanned image is a digital image file corresponding to the target object generated by the image generation device. In the application scenario of collecting two-dimensional images, the scanned image can be an image file in JPEG format, PNG format, or PDF format, but is not limited thereto. In the application scenario of collecting three-dimensional images, the scanned image can be a three-dimensional model.
[0044] In an alternative embodiment, the image generation device is connected to the image acquisition device 101. After the image acquisition device 101 acquires the target object to obtain the corresponding image data, the scanned image of the target object is generated sequentially according to the acquisition order of the image data. When the scanned image collected is a two-dimensional image, generating the scanned image based on multiple images and the acquisition order of multiple images can increase the coverage of the images, cover a larger area or capture more details by collecting multiple images; it is also possible to select clearer images from multiple images to improve the image quality, or obtain images from different angles to increase the diversity of the images. When the scanned image collected is a three-dimensional image, a three-dimensional model can be generated based on multiple images and the acquisition order of multiple images. Therefore, generating the scanned image based on multiple images and the acquisition order of multiple images can better meet the application requirements of different scenarios.
[0045] Embodiment 2
[0046] According to another aspect of the embodiments of the present invention, an embodiment of an image acquisition method is also provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in a different order than here.
[0047] It should be noted that the image acquisition method can be applied to the image acquisition device in Embodiment 1 above. The specific implementation and application scenarios of the image acquisition method are the same as those in Embodiment 1 and will not be elaborated here.
[0048] Figure 2 is a flowchart of the image acquisition method according to the embodiments of the present invention. As Figure 2 shown, the method includes:
[0049] Step S202, in response to receiving an image acquisition instruction for a target object, controlling the image acquisition device in the image acquisition device to generate at least one periodic trigger signal based on a preset period, where the image acquisition device is any one of the above image acquisition devices.
[0050] Step S204, controlling the laser generator to emit laser light to the fan, so that the target component of the fan reflects the laser light to the photosensitive device, wherein the photosensitive device is used to generate a laser receiving signal according to the laser light.
[0051] Step S206: Generate at least one acquisition signal according to the laser receiving signal.
[0052] Step S208: generating a trigger signal based on the periodic trigger signal and the acquisition signal at the same time.
[0053] Step S210: acquiring multiple images of the target object according to a trigger signal.
[0054] In an optional embodiment, the trigger signal can indicate that the image acquisition device is in a state where it can acquire images and the fan has rotated to a specific position. Therefore, based on the trigger signal, multiple images of the target object are acquired, which can ensure that the fan blades rotate to the same position each time an image is acquired, thereby ensuring that the centrifugal force generated when the fan blades rotate is uniform and can offset the shift in the center of gravity, thereby reducing errors caused by fan jitter.
[0055] Optionally, controlling the laser generator to emit laser to the fan so that the target component of the fan reflects the laser to the photosensitive device includes: controlling the laser generator to emit laser to the fan so that the target blade of the fan reflects the laser to the photosensitive device, wherein the target blade is bonded with a metal film.
[0056] Optionally, controlling the laser generator to emit laser to the fan so that the target component of the fan reflects the laser to the photosensitive device includes: in response to receiving an anti-shake mode start instruction of the image acquisition device, controlling the laser generator to emit laser to the fan so that the target blade of the fan reflects the laser to the photosensitive device.
[0057] In an optional embodiment, when the image acquisition device receives an instruction to turn on the anti-shake mode, it starts to control the laser emitter to emit laser to the fan, so that the target blades of the fan reflect the laser to the photosensitive device, so that the photosensitive device can generate a laser receiving signal and send it to the image acquisition device, so that the image acquisition device can identify the time when the fan rotates to a specific position in each rotation cycle.
[0058] Optionally, the method further includes: generating a scanned image of the target object according to the acquisition sequence of the multiple images.
