It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are, for example, capable of operation in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
The embodiment of the present invention provides a data transfer method, which does not switch the resolution of an acquired planar image mainly in the process of switching a data transfer mode, and specifically, as shown in fig. 1, a data transfer system may implement data transfer according to the following steps:
receiving a switching request of a data transfer mode, wherein the switching request is used for requesting to switch a first data transfer mode into a second data transfer mode; acquiring a color image of the user according to the current first resolution and acquiring a depth image of the user according to the second resolution according to the switching request; sampling the color image so that the resolution of the sampled color image is consistent with the second resolution; and carrying out face detection on the user according to the depth image and the sampled color image so as to complete data transfer.
In the switching process of data transfer, the resolution of the acquired image is not switched, and the down-sampling is performed after the color image of the user is acquired, so that the time for resetting the resolution in the switching process is reduced, the time consumed for switching the data transfer mode is also reduced, the waiting time of the user is reduced, and the user experience is improved.
The embodiment of the present invention provides a data transfer method, which is mainly a method executed by a data transfer system, where the data transfer system in this embodiment includes an image acquisition device, and a flowchart is shown in fig. 2, and includes:
It can be understood that a user may operate the data transfer system to initiate a switching request to the data transfer system, which is mainly used to switch the current first data transfer mode to the second data transfer mode, where the resolution required by the image capture device in the data transfer system in the first data transfer mode is higher, such as a code scanning payment mode, and the resolution required by the image capture device in the data transfer system in the second data transfer mode is lower, such as a face brushing payment mode.
And step 102, acquiring a color image of the user according to the current first resolution and acquiring a depth image of the user according to the second resolution according to the switching request.
Because the resolution required by the image acquisition device is higher in the first data transfer mode, and the depth image does not need to be acquired, the image acquisition device only acquires the plane image according to the first resolution in the first data transfer mode, and the first resolution is higher.
The image acquisition device in the data transfer system can comprise a first sensor for acquiring a planar color image and a second sensor for acquiring a depth image, wherein in the embodiment, the first sensor acquires the color image of a user according to a first resolution; and the second sensor acquires the infrared image of the user according to the second resolution, so that the depth image can be obtained according to the infrared image. The second resolution is lower than the first resolution, and the depth image can describe the actual depth from each pixel point in the color image acquired by the first sensor to the plane.
And 103, sampling the color image to ensure that the resolution of the sampled color image is consistent with the second resolution.
Specifically, the data transfer system can sample the color image with the first resolution ratio according to a preset sampling strategy to obtain the color image with the second resolution ratio, and thus, each pixel point in the sampled color image can find the corresponding pixel point in the depth image, so that each pixel point has depth information. Since a color image with a low resolution is obtained by sampling, this is called down-sampling.
The sampling strategy is pre-stored in the data transfer system, and specifically in the presetting process, a first position of a first pixel point of a first row in the depth image acquired from the second sensor in the color image acquired by the first sensor, such as coordinate information (x1, y1), may be determined first; and determining a second position of a last pixel point of a last line in the depth image in the color image, such as (x2, y 2); and determining the scaling of horizontal scaling and vertical scaling of the color image according to the difference value between the second position and the first position, and storing a sampling strategy, wherein the sampling strategy comprises the scaling.
The scaling of the horizontal scaling may be a ratio of a difference between the abscissa in the second position and the abscissa in the first position to a certain constant C, i.e., (x2-x1)/C, and the scaling of the vertical scaling may be a ratio of a difference between the ordinate in the second position and the ordinate in the first position to another constant D, i.e., (y2-y1)/D, wherein the second resolution of the depth image is a certain constant multiplied by another constant, i.e., cxd.
It should be noted that, when the data transfer system is shipped from the factory, the acquisition policy may be preset in the data transfer system, and the first sensor and the second sensor respectively acquire the color image and the infrared image under the condition that the positions of the camera and the reference surface are kept unchanged, which may be different from the color image and the depth image obtained in step 102. For example, fig. 3a shows a color image taken by a first sensor, while fig. 3b shows an infrared image taken by a second sensor.
And step 104, carrying out face detection on the user according to the depth image and the sampled color image so as to complete data transfer.
Specifically, the data transfer system performs face recognition according to the depth image and the sampled color image to obtain feature information of a user face, and matches the feature information with preset face feature information, if the feature information is not matched with the preset face feature information, face detection is unsuccessful, and the user is prompted that the face detection is unsuccessful; if the matching is successful, the face detection is successful, and the data transfer can be continued.
It should be noted that, in one case, the method of the embodiment of the present invention may be applied to a data transfer system as shown in fig. 4a, an image acquisition device in the system may specifically include a camera control end, a first sensor (sensor) for acquiring a color image, and a second sensor for acquiring an infrared image, and the data transfer system may further include an application layer control end, an application layer, and the like. In this case, the color image is sampled by the application layer, wherein:
the camera control end configures the first sensor and the second sensor through an Image Signal Processor (ISP), for example, configures the resolution of the sensor when acquiring an Image and when the sensor starts to acquire an Image.
When the current data transfer mode is the first data transfer mode, the camera control end configures the first sensor to acquire an image according to the first resolution through the ISP, and after the application layer receives the switching request of the data transfer mode, the camera control end starts the second sensor through the ISP and acquires the image according to the second resolution. The first sensor and the second sensor respectively collect color images and infrared images of a user and send the color images and the infrared images to the application layer through the ISP, the control end of the application layer can control the application layer to sample the color images to obtain color images with a second resolution, then depth images of the user are obtained according to the infrared images, and face detection and data transfer are completed by combining the sampled color images.
In another case, the method of the embodiment of the present invention may also be applied to a data transfer system as shown in fig. 4b, where an image acquisition device in the system may specifically include an integration of a camera control end and an ISP, a first sensor (sensor) for acquiring a color image, and a second sensor for acquiring an infrared image, and the data transfer system may further include an application layer control end and an application layer, in which case, the image acquisition device samples the color image, where:
the integration of the camera control end and the ISP configures the camera configuration of the first sensor and the second sensor, such as the resolution of the sensor when acquiring images and when the sensor starts to acquire images.
When the current data transfer mode is the first data transfer mode, the integration of the camera control end and the ISP configures the first sensor to acquire an image according to the first resolution, and after the application layer receives a switching request of the data transfer mode, the integration of the camera control end and the ISP starts the second sensor and acquires the image according to the second resolution. The first sensor and the second sensor respectively acquire a color image and an infrared image of the user and transmit the color image and the infrared image to the integration of the camera control end and the ISP, the integration of the camera control end and the ISP samples the color image of the user to obtain a color image with a second resolution, and the color image and the infrared image are transmitted to the application layer; the application layer control end can control the application layer to obtain a depth image of the user according to the infrared image, and the face detection and data transfer are completed by combining the sampled color image.
As can be seen, in the method of this embodiment, when the switching of the data transfer mode is received, the current first resolution is not switched, but the color image of the user is collected according to the current first resolution and the depth image of the user is obtained according to the second resolution, and the color image is downsampled, so that the resolution of the sampled color image is consistent with the second resolution, and then the face detection of the user is performed according to the depth image and the sampled color image, so as to complete the data transfer. In the switching process of data transfer, the resolution of the acquired image is not switched, and the down-sampling is performed after the color image of the user is acquired, so that the time for resetting the resolution in the switching process is reduced, the time consumed for switching the data transfer mode is also reduced, the waiting time of the user is reduced, and the user experience is improved.
The data transfer method according to the embodiment of the present invention is specifically described as a payment method, where the data transfer system is mainly a scanning terminal of a merchant, and the scanning terminal is specifically applied to the system shown in fig. 4a, the first data transfer mode is code scanning payment, and the second data transfer mode is face brushing payment. Specifically, as shown in fig. 5, the method of the present embodiment includes:
step 201, the scanning terminal is currently in a code scanning payment state, the application layer displays a code scanning payment interface, and if the scanning terminal needs to be switched to a face brushing payment state, a user clicks a switching control, so that the user can select face brushing payment information.
When the scanning terminal is in a code scanning payment state, the camera control end configures the first sensor to acquire an image according to the first resolution through the ISP, and the second sensor cannot be started.
In step 202, the application layer of the scanning terminal receives a request for switching the payment mode, and the user requests to switch the code scanning payment mode to the face payment mode.
And step 204, after the application layer receives the color image and the infrared image of the user, the control end of the application layer controls the application layer to sample the color image to obtain a color image with a second resolution, further obtains a depth image of the user according to the infrared image, and completes face detection and face payment by combining the sampled color image.
As can be seen, in this embodiment, for a camera architecture in which the resolution cannot be adjusted by software inside the camera, a color image with high resolution (i.e., the first resolution) is used during code scanning payment; when brushing face payment, the color image with the same low resolution (namely the second resolution) as the depth image is realized through the sampling process, so that the user can obtain good code scanning experience when scanning code payment, and the color image with the same resolution as the depth image is used when brushing face payment, so that the face brushing payment is completed, the user experience is ensured, and seamless switching is realized.
