Detailed Description
In the prior art, image display is performed according to the speed of image acquisition, and each time a frame is acquired, the frame is transmitted to a display end, and the display end displays the latest transmitted image. However, since the image display speed depends on the image acquisition speed, when the image acquisition is too fast, the display speed is fast, and the occupation degree of computing resources is high; when the image acquisition is too slow, the blocking appears in the display, and the look and feel and judgment are affected. In order to overcome the technical problems, the application provides an image display method which can display real-time images according to preset image display frequency and improve the smoothness of image display.
The embodiment of the application discloses an image display method, referring to fig. 1, the method may include the following steps:
step S11: and acquiring original image data acquired by an image data acquisition end in real time through a first thread, and placing the original image data into the bottom of a first queue.
In this embodiment, the image data acquisition end is first detected continuously by the first thread, and each image data acquired by the acquisition end is put into the bottom of the first queue. The first queue may adopt a sequential storage structure, and a first-in first-out image storage and reading mode, for example, as shown in fig. 2, the first thread stores the original image data acquired from the image data acquisition end each time at the bottom of the first queue.
Step S12: and acquiring the first image data at the top of the first queue in real time through a second thread, and placing the first image data at the bottom of the second queue.
In this embodiment, the top of the first queue is continuously detected by the second thread, and when the top of the first queue has image data, the image data at the top at this time, i.e. the first image data, is stored at the bottom of the second queue; the second queue can adopt a sequential storage structure, adopts a first-in first-out image storage and reading mode, and stores the first image data acquired each time at the bottom of the second queue; for example, as shown in fig. 2, the first image data acquired by the second thread from the top of the first queue is deposited to the bottom of the second queue. It can be understood that the first queue and the second queue belong to two threads, the operation of each other is not affected, and the first queue only needs to concentrate on matching with the image data acquisition end, so that each image data acquired by the acquisition end can be ensured to be stored.
In this embodiment, after the acquiring, by the second thread, the first image data at the top of the first queue in real time, the method may further include: and deleting the first image data from the first queue through the first thread. After the second thread puts the first image data contained at the top of the first queue into the second queue, the top of the first queue deletes the first image data, and when the first queue is in a sequential storage structure, the rest image data in the first queue sequentially moves forward.
In this embodiment, the image display method may further include: and setting the first queue and the second queue as circulating queues according to the memory condition of the equipment. It can be understood that if the memory resources of the device to which the above image display method is applied are smaller, the first queue and the second queue may be set to be circular queues when designing the queues, so as to prevent storage from crossing the boundary.
In this embodiment, the acquiring, by the second thread, the first image data at the top of the first queue in real time may include: acquiring first image data from the top of the first queue through the second thread according to the configuration of a preset thread lock; wherein the thread lock is a thread lock that performs dequeuing operations of the first queue for the first thread and the second thread performs operations of acquiring first image data of a top of the first queue. It is understood that the thread lock is a thread lock that performs a dequeuing operation of the first queue for the first thread, and the second thread performs an operation of acquiring the first image data of the top of the first queue. That is, the thread lock technique is employed when the first image data at the top of the first queue is deposited at the bottom of the second queue, thereby avoiding the impact on the first queue.
Step S13: and detecting the second queue through a display end according to a preset display frequency, and selecting target image data from the second queue according to the ordering of the image data in the second queue for display.
In this embodiment, the display end detects the second queue according to a preset display frequency, and reads the target image data from the second queue according to the ordering of the image data in the second queue for display. It can be understood that by setting the display frequency, the display end may select the image data from the second queue according to the display frequency to display, and may select the target image data from several image data recently enqueued according to the ordering of the image data in the second queue, for example, the second queue is in a first-in first-out storage and reading manner, if 100 image data are sequentially arranged in the queue, the 98 th, 99 th or 100 th image data may be selected as the target image data to display. Therefore, the image display speed in the embodiment can be inconsistent with the image acquisition speed, and the image display of the display end meets the comfort of looking.
In this embodiment, after selecting the target image data from the second queue for displaying according to the ordering of the image data in the second queue, the method may further include: and deleting the target image data and the image data sequenced before the target image data from the second queue through the second thread. It can be understood that after the display end reads the target image data in the second queue, the second queue deletes the target image data and the image data in front of the target image data in the queue according to the ordering of the target image data in the second queue, that is, deletes the image data enqueued before the enqueuing of the target image data, so as to prevent the internal boundary crossing.
In this embodiment, the selecting the target image data from the second queue for displaying may include: performing image data processing on the target image data to obtain corresponding target image frames, and playing the target image frames through a display screen of the display end; wherein the image data processing includes any one or more of coordinate conversion, color conversion, image registration, and data reconstruction. It will be appreciated that the collected raw image data often needs to be processed to be an image for display, and the processing time of these intermediate processes also makes the display and the collection speed different, which affects the smoothness of the display. Thus, in this embodiment, image data processing is performed on the image data in the second queue, where the image data processing includes any one or more of coordinate conversion, color conversion, image registration, and data reconstruction. It can be understood that the second queue is only required to be operated in cooperation with the setting of the display frequency and the data processing of the image, and the first queue only needs to be focused on cooperation with the image data acquisition end, so that each acquired image data is ensured to be stored.
From the above, the original image data acquired by the image data acquisition end is acquired in real time through the first thread, and the original image data is put into the bottom of the first queue; acquiring first image data at the top of the first queue in real time through a second thread, and placing the first image data at the bottom of the second queue; the display end detects the second queue according to the preset display frequency, and selects target image data from the second queue to display according to the ordering of the image data in the second queue, namely the display end can read the image data from the second queue according to the preset display frequency to display. Therefore, the acquired images are processed in a double-queue and multi-thread mode, so that support is provided for flexible image display, the image display is independent of the image acquisition speed, and the smoothness of the display is ensured.
The embodiment of the application discloses a specific image display method, referring to fig. 3, the method may include the following steps:
step S21: the method comprises the steps of acquiring original image data and corresponding time stamps acquired by an image acquisition end in real time through a first thread, and placing the original image data and the corresponding time stamps into the bottom of a first queue.
In this embodiment, the original image data acquired by the image acquisition end is acquired in real time through the first thread, and meanwhile, a timestamp corresponding to the original image data is acquired, and the acquired original image data and the corresponding timestamp are placed at the bottom of the first queue.
Step S22: and acquiring the first image data and the corresponding time stamp at the top of the first queue in real time through a second thread, and placing the first image data and the corresponding time stamp at the bottom of the second queue.
In this embodiment, the first image data and the corresponding time stamp at the top of the first queue are obtained in real time through the second thread, and the obtained first image data and the corresponding time stamp are placed at the bottom of the second queue.
Step S23: and detecting the second queue through the display terminal according to a preset display frequency, and selecting image data closest to the current time according to the time stamp to display.
In this embodiment, the display end detects the second queue according to the preset display frequency, and selects the image data closest to the current time as the target image according to the timestamp of the image data in the second queue, and plays the target image data. It can be understood that, for example, when the set image display frequency is smaller than the acquisition speed of the image data acquisition end, the image throwing speed of the second queue is relatively slower, and the second queue becomes longer, so that the display end can select, according to the timestamp information, the image data closest to the current time as the target image data to display, and then, the second queue throws the useless data, that is, the image data before the target image data, appropriately according to the timestamp, so as to prevent the memory from being out of range.
In this embodiment, the selecting the target image data from the second queue for displaying may include: and if the display end detects that the second queue is empty, backtracking and playing the acquired last frame of target image. It can be understood that when the set image display frequency is greater than the acquisition speed of the image data acquisition end, the second queue throws out the image fast, and when the second queue is empty, the display end can retrospectively display the last frame of target image frame, thereby ensuring that the display is not blocked.
In this embodiment, after selecting the target image data from the second queue for display according to the timestamp corresponding to the image data in the second queue, the method may further include: according to the timestamp corresponding to the target image data, image data with acquisition time smaller than the timestamp are screened out from the second queue to serve as image data to be deleted; and deleting the target image data and the image data to be deleted from the second queue through the second thread. It can be understood that after the display end reads the target image data in the second queue, the second queue throws out the target image data and the image data before the target image data according to the timestamp of the image data, so as to prevent the internal boundary crossing.
From the above, in this embodiment, the original image data and the corresponding timestamp acquired by the image acquisition end are acquired in real time through the first thread, the original image data and the corresponding timestamp are placed at the bottom of the first queue, then the first image data and the corresponding timestamp at the top of the first queue are acquired in real time through the second thread, the first image data and the corresponding timestamp are placed at the bottom of the second queue, finally the second queue is detected through the display end according to the preset display frequency, and the image data closest to the current time is selected according to the timestamp for display. The time stamp corresponding to the image data is obtained while the original image data is obtained, then the image data closest to the current time is selected according to the time stamp for display, so that the playing of the real-time image under the preset display frequency can be ensured, the dependence of the image display on the image acquisition speed is solved, the frequency of the image display can be set according to the requirement, the display of the real-time image can be carried out according to the preset image display frequency, the smoothness of the display is ensured, and the flexible processing of the image display is realized.
