Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Fig. 1 is a flowchart of a target information storage method according to an embodiment of the present invention. The target information storage method provided by the embodiment of the application can be applied to the situation of storing the information of the target detected in the image. Typically, the embodiments of the present application are applicable to the case of caching the target information. The method may be specifically executed by a target information storage apparatus, which may be implemented by software and/or hardware, and may be integrated in an electronic device capable of implementing the target information storage method. Referring to fig. 1, the method of the embodiment of the present application specifically includes:
and S110, determining a target image of a detection target in the low-compression format original image, and determining a detection quality score of the target image.
The low-compression format original image may be an image obtained by encoding an image or a video frame image acquired by an image acquirer based on a low-compression method, such as a YUV image. If the resolution of the image collector is 4MP, the size of a frame of YUV image is about 6M. The target detection is carried out on the low-compression format original image, so that the target image can be detected more accurately. The detection target is an image obtained by performing target detection on the original image in the low-compression format.
In the embodiment of the application, target detection is performed on one frame of the obtained low-compression format original image, detection targets in the low-compression format original image are locked, and a corresponding target image in the low-compression format original image is determined for each detection target. And performing quality analysis on the target image of the detection target, and determining the detection quality score of the target image.
And S120, if the detection quality score is the highest quality score of the detection target, extracting a low-compression format target image of the detection target from the low-compression format original image, converting the low-compression format target image into a high-compression format target image, and converting the low-compression format original image into a high-compression format original image.
For example, if the image quality of the target image of the detection target determined in the currently acquired low-compression format original image is the highest, the target image is more valuable for business processing, and the target image needs to be stored. However, if the original image in the low compression format is directly stored or the target image in the low compression format is stored, a large memory is occupied and storage resources are wasted. For example, a frame of YUV image has a size of about 6M, and storing 40 frames of YUV images requires 240M memory, which consumes a large storage space. In the embodiment of the application, if the detection quality score of the target image is the highest quality score of the image of the detection target, and according to the position of the detection target appearing in the low-compression format original image, the low-compression format target image of the detection target is extracted from the low-compression format original image, the low-compression format target image is converted into the high-compression format target image, and the low-compression format original image is converted into the high-compression format original image, so that the memory occupied during storage is reduced. The high compression format may be a lossy compression format, such as JPEG, PNG, and the like. The image collected by the image collector with the resolution of 4MP is converted into a JPEG format, the size of the image is 800K under the condition of high image quality, and the occupied memory amount is greatly reduced compared with the size of a YUV image of 6M.
S130, determining target information of the detection target, and storing the target information and the high-compression format original image in a storage area, wherein the target information comprises the detection quality score and the high-compression format target image.
The storage may be in a form of cache, or may also be in a form of memory. In the embodiment of the application, the score value corresponding to the highest quality score and the high-compression format target image are used as the target information of the detection target, and the target information and the high-compression format original image are stored in the storage area, so that the storage of the high-quality image of the detection target is realized, and the occupied memory is reduced. And releasing the low-compression format original image after the target information is stored.
In the embodiment of the application, no matter how many targets are detected from the low-compression-format original image, when the detection quality score of the target image of the detection target in the low-compression-format original image is the highest quality score of the detection target and the low-compression-format original image needs to be stored, the low-compression-format original image is converted into the high-compression-format original image, only one high-compression-format original image needs to be stored, and repeated storage is not needed, so that the storage space of the storage area is saved.
In the embodiment of the application, a target image of a detection target in an original image in a low-compression format is determined, and a detection quality score of the target image is determined; if the detection quality score is the highest quality score of the detection target, extracting a low-compression format target image of the detection target from the low-compression format original image, converting the low-compression format target image into a high-compression format target image, and converting the low-compression format original image into a high-compression format original image; and determining target information of the detection target, and storing the target information and the high-compression format original image in a storage area, wherein the target information comprises the detection quality score and the high-compression format target image, so that the storage of the high-quality target image is realized, and the storage space is saved through format conversion.
In the embodiment of the present application, the target information further includes a target identifier; the process of determining whether the detection quality score is the highest quality score of the detection target comprises: matching the target identification of the detection target with the target identification of the storage target in the storage area; the storage target is a detection target which is stored in the storage area; and if the matching is not successful, determining the detection quality score as the highest quality score of the detection target.
For each target there is a unique target identification. The target identification of the detection target detected in the low-compression format original image is matched with the target identification of the target stored in the storage area. And if the target identification of the non-storage target is matched with the target identification of the detection target, determining the detection target as a new target. And if the target identification of the storage target is matched with the target identification of the detection target, determining that the detection target does not appear in the image acquired by the image acquisition device for the first time and has been detected before. In an original image in a low compression format, there may be a plurality of target images of detection targets, some of which may appear for the first time, some of which may not appear for the first time, or all of which may not appear for the first time. If all the detection targets in the low-compression format original image appear for the first time, all the detection targets are processed according to S120, and the high-compression format target images corresponding to all the detection targets are stored, and because all the low-compression format target images are extracted from the same low-compression format original image, the image frame numbers of the high-compression format original images to which all the high-compression format target images belong are the same, only one high-compression format original image is stored, and the high-compression format original image is associated with all the high-compression format target images according to the image frame numbers, so that the storage space is saved, and repeated storage is avoided.
Specifically, if the target identifier of the storage target does not match the target identifier of the detection target in the storage area, the detection target is determined to be a new target, the detection quality score of the target image of the detection target is the highest quality score of the detection target, and the target information of the detection target and the high-compression format original image need to be stored in the storage area, that is, the target identifier of the detection target, the detection quality score of the target image, the high-compression format target image and the high-compression format original image are stored in the storage area. The detection target stored in the storage area becomes a storage target.
In an embodiment of the present application, the determining whether the detection quality score is the highest quality score of the detection target further includes: if the target identification of the storage target and the target identification of the detection target are successfully matched in the storage area, determining that the storage target and the detection target are the same target; comparing the detection quality score of the target image of the detection target with the storage quality score of the storage target in the storage area; if the detection quality score is higher than the storage quality score corresponding to the storage target, determining that the detection quality score is the highest quality score of the detection target; and if the detection quality score is lower than or equal to the storage quality score corresponding to the storage target, ending the processing operation on the target image of the detection target. If the detection quality score is higher than the storage quality score corresponding to the storage target, determining target information of the detection target, and storing the target information and the high-compression format original image in a storage area, wherein the method comprises the following steps: and replacing the target information of the storage target in the storage area with the target information of the detection target.
For example, if the matching between the target identifier of the storage target and the target identifier of the detection target in the storage area is successful, it is determined that the detection target is not a new target and has been detected in the image captured by the image capture device before, and therefore, it is necessary to determine whether the detection quality score of the target image of the detection target is the highest quality score relative to the storage quality score corresponding to the storage target in the storage area. And if the detection quality score is higher than the storage quality score corresponding to the storage target, determining the detection quality score as the highest quality score of the detection target, and replacing the target information of the detection target with the target information of the storage target in the storage area, so that the image with the highest detection target quality is stored in the storage area. And if the detection quality score is lower than or equal to the storage quality score corresponding to the storage target, determining that the image quality of the target image of the detection target is not the highest, so that the target information of the detection target does not need to be stored, the target information corresponding to the storage target is still stored, the processing operation on the detection target is ended, and the processing on the next detection target is continued.
The scheme has the advantages that the target information of the detected target can be comprehensively stored through the matching of the target identification, and the repeated storage can be avoided. In addition, through comparison of image quality scores, the images stored in the storage area are guaranteed to be the images with the highest target quality, and therefore the method has higher value for business processing.
Fig. 2 is a flowchart of a target information storage method according to another embodiment of the present invention. For further optimization of the embodiments, details which are not described in detail in the embodiments of the present application are described in the embodiments. Referring to fig. 2, a target information storage method provided in an embodiment of the present application may include:
s210, determining a target image of a detection target in the low-compression format original image, and determining a detection quality score of the target image.
And S220, if the detection quality score is the highest quality score of the detection target, extracting a low-compression format target image of the detection target from the low-compression format original image, converting the low-compression format target image into a high-compression format target image, and converting the low-compression format original image into a high-compression format original image.
And S230, determining target information of the detection target, and storing the target information and the high-compression format original image in a storage area, wherein the target information comprises the detection quality score, the high-compression format target image and a detection count value of the detection target.
Determining target information of the detection target, including: clearing the detection count value of the detection target; and if the detection target is not detected continuously, accumulating the detection count value according to a preset time interval.
For example, when a detection target is identified in the low-compression format original image, the detection count value of the detection target is cleared. During the subsequent detection, the detection count value is accumulated according to a preset time interval, for example, one increase per second. If the detection target is identified, clearing the detection count value corresponding to the detection target, and if the target is not detected, continuously accumulating the detection count value.
S240, if the detection count value is larger than the preset detection count value, moving the target information of the detection target out of the storage area.
The preset detection count value may be set according to actual conditions, for example, to 10. If the detection count value is increased by one every second, when the detection count value reaches 10, the detection target is not detected within 10 seconds, namely the detection target is not in the acquisition range of the image acquisition device for 10 seconds. If the detection count value is larger than the preset detection count value, the detection target cannot be detected in the original image in the low-compression format, and the detection target does not appear in the acquisition range of the image acquirer continuously. Therefore, the target information of the detection target can be moved out of the storage area to save the space of the storage area. Target information of the detection target may be sent to a server or the like for service processing.
In the embodiment of the application, when the detection count value is detected to be greater than the preset detection count value and the target information of the detection target is moved out of the storage area, the moved target information is the target identifier, the detection count value, the detection quality score and the high-compression format target image of the detection target, and the high-compression format original image is not moved out.
And S250, determining whether the image frame number of the high-compression-format original image in the storage area still exists in the target information of the storage target in the storage area.
In this embodiment of the present application, the target information further includes an image frame number of the original image in the high compression format to which the target image in the high compression format belongs. Illustratively, whether or not the image frame number of the original image in the high-compression format stored in the storage area is still present in the object information of the storage object in the storage area is detected in real time. If the high-compression format target image exists, the high-compression format target image which is extracted from the high-compression format original image corresponding to the image frame number is determined to exist in the storage area, and therefore other processing is not carried out.
And S260, if the high-compression format original image does not exist, removing the high-compression format original image from the storage area.
For example, if the image frame number of the high-compression format original image stored in the storage area does not exist in the object information of the storage object in the storage area, it is determined that all the high-compression format object images extracted from the high-compression format original image corresponding to the frame number have been shifted out, and the high-compression format original image corresponding to the frame number also has no effect, so that the high-compression format original image corresponding to the frame number is shifted out from the storage area and released, thereby realizing timely cleaning of useless images in the storage area, and effectively saving the storage space of the storage area.
The scheme of the embodiment of the application. When the detection target is determined to be no longer present in the acquisition range of the image acquisition device through the detection count value, the target information of the detection target is deleted from the storage area in time, and when the image frame number of the high-compression format original image stored in the storage area is detected and does not exist in the target information of the storage target in the storage area, the high-compression format original image corresponding to the frame number is removed from the storage area in time, so that the situation that the image of the target which is no longer present occupies the memory of the storage area is avoided, and the storage space of the storage area is effectively saved.
