Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clear and clear, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
With the increase of the application data volume of the high-definition camera equipment in multiple stages, the conventional video coding and decoding technology can not meet the requirements of mass data transmission and storage. Therefore, a more efficient video reconstruction and encoding method is needed to further compress video data to meet the increasing data transmission and storage requirements.
The invention provides a video data processing method, which can meet the transmission requirement of the existing wireless network by providing higher video coding efficiency, and can flexibly store video data to achieve the requirement that storage equipment with the same storage capacity can store longer monitoring video data.
Referring to fig. 1, fig. 1 is a flowchart of a video data processing method according to the present invention. As shown in fig. 1, the video data processing method according to the embodiment of the present invention includes the following steps:
and step S100, when the original video data is obtained, carrying out data reduction and reconstruction on the original video data to obtain the reconstructed video data with reduced data.
In particular, the invention processes the original video data at the terminal, that is, the terminal is used to reconstruct, encode the data video. The terminal can acquire the original video data shot by the video data equipment. The video data apparatus may be a high-definition image pickup apparatus or an apparatus in which video data has been stored.
In one implementation, the step S100 further includes: data reduction reconstruction rules are preset. Wherein the data reduction reconstruction rule includes removing a target frame image from the original video data.
Specifically, the invention presets the data reduction reconstruction rule, and does not directly encode and store the original video data shot by the video data equipment, removes certain frame images in the original video data, can reduce the number of frames of the video images, inevitably reduces the storage amount during storage, and is also beneficial to data transmission.
In a further implementation manner, referring to fig. 2, the step S100 specifically includes:
step S110, when the original video data is obtained, identifying the data format of the original video data, and obtaining image frame number information and coding algorithm information;
and step 120, removing the target frame image in the original video data according to the image frame number information and the data reduction reconstruction rule to obtain the reconstructed video data.
Specifically, when receiving the original video data, the terminal identifies the data format of the original video data, and obtains image frame number information and coding algorithm information, so as to remove the target frame image and code the data video according to the image frame number information and the coding algorithm information.
In a further implementation manner, referring to fig. 3, the step S110 specifically includes:
step S111, when the original video data is obtained, judging whether the original video data is coded or not;
step S112, if the original video data is coded, decoding the coded original video data;
step S113, the data format of the decoded original video data is identified, and the image frame number information and the coding algorithm information are obtained.
Specifically, the original video data needs to be directly or indirectly transmitted to the terminal, and in order to improve transmission efficiency, the encoded original video data may be transmitted. In this way, when the terminal receives the original video data, firstly judging whether the original video data is coded, and if so, firstly decoding; if the coding is not performed, the data format of the original video data can be directly identified, and the image frame number information and the coding algorithm information are obtained.
In a further implementation, the target frame image includes a first target frame image and a second target frame image. Referring to fig. 4, the step S120 specifically includes:
step S121, taking a frame image which does not have a preset image mark in the frame images of the original video data as a first target frame image according to the image frame number information;
step S122, selecting a plurality of frame images with preset image identifications from the frame images of the original video data as second target frame images;
and step S123, removing the first target frame image and the second target frame image according to the data reduction reconstruction rule to obtain the reconstructed video data.
Specifically, the present invention requires selection when removing frame images from the original video data. For example, the monitoring device at a certain intersection records monitoring video data, and in the actual storage process, when no pedestrian or running vehicle passes through the intersection, the video segment is invalid and can not be stored, and at this time, the preset image identifier includes: people and running vehicles. The frame image is the first target frame image without the person and the running vehicle. In order to further reduce the original video data, the invention further selects some frame images from the frame images with preset image identifications as second target frame images for removal.
Further, referring to fig. 5, the step S122 specifically includes:
step S1221, selecting a frame image with a preset image identifier from the frame images of the original video data;
step S1222, selecting a frame image from the frame images with the preset image identifier as a second target frame image every predetermined number of frame images.
Specifically, one frame image may be selected as the second target frame image for removal every predetermined number of frame images. For example, every 10 frame images, one frame image is selected, that is, the 11 th frame image is selected for removal. Therefore, certain frame images are uniformly removed, the display effect of the original video data is not affected, the data volume is further reduced, the data transmission is facilitated, and the storage devices with the same storage capacity can store more monitoring video data. Of course, a plurality of frame images may be selected randomly from the frame images having the preset image identifier as the second target frame image.
Step S100 is followed by: and step 200, performing coding processing on the reconstructed video data to obtain target video data.
Specifically, the method carries out coding processing on the reconstructed video data, further compresses the video data, and is beneficial to data transmission and storage. Therefore, the invention reduces the original video data into the target video data, thereby meeting the requirement of the prior wireless network transmission, simultaneously flexibly storing the video data, and meeting the requirement that the storage equipment with the same storage capacity can store longer monitoring video data.
Further, the step S200 may be implemented in two ways: according to the identified coding algorithm information, adopting a coding protocol corresponding to the coding algorithm information to code the reconstructed video data to obtain target video data; or selecting a target coding protocol according to the data reduction reconstruction rule to carry out coding processing to obtain target video data.
That is, according to the previously identified encoding algorithm (decompression algorithm), encoding processing is performed on the reconstructed video data by adopting the corresponding encoding protocol, so as to obtain target video data; or selecting other coding protocols for coding according to the data reduction reconstruction rule.
In one implementation, the step S200 further includes: and sending the target video data to a network storage server and/or storage equipment.
Specifically, the target video data is transmitted to the network storage server and/or the storage device for storage, so that the network storage server and/or the storage device can store more video data.
