Embodiment Construction

[0050] In order to make the object, technical solution and advantages of the present invention more clear and definite, 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 here are only used to explain the present invention, not to limit the present invention.

[0051] The invention provides a processing method for video data storage, such as figure 1 As shown, the method includes:

[0052] S1. Calculate the remaining storage space for storing video data, and judge whether the calculated remaining storage space is smaller than the lower limit of the remaining storage space, and if it is smaller, perform step S2.

[0053] In order to reserve more storage space, the storage space for storing video data is first calculated, and it is judged whether the remaining storage space is less than its lower limit value, and if it is less, the step of proce...

Abstract

The present invention provides a method and a system for storing video data. The method comprises the following steps: calculating a remaining storage space for storing the video data; judging whether the calculated remaining storage space is less than a lower limit of the remaining storage space; if so, starting to traverse video frames within a first time range of storage time from the earliest storage moment; and comparing differences of two adjacent frames of images among first video frames for deleting one frame, having the difference less than a predetermined difference threshold, of the two frames of images, so as to delete similar images in the video images; and utilizing the maximum storage space to save useful video data, thereby improving the utilization ratio of the storage space for the storage of video images, and also facilitating the finding of useful image information in future.

Description

technical field [0001] The present invention relates to the technical field of data storage, in particular to a method and system for storing video data. Background technique [0002] Driving recorder is used more and more widely at present. With the high-definition requirements of users for recording video information, high-resolution image acquisition has become the mainstream acquisition system, and high-resolution images occupy a large amount of storage space. In order to store high-resolution videos, large-capacity storage devices are required , but in view of the fact that the larger the storage space, the higher the price of the storage device, so in order to collect more video information, existing products adopt a circular storage method, that is, cover older content with the latest video, but due to earlier After the video is overwritten, the information contained in it will be lost, and the effective storage time cannot meet the storage needs of users. [0003] ...
