Problems solved by technology

[0004] For this reason, the technical problem to be solved by the present invention is that the monitoring camera uses the thumbnail preview technology to compress pictures and needs to occupy more CPU, which is easy to cause the system to run slowly or be paralyzed. The embedded system of the monitoring camera usually uses a self-defined storage system. The identifiable file path cannot use the virtual path of the Webserver to map the actual file path, and thus cannot realize the loading of thumbnails, so a method and system for image processing and image preview are proposed

Embodiment 1

[0087] This embodiment provides a method for image processing. In this embodiment, a picture taken by a surveillance camera is taken as an example, such as figure 1 shown, including the following steps:

[0088] The server side obtains the original picture, and compresses the copy picture of the original picture into a thumbnail for storage. The original picture obtained is a picture captured by a surveillance camera. The server end may be a processor of a monitoring camera.

[0089] The server side receives the query original picture request sent by the client side. The client may be a web server.

[0090] The server side copies the thumbnail corresponding to the original picture to the thumbnail virtual path, and sends the original picture query response and the thumbnail virtual path to the client for the client to select the original picture to be previewed / downloaded.

[0091] The server receives the original image preview / download request sent by the client.

[0092...

Embodiment 2

[0116] This embodiment provides a method for previewing pictures, such as Figure 5 shown, including the following steps:

[0117] Send a request to query the original image to the server.

[0118] Receive the query original picture response and thumbnail virtual path sent by the server, and select the original picture to be previewed / downloaded.

[0119] Send the original image preview / download request to the server.

[0120] Receive the original picture preview / download response sent by the server and the virtual path of the original picture, and select preview / download.

[0121] In the surveillance camera, after the client sends a picture request, it will receive the query original picture response and the thumbnail virtual path sent by the server, and then display the thumbnail preview of the surveillance camera on the web browser.

[0122] In the surveillance camera, the client selects the original picture to be previewed / downloaded, and can click on the corresponding ...

Embodiment 3

[0125] This embodiment provides a system for image processing, such as Figure 6 shown, including:

[0126] The preprocessing module is used to obtain the original picture, and compress the copy picture of the original picture into a thumbnail for storage.

[0127] The first receiving module is configured to receive a query original picture request sent by the client.

[0128] The first processing module and the first sending module, the first processing module is used to copy the thumbnail corresponding to the original picture to the thumbnail virtual path, and the first sending module is used to send the original picture query response and the thumbnail virtual path to Client, for the client to select the original picture to be previewed / downloaded.

[0129] The second receiving module is configured to receive the original picture preview / download request sent by the client.

[0130] The second processing module and the second sending module, the second processing module ...

Abstract

The invention provides an image processing and previewing method and system. For the request for inquiring an original image, a thumbnail corresponding to the original image is copied to a thumbnail virtual route, and the thumbnail virtual route is sent to a client side; for the request for previewing / downloading of the original image, the original image needing to be previewed / downloaded by the client side is copied to an original image virtual route, and the original image virtual route is sent to the client side; unrecognizable image files in a monitoring video are mapped to a virtual route in a virtual memory disk mode so that the client side can preview thumbnails instantly, a user selects the original image needing to be loaded, the time is saved for the user, and the user experience is improved. The thumbnails obtained through compression are saved temporarily in a buffer queue, and when a CPU is idle, the thumbnails are saved in a storage device in sequence; in this way, the occupied CPU can be reduced, and the situation that a system operates slowly or breaks down is avoided.

Description

technical field [0001] The invention relates to the technical field of computer information processing, in particular to a method and system for image processing and image preview. Background technique [0002] Surveillance cameras are quasi-cameras used in security. Its pixels and resolution are higher than those of computer video heads, but lower than those of professional digital cameras or DVs. Surveillance cameras are mostly single video capture devices, and rarely have data storage functions. Surveillance cameras are mainly divided into gun type, hemispherical, and high-speed dome in terms of appearance. In addition, there are analog monitoring and IP network monitoring, which are widely used in many security fields such as banking, transportation, and safe cities. [0003] The capture function of surveillance cameras is often used. In the existing technology, when users search for captured pictures, they often only see the picture item information. They need to click...
