Abstract

An exemplary security monitoring method includes first obtaining an image of a monitoring place captured by a camera, the image comprising distance information between the camera and captured objects, then extracting the distance information from the obtained image, next comparing the distance information of the obtained image with that of a pre-stored object model to determine whether the obtained image matches the pre-stored object model; and lastly determining that there is object(s) removed from or remained in the monitoring place when the obtained image does not match the pre-stored object module, and generating a prompt message to prompt user that there is object(s) removed from or remained in the monitoring place.

Claims

1. A security monitoring system comprising:

an image obtaining module to obtain an image of a monitoring place captured by a camera, the image comprising distance information between the camera and captured objects;

an object detecting module to extract the distance information from the obtained image;

an image analysis module to compare the distance information of the obtained image with that of a pre-stored object model to determine whether the obtained image matches the pre-stored object model; and

an executing module to determine that there is object(s) removed from or remained in the monitoring place when the obtained image does not match the pre-stored object module, and generate a prompt message to prompt user that there is object(s) removed from or remained in the monitoring place.

2. The security monitoring system as described in claim 1, wherein the image analysis module compares the distance information of each of the pixels of the captured object(s) in the obtained image with that of corresponding pixels in the object model, determines a ratio of the number of pixels of the captured object(s) in the obtained image whose distance information is the same as that of the corresponding pixels in the object(s) model to the number of the corresponding pixels in the object model, and determines that the obtained image matches the object model if the determined ratio is greater than or equal to a preset value.

3. The security monitoring system as described in claim 1, further comprising a person detecting module, wherein the person detecting module compares image data of the obtained image with character data of each of 3D person models when the obtained image does not match the object model, and determines that there is no person in the monitoring place when the image data in the monitoring place does not match the character data of any of the 3D person models, the executing module determines that there is object(s) removed from or remained in the monitoring place when there is no person in the monitoring place.

4. The security monitoring system as described in claim 1, further comprising an area setting module, wherein the area setting module obtains a map of the monitoring place from the storage system in response to the user operation, obtains the image of one place from the map in response to the user operation, and determines the monitoring place as a range of the place to be monitored in response to user selections.

5. The security monitoring system as described in claim 4, wherein the user selections comprise a first selection, a second selection, a third selection, a fourth selection, and a fifth selection, the first selection is an operation to select a single object in the image, the second selection is a series of operations to select two or more objects in the image, the third selection is a series of operations to select an object which is subtracted a second object from a first object in the image, the fourth selection is a series of operations to select an object which is an overlapping part between a first object and a second object in the image, and the fifth selection is a series of operations to select objects which is subtracted an overlapping part from a first object and a second object in the image.

6. A security monitoring method comprising:

obtaining an image of a monitoring place captured by a camera, the image comprising distance information between the camera and captured objects;

extracting the distance information from the obtained image;

comparing the distance information of the obtained image with that of a pre-stored object model to determine whether the obtained image matches the pre-stored object model; and

determining that there is object(s) removed from or remained in the monitoring place when the obtained image does not match the pre-stored object module, and generating a prompt message to prompt user that there is object(s) removed from or remained in the monitoring place.

7. The security monitoring method as described in claim 6, wherein the comparing step further comprises:

comparing the distance information of each of the pixels of the captured object(s) in the obtained image with that of the corresponding pixels in the object model;

determining a ratio of the number of the pixels of the captured object(s) in the obtained image whose distance information is the same as that of the corresponding pixels in the object model to the number of the corresponding pixels in the object model; and

determining that the obtained image matches the object model if the determined ratio is greater than or equal to a preset value.

8. The security monitoring method as described in claim 6, wherein the security monitoring method further comprises:

comparing image data of the obtained image with character data of each of 3D person models when the obtained image does not match the object model, and determining that there is no person in the monitoring place when the image data in the monitoring place does not match the character data of any of the 3D person models; and

determining that there is object(s) removed from or remained in the monitoring place when there is no person in the monitoring place.

9. The security monitoring method as described in claim 6, wherein the security monitoring method further comprises:

obtaining a map from the storage system in response to the user operation;

obtaining the image of one place from the map in response to the user operation; and

determining the monitoring place as a range of the place to be monitored in response to user selections.
