Video monitoring system and method
View Patent ↗A method for monitoring a target area using a video monitor device that controls a video camera located at the target area to capture left images and right images of the target area. The video monitor device analyzes each of the left and right images to form a combined image, compresses all of the combined images to generate compressed images, and stores the compressed images into a storage system. When an event happened in the target area, a compressed image corresponding to the event time is obtained from the storage system. The video monitor device decompresses the compressed image to generate a 3D image of the target area, and displays the 3D image on a display device.

combining the identical image data and the different image data of the left image and the right image to form a combined image;
repeating the selecting step to the combining step, until all of the left images and the right images have been processed;
compressing all of the combined images to generate compressed images, and storing the compressed images into a storage system;
determining the time of an event that has occurred in the target area;
obtaining a compressed image corresponding to the time from the storage system;
decompressing the compressed image to generate a 3D image of the target area; and
displaying the 3D image on a display device for monitoring of the target area.
8. The method according to claim 7 , wherein the video camera is a dual-lens camera having a first lens capable of capturing the left images and a second lens capable of capturing the right images of the target area at the same time.
9. The method according to claim 8 , wherein the left images and the right images of the target area are synthesis of 3D images viewable through a 3D glasses.
10. The method according to claim 7 , wherein the 3D image displayed on the display device is viewed through a 3D glasses.
11. A non-transitory computer-readable storage medium having stored thereon instructions that, when executed by a least one processor of a monitor device, causes the monitor device to perform a video monitoring method, the method comprising:
