System and method for determining a 3D coordinate of a moving target are provided. The system may obtain 2D detection data of the moving target generated by a 2D detection device including two detection assemblies that are mounted at a known height above a horizontal plane along a first axis that forms a tilting angle with the horizontal plane. The system may determine a 2D coordinate of the moving target in a first coordinate system including the first axis and a second axis that is perpendicular to the first axis based on the 2D detection data. The 2D coordinate of the moving target may include a first value of the first axis and a second value of the second axis. The system may determine the 3D coordinate of the moving target in a second coordinate system based on the 2D coordinate, the tilting angle, and the known height.

Radar systems and methods using the same

A system for video surveillance includes an image sensor configured capture an image including a reference zone and a memory device that stores instructions. The system also includes one or more processors that are configured to execute the instructions to determine 3D coordinates of a target comprised in the image and determine 3D coordinates of the reference zone. The one or more processors are further configured to identify an event according to the 3D coordinates of the target and the 3D coordinates of the reference zone.

Methods and systems for video surveillance

A system and method for binocular stereo vision is disclosed. The method includes acquiring a pair of images including a first image and a second image, the pair of images being captured by one or more cameras; obtaining a training model; determining a plurality of feature images according to the first image; determining one or more features of an object in the first image according to the training model and the plurality of feature images; determining a first area in the first image, the first area including at least one of the determined one or more features; obtaining depth information of the determined first area based on the first and second images; and determining a second area in the first image based on the determined first area and depth information, the second area including at least one of the determined first area.
