Claim 19:
20. A non-transitory computer readable medium storing instructions, the instructions, when executed by at least one processor, causing the at least one processor to implement a method comprising:
generating two-dimensional (2D) detection data of the moving target by a two-dimensional (2D) detection device, wherein the 2D detection device is mounted on a perimeter that is substantially perpendicular to a horizontal plane and the 2D detection device including a shell and at least two detection assemblies, wherein the shell is used to accommodate the at least two detection assemblies; and the at least two detection assemblies are mounted at a known height above the horizontal plane with a tilting angle, wherein the at least two detection assemblies are mounted at a known height above the horizontal plane with a tilting angle includes:
the at least two detection assemblies are mounted parallel to the shell of the 2D detection device and the shell of the 2D detection device is mounted with the tilting angle to the horizontal plane; or

the at least two detection assemblies are mounted with the tilting angle to the shell of the 2D detection device and the shell of the 2D detection device is mounted parallel to the horizontal plane;
obtaining two-dimensional (2D) detection data of the moving target from the two-dimensional (2D) detection device;
determining a 2D coordinate of the moving target in a first coordinate system based on the 2D detection data, wherein the first coordinate system is a 2D coordinate system including the first axis and a second axis that is perpendicular to the first axis, and the 2D coordinate of the moving target includes a first value of the first axis and a second value of the second axis; and
determining the 3D coordinate of the moving target in a second coordinate system based on the 2D coordinate, the tilting angle, and the known height.
