    • The image counting method includes the steps of: acquiring 3D images from the region by a 3D camera, wherein the 3D images include a plurality of pixels, and the pixels have x, y and z coordinate values and pixel data; mapping the x, y and z coordinate values and the pixel data of the pixels into a plurality of correlative coordinate values of a spatial correlative coordinate represented as (x, z, t), wherein t is the number of pixels whose pixel data are lower than a threshold in y direction with the same x and z coordinate values; grouping the correlative coordinate values into a plurality of groups according to a correlation between each of the correlative coordinate values in x-z plane; and comparing the correlative coordinate values of each of groups with the correlative coordinate values of the 3D images of the specific objects to determine the number of specific objects in the region.
    • 图像计数方法包括以下步骤:通过3D照相机从该区域获取3D图像,其中3D图像包括多个像素,并且像素具有x,y和z坐标值和像素数据; 将x,y和z坐标值和像素的像素数据映射为表示为(x,z,t)的空间相关坐标的多个相关坐标值,其中t是像素数据较低的像素数 在y方向上具有相同的x和z坐标值的阈值; 根据x-z平面中的每个相关坐标值之间的相关性,将相关坐标值分组成多个组; 以及将每个组的相关坐标值与特定对象的3D图像的相关坐标值进行比较,以确定该区域中的特定对象的数量。
