Positioning method and image capturing device thereof

A positioning method includes the steps of: capturing a positioning image by an image capturing device, determining a pixel coordinate of an object in the positioning image, and determining a global positioning system coordinate of the object according to the pixel coordinates and a transformation matrix. An image capturing device includes a camera configured to capture a positioning image, a storage medium storing with a transformation matrix, and a processor electrically connected to the camera and the storage medium respectively. The processor is configured to determine a pixel coordinate of an object in the positioning image and determine a global positioning system coordinate associated with the object according to the pixel coordinate and the transformation matrix. 本发明公开了种定位方法，包括下列步骤：以影像撷取装置撷取定位影像。判断该定位影像中物体于该定位影像的像素坐标。依据该像素坐标与转换矩阵，判断该物体的全球定位系统坐标。种影像撷取装置，包括：摄相机，用以撷取定位影像。储存媒介，储存有转换矩阵。处理器，分别电性连接该摄相机与该储存媒介，用以判断该定位影像中的待定位物的第像素坐标，并依据该第像素坐标与该转换矩阵，产生关于该待定位物的全球定位系统坐标。
