These disclosures relate to a method for detecting and removing personnel interference while measuring volume of an object. An image of an object is obtained, a background information of the image is removed, and the image is converted into a binary image. An outline of the object is detected from the binary image. A determination is made whether the outline extends towards a boundary of the field of view. If the outline of the object does not extend to the boundary of the field of view, the volume of the object is measured. Otherwise, an extending part is removed from the outline using a morphological method, if removable. If the extending part is removed, the volume of the object is measured based on an outline of the object obtained after the extended part is removed, and a class 1 warning is issued. Otherwise, a class 2 warning is issued and the measurement is ended. This approach improves efficiency of the object volume measurement.
