The invention relates to a cross-sensor object attribute analysis method and a cross-sensor object attribute analysis system, and the method is applied to a space provided with a plurality of image sensors, so that the image sensors cooperatively detect at least one subject matter. The method comprises the following steps: the image sensors transmit original data or attribute vector data of multiple frames of images sensed by the image sensors to a main information processing device, wherein the original data and each attribute vector correspond to a time record; the main information processing device generates at least one attribute vector according to the original data of each frame of image, and each attribute vector corresponds to one subject matter; or the at least one attribute vector provided by the information processing units corresponds to the at least one subject matter.
