摘要： A method of acquiring feature information of a detected object is provided, including: controlling the detected object to pass through a detection apparatus; controlling an imaging system to perform radiation scanning on the detected object acquiring a radiation scanning image of the detected object acquiring feature information of the detected object through the radiation scanning image. The detected object includes a first part, a detection part and a second part sequentially in a first direction. The acquiring feature information of the detected object through the radiation scanning image includes: acquiring a first boundary line between the detection part and the first part and a second boundary line between the detection part and the second part through the radiation scanning image; and calculating a dimension between the first boundary line and the second boundary line in the first direction to acquire a dimension of the detection part in the first direction.
