Abstract: The present disclosure provides a recovery device and a method for recovering a magnetic particle. The recovery device includes a main pipe, a needle tube, and a suction power mechanism. The needle tube is connected to a first end of the main pipe, and a terminal of the needle tube is magnetic for adsorbing a magnetic particle to the terminal of the needle tube. The suction power mechanism is configured to absorb the magnetic particle attached on the terminal of the needle tube into the main pipe. The present disclosure utilizes a magnetic needle tube to implement adsorption of the magnetic particle while the magnetic particle is absorbed into the main pipe by an absorption power mechanism, thus achieving recovering of the magnetic particle.

Abstract: An image processing method and system, a storage medium and a moving system are provided, and the image processing method includes: obtaining a 2D depth array Dp having depth information of a target object; calculating to obtain a depth vector D=[d1, d2, d3, . . . , di, . . . , dn], in which an element di is an average value of elements of the ith row in the 2D depth array; calculating to obtain an edge determination vector ΔD=[Δd1, Δd2, Δd3, . . . , Δdi, . . . , Δdn−1], in which an element Δdi=|di−di+1|; calculating an average value d0=(|Δd2−Δd1|+|Δd3−Δd2|+ . . . +|Δdn−1−Δdn−2|)/(n−2); and comparing an absolute value |Δdi−Δdi+1| with d0 to identify an edge of the target object, in which in a situation where |Δdi−Δdi+1| is greater than d0, it is determined that the elements of the ith row in the 2D depth array Dp correspond to the edge of the target object.
