The invention discloses an express parcel real-time detection and identification algorithm based on depth information matching RGB, and the algorithm comprises the following steps: a, a depth camera collects a depth image and an RGB image of an express parcel, and carries out the alignment processing of the RGB image and the depth image; b, screening the depth map according to a depth threshold value, and only reserving an effective target in the depth map; c, effective targets in the screened depth map are processed through binaryzation, and a Mask map only about express items is obtained; d, detecting a target contour of the Mask graph, and calculating a contour moment to obtain coordinates of each target pixel; and e, obtaining the rough position of the target by using the target pixel coordinate obtained by the depth map, processing by using the target pixel coordinate and the RGB map to obtain the rough ROI region of each target, and generating each target ROI map.
