Embodiment Construction

[0058] Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. Where the following description refers to the drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the illustrative examples below are not intended to represent all implementations consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with some aspects of the invention as recited in the appended claims.

[0059] At the customs land gate, it is necessary to inspect the underside of large trucks to prevent criminals from hiding prohibited or smuggled goods through the underside of the vehicle.

[0060] The current vehicle inspection method is as follows: using a line scan camera with a magnetic induction coil device, when a metal object is sensed, it indicates that a vehicle has passed, and the line scan...

Abstract

An image processing method, device, device and system provided by the present invention includes: after detecting a target, acquiring a current frame depth image including the target collected by a TOF lens; according to the current frame depth image and the previous frame depth image The depth image determines the moving distance of the target within the time interval when two frames of depth images are taken, cuts the visible light image from the corresponding visible light image according to the moving distance, and splices the visible light images corresponding to each adjacent two frames of depth images in sequence to obtain a moving distance of the target. Obtaining the image corresponding to the target can realize cutting the visible light picture according to the moving distance of the target. When the target moves fast, the moving distance is longer, and more visible light pictures are cut; when the target moves slowly, the moving distance is shorter. , cutting less visible light pictures, so that the effect of the image after splicing is not affected by the moving speed of the target, and has the advantage of high efficiency.

Description

technical field [0001] The present invention relates to the technical field of image processing, and in particular, to an image processing method, apparatus, device and system. Background technique [0002] In the customs land transportation gate, due to the large space under the vehicle of the large truck, criminals often pass through the customs by hiding the underside of the vehicle, or hide prohibited or smuggled goods through the underside of the vehicle. In order to maintain social stability and people's safety, it is very important to inspect the underbody of vehicles entering and leaving customs. [0003] Due to the small height of the car chassis from the ground, it is difficult to inspect. The usual inspection method is: use a line scan camera with a magnetic induction coil device. When a metal object is sensed, start the camera and continuously collect line scan images, then stitch all the images together to obtain the bottom image of the vehicle. The above meth...
