Embodiment Construction

[0058] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with aspects of the invention as recited in the appended claims.

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

[0060] The current method of vehicle bottom inspection is: use a line-scan camera with a magnetic induction coil device. When a metal object is sensed, it indicates that a vehicle is passing by, start the...

Abstract

The invention provides an image processing method, device, equipment and system, and the method comprises the steps: obtaining a current frame depth image which is collected by a TOF lens and comprises a target after the target is detected; according to the current frame depth image and the previous frame depth image, determining a moving distance of the target in a time interval of shooting the two frames of depth images, and cutting a visible light picture from a corresponding visible light image according to the moving distance, the visible light pictures corresponding to every two adjacent frames of depth images are spliced in sequence to obtain an image corresponding to the target, the visible light pictures can be cut according to the moving distance of the target, and when the target moves fast, the moving distance is long, and more visible light pictures are cut; when the target moves slowly, the moving distance is short, and few visible light pictures are cut, so that the effect of the spliced image is not influenced by the moving speed of the target, and meanwhile, the method has the advantage of high efficiency.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image processing method, device, equipment and system. Background technique [0002] At the customs land transport gate, due to the large space under the truck, lawbreakers often pass through the customs by hiding the bottom of the truck, or hide prohibited or smuggled goods through the bottom of the truck. In order to maintain social stability and people's safety, it is very important to check the bottom of vehicles entering and leaving the customs. [0003] Due to the small height of the car chassis from the ground, it is difficult to check. 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 collect the line-scan images continuously, then stitch all the images together to obtain an image of the vehicle bottom. The above method can only ensure that the target obje...
