Embodiment 1

[0023] Such as figure 1 Shown is a flowchart of an image registration method provided by an embodiment of the present invention, and the method includes the following steps:

[0024] In step S101, an image to be registered and a reference image are acquired.

[0025] In the embodiment of the present invention, the apparatus for image registration first acquires the image to be registered and a reference image as a reference.

[0026] In step S102, perform morphological processing on the image to be registered and the reference image, divide the image to be registered into multiple sub-images to be registered with the same size, and divide the reference image into multiple sub-images of the same size the same reference subimage.

[0027] In the embodiment of the present invention, after the image to be registered and the reference image are acquired, morphological processing is performed on the image to be registered and the reference image, and the image to be registered is ...

Embodiment 2

[0056] Such as figure 2 Shown is the structural diagram of the image registration system provided by the embodiment of the present invention. For the convenience of description, only the parts related to the embodiment of the present invention are shown, including:

[0057] The image acquiring unit 201 is configured to acquire an image to be registered and a reference image.

[0058] In the embodiment of the present invention, the image acquisition unit 201 first acquires the image to be registered and a reference image as a reference.

[0059] A morphology processing unit 202, configured to perform morphological processing on the image to be registered and the reference image acquired by the image acquisition unit 201, divide the image to be registered into a plurality of sub-images to be registered with the same size, and divide The reference image is divided into multiple reference sub-images of the same size.

[0060] In the embodiment of the present invention, after ac...

Abstract

The invention applies to the image processing field, and provides a method and a system for image registration. The method for the image registration includes steps: obtaining an image to be registered and a reference image; performing morphological processing on the image to be registered and the reference image, dividing the image to be registered into a plurality of sub-images to be registered, of the same size, and dividing the reference image into a plurality of reference sub-images of the same size; confirming an initial reference sub-image from the reference sub-images, setting a reference template according to the initial reference sub-image, registering the reference template with the sub-images to be registered, and obtaining initial offset according to a registration result; registering the sub-images to be registered according to the initial offset, and confirming whether an initial sub-image to be registered, after being registered, includes local offset through a bisection method; registering the image to be registered according to the initial offset and/ or the local offset. The method and the system for the image registration can rapidly, and simply and conveniently register the image to be registered.

Description

technical field [0001] The invention belongs to the field of image processing, in particular to an image registration method and system. Background technique [0002] Carry out line scan of the same vehicle passing through the same collection point in two different time periods, and register the line scan image to ensure the important and critical part of vehicle driving safety. Vehicle images may have foreign objects such as oil spots, water stains, missing bolts, and graffiti. Due to the variable size of foreign objects, it is difficult to extract the features of foreign objects, so the requirements for image registration accuracy are relatively high. The line scan camera determines the scanning frequency by the instantaneous speed of the moving car, and there is no distortion in the width direction of the image, but the length of the moving car is long and the speed is not constant in a short period of time, so due to the mismatch between the speed and the scanning freque...
