Embodiment Construction

[0021] see figure 1 , is a flow chart of a repairing method for image deformation provided in this application. Such as figure 1 As shown, the method includes:

[0022] 101. Acquire a line-scan camera image of the measured object.

[0023] The line scan camera image is the image of the measured object captured by the line scan camera. The tested object can be metal, plastic, paper and fiber, and the type of the tested object is not limited in the embodiment of the present application.

[0024] 102. Calculate the deformation factor of the line scan camera image.

[0025] The deformation factor refers to the degree of deformation between the original physical size of the measured object and the size of the imaged object. The original physical size of the measured object, including the horizontal width and vertical width, can be measured by the length measurement tool. The size of the imaged object is calculated from the width of the field of view of the line array camera, ...

Abstract

The application discloses a method and a device for repairing image deformation, which relate to the technical field of image processing and are used to solve the problem that the measurement result of a detection application is inaccurate due to image deformation. The method mainly includes the following steps: acquiring a linear array camera image of a detected object; calculating the deformation factor of the linear array camera image; determining whether the linear array camera image is deformed according to the deformation factor; and if the linear array camera image is deformed, correcting the linear array camera image according to the deformation factor. The method and the device are mainly used in the repair process of a deformed linear array camera image.

Description

technical field [0001] The present application relates to the technical field of image processing, and in particular to a method and device for repairing image deformation. Background technique [0002] Line scan cameras are commonly used to inspect continuous materials such as metals, plastics, paper and fibers, to name a few. The detected object usually moves at a constant speed, and one or more cameras are used to continuously scan it line by line to achieve uniform detection of its entire surface. It can process the image line by line, or process the area array image composed of multiple lines. In addition, line scan cameras are very suitable for measurement applications, thanks to the high resolution of the sensor, it can measure accurately down to the micron. [0003] The line-scan camera adopts a line-scan image sensor, which collects one line at a time, and the captured image is in the shape of a "line" with a length of several k. To stitch several lines into one i...
