Method and device for collecting linear array Bayer-to-area array Bayer format image

Abstract

The invention relates to a method for collecting an image in a linear array Bayer-to-area array Bayer format. The method comprises the following steps: firstly, collecting a to-be-output image corresponding to the linear array Bayer format; extracting points from a to-be-output image corresponding to the linear array Bayer format according to a first preset rule or a second preset rule; then determining a to-be-output image corresponding to the area array Bayer format according to a point extraction result; and finally, outputting a to-be-output image corresponding to the area array Bayer format. The invention further relates to a device for collecting the image in the format of converting the linear array Bayer into the area array Bayer. The invention also relates to a two-line color linear array camera which comprises the device for collecting the image in the format of converting the linear array Bayer into the area array Bayer. According to the invention, the to-be-output image corresponding to the linear array Bayer format is converted into the to-be-output image corresponding to the area array Bayer format through the point extraction mode, so that the two-line color line-scan digital camera can quickly achieve the purposes of improving the line frequency and reducing the data volume without image compression.

Description

technical field [0001] The invention relates to the technical field of line array cameras, in particular to an image acquisition method and device of an area array Bayer format. Background technique [0002] A line scan camera is a camera that uses a line sensor. Through the relative movement of the subject and the line scan camera, the continuous acquisition of the subject is realized, and then several rows of line images are spliced ​​into a complete surface image for output. It is usually used in the detection field where the measured field of view is slender, requires a large field of view or extremely high precision. [0003] A two-line color line scan camera is a typical line scan camera, and its three-color component sensors are distributed on two sensor lines, that is, as figure 1 The color sensor distribution diagram of a two-line color line scan camera is shown. In the figure, the sensors of the G color (green) component are distributed along one line, and the sen...

Problems solved by technology

However, when compressing a linear array Bayer format image, it is necessary to convert the linear array Bayer format image into an image in RGB format (each pixel has three color components of R, G, and B) through difference processing before compression can be performed. , this compression method is not only troublesome, but also easily leads to the loss of image information
