Embodiment Construction

[0037] see image 3 As shown, it is a circuit block diagram of an image processing device 100 described in the embodiment of the present invention, which is used to execute the image processing method of the present invention for locating and extracting the barcode area in the image. The method and the image processing device 100 executing the method are suitable for performing image processing on a static sampled image, so as to capture the barcode area where the barcode is located, so as to identify the barcode information of each barcode. The image processing device 100 may be a handheld computing device, such as a personal digital assistant (PDA, Personal Digital Assistant), a mobile navigation device (PND, Portable Navigation Device) or a smart phone (Smart Phone). However, the image processing device 100 is not limited to a handheld computing device, and may also be a desktop computer or a notebook computer.

Abstract

The invention discloses an image processing method for positioning and capturing a bar code region in an image, and the method is suitable for an image processing device. The method comprises: defining a plurality of sampling lines in a sampling image, and finding sections in which the bar code possibly exists along each sampling line by the image processing device; and if the image processing device is on two adjacent sampling lines, and the found section in which the bar code possibly exists is positioned approximately at the position of a transverse shaft, judging that a quadrilateral region exists between the sections, in which the bar code exists, of two adjacent sampling lines. Therefore, the image processing device can position and capture the bar code region in the image quickly.

Description

technical field [0001] The present invention relates to an image processing method, in particular to an image processing method for locating and extracting several barcode regions from an image. Background technique [0002] By installing barcode recognition software, a general data processing device can also sample and recognize a barcode to be recognized through a built-in or external camera lens, so as to obtain barcode information. [0003] refer to figure 1 Shown is a sample image 1 including a barcode. The identification method adopted by the current barcode identification software is to define a horizontal line 2 in the center of the sampled image 1, so that the horizontal line passes through the long blocks forming the barcode. Next, the data processing device executing the barcode recognition software obtains the pixels (Pixels) on the horizontal line 2 one by one along the aforementioned horizontal line 2 . Afterwards, the data processing device calculates the g...
