Embodiment Construction

[0049] In a preferred example of the present invention, this embodiment adopts such as figure 1 The above-mentioned automatic counting equipment for online bar profile images uses Windows operating system as the upper computer, and uses GDI in the VC++6.0 compilation environment to process bar profile images. The driver program of the image acquisition card used is compatible with VC++6.0, which is more conducive to the direct call of the function and improves the production efficiency.

[0050] First, when the bar profile is placed on the counting table, the CCD camera moves laterally once and collects the image data of the bar profile, and the image acquisition card stores the image data in the folder with automatic sensing function in the host computer, and the recognition program is started through the command Immediately afterwards, the image file is perceived and opened for the next step of recognition processing.

[0051]The working flow chart of the automatic counting...

Abstract

The invention relates to an Online bar section image automatic counting device and method. The invention relates to the digital image processing and applying technologies. The image counting device of the invention includes an upper computer, an image collection card, a CCD camera and a lighting equipment; wherein the upper computer is connected with the image collection card; and the image collection card is respectively connected with the CCD camera and the lighting equipment. The image counting method of the invention includes the steps of sensing and opening the image, pre-processing the image, processing edge detection operators, converting 2D distances, searching and counting seed points as well as displaying the counting result. After adopting the gray level image threshold segmentation and pseudocolor coding technologies, the invention not only can process gray images on the end surface of the bar section, but also can process blue or yellow images on the end surface of the bar section; the system adaptation is wider; the invention discloses a method for obtaining the perimeter, area and number of the bar sections in the image; the counting precision of the seed searching method is relatively higher, which can count partial bar sections with irregular end surface shapes and different shooting sizes.

Description

technical field [0001] The invention relates to digital image processing and application technology, in particular to an online bar profile image automatic counting device and method. Background technique [0002] The quantitative packaging of bars and profiles in steel mills is still at a relatively low level. The counting of rods and profiles is carried out manually. This work is mechanically monotonous. The staff is highly stressed for a long time, and it is easy to cause trance and fatigue. The manual counting results are greatly affected by human factors, and errors are inevitable, which brings troubles to product sales. To free the counting personnel from the long-term boring work, it is the actual need of the steel mill to develop a counting and packaging system with a high degree of automation. [0003] The original production line counted rods and profiles with a manipulator in the form of a sprocket, but it was difficult to separate small-diameter rods and profile...
