Problems solved by technology

When the difference method is used for positioning, the target to be positioned needs to have a certain movement in the image, while the template matching method requires the target to be positioned to have uniform characteristics; due to these limitations, the generality and flexibility of the existing target positioning methods are limited. Poor, difficult to meet the needs of the application

Embodiment Construction

[0061] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0062] The invention provides a positioning method for arranging targets in rows and columns, such as figure 1 The steps shown include:

[0063] S1. Read the image of the target to be located. The length and width of the image are xsize and ysize respectively; read the image, set the upper, lower, left, and right boundaries of the image, and determine the detection processing area.

[0064] S2. Perform column detection on the image to obtain the column information of the target to be located, specifically including:

[0065] S21. Perform vertical jump projection on the image to obtain a vertical jump projection array: A x [], for A x [] Carry out mobile smoothing with predetermined width l, and get the column fluctuation array: A1 x [] and then get the column fluctuation curve;

[0066] Using the jumping projection method, the tw...

Abstract

The invention provides a rank arrangement target locating method and system. The method can carry out rank and row detection on images after the images of targets to be located are read. The method can mainly utilize a bounce projection method to convert two-dimensional image data into one-dimensional fluctuation curve data to achieve the fluctuation situations of the targets, can analyze fluctuation curves to find out the positions of wave crests and the positions of wave troughs, can confirm the rank boundaries of the targets and the rank positions and further achieves location on the targets. By means of the rank arrangement target locating method, the rank arrangement targets can be located quickly.

Description

technical field [0001] The present invention relates to the technical field of digital image processing, in particular to a method and system for image positioning of objects arranged in rows and columns Background technique [0002] In the field of image processing and computer vision, target localization has always been a problem worth exploring. In industry, the application of image target positioning has greatly improved the quality and reliability of products and ensured the speed of production. In agriculture, the automatic positioning, identification and picking of fruits and vegetables have effectively improved the quality of picked fruits and vegetables, reduced the cost of picking, and improved labor productivity. In the military, accurate image matching positioning guidance is an important method to improve the accuracy of long-range missiles. In traffic management systems, image target location is used for vehicle license plate location recognition and so on. ...
