In each information-based research field of crops, qualitative and quantitative measurement, disease and pest and nutritional deficiency disease are in real time, automatic diagnosis, the classification of fruit grade, variety of crops is automatically in the research of identification, and how much is the key character in studying with color characteristic.At present, most professional image device can be proofreaied and correct the color of coloured image, but just in order to satisfy visual requirement, and be not content with the accurate correction that Science Institute requires.For this reason; In the analysis and research process of coloured image; Must seek a kind of suitable color correction device; To transform to the coloured image under the pre-determined standard light photograph at the coloured image that obtains under certain non-standard illumination condition, guarantee that color image color is undistorted, could reliability be provided for follow-up study.
The geometric correction of imagery at first will propose its Mathematical Modeling to the distortion physical process of image, reappears original image through its inverse process then, as the important step of image processing.Image rectification has extremely important application at numerous areas such as computer vision, robot vision, literal identification and image recognitions.The warpage of image is divided into two types: linear deformation and nonlinear deformation.Correction research at present to the linear deformation of image is more, and solves better, but the correction of image non-linear distortion still be the problem of the solution that fails.Traditional device is based on the linear deformation image correction apparatus of blind separation; Its thought is through the blind signal separation network; The horizontal ordinate of image mid point is reached value independently; Thereby make deformation pattern obtain proofreading and correct, but do not have versatility, promptly traditional means for correcting can't realize the distortion of plant leaf blade image and color is proofreaied and correct nonlinear anamorphose correction.
Summary of the invention
The purpose of the utility model is exactly the problem that exists to above-mentioned prior art; Design provides a kind of plant leaf blade image correction apparatus; Realization is by utilizing self-control acquisition correction standard form and the harmless leaf image of gathering; And, be reached for the purpose that succeeding crop image information intelligence research means provides the technical guarantee in early stage, ensures agricultural producer's interests to the geometry and the color correction of its distortion phenomenon.
The purpose of the utility model is achieved in that the plant leaf blade image correction apparatus forms by high-performance microprocessor, imageing sensor, dynamic memory, massage storage, I/O coffret and with reference to template, and image card control module, color of image correction module, image pretreatment module and image correction module are set in described massage storage; Each of device partly interface signal connects as follows: the function register of the signal GPIO emulation bus agreement SCCB control chart image-position sensor of high-performance microprocessor; 3 interrupt pin of high-performance microprocessor are introduced image output synchronizing signal VSYNC, synchronizing signal HSYNC, the synchronizing signal PCLK of imageing sensor, and 16 parallel-by-bit data of the passage YUV output of imageing sensor insert through 16 I/O interfaces of central processing unit; Dynamic memory has 2; Realize and being connected of high-performance microprocessor through the position extended mode; Wherein the data pin D0-D15 of a slice links to each other with low 16 position datawires of high-performance microprocessor; The data pin D0-D15 of another sheet links to each other with high 16 position datawires of high-performance microprocessor; Address wire pin A0-A12 and chip selection signal pin CS are interconnected mutually, and are connected with the pin nSCSO of high-performance microprocessor, and pin nWE, pin nRAS, pin nCAS also link to each other with corresponding pin LnWE, pin nSRAS, the pin nSCAS of high-performance microprocessor respectively; The pin ALE of massage storage and pin CLE end connect the pin ALE and the pin CLE end of high-performance microprocessor respectively; 8 I/O interface 7-0 links to each other with high-performance microprocessor least-significant byte data/address bus; Pin/WE, pin/RE, pin/CE link to each other with pin nFWE, pin two nFRE, the pin nFCE of high-performance microprocessor respectively, and pin R/B links to each other with pin R/nB; Constitute by 18 grey-level standard ash card with reference to template, have 4 standard control points to be used for proofreading and correct and demarcate.
The utility model is to the nature of distortion of plant leaf blade image with at correcting image cross-color correction link; Realized a kind of simple and effective color calibration method; In non-standard natural light environment, place the 18 grey-level standard ash card of the usefulness of making a video recording, will be in the average separately of the regional RGB component value of standard picture ash card, as the standard value of color correction; And the average separately of the RGB component value in the ash card zone of the image of taking down with non-standard natural daylight is compared; Obtain non-standard image RGB three looks correction coefficient separately, each pixel value of entire image is carried out color correction, thereby proofread and correct the color value of entire image with this coefficient.At the image geometric distortion correction link; This device is suitable for causing owing to the reason of stravismus angle arbitrarily the bearing calibration of image perspective distortion; Its algorithm is to come correcting image in the anamorphose front-back direction through FInite Element according to several known reference point in the image.This device provides technical guarantee and support for the plant information Intelligent treatment and the analysis in later stage.The utility model has the advantages that: operation quality is good, be easy to carry, and delicate structure, real-time, stable.
