Preferably, described light source 1 adopts linear White LED light source.
Preferably, in the present embodiment, the width 500mm of object stage 2, length 400mm, irony, second area 2b surface mount one is printed on black and white chessboard case marker and determines the plastics cardboard of plate；First area 2a lays slide block 5 able to programme, and slide block 5 length is 400mm, wide for 50mm, is highly 110mm, and effective travel is 300mm；Install a linear LED array light source 1, light source 1 length 300mm, width 10mm on slide block 5 top, the distance of light source 1 and object stage 2 is 110mm；Preferably, described slide block 5 can slide along its length, lays diffuse-reflectance and demarcate object, long 400mm, wide 30mm on the right side of slide block 5；Laying eyeglass 3, long 400mm, wide 30mm between described slide block 5 and described blade, described eyeglass 3 lies on described second area 2b, is used for calculating the shift length of slide block 5.Tested blade will be positioned over the second area 2b at eyeglass 3 place, and secures the vanes to second area 2b surface by Magnet frame 6.Slide block 5 can pass through programming Control, makes slide block at the uniform velocity move along its length, and in the present embodiment, setting speed is the 20mm/ second.
Object stage 2 is fixed on turntable 7, and is connected with slide rail 8 by turntable 7, it is preferred that described turntable 7 can move at the axis direction of described slide rail 8.Slide rail 8 connects support 9, and universal turning bench 10 is fixed on support 9 top, in the present embodiment, The Cloud Terrace is installed Canon's single-lens reflex camera, and spider 11 is installed in turntable 7 bottom.Preferably, described turntable 7 includes shell 7a and rotating shaft 7b, described rotating shaft 7b is horizontally disposed in the inside of described shell 7a, described shell 7a can rotate around rotating shaft 7b, owing to object stage 2 is arranged on described turntable 7, object stage 2 also can deflect around rotating shaft 7b, and maximum deflection angle is ± 45 °.Turntable 7 utilizes slide rail 8 along slide rail 8 axis direction moving stage 2, can to adjust telescoping shoring column 9 and control image mechanism 4 height, and universal turning bench 2 controls image mechanism 4 shooting angle, adjusts spider 11 and can control the height of object stage 2.Utilize said structure, can control flexibly for the different height of plant leaf blade, orientation etc., simultaneously, when universal turning bench 10 and support 9 are adjusted fixing after, namely the position of image mechanism 4 and object stage 2 view area is fixed, no matter for which kind of plant leaf blade, turntable 7, spider 11 and slide rail 8 are adjusted, all will not change image and find a view size, therefore can ensure that the stability of geometric proportion in each image.
Preferably, described support 9 is telescopic bracket 9, for regulating the position of image mechanism 4.In the present embodiment, in data acquisition, image mechanism 4 adopts Canon's slr camera to carry out video capture, the video of 1920*1080 resolution is recorded under MANUAL CONTROL mode, the parameters such as time of exposure, aperture, exposure rate are fixed, and concrete numerical value is variant according to Xiang Jixinghao camera lens model difference.Focus settings is that diffuse-reflectance can be demarcated the numerical value that object, eyeglass and measured leaf region are integrally incorporated in image, and therefore focal length numerical value can be otherwise varied according to plant leaf blade size.
The image sequence gathered is utilized to extract blade surface diffuse-reflectance information approach as follows, video is converted into sequence of pictures, for 200 image sequences, gridiron pattern image is found from image sequence, the X/Y plane coordinate of each pixel on the three-dimensional position of camera, image is accurately calculated by the available computer calibration technique of this image, due to tested blade, thing is demarcated in diffuse-reflectance, mirror is both placed on object stage 2, can be similar to it all on the two dimensional surface of Z=0.LED light source 1 can form bright light belt when mobile on eyeglass 3, on different images, the position of optic strip is different, we find two images occurring light belt at first and finally, and calculate the three-dimensional coordinate of light belt in image, undertaken both coordinates subtracting each other the displacement that can obtain the moment light belt at two images, again divided by the amount of images at interval in both images, the speed that on every image, light source moves can be obtained, and then light source three-dimensional coordinate at any time can be calculated.Due to when light source 1 occurs in directly over blade table cake, this high light reflectivity is negligible, the color presented is the mapping of diffuse-reflectance information, therefore the diffuse-reflectance color value of any point can be chosen from image sequence according to light source position, in order to get rid of the impact of light intensity, we utilize the color value that thing is demarcated in diffuse-reflectance that the diffuse-reflectance color of blade table cake is corrected.And this device possesses portable feature, can use in field or facilities environment, breach conventional laboratory environment.Device is operated in process, without plant leaf blade is taken off, directly under plant growth state, realize information gathering, ensure that the accuracy of data and verity, the blade diffuse-reflectance colouring information collection of the staple crops such as Semen Maydis, Oryza sativa L., Semen Tritici aestivi, Fructus Cucumidis sativi, Citrullus vulgaris, Fructus Melo and plant can be realized respectively.
During use, after the fixing blade sample of Magnet frame to object stage, open camera recorded video, start slider-actuated light source automatic uniform speed to run, rate travel is 20mm/s, will return according to Automatic Program after slide block movement to end point, takes off blade during returning, record the gridiron pattern on 1 second object stage, finally stop recorded video.The video finally given is that in image, tested scene geometric position is motionless, the video that only colour brightness changes.
In sum, the plant leaf blade lossless harvester of diffuse-reflectance color that this utility model embodiment provides, by light source 1 being arranged at the top of slide block 5, and slide block 5 is placed on the first area 2a of object stage 2, blade is placed on the second area 2b of object stage 2, described eyeglass 3 is arranged at described second area 2b and is between slide block 5 and blade, can measure when not destroying plant growth state；The light source that level is installed is under slide block 5 drives, and at plant leaf blade surface scan, simultaneous camera structure 4 carries out high-definition camera and completes texture and the collection of color image sequence, provides brand-new technological means and utility for plant leaf color diffuse-reflectance collection.Realize plant leaf blade diffuse-reflectance colouring information collection accurate, automatic, efficient.
