Embodiment
Below through embodiment and combine accompanying drawing that the utility model is done further to describe in detail, but be to be understood that the utility model is not placed restrictions on by following content.
Embodiment 1: (bottle green green vegetable leaf chart is as the collection of information)
A kind of leaves of plants chart is as the information acquisition camera bellows, and this camera bellows comprises casing 1, shading curtain rod 2, leading screw crank 3, window-blind 4, white light source 5, clear glass 6, separated optical cavity 7, ground glass 8, blade feeding mouth 9, rubber roller 10, roller crank 11, feed rod 12, leading screw 13, CCD camera 14, adapter sleeve 15, location-plate 16, inserts mouth 17.
Wherein, shading curtain rod 2 and window-blind 4 are equipped with in the front of casing 1, and all the other five faces are sealing; This casing 1 is divided into two-layer up and down by the thick ground glass 8 of 0.6cm; In the upper strata: the rear of ground glass 8 is fixed with the location-plate 16 that a left and right sides is provided with shrinkage pool; Directly over this plate, establish adapter sleeve 15, be provided with in the left and right sides of this cover and the corresponding penetrating circular hole of 16 liang of shrinkage pools of location-plate; Leading screw 13 passes adapter sleeve 15 left side circular holes, and its lower end activity orientation is in the shrinkage pool of the left side of location-plate 16, and its top is stretched out outside casing 1 top layer and with leading screw crank 3 and is connected; After feed rod 12 passed adapter sleeve 15 right side circular holes, its lower end was fixed in the right side shrinkage pool of location-plate 16, and its upper end fixes with casing 1 top layer below; CCD camera 14 is fixed in the below, front side of adapter sleeve 15; The rubber roller in location 10 backs, 8 0.3～0.5mm places of ground glass form a slit below the right edge distance of ground glass 8; Parallelly with this corresponding section, slit on the right flank of casing 1 offer a wide slit; Blade feeding mouth 9 is formed in this two slit, is connected with roller crank 11 in the forward end of rubber roller 10; In lower floor: below ground glass 8 apart from the parallel clear glass 6 of establishing in 3.8mm place; Form between this clear glass 6 and the ground glass 8 at a distance from optical cavity 7; And on the right flank of casing 1 with should be at a distance from the parallel slit that to offer a height be 3.8mm, corresponding section, right-hand member limit of optical cavity 7, the insertion mouth 17 of stained glass paper is formed in this two slit; Parallel beneath at clear glass 6 is provided with the white light source 5 that adjustable light intensity is 8000～10000 candelas.
When gathering bottle green green vegetable leaf chart as information; Green vegetables blade to be measured is fed from blade feeding mouth 9; Force blade from the slit that rubber roller 11 and ground glass 8 form, to push and mistake through turn roller crank 11 limits; Fold and the bending on the blade removed on the limit, and the limit will this blade after smooth be transferred into the following orientation of CCD camera 14; Turn leading screw crank 3 adjustment whole blade are included within CCD camera 14 visuals field, adjust the focal length of cam lens again through means, to obtain distinct image; If only seek out blade profile information; Can suitably reduce light intensity to 8000 candela; With the influence of avoiding blade interior lines information that later image is handled, if seeking out the blade texture information can suitably increase light intensity to 10000 candela, to highlight leaf table detailed information; Consider that the green vegetables blade is a bottle green, can when implementing Digital Image Processing, help the extraction of green target under the red background like this with individual red glass paper (green complementary color) by inserting mouthful 17 insertions in optical cavity 7; Pulling on window-blind 4 avoids the interference of extraneous light to make a video recording; Last camera is through the video Data Transmission line, the view data of blade passed to computing machine store.
Embodiment 2: (light green color pakchoi leaf chart is as the collection of information)
In this example,, for avoiding the influence of high light, the intensity of white light source 5 is reduced to 6000～7000 candelas, and 2 red glass paper are inserted in optical cavity 7 by inserting mouthfuls 17 video information according to the more shallow characteristics of pakchoi leaf color; All the other camera bellows structures and leaf chart are same as embodiment 1 as the method for information acquisition.
Embodiment 3: (red red maple leaf chart is as the collection of information)
In this example; The intensity of white light source 5 is 8000～10000 candelas, considers that red complementary color is a light green color, therefore 1 green glass paper is inserted in optical cavity 7 by inserting mouth 17; To increase the contrast of red blade and background area, help extracting the apparent information of red blade; All the other camera bellows structures and leaf chart are same as embodiment 1 as information collecting method.
Embodiment 4: (the cucumber leaves leaf chart of white powder scab is as the collection of information)
In this example; What pay close attention to is the area and the quantity of the white scab of cucumber leaves powdery mildew; Therefore in optical cavity 7, do not insert the viscose paper of any color; And the brightness of strengthening white light source 5 is 12000～15000 candelas, to strengthen the contrast of scab zone with leaf area, is convenient to obtain to extract the scab view data of characteristic; All the other camera bellows structures and leaf chart are same as embodiment 1 as information collecting method.
