Abstract
Foliar image has proven to manifest plant's health condition. Visual inspection, chemical analysis (leaf and petiole analysis), reflection or transmission of light, and image processing techniques are the major classifications of methods used for the purpose of evaluation of plants' health conditions. This invention is an embodiment of specialized light constricting enclosure housing an optical imaging device for the acquisition of digital foliar image for the purpose of post-processing. This image is preprocessed to render suitable for image analysis. A foliar specimen is disposed in a specimen platform through an opening on the front-side of the specialized enclosure.

FOLIAR IMAGE ACQUISITION TOOL
LI
This invention relates in general to an apparatus for acquisition or record of foliar image for ~~ the purpose of non-chemical analysis of the leaf through image processing. The apparatus ht can be used to take images of foliar samples from plant crops or from trees. The invention is = directed to an enclosure which embodies a diffusing membrane, an array of lighting Ba elements, a specimen platform and an imaging component. The invention is connected to a computing device that will store the specimen images and perform analysis. o
BACKGROUND no dim
Greenness of leaf has proven to be relevant to many requirements of crop monitoring to ~ assess the health condition of plants. Visual inspection, chemical analysis (leaf and petiole = analysis), reflection or transmission of light, and image processing techniques are the major =, classifications of methods used for the purpose of evaluation of plants’ health conditions. le
Among these methods, human visual inspections with or without using Leaf Color Chart LI (LCC) is the most common practice used by farmers in assessing whether the crops are well- fertilized or not during the season. This method, however, introduce much subjectivity in the results of observations, thus, there comes a need for a more objective yet still practical and convenient approach in crop monitoring and plant health assessment. Expensive methods of measurement of plant health condition may include the use of chlorophyll meters, and various laboratory tissue analyses.
PRIOR ART
Numerous inventions were published that used foliar samples to measure some morphological attributes of the mother plant where the sample was taken. An example of such was published as CN201331491Y which is a portable instrument for detection of chlorophyll relative content where the invention used a light emitting diode (LED) as light source, a photoelectric sensing circuit, and a single chip processing circuit as well as communication and data processing circuits. The problem with such instrument is that the sampled data cannot be taken as raw because it passed through digital processing in which inherent errors are introduced. Another invention published as CN202420471 that measures leaf area which is used to calculate growth information about the mother plant; whereas, the invention is comprised of microprocessor, an image sensor, a dynamic memory, a mass memory and a liquid crystal display (LCD) touch screen. In another patent, WO2016111376 (Al), the image of leaf is captured using an imaging device with light blocking capability and use an internal lighting system. The problem with this is the spectral response of foliar oo components of plants to artificial lighting. To obtain the natural response of foliar 40 components to light, natural lighting should be used. However, the intensity of natural light is not consistent.
In order to solve the above problems, the foliar image acquisition system of the present invention includes an enclosure made of light diffusing membrane, a specimen platform, an 45 imaging element, an optical system, a light source to augment the necessary level of light, and, a data medium for transmission of raw measurements to a computing device.
50 The present invention, in one illustrative embodiment, involves the image acquisition of foliar samples by placing the specimen in an enclosure that is comprised of an imaging
+ ’ Jom [a component, an array of lighting elements, a specimen platform, a high-reflectance inner » walls and a diffusing membrane. A leaf specimen is placed flat on the specimen platform. Lr ‘The inner light intensity is normalized to homogeneity by an array of lighting element. ~~ bot
In accordance with another aspect of the invention, an opening above the specimen platform = is placed to automatically crop the acquired image to the desired size. ap
A further feature of the invention involves the use of high-reflectance material for inner ~ walls of the specimen platform. This allows the even distribution of light onto the leaf specimen. Lr =
Moreover, in accordance with another aspect of the invention, a diffusing wall allows - natural light to diffuse towards the inner cavity where the leaf specimen is disposed. oy i
In accordance with another aspect of the invention, the array of lighting element is wrapped = with translucent material to diffuse the light evenly from the lighting element. tr
Referring more particularly to the drawings, the largest embodiment of the invention is the enclosure 101 which is made not to permit entry of external light. Attached on the higher extreme of the enclosure is the imaging device 102 of which the input is directly placed atop of the image cropping opening 103. The light required for image acquisition is provided by the array of lighting elements 104 which are a disposition atop the specimen platform.
Fastened on the side orthogonally placed to the specimen platform is a moving plane 105 which can be moved to allow the foliar specimen to be placed on the surface of the specimen platform.
In accordance to the illustration shown in Figure 2, the lighting elements are covered with diffusive material 201 that homogenizes the distribution of light onto the specimen placed on the surface of the specimen platform 202.
1. An image acquisition apparatus comprising, . at least one specimen cavity being able to contain a specimen or a plurality of specimens , at least one image sensor arrange infextreme position)in reference to the specimen cavity, {JT at least one lighting element covering the extents of the specimen cavity, and an enclosure that allows diffusion of external light into the specimen cavity. 19, 40 2. An image acquisition apparatus according to claim 1 wherein the enclosure embodies the specimen cavity, the lighting element, and the image sensor. 3. An image acquisition apparatus according to claim 1 wherein the specimen cavity reflects 45 light emanating from the lighting element and the diffused light from external of the enclosure.
