FIELD: plant growing; measurement.
SUBSTANCE: invention relates to the field of plant growing, and in particular to equipment for automated measurements of morphometric and spectral parameters of plants cultivated in in vitro conditions. Disclosed device for automatic measurement of plant parameters comprises a housing, light sources fixed behind video cameras, a support for placing the object under study, located at the bottom of the housing, and software for subsequent processing of obtained images. Body is made of a frame and detachable, light blocking panels. Multispectral radiation sources associated with the control controller are used as light sources. Stand for arrangement of measured object is a rotary platform made with possibility of rotation around vertical axis passing through its center, by means of electric drive connected to control controller through electric drive driver, as well as at least two photo-video cameras for obtaining images of the measured object are arranged on a movable platform, which is made with possibility of vertical movement by means of a helical transmission in a plane parallel to the axis of rotation of the rotary platform, by means of electric drive connected to control controller through electric drive driver. Software for further processing of obtained images is realized by a multichannel control and computing unit including a program logic integrated circuit for preliminary processing of images by filtration, elimination of distortion and if necessary stitching of images; a computer with GPU cores for mathematical processing of series of images from all views for each of the given illumination spectra and obtaining 3D model of the plant; a control controller; electric drive driver; non-volatile memory of data storage; as well as a built-in Ethernet interface for operator to transmit obtained results to remote workstation.
EFFECT: technical result is providing automatic measurements of plant growth and development parameters, constructing 3D model of a plant for use in scientific research in vitro using a multichannel control and computing unit, which provides control and processing of photo and video information, as well as determining and identifying fungal and bacterial manifestations of infections and plant diseases by having multispectral light sources with possibility of dynamic variation of the radiation spectrum of the illumination system.
