A method and system for controlling a power-transmission gear in a forest machine having a harvester head includes measuring a selected property of at least two trees with aid of observation means on a basis of electromagnetic radiation at a distance from the trees being measured to create measurement data. The power-transmission gear is controlled by software on the basis of the measurement data to change a state of the power-transmission gear to optimize energy required to perform an operation of an operating device. The operating device uses the energy transmitted by the power-transmission gear (after the change in state of the power-transmission gear so that operation of the operating device create a change in the attitude, location, or state of the harvester head.

The present invention relates to systems and methods for monitoring agricultural products. In particular, the present invention relates to monitoring fruit production, plant growth, and plant vitality. According to embodiments of the invention, a plant analysis system is configured determine a spectral signature of a plant based on spectral data, and plant color based on photographic data. The spectral signatures and plant color are associated with assembled point cloud data. Morphological data of the plant can be generated based on the assembled point cloud data. A record of the plant can be created that associates the plant with the spectral signature, plant color, spectral data, assembled point cloud data, and morphological data, and stored in a library.

A load scanning apparatus for taking physical measurements from a load. The load scanning apparatus has a scanning robot including a plurality of sensors arranged in an array spanning substantially across at least one load dimension in a first direction. The array of sensors moves together in a second direction, in a scanning plane. The plurality of sensors are configured to take images of the load from the scanning plane, and are configured to capture distance information about the distance of said load from the scanning plane.

Provided are a method and apparatus for measuring a geometric parameter of an object, and a terminal. The method includes: establishing a three-dimensional coordinate system based on a real environment, in accordance with a first depth image of the real environment photographed by a camera component; obtaining pose data of a terminal, obtaining a second depth image and a two-dimensional image of an object to be measured, and displaying the two-dimensional image on a display interface of the terminal; in response to a measurement point selection instruction, determining a coordinate in the three-dimensional coordinate system of a measurement point based on the pose data, the second depth image and the two-dimensional image, and determining a geometric parameter of the object to be measured based on the coordinate; and displaying, in the two-dimensional image, the geometric parameter of the object to be measured.

Disclosed herein are various devices, systems, and methods for use in agricultural, particularly for use in harvesting agricultural crop such as corn. Various implementations relate to methods and devices for measuring plant stalk cross-sectional area during harvest and providing additional methods of predicting and displaying yield on a row-by-row level in real time.

A fruit-on-tree sizing device includes a lower annular disc and an upper annular disc, from which first flexible arms and second flexible arms, with curved configuration, start internally, in opposite directions, and which respectively form a lower opening and an upper opening wherein the fruit is positioned. As the diameter of the fruit increases, the first flexible arms and the second flexible arms force the upper annular disc and the lower annular disc to rotate on themselves, in opposite directions. The device further includes a reading module intended for quantifying the relative movement of the upper annular disc with respect to the lower annular disc, and transmitter which transmits the measurements obtained to an external device.

A thickness measurement device is provided for measuring a thickness of a first layer of an entire plant leaf including the first layer and a second layer, the first layer having an incident surface and an opposing surface opposing the incident surface, the second layer being in contact with the opposing surface of the first layer. The thickness measurement device includes: a light source that causes light of a predetermined wavelength λ to enter the incident surface as an incident light from an air layer at a predetermined incident angle θ.sub.i; a spectroscopic camera that receives a combined reflected light obtained by combining first and second reflected lights, and acquires a two-dimensional image including a light intensity of an S-polarized light component perpendicular to the incident surface among the combined reflected light; and a controller that calculates the thickness t of the first layer by using a predetermined equation.

A three-dimensional measurement device includes an image data receiving unit, a camera position selecting unit, a stereoscopic image selecting unit, and a camera position calculator. The image data receiving unit receives data of multiple photographic images. The photographic images are obtained by photographing a measurement target object and a random dot pattern from multiple surrounding viewpoints by use of a camera. The camera position selecting unit selects camera positions from among multiple positions of the camera. The stereoscopic image selecting unit selects the photographic images as stereoscopic images from among the photographic images that are taken from the camera positions selected by the camera position selecting unit. The camera position calculator calculates the camera position from which the stereoscopic images are taken. The selection of the camera positions is performed multiple times in such a manner that at least one different camera position is selected each time.
