An automated log scaling system and associated methods are disclosed. In the system and methods, one or more imagers may capture depictions of respective first ends and/or second ends of a plurality of logs, and use the captured depictions to scale the plurality of logs. A diameter value for each end of the log may be determined using the captured depictions. Relative location values for each captured end may be determined and used to form a length of each log. Information captured in the images is used to identify the type of tree or species of tree for each log. At least one of the diameter values may be multiplied by the determined log length, and the resulting product value may be compared to values in a log scaling chart to determine a value for the log. The value of multiple logs may be used to form a load of logs for distribution.

A scan using a pulsed distance measuring light with two wavelengths of which reflectances are different with respect to a content of a nitrogen by a laser scanner, the two wavelengths are separated, lights are received, a distance measurement value and a light amount are detected for each pulsed distance measuring light and for each of the two wavelengths, a height of a crop is detected based on the distance measurement value, a received light amount ratio of the two wavelengths is detected, and a growth condition of the crop is detected based on the detected height and the received light amount ratio.

Devices and methods for attaching objects to living trees. Various forms of the devices employ a cable that is sized to be wrapped around a circumference of a portion of the living tree and engaged by at least one friction generating member to retain the cable attached to the portion of the living tree without human intervention until another circumference of the portion of the living tree exceeds a length of the cable to enable the cable to automatically disengage the portion of the living tree without the human intervention.

The disclosed apparatus, systems and methods relate to a physical stalk sensing system comprising at least one resilient member. Sensors having the resilient member or members are able to estimate the size of the stalks of row crops as they pass through a field, such as a corn field. The sensors can be mounted on a corn head and the results can be analyzed and visualized. A system for predicting crop yields in real-time or near real-time. A system for adjusting a stripper plate gap.

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 devices, systems, and methods for increasing yield by emitting warnings when the corn head to not at the proper height.

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.

Provided is a system for detection and analysis of a fibrous root system architecture of a plant, including a plant pot having at least one slit area extending through a cross section in an axial direction, at least one laser measuring unit, and a data analyzing unit, where each laser measuring unit has a laser transmitter and a receiver disposed corresponding to the slit area in such a manner that a laser beam emitted from the laser transmitter to the receiver goes across the cross section of the plant pot; measurement on all roots in the slit area is realized by a rotating stage, and the laser measuring unit swinging horizontally around the laser transmitter within a predetermined angle range; and the data analyzing unit is configured to perform statistical analysis on the roots of a plant to be measured according to laser measuring results.

Described is a forest monitoring system and method. Monitoring is performed continuously and remotely and evaluates factors such as growth and health, as well as climate and environment variables in forests, wooded surfaces or thus identified surfaces, using wireless data transfer.

A harvester (1), comprising a harvester aggregate (2) for felling, trimming and preparing tree trunks, a first measuring device (I) provided in connection with the harvester aggregate (2) for measuring of at least one dimension of a tree trunk. The harvester comprises a second measuring device (II) for measuring a feature of the first measuring device, whereby said feature is an attribute reflecting the capability of the first measuring device to measure said dimension correctly, and a control unit (11) configured to make a comparison between an actual value (a) of the measured feature and a target value (β) of said feature, whereby the target value is indicative of a state of the first measuring device, where its measurement of said dimension is considered to be correct.

In one aspect, a method for generating agricultural treatment prescriptions includes generating a pre-emergence field contour map for a field based on pre-emergence aerial data collected for the field, the pre-emergence field contour map being indicative of the ground surface topology of the field in a pre-emergence condition. The method also includes generating a post-emergence field contour map for the field based on post-emergence aerial data collected for the field, the post-emergence field contour map being indicative of a field topology of the field following plant emergence. In addition, the method includes identifying individual plant heights of the plants based at least in part on a comparison between the pre-emergence field contour map and the post-emergence field contour map, and determining a treatment prescription for applying one or more agricultural products to the field based at least in part on the individual plant heights.
