The disclosure provides a measurement garment and a measuring system. The measurement garment includes a first recognition pattern. The first recognition pattern is disposed at a stretchable part of the measurement garment, wherein the first recognition pattern comprises a first reference point and a second reference point, the stretchable part corresponds to a body part of a wearer wearing the measurement garment, and a specific distance between the first reference and a second reference point varies in response to the body part, and a variation of the specific distance is used for measuring a dimension of the body part.

A sensing device for measuring an offset along a longitudinal axis comprises a housing including a plurality of slots, two or more arrays of optical sensors aligned along the longitudinal axis, at least one of the arrays being offset along the longitudinal axis with respect to the other arrays and a microcontroller coupled to the two or more arrays of optical sensors and configured to determine a positional offset along the longitudinal axis at which light is detected by at least one of arrays of optical sensors. In some embodiments, each of the optical sensors of the arrays are positioned within the housing underneath one of the plurality of slots to reduce an angle of incidence of radiation received.

A measurement system for measuring a dimension of an object includes a rotary encoder and a rotatable wheel connected to the rotary encoder. A first transfer roller is separated from the rotary encoder by a first predetermined distance. A connector having an inner surface opposed to an outer surface engages with the rotatable wheel so that the connector moves in sync with the rotatable wheel. The connector engages between the first transfer roller and the object so that the connector moves in sync with the object.

An apparatus for generating a cross-sectional abdominal image includes a memory for storing a cross-sectional abdominal image, a measuring unit for measuring an outline of an abdomen, and a controller configured to correct the cross-sectional abdominal image based on the outline of the abdomen measured by the measuring unit.

Aspects of the subject disclosure may include, for example, obtaining a first plurality of circumference measurements, each of the first plurality of circumference measurements corresponding to a first circumference around a limb of a person at a respective one of a plurality of locations of the limb, each of the first plurality of circumference measurements being obtained from a respective one of a plurality of elastic measurement elements that is positioned at a respective one of the locations; determining, based upon the first plurality of circumference measurements, a first geometric profile along a length of the limb; and outputting data representing the first geometric profile. Other embodiments are disclosed.

A self-calibrating system, apparatus, and method for accurately measuring a volumetric capacity of a tank. The system, apparatus and method comprise: a mechanism that adjusts a level of a platform; a light-emitting device with beam-like optics (laser, diode, etc.) mounted to the platform; mechanism for adjusting alignment of the light-emitting device with respect to the platform; a mechanism for rotating the platform by variable angles, including by 180-degrees; one or more level sensors (such as, for example, spirit levels, tilt sensors, or other devices) that provide feedback on the alignment of the platform normal to the gravity vector.

An inner circumferential length measurement method includes the steps of: disposing a two-dimensional sensor at a predetermined measurement position on an inner side of the circular member placed flat in an unrestrained state on a support so that the two-dimensional sensor faces an inner circumferential surface of the circular member in a non-contact state; rotating the two-dimensional sensor about rotation shaft at a predetermined position on the inner side of the circular member; measuring a separation distance from the two-dimensional sensor to the inner circumferential surface around an entire circumference of the circular member; and calculating an inner circumferential length of the circular member via a calculation unit using the separation distance measured and a distance from the rotation shaft to the two-dimensional sensor in a plan view.

The present disclosure is related to agricultural devices, system, and methods, particularly for detecting and measuring plant stalks during harvest. The system may comprise a harvesting row unit, with a camera, a processing unit, and an in-cab display. The system may additionally include a stalk alignment guide, a leaf shield, an artificial light source, and/or a lens cleaning apparatus.
