An object detection device of an object detection system includes an object detection determination unit including a bird candidate determination unit for determining, from an image acquired by imaging a moving object, whether or not the moving object is a specific detection subject (bird in this case), and a bird type/attitude estimation unit for estimating, based on a contour of the moving object determined to be the bird by the bird candidate determination unit and a WFM library storing contour shape information, which is a contour prepared for each of types of the specific detection subject (types of the bird in this case), a type of the moving object out of the types of the specific detection subject.

Object detection device, object detection method, and object detection system

An object detection apparatus is capable of estimating the size of a moving object easily based on images. An object detection apparatus () of an object detection system () includes an object detection/determination unit () configured to analyze a period of motion of the object based on the images to estimate a size of the object based on the period of motion of the object.

An ultrasonic multiphase flowmeter, a flow rate measurement program and a multiphase flow rate measurement method using an ultrasonic wave that can measure the flow rate of a multiphase flow by detecting the position of an interface between phases by an operation processing of at least one of data on reflected ultrasonic wave and data on a flow velocity distribution are provided. The ultrasonic multiphase flowmeter functions to transmit/receive ultrasonic waves, calculate flow velocity distributions, determine interface positions, and calculate flow rates.
