摘要： 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.

摘要： An ultrasonic flow-rate measurement device and an ultrasonic flow-rate measurement method capable of accurately measuring a flow rate of a fluid to be measured with a simple configuration are obtained. A reference-sound-pressure distribution waveform holding unit (60) holds a reference sound pressure distribution waveform based on an ultrasonic pulse emitted from a transmitter (10) and incident on at least three receivers (20) in a state where a flow velocity of a fluid (G) to be measured in the pipe (5) is zero. A variable-sound-pressure distribution waveform acquisition unit (70) acquires a variable sound pressure distribution waveform based on the ultrasonic pulse emitted from the transmitter (10) and incident on the at least three receivers (20) in a state where the flow velocity of the fluid (G) to be measured in the pipe (5) is not zero. A flow-rate calculation unit (80) obtains a shift amount (S), which is a difference between the reference sound pressure distribution waveform and the variable sound pressure distribution waveform, and integrates the shift amount (S), thereby calculating a flow rate of the fluid (G) to be measured in the pipe (5).
