摘要:
This fish counting system (3) comprises: an image acquisition unit (30) that acquires a plurality of images obtained by capturing, over time, images of a photographing area in which a fluid including a fish (1) flows; an extraction unit (31) that extracts a fish in each image; and a counting unit (34) that counts the number of fish. The photographing area has a first area (Ar1) and a second area (Ar2). The counting unit (34) counts the fish when the fish in the first area (Ar1) moves to the second area (Ar2).
摘要:
Provided is a technique for reducing erroneous detection by outputting highly reliable results regarding the number of people. A mobile object measurement system of the present disclosure is a system for extracting the number of people on the basis of the measurement results of measurement devices that are arranged in the entire measurement area, and is configured to extract measurement devices that are measuring a predetermined area, extract the number of people present in the predetermined area using a plurality of combinations of measurement devices including some of the extracted devices or a plurality of combinations of measurement devices having different system start times, and perform a voting process for each extracted number of people for each combination so as to determine the most reliable number of people as a correct number of people

A cigarette inspection device designed to obtain an image showing filter end faces of a bundle C of filtered cigarettes arranged side by side with their axes parallel to one another, analyze the image and determine whether the bundle is short of filtered cigarettes comprises a first determination section which determines how many filtered cigarettes are arranged side by side from contours of filter end faces in the image generated, and determines whether the bundle consists of a predetermined number of filtered cigarettes, and a second determination section which determines whether the first determination section has falsely recognized one cigarette as two.

A particle sorting cell (10) comprises a cavity (12), an inlet (16) of a fluid flow (14) into the cavity, a first outlet (18) of a first part (22) of the fluid flow out from the cavity and a second outlet (20) of a second part (24) of the fluid flow out from the cavity. The second outlet is displaced from the first outlet in a first direction (Y) transverse to the flow direction (X). An acoustic generator (40) is arranged to apply an acoustic standing wave. The standing wave is transverse to the flow direction as well as to the first direction. A controller (42) is arranged to control a selective operation of the acoustic generator in dependence of an input data signal (44) associated with a particle (32) comprised in the fluid flow. The particle (32) can selectively be separated into the first outlet or the second outlet.
摘要:
A method and apparatus for determining a pose of an elongate object and an absolute position of its tip while the tip is in contact with a plane surface having invariant features. The surface and features are illuminated with a probe radiation and a scattered portion, e.g., the back-scattered portion, of the probe radiation returning from the plane surface and the feature to the elongate object at an angle tau with respect to an axis of the object is detected. The pose is derived from a response of the scattered portion to the surface and the features and the absolute position of the tip on the surface is obtained from the pose and knowledge about the feature. The probe radiation can be directed from the object to the surface at an angle sigma to the axis of the object in the form of a scan beam. The scan beam can be made to follow a scan pattern with the aid of a scanning arrangement with one or more arms and one or more uniaxial or biaxial scanners. Angle tau can also be varied, e.g., with the aid of a separate or the same scanning arrangement as used to direct probe radiation to the surface. The object can be a pointer, a robotic arm, a cane or a jotting implement such as a pen, and the features can be edges, micro-structure or macro-structure belonging to, deposited on or attached to the surface which the tip of the object is contacting.
