The present disclosure provides a technique which makes it possible to evaluate a state of a cell aggregation of one or more spheroids. In the culture state determination device according to the present disclosure, a plurality of light sources sequentially illuminate a plurality of cell aggregations put on an image sensor. The image sensor acquires captured images of the plurality of the cell aggregations each time when the plurality of the light sources illuminate the plurality of the cell aggregations. Control circuitry extracts a region including an image of the cell aggregation in the captured image; generates three-dimensional image information of the region using a plurality of the captured images; extracts an outer shape of the cell aggregation and a cavity part inside the cell aggregation using the three-dimensional image information; calculates a first volume that is a volume based on the outer shape of each of the cell aggregation and a second volume that is a volume of the cavity part based on the cavity part of each of the cell aggregation in the three-dimensional image information; and determines a culture state of the cell aggregations using the first volume and the second volume.

A method for measuring a depth of field is provided. An initial depth-of-field data is acquired through two optical lens modules and another depth-of-field data is obtained according to the phase detection pixel groups of the image captured by one of the optical lens modules. Consequently, even if objects in the scene are arranged along the same direction as the two optical lens modules, the error of the initial depth-of-field data can be compensated. Moreover, an image pickup device using the method is provided.

A Pulsed Thermography (PT) system and method is provided utilizing a long duration pulse in combination with a radiant heat shield as a non-destructive testing method for quantitatively measuring defect depths within a 3D printed part and for characterizing layer-by-layer surface defects in the 3D printed part.

Disclosed is a method and system for processing images from an aerial imaging device. An image of an object of interest is received from the aerial imaging device. A parameter vector is extracted from the image. Image analysis is performed on the image to determine a height and a width of the object of interest. Idealized images of the object of interest are generated using the extracted parameter vector, the determined height, and the determined width of the object of interest. Each idealized image corresponds to a distinct filled volume of the object of interest. The received image of the object of interest is matched to each idealized image to determine a filled volume of the object of interest. Information corresponding to the determined filled volume of the object of interest is transmitted to a user device.
