Calibration methods use a calibration target for obtaining the intrinsic and extrinsic camera parameters of one or more cameras are. The methods can include acquiring, with each camera, a sequence of target images representing the calibration target in different target poses and at different acquisition times. The methods can include identifying reference images from the target images, and defining volume bins, angle bins and multi-camera bins into which the reference images are stored. The reference images can be used to determine the intrinsic and extrinsic parameters of the one or more cameras. In some implementations, the calibration methods can enable a user to monitor the progress of the calibration process, for example by providing an interactive calibration target including an input/output user interface to guide the user in real-time during the acquisition of the target images and/or sensors to provide positional information about the target poses.

Camera calibration method using a calibration target

There is described a system and a method for analyzing spots in a micro-array, the spots containing targeted specimen, the method comprising the steps of: providing a slide with a micro-array of the spots thereon; illuminating at least one of the spots; directing the light onto the at least one spot; collecting light emitted from the at least one spot; forming an image of the at least one spot using the collected light; and analyzing the image to distinguish at least one unit of the targeted specimen located within the at least one spot from any undesired material. The analysis results are aimed at the detection, classification and quantification of optically resolvable specimen such as micro-organisms or cells.
