    Abstract: Disclosed herein is a livery printing system and a method of generating a control path. The system includes a training system having a processor and a memory with code configured to cause the processor to receive a 3D digital model associated with an object; generate simulated control paths, based on the 3D digital model, for actuators of a printing device with printheads, determine a reward value for each one of the simulated control paths based on a simulated physical value, a simulated surface coverage value, or a simulated printing speed value. A value of one simulated control path variable of any of the simulated control paths is different than the value of the simulated control path variable of another simulated control path. One of the simulated control paths is selected based on a comparison between the reward values determined for the simulated control paths.

    Abstract: Methods for selecting a path of a multi-component end effector along a surface, robots that perform the methods, and storage media that directs robots to perform the methods. The multi-component end effector is attached to a robot, which is configured to move the multi-component end effector along the surface on a continuous tool centerpoint path (TCP). The multi-component end effector includes a plurality of end effector elements configured to move relative to one another. The method includes providing a discretized TCP that includes a plurality of spaced-apart waypoints along the continuous TCP. The method also includes determining a plurality of distance heuristics. The method further includes updating the plurality of distance heuristics to define a plurality of updated distance heuristics. The method also includes selecting the path of the multi-component end effector along the surface based upon the plurality of updated distance heuristics.

    Abstract: Systems and methods for assessing the calibration of an array of cameras. The method including inputting into a processor captured images from at least two cameras of the array of cameras, the captured images having features from an image. The method further including extracting one or more extracted features from the captured images, matching one or more extracted features between pairs of the at least two cameras to create a set of matched features, selecting matching points from the set of matched features, generating a three-dimensional reconstruction of objects in a field of view of the at least two cameras, and outputting the three-dimensional reconstruction wherein the three-dimensional reconstruction comprises indicators of calibration errors.

    Abstract: A method of developing an automatic control plan for printing on a contoured surface is disclosed. The method includes scanning a contoured surface with a surface scanning device to produce a contoured data set, and creating a multi-dimensional model, with a computing device, of the contoured surface based on the contoured surface data set. Additionally, the method includes inputting a multi-dimensional model of a printing array and an image to be printed onto the contoured surface, into the computing device. The method further includes simulating, on the computing device, a plurality of movements performed by the printing array and a printing by the printing array to apply the image on the contoured surface. Additionally, the method includes, compiling, on the computing device, the automatic control plan which is programmed to execute the plurality of movements of the printing array to apply the image on the contoured surface.

    Abstract: An example method includes determining first classification rule(s) based on first data that classifies pixel groups of first reference image(s) as types of objects. The first reference image(s) are captured by a first sensor. The method further includes determining second classification rule(s) based on second data that classifies pixel groups of second reference image(s) as types of objects. The second reference image(s) are captured by a second sensor. The method includes classifying, as respective first objects, pixel group(s) of a first image of a scene based on the first classification rule(s). The method includes classifying, as respective second objects, pixel group(s) of a second image of the scene based on the second classification rule(s). The method further includes determining whether a change occurred in the scene based on the object classification of the first image(s) and the second image(s).
