1. A method comprising:
receiving data characterizing an image of an inspection region of an industrial machine acquired by an inspection device configured to inspect the inspection region, wherein the inspection device includes a camera and a light source, wherein the camera has a first position and a first orientation and the light source has a second position and a second orientation when the image is acquired;
identifying a defect in the inspection region of the industrial machine based on the received data characterizing the image of the inspection region, wherein identifying the defect in the inspection region comprises calculating a defect probability value associated with the defect in the inspection region, and wherein the calculation is based on comparison of the data characterizing the image with data characterizing images of inspection regions in a database;
determining that a new image of the inspection region needs to be acquired, wherein the determination that the new image of the inspection region needs to be acquired is made when the defect probability value is between a first threshold value and second threshold value;
varying a position of the camera, an orientation of the camera, a position of the light source, and an orientation of the light source by an articulation section of the inspection device driven by a driver that is controlled by a controller responsive to determining that a new image of the inspection region needs to be acquired; and
acquiring data responsive to determining that a new image of the inspection region needs to be acquired and after varying the position of the camera, the orientation of the camera, the position of the light source, and the orientation of the light source, the data characterizing a 3D point cloud by a structured light emitter and structured light detector or a second image of the inspection region.
