Provided are systems and methods for camera alignment using pre-distorted targets. Some methods described include selecting a configuration of shapes, and determining targets by pre-distorting the shapes according to the inverse of the distortion function of the lens system to be aligned. Images of pre-distorted targets are then compared to the original configuration of shapes, to perform camera alignment. Alignment is thus accomplished in simpler and more accurate manner. Systems and computer program products are also provided.

Examples are provided related to using multiplexed diffractive elements to improve eye tracking systems. One example provides a head-mounted display device comprising a see-through display system comprising a transparent combiner having an array of diffractive elements, and an eye tracking system comprising one or more light sources configured to direct light toward an eyebox of the see-through display system, and also comprising an eye tracking camera. The array of diffractive elements comprises a plurality of multiplexed diffractive elements configured to direct images of a respective plurality of different perspectives of the eyebox toward the eye tracking camera.

In order to enable high image acquisition rate with simultaneous low energy consumption of a camera 1, a camera (1), in particular a 3D time-of-flight camera, is provided, comprising an illumination unit (2) which emits light pulses during an illumination phase (Bp), an image sensor (3) which generates images from the light pulses reflected by an object, a switching controller (4) which controls current to the illumination unit (2), the switching controller (4) being operable in a continuous and a discontinuous mode (CCM; DCM), and a control unit (5) which is designed to activate and deactivate the continuous mode (CCM) of the switching controller (4) as a function of the illumination phase (Bp) of the illumination unit (2).

In one example, a system for evaluating an agricultural material is provided. The system comprising: a housing having a passage in or through an interior of the housing with an inlet for receiving agricultural material and an outlet for outputting the agricultural material; a wall opening in a wall of the passage; and an imaging device having a window located within a border, the imaging device having a removable portion with at least one of a moisture absorbing material, a heat source, and an anti-fog agent within the removable portion.

Provided is a cable and joint inspection system, process and computer readable medium enabling cable and joint inspection functions. The system includes an x-ray cabinet containing an x-ray camera and positioning equipment. The x-ray camera is positionable to obtain an x-ray image of a portion of a cable or a cable joint. The x-ray images are evaluated to determine whether a bounded area is within the x-ray image. The processor may measure the size of the bounded area in the x-ray image based on a number of pixels forming the bounded area. In response to the size of the bounded area being greater than an inclusion or void allowance threshold, the processor may flag the bounded area as an inclusion or void and flag pixel locations in the x-ray image. The flagged pixel locations correspond to a physical location within the portions of the cable or the cable joint.
