Production and qualification of electronic cameras currently requires the use of optical target projectors. The quality of the target projectors used impacts the quality of the final products. We designed and constructed an apparatus for evaluating target projector parameters, such as the projection distance, target backlighting, projector FoV and projection quality. This device allows us to qualify optical target projectors and to perform long term and under stress tests.
In current camera sensor-objective alignment approaches for an automotive industry, slow and iterative scan methods are widely used with a cycle time not fully compatible with contemporary production lines. New method is proposed to facilitate immediate active alignment of the sensor comprising a focal plane array and an objective. The method is based on a single-shot sensor data read-out with unknown absolute and correct alignment positions in all six degrees of freedom. First three unknown alignment values can be calculated based on a classical centroid approach, while the remaining three are calculated using an AI model. This immediately leads to massive production line simplification and cost reduction, so important for the automotive industry.
