  • Patent number: 11100402
    Abstract: A system for image quality assessment of non-aligned images includes a first deep path portion of a convolutional neural network having a set of parameters and a second deep path portion of the convolutional neural network sharing a set of parameters with the first deep path convolutional neural network. Weights are shared between the first and second deep path convolutional neural networks to support extraction of a same set of features in each neural network pathway. Non-aligned reference and distorted images are respectively provided to the first and second deep paths of the convolutional neural network for processing. A concatenation layer is connected to both the first and second deep paths convolutional neural network, and a fully connected layer is connected to the concatenation layer to receive input from both the first and second deep paths of the convolutional neural network, generating an image quality assessment as a linear regressor and outputting an image quality score.

The recording zone for projection may be selected by the user, or be automatically selected based on configuration parameters of the HWD. Horizontal correction of the eyebox may be included. In an embodiment, multiple horizontal images are displayed in the selected recording zone, in different wavelengths. Another embodiment adjusts horizontal shift of the projected image based on user inputs. Other embodiments are described and claimed.

  • Patent number: 10718951
    Abstract: Systems, devices, and methods for beam combining within laser projectors are described. A laser projector includes first, second, and third laser diodes to generate red, green, and blue laser light respectively, a controllable scan mirror, and a heterogeneous beam splitter system. The red, green, and blue laser light have distinct maximum powers. The heterogeneous beam splitter system splits at least one of the red, green, and blue laser light and combines respective first portions of all three into an aggregate beam. Second portions of laser light are excluded from the aggregate beam. At the maximum power of each laser light the aggregate beam is white as defined by a target white point. The heterogeneous beam splitter system directs the aggregate beam towards the controllable scan mirror which scans the beam onto a projection surface. Decreasing the power of the laser light post-generation provides a larger range of aggregate beam colors.

  • Patent number: 10673203
    Abstract: The present disclosure generally relates to methods of assembling projectors, and more particularly, to methods of aligning laser diodes in laser projectors. Implementations of the present disclosure include positioning an alignment beam and a photodetector in an optical path of the projector. The alignment beam propagates from an alignment light source through a location where a laser diode is to be mounted. A laser diode is then initially positioned in the optical path with a laser cavity of the diode acting as a passive waveguide during the assembly process. The laser diode is then fixed in place at a position and, or, an orientation that corresponds to light from the alignment beam passing through a laser cavity of the diode to be aligned and registering at least a minimum threshold value of a measure at the photodetector.
