Image analysis techniques
10306738 · 2019-05-28 · ·

A frame is obtained from an image sensor. The frame may include a number of zones, each of which in turn includes a number of pixels. Each one of the pixels may be associated with a pixel value. A pixel change value for each one of the pixels in the frame may be determined based on an average pixel value of the pixel over a number of frames. The pixel change value for each pixel may then be normalized based on an average zone change value for the zone in which the pixel is located. The average zone change value may be based on the pixel change value for each one of the pixels in the zone. By using the average zone change value to normalize the pixel change value, an image frame may be analyzed in an efficient and fast manner.

10251245 · 2019-04-02 · ·

A method includes the steps of obtaining distance measurements between a device and a number of lighting fixtures, processing the distance measurements to assign coordinates to each one of the lighting fixtures, and facilitating registration of the coordinates of a subset of the lighting fixtures to obtain registered coordinates for all of the lighting fixtures. The coordinates indicate a relative location of each one of the lighting fixtures with respect to one another. The registered coordinates indicate a location of each lighting fixture in a desired coordinate space. Accordingly, a location of a lighting fixture within a desired coordinate space can be easily obtained, which may enable significant additional functionality of the lighting fixture.

10211660 · 2019-02-19 · ·

A lighting device system includes light emitters where a battery powers the light emitters. A battery supplies the power for powering the light emitters and a driver is arranged to selectively power the light emitters to adjust an operating parameter of the at least one light emitter based on the charge status of the battery. The driver may be in communication with a GNSS receiver that provides geospatial information used to adjust the at least one parameter. The driver may power the light emitters according to a non-adaptive light level profile and an adaptive light level profile where the light emitters consume less energy when operated under the adaptive light level profile than when operated under the non-adaptive light level profile. A processing device operatively coupled to memory determines, based on a state of charge of the battery, which profile to run.
