Systems and methods disclosed herein includes a measurement device to enable dimensional metrology and/or 3D reconstruction of an object. The measurement device is positioned between the object and reference luminaires (e.g., light emitting diodes or other light sources). The measurement device uses the reference luminaires to determine the position and orientation of the measurement device. The measurement device may include a camera oriented towards the reference luminaires and may acquire/use images of reference luminaires to determine the position and orientation of the measurement device. Using the reference luminaires, the system may determine positions and orientations of the measurement device when the images of the reference luminaires are taken. The system may be configured to use the positions and the orientations of the measurement device to determine dimensions and/or 3D models of the object.

Method and apparatus for light and computer vision based dimensional metrology and 3D reconstruction

Techniques are disclosed for decoding light based communication (LBC) messages transmitted between a transmitter device and a receiver device. The receiver device includes a processor that executes a process to decode a received LBC message. The processor determines a moving average and removes the moving average to provide a second digital message (with the moving average removed), to account for any noises or interferences. The moving average may be determined using a length-preserving moving average. The peak location in the second digital message is identified and used as a start position for synchronization when the peak location is above the threshold. Sampling points are derived, and logical maximum and minimum values (1's and 0's) are assigned to one or more of the sampling points. The logical values are decoded to generate a decoded sequence of data representative of the received LBC message.

Techniques for decoding light-based communication messages

Aspects of the present disclosure include methods and systems for the automated commissioning of a network of electronic devices. The locations of large systems of installed electronic devices equipped with wireless communication modules, such as luminaires, light switches, and occupancy sensors, can be rapidly determined by using inter-device distance measurements to calculate the location coordinates of the devices. Increased confidence in the calculated location coordinates can be achieved by comparing the calculated values to an installation plan and assigning the IDs of the specific devices to the location coordinates in the installation plan.

System and method for automated commissioning of one or more networks of electronic devices

Systems, methods, and software for determining whether or not a monitored space is occupied by one or more humans and/or animals. In some embodiments, one or more radio-frequency (RF) receivers monitor(s) one or more RF frequencies for changes in received signal strength that may be due to changes in occupancy of the space being monitored. The received signal strength is analyzed using nonparametric online change-point detection analysis to determine change-points in the received signal(s). One or more statistical measures of the received signal(s), such as mean and variance, are used in conjunction with the change-point detection to determine a probability that the occupancy of the monitored space has changed. In some embodiments, additional sensors and/or machine learning can be used to enhance the performance of the disclosed occupancy-detection methodologies.
