Abstract: This disclosure relates generally to methods and systems for unobtrusive and automated detection of frequencies of spatially located distinct parts of a machine. Location of vibration and detection of vibration frequency of each vibrating part in a machine is critical for routine monitoring and fault detection in the machine. Current solutions use either high frames per second (fps) industrial grade camera or stroboscopes tuned at one particular frequency. Manual stroboscopes require manual intervention for objects moving at different speeds with high convergence time. Point-lasers need prior knowledge of exact location of faults. Also Point-by-point scanning of a large machine body is time consuming. In the present disclosure, a movement detector such as RADAR enables detecting all vibration frequencies that also serve to reduce the search space of a stroboscope configured to start strobing at each detected vibration frequency to enable mapping of each vibration frequency to a corresponding vibrating part.

Abstract: An illumination module and a depth camera on a near-eye-display (NED) device used for depth tracking may be subject to strict power consumption budgets. To reduce power consumption of depth tracking, the illumination power of the illumination module is controllably varied. Such variation entails using a previous frame, or previously recorded data, to inform the illumination power used to generate a current frame. Once the NED determines the next minimum illumination power, the illumination module activates at that power level. The illumination module emits electromagnetic (EM) radiation (e.g. IR light), the EM radiation reflects off surfaces in the scene, and the reflected light is captured by the depth camera. The method repeats for subsequent frames, using contextual information from each of the previous frames to dynamically control the illumination power. Thus, the method reduces the overall power consumption of the depth camera assembly of the NED to a minimum level.

Abstract: Described is a method for processing image data to determine if a portion of the image data is affected due to sunlight. In some implementations, image data is sent to an image data store and camera parameters are sent to a radiance detection service. The radiance detection service, upon receiving the camera parameters, retrieves the image data, converts the image data to gray-scale and processes the image data based on the camera parameters to determine a radiance value for the camera. The radiance value may be compared to a baseline radiance value to determine if sunlight is represented in the image data. In some implementations, a baseline model may be developed for the camera and used to cancel out any pixels of the image data that are overexposed under normal or baseline conditions. Likewise, a foreground model may be generated to detect any objects in the image data for which corresponding pixel values should not be considered for determining if sunlight is represented in the image data.
