  • Patent number: 11332146
    Abstract: An image captured by a far-infrared camera is analyzed to analyze a distribution of a road-surface temperature, and a course of a highest road-surface temperature is determined to be a traveling route. Further, automatic driving along the course of the highest road-surface temperature is performed. Furthermore, a state of the distribution of a road-surface temperature, and a direction of the course of the highest road-surface temperature are displayed on a display section, so that a user (a driver) recognizes them. For example, a state analyzer detects a candidate course travelable for a vehicle, the state analyzer detecting a plurality of the candidate courses, calculates an average value of a road-surface temperature of each of the plurality of the candidate courses, and determines the candidate course having a largest average value of a road-surface temperature to be a traveling route.

    Abstract: A first beam source radiates, as a reference beam, 905 nm of near infrared beam having a characteristic in which light tends not to be absorbed in water toward a leaf of a plant. A second beam source radiates, as a measuring beam, 1550 nm of near infrared beam having a characteristic in which light tends to be absorbed in water toward the leaf of the plant. A threshold level setter/water content index detector calculates a water content index of one leaf which is a total sum ? Ln (I905/I1550) of the reflection intensity ratio. A controller displays a graph representing the time-serial change of the water content contained in the plant from the start to the end of the measurement period on a UI screen of a monitor.

  • Patent number: 10984519
    Abstract: A method for evaluating the optical insertion loss of a mechanical splice joint of two optical fibers with a laser source includes, upon initiation by a user, automatically performing the steps of: checking for ambient light, estimating the level of noise by analyzing an area of a sensor that is not illuminated by external sources and setting a noise threshold, checking self-alignment by taking a foreground image of the joint with the laser source turned on and one with it turned off, subtracting the images to obtain a resultant image, setting all pixels with levels below the noise threshold to zero, selecting a region of interest of the joint, computing a centroid and a width of the resultant image based on the region of interest, estimating a tilt and if the tilt is above a certain threshold, compensating for the tilt, and processing the resultant image.

  • Patent number: 10977776
    Abstract: A method includes placing an imaging device in contact with a sample, irradiating the sample via an illuminator such that radiation scatters off of the structure, and providing the scattered radiation to a detector to generate a digital video signal. A processor then performs various operations including subtracting a sum of a black state value and a user-defined black level clamping value from the digital video signal to create subtracted image data, substituting negative values in the subtracted image data with a reference value to create modified image data, and amplifying the modified image data by a user-defined gain to create contrast enhanced image data.
