NEC has published an optical interpretation technology

NEC has published an optical analysis technology that can be used to detect the species or fertility of humans or ships on vast oceans, or to remote mountain woodlands or large-scale agricultural land that are inaccessible to humans, without the effects of weather conditions.

In recent years, the Light analysis technology has been developed to analyze the light source structure containing the reflected wavelength of object (spectral spectrum), and it does grasp the material and state of objects which can not be recognized by the naked eye, and applies it to the vast land and sea information analysis. The technology is also expected to be used in the future in areas such as tsunami victims and ship rescues, large-scale agricultural or biodiversity conservation, ecological observation, or resource surveys.

The spectrum observation is currently carried out with the spectrum camera of the flight equipment, however, it is difficult to obtain the correct information in the condition of cloudy or sunny weather in the current equipment. Furthermore, in order to observe the current equipment, it is necessary to set up a basic object (such as a full whiteboard) with known light source structure around the observation destination in advance, and there are still many limitations in its application.

The development of new technologies, can be unaffected by the weather conditions, from the equipment observed in the spectrum, stable and accurate estimation of material materials and state information (surface reflectance). Through this technology, it is possible to overcome the current difficulties in the cloudy state of the plant species can not be correctly judged, or at the time of the salvage of the victims and ships can not be accurately detected bottlenecks. In addition, because this technique is to estimate the surface reflectivity of the object with the spectrum of the spectrometer observed by the equipment, it is possible to solve the problem that the existing equipment is difficult to set the standard object in the mountain forest, and it cannot carry out the biological observation and resource exploration in the area.

The technical features of this publication are as follows:

1. Any weather pattern can be observed

This technology is equipped with the development of NEC, the Global initiative can simulate weather patterns such as sunny and cloudy days (300nm~4000nm intensity of each wavelength) (called solar modules), which can be detected without the influence of weather changes, and can reduce the error value by 70% compared with the current observation technique. The precision of observation of object intelligence is excellent.

2. All terrain on the surface can be observed

Combining the solar modules developed by NEC with the theory of color constancy calculation, the surface reflectivity of the observed objects is estimated only by the spectral data of the spectrometer observed by the equipment. This technique not only solves the inconvenience of having to set up a basic object beforehand, it can be easily observed in a corner of the vast land, or in a terrain place where the human force is difficult to penetrate.

NEC will continue the research and development of this technology and will further apply the research findings to public safety areas such as disaster prevention or large-range surveillance, as well as assisting in new ventures such as agricultural development, geo-environmental maintenance, and resource surveys.
