摘要： An object of the invention is to provide a method and an apparatus for producing land-surface image data, which can correct, with relatively high accuracy, cloud image data included in satellite image data into land-surface image data that would emerge in the absence of a cloud. Geostationary satellite image data 1 of a predetermined time at a production standard date is obtained, and a determination whether each pixel is a pixel reflecting a land surface 4 or a pixel reflecting a cloud 5 is made to set partial image data 6 and a missing region 7. Then, processing is repeated by sequentially adding another imaging date and time according to a predetermined priority until the missing region 7 is filled up with the pixel determined to be the pixel reflecting the land surface 4, thereby producing interpolated image data 9 to produce the land-surface image data. The pixel is determined to be the pixel reflecting the land surface 4 from a pixel value in the another imaging date and time that is determined to be data having a close temporal relevance in a relationship between a solar position and the predetermined time of the production standard date.

摘要： In a road image analyzing apparatus capable of obviously and rapidly distinguishing a road marking from a guardrail and capable of obtaining precise position information, a pre-processing unit defines sub-areas to main image data obtained by an image pickup unit, and an edge extracting unit extracts an edge component in each of the sub-areas. A linear line extracting unit analyzes the extracted edge component to extract a linear component, and a linear component analyzing unit extracts a continuous component from the linear component by using the linear component. A matching process unit performs a matching process between a vertex of the continuous component and auxiliary image data to obtain three-dimensional position information of each continuous component. An identifying unit identifies whether the continuous component is a road marking or a guardrail on the basis of height information of each continuous component included in the three-dimensional position information.

摘要： To provide measurement data on a real time basis from a laser measurement device mounted on an air vehicle to a ground station. The laser measurement unit sequentially outputs laser measurement data during a measurement period in which the air vehicle flies along a straight line flight fairway (32). The transmission unit desirably compresses the laser measurement data when the laser measurement data is accumulated to a file size while the air vehicle flies along straight line flight fairway (32), and transmits the laser measurement data to the ground station. The transmission units does not transmit the flight state data obtained by the GPS/IMU to the ground station on the straight line flight fairway (32), but transmits during a measurement suspended period in which the air vehicle flies along a turn fairway (34).
