摘要： A pattern discriminator receives scanning data obtained by raster scanning objects within predefined window regions with a photoelectric converter, converts the scanned data into pixel binary data by using a threshold value dependent upon the scanning position and window region and evaluates the binary data in accordance with predetermined criteria to produce an output signal indicative of the evaluation. Data specifying the shapes of the desired window regions approximated by polygons is obtained by specifying the apexes of the polygons and a programmed CPU computes the coordinates of each picture element or pixel on the lines connecting adjacent apexes along each window region perimeter. A memory stores the apex and coordinate data which defines the starting and ending points of each window region. Polygonal masks within each window and sub-mask polygonal window regions within each mask can be defined in a similar manner. A shifting detector and position corrector detects the amount of any positional shift of an object being scanned in relation to the position of a previously scanned reference object, and shifts the locations of the defined window regions by the amount of the positioned shift detected.

摘要： In order to provide an integral whole unit for continuously measuring the quantity of heat needed to melt snow lying on a road, and prevent freezing of the road; and for controlling a supply of heat to the road for melting the snow lying on the road and for preventing the freezing of the road, it uses a road-simulated device. The road-simulated device is put outdoors while it is snowing, and it is heated and kept at a temperature of -0.degree. C., thus keeping the road-simulated surface free of snows, and preventing the freezing of the road-simulated surface. In this condition the thermal energy required to keep the simulated road surface unfrozen is determined, and every control variable is determined on the basis of this so determined thermal energy.
