Title: Picture supervisory method
Inventor: YOKOTA MICHIYA
IPC: G06T1/00
Filed: 1990-06-14
Abstract: PURPOSE:To allow dispersion in the size of a characteristic area and dislocation by providing a dead zone area near a binarized level and supervisoring and judging a picture based on a binary code binarized beyond the dead zone area. CONSTITUTION:An output voltage value in a characteristic area part (w) to which work is executed is changed compared to the other part. The part is binarized at the prescribed binarized level Vth and a cross point between the binarized level Vth and an output voltage is set to be the dead zone area so as to remove it from an inspection area. Since a binarized signal from the object of normal supervisory is I(Vth), the area is between the area of I(Vth-DELTA) and the area of I(Vth+DELTA) and the characteristic area of the object of normal supervisory in the inspection area becomes the same as the area of I(Vth+DELTA). Thus, the dead zone area is provided near the code change point at the time of binarization and the picture is supervised and judged beyond the dead zone area. Thus, permissible dislocation and the variance of the size in the characteristic area of the object of supervisory are permitted and supervisory following the target of supervisory can be executed.

Abstract: PROBLEM TO BE SOLVED: To make accurately detectable only the reflection wave of an underground buried object by simplifying the configuration. SOLUTION: A pulse transmission signal from a transmission signal generation means is branched by a first branching means PD1, is given to a second branching means PD2 via a first directional coupler DC1 and a second attenuation means AT1, and is given to a second branching means PD2 through a second directional coupler DC2 and a second attenuation means AT2. By synthesizing the two signals, the synthesis signal is given to a single antenna. A reception signal from the antenna is branched by a second branching means PD2.  In one branch signal, the amount of attenuation is changed so that only a reflection wave p3 due to an object can be attenuated and is given to an attenuation means SBT from the second directional coupler DC2, the other branch signal of the second branch means PD2 is given to an attenuation means SBT through the first directional coupler DC1 from the first attenuation means AT1. Therefore, the output of the subtraction means SBT does not include a large- amplitude reflection wave p1 due to an impedance mismatching and a large- amplitude reflection wave p2 due to the ground surface.
