  "textContent": "A measurement apparatus repeatedly executes measurement determination of whether measurement of a wall object has succeeded. If the wall-object measurement has succeeded, the measurement apparatus calculates an instantaneous wall-distance value indicative of a distance of the wall object from the own object. Otherwise, if the wall-object measurement has not succeeded, the measurement apparatus executes first extrapolation of an additional instantaneous wall-distance value. The measurement apparatus prevents an additional execution of the first extrapolation upon determination that the frequency of continuously repeated executions of the first extrapolation is not less than a prevention threshold frequency. The measurement apparatus sets, if the result of the measurement determination is correct, a correct-state threshold as the prevention threshold frequency, and sets, if the result of the measurement determination is incorrect, an incorrect-state threshold as the prevention threshold frequency; the incorrect-state threshold is smaller than the correct-state threshold.",
