Abstract: In a three-dimensional scanner, a scanner main body calculates the position and direction of a depth sensor. The scanner main body also determines a movement candidate, which is a candidate for a position and direction to/in which the depth sensor is to be moved next. Then, the scanner main body acquires a feature within the movement candidate, which is the feature observable by the depth sensor from the movement candidate, and evaluates the stability of mapping performed from the movement candidate through use of the feature within the movement candidate. The scanner main body further presents at least any one of the moving direction or moving speed of the depth sensor to a user based on an evaluation result.

Abstract: A sensor data input device obtains a plurality of sensor data sequences, each indicating time-series sensor values generated by measuring a work of a working subject using a sensor. A class data generator determines a plurality of intervals obtained by temporally dividing each sensor data sequence based on the sensor values, determines classes of the intervals, each class indicating a type of temporal variations in the sensor values included in one of the intervals, and generates a plurality of first class data sequences for each sensor data sequence, each first class data sequence indicating the intervals and the classes of the sensor data sequence. A class data linker associates the corresponding intervals having an identical class with each other, among the plurality of first class data sequences. A determiner calculates characteristic values of the intervals associated with each other.

Abstract: Provided is an edit unit that checks, as time data, a designated time received in an input unit, against a map data DB to identify map data corresponding to the designated time. Upon the receipt of the designated time in the input unit, a map-data generating unit redoes the update of the map data, identified by the edit unit, using measurement data newly acquired after the designated time is received in the input unit.

Abstract: An object recognizer recognizes a position and an attitude of a target object based on data measured by a sensor. A safe distance calculator calculates a distance from the target object to a certain object which is other than an object manipulation apparatus and the target object. A manipulation controller controls the pickup device based on the position and the attitude of the target object, and based on the distance from the target object to the certain object. When there are a plurality of target objects to be selected by the object manipulation apparatus, the manipulation controller selects one of the target objects having distances to the certain object longer than a predetermined threshold, and manipulates the selected target object using the pickup device.
