A bioinformation acquiring apparatus includes at least one processor and a memory configured to store a program to be executed in the processor. The processor acquires a waveform signal representing vibrations of a target, the vibrations resulting from heartbeats of the target; extracts provisional heartbeat timings from the acquired waveform signal based on a first time window; the provisional heartbeat timings indicating provisional values of heartbeat timings being timings at which the heartbeats of the target occur; acquires corrective peak timings from the acquired waveform signal based on a second time window having a shorter time length than the first time window, each of the corrective peak timings serving as a discrete correction unit for correction of the provisional heartbeat timings; corrects the extracted provisional heartbeat timings into definitive heartbeat timings based on the acquired corrective peak timings; and acquires bioinformation on the heartbeats of the target based on the corrected heartbeat timings.

A bioinformation acquiring apparatus includes at least one processor; and a memory configured to store a program to be executed in the processor. The processor acquires bioinformation in a chronological order; derives outlier level parameters, the outlier level parameter indicating a level of inclusion of outliers of the bioinformation in pieces of bioinformation acquired within a first duration; derives correction terms based on the bioinformation after removal of the outliers of the bioinformation from pieces of bioinformation acquired within a second duration that is longer than the first duration; selects one or both of a first correction procedure and a second correction procedure based on the outlier level parameters, as a correction procedure, the first correction procedure using the correction terms, the second correction procedure involving interpolation irrelevant to the correction terms; and corrects the outliers of the bioinformation within the first duration by the selected correction procedure.

A CAP detection device configured to acquire pulse wave data of a subject, derive a baseline of the data and an envelope of the baseline, identify a local maximum point of the envelope and determine, as CAP candidate points, a first local maximum point of the baseline before the local maximum point of the envelope and a second local maximum point of the baseline after the local maximum point, and identify, for each CAP candidate point, a third local maximum point of the baseline before the CAP candidate point and a local minimum point of the baseline between the CAP candidate point and the third local maximum point and detect the CAP candidate point as a CAP based on an evaluation value obtained from a difference between the CAP candidate point and the third local maximum point and a difference between the CAP candidate point and the local minimum point.

An autonomous mobile apparatus includes a driving unit, a memory including a map memory, and a processor. The processor is configured to estimate an apparatus location based on information from the driving unit and estimate the apparatus location based on information from other than the driving unit. The processor is configured to acquire a location of an object around the autonomous mobile apparatus, create an environment map based on the estimated apparatus location and the acquired object location, and store the environment map in the map memory. The processor is configured to use, at a time of tracking when the estimation of the apparatus location based on the information from other than the driving unit is enabled, the environment map that is in the map memory at a time of reference determined by a time of loss when the estimation of the apparatus location is not enabled.

Autonomous mobile apparatus and autonomous move method

An autonomous movement device includes an obstacle detector, a map creator, an obstacle canceller, and a router. The obstacle detector detects an obstacle. The map creator records information about the obstacle detected by the obstacle detector on an environment map. The obstacle canceller cancels the information about the obstacle recorded by the map creator from the environment map. The router sets a moving route based on the information recorded on the environment map.

Edges of layers are detected from an input image to create a boundary line candidate image that represents the detected edges. A luminance value of the input image is differentiated to create a luminance value-differentiated image that represents luminance gradient of the layers. An evaluation score image is created which is obtained by weighting calculation at an optimum ratio between a boundary line position probability image and the luminance value-differentiated image. The boundary line position probability image is obtained from the boundary line candidate image and an existence probability image that represents existence of a boundary line to be extracted. A route having the highest total evaluation score is extracted as the boundary line. According to such an image processing apparatus and image processing method, boundary lines of layers can be extracted with a high degree of accuracy from a captured image of a target object composed of a plurality of layers.

Image processing apparatus, image processing method, and image processing program

The movement direction-and-speed determiner of an autonomous movement device determines the direction and speed for an autonomous movement based on information on the plurality of picked-up images by an image picker. A feature point obtainer obtains a feature point from the picked-up image by the image picker. A map memory stores the position of the obtained feature point by the feature point obtainer. A corresponding feature-point number obtainer obtains the number of correspondences between the obtained feature point by the feature point obtainer and the feature point having the position stored in the map memory. When the obtained number of corresponding feature points by the corresponding feature-point number obtainer is equal to or smaller than a threshold, in order to increase the number of corresponding feature points, a moving direction-and-speed changer changes the moving direction and speed to those determined by the movement direction-and-speed determiner.
