A volume measurement apparatus comprises: a point group conversion part converting depth information from a depth sensor into point group data; a raw material heap detection part detecting a point group related to a raw material heap from the point group data, using repose angle information; and a raw material heap volume calculation part that calculates a volume of the raw material heap non-occlusion part based on the point group related to the raw material heap; estimates a volume of the raw material heap occlusion part in the raw material heap, using at least the point group related to the raw material heap; and calculates a volume of the raw material heap, which is a sum of the calculated volume of the raw material heap non-occlusion part and the estimated volume of the raw material heap occlusion part.

An object detection apparatus comprising: an input part configured to input video data, an extraction part configured to extract image data from the video data, and a determination part configured to determine whether or not the image data includes an object, wherein the determination part is configured to: set a plurality of regions in a learning image data such that the object appearing in the learning image data extracted from a learning video data captured in advance extends over at least the plurality of regions, assign a learning teach label to each of the regions set, and determine whether or not the image data includes the object by using a prediction model generated by utilizing the learning teach label assigned to each of the regions set.

In a sensor network system, sensor data having a high precision (high resolution) is collected, and congestion of a communication network and an apparatus for processing the sensor data is suppressed. A sensor node has a contribution degree calculator for calculating an influence that the detected sensor information exerts upon the entire system precision (resolution). A first communicating circuit transmits sensor information responding to a calculated contribution so that no congestion caused by transmitting too large a quantity of data all at once occurs.
