Apparatus and method for automatically detecting an event in sensor data
First Claim
1. An apparatus for automatically detecting an event in sensor data, the apparatus comprising:
- a recording device for recording the sensor data;
a feature identification device for automatically identifying a prescribed set of features of the sensor data in the sensor data recorded;
a rating acquisition device for acquiring a respective rating for each of the features from the prescribed set of features, the respective rating relating to the event to be detected and is formed on a basis of a set of rating criteria, the set of rating criteria being based on at least one input interactively provided by a human expert for rating each of the features;
a detection device for automatically detecting the event to be detected by means of the features identified by said feature identification device on a basis of acquired ratings for the prescribed set of features, said detection device determining a probability value for each of a plurality of individual sections of the sensor data from the acquired ratings of the features;
a display device for showing the human expert a profile over time of the probability value of the individual sections of the sensor data; and
a threshold value acquisition device for acquiring, for at least one of the features from the set of features, a threshold value formed on a basis of the set of rating criteria and to exclude from a detection of the feature that is to be detected those excerpts from the sensor data recorded for which the at least one feature is below a prescribed threshold value.

Abstract
An apparatus automatically detects an event occurring in sensor data. The apparatus has a recording device which is configured to receive the sensor data, a feature identification device which is configured to automatically identify a predetermined number of features of the sensor data in the recorded sensor data, an evaluation processing device which is configured to acquire from the predetermined number of features, for each of the features, an evaluation which relates to the event to be detected and which is based on a set of evaluation criteria, and a detection device which is configured to automatically acquire the event to be detected by the features identified by the feature identification device, based on the detected evaluations for the predetermined number of features.

8. A method for automatically detecting an event in sensor data, which comprises the steps of:
-
recording of the sensor data; automatically identifying a prescribed set of features of the sensor data from recorded sensor data; modeling a respective rating for each of the features from the prescribed set of features, the respective rating relating to the event to be detected and is formed on a basis of a set of rating criteria, the set of rating criteria being based on at least one input interactively provided by a human expert for rating each of the features; acquiring a threshold value formed on a basis of the set of rating criteria for at least one of the features from the set of features, and excerpts from the recorded sensor data for which the at least one feature is below a prescribed threshold value are excluded from a detection of the feature that is to be detected; determining a probability value for each of a plurality of individual sections of the sensor data from acquired ratings of the features and showing the human expert a profile over time of the probability value of the individual sections of the sensor data; and automatically detecting the event to be detected by means of identified features on a basis of the acquired ratings for the prescribed set of features. - View Dependent Claims (9, 10, 11, 12, 13)
