Title:
OBJECT RECOGNITION DEVICE, OBJECT RECOGNITION METHOD AND AUTOMATIC DRIVING SYSTEM
Document Type and Number:
Japanese Patent JP2017227580
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an object recognition device that reduces a risk of misrecognition on an object by improving recognition precision for the object, according to the present invention.SOLUTION: An object recognition device 4 according to the present invention comprises: a data reception part 5 which generates and outputs observation data for each sensor according to detection data on an object in the circumference of an automobile from a plurality of sensors 1, 2; a correlation processing part 6 which finds correlation data showing correspondence relation between the observation data and the object data in a last processing period on the basis of a correlation reference value, and outputs the observation data and the correlation data; and an update processing part 7 which updates a status vector included in the object data in the last processing period on the basis of the correlation data, also updates the latest correlation data as observation data corresponding to the latest one of the observation data by including it in the object data for each sensor, and outputs the updated object data. The correlation processing part 6 finds the correlation reference value preferentially using the latest correlation data of the same sensor with the observation data in the current processing period.SELECTED DRAWING: Figure 1
