Title:
METHOD AND DEVICE FOR GENERATING TRAVELLING ENVIRONMENT ABSTRACT IMAGE
Document Type and Number:
WIPO Patent Application WO/2016/157277
Kind Code:
A1
Abstract:
Conventionally, in evaluation of image processing logics for advanced driving assistance systems using vehicle-mounted cameras, it is necessary to actually drive vehicles to manually photograph a large number of evaluation images under different travelling environment conditions by using human wave tactics, and evaluate the images. Thus, verification man-hours are high. To reduce the man-hours is a significant problem. The present invention comprises: an abstract scene generating means that generates abstract scenes on the basis of travelling environment information from images taken by a vehicle-mounted camera; a travelling condition changing means that internally performs automatic generation of abstract scenes for different travelling environment conditions; an abstract scene accumulating means that stores the generated abstract scenes in a format that allows reuse of the generated abstract scenes; and a scene condition matrix generating means that can check the entire collection status of scenes required for evaluation of image recognition logics, so that evaluation scenes required for evaluation of image recognition logics for a vehicle-mounted camera can be collected efficiently. Further, since the abstract scenes can be used as input images in a driving simulator, scenes in which a driver cannot drive well can be efficiently generated, for example. According to the present invention, since abstract scenes of different travelling environment conditions can be automatically generated on the basis of images taken by a vehicle-mounted camera, the man-hours can be reduced for developing image recognition logics for a vehicle-mounted camera or for creating input scenes for a driving simulator.
