Abstract
To realize a warning signal generation system that can be realized at low cost by a simple configuration that is easy to maintain, recognizes an environment around a travelable vehicle or the like with high accuracy, and generates a warning signal that presents information indicating a possibility that the vehicle or the like becomes a dangerous situation based on a recognition result.SOLUTION: A warning signal generation system 1000 acquires a speed and a safe distance of an own vehicle estimated by a speed estimation processing unit 1, object tracking processing result data acquired by an object detection tracking processing unit 2, and a lane detected by an environment data analysis processing unit 3, using a video signal acquired by an imaging unit C1. Then, the warning signal generation system 1000 acquires (generates) a warning signal that presents information indicating possibility that the own vehicle becomes a dangerous situation by analyzing the data acquired as described above on a frame image.SELECTED DRAWING: Figure 1
