To enable object determination based on radar data to be carried out highly accurately by using a machine learning model. In the present invention, radar data including pieces of information about reflection intensity and speed at each distance in each orientation is acquired; a radar detection image is generated in which, on the basis of the radar data, the pieces of information about the reflection intensity, the speed, and the distance corresponding to the position of pixels are stored in a plurality of channels of the pixels; the radar detection image is inputted to a machine learning model for image recognition learned so as to carry out object determination; and an object determination result outputted from the machine learning model is acquired. In particular, an object area is detected from radar data of an entire observation area, radar data of the object area is extracted from the radar data of the entire observation area, and a radar detection image of the object area is generated on the basis of the radar data of the object area.

    使用机器学习模型从而能够高精度地进行基于雷达数据的物体判别。获取包含各方位及各距离处的反射强度和速度的各信息的雷达数据,基于该雷达数据来生成雷达检测图像,该雷达检测图像在各像素的多个通道中分别保存有与该像素的位置对应的反射强度、速度及距离的各信息,将该雷达检测图像输入到为进行物体判别而进行了学习的图像识别用的机器学习模型,获取从该机器学习模型输出的物体判别结果。特别是,根据整个观测区的雷达数据来检测出物体区域,从整个观测区的雷达数据提取物体区域的雷达数据,基于该物体区域的雷达数据,来生成物体区域的雷达检测图像。
