Abstract
A radar device that facilitates external processing device data usage is disclosed. In one example, raw data immediately after a reception signal from a reception antenna is sampled at a predetermined period and subjected to A/D conversion and is output in a first output data format. Point cloud data generated by executing a predetermined signal process on the raw data is output in a second output data format, and data of an object recognition result obtained by executing an object recognition process on the point cloud data is output in a third output data format. In one example, the raw data is output in the first output data format and/or the point cloud data is output in the second output data format.
Claims20
A radar device comprising:
- reception circuitry configured to receive a reception signal from a reception antenna, sample the reception signal for predetermined periods to provide a sampled signal, and subject the sampled signal to analog-to-digital (A/D) conversion for outputting data in a first output data format that includes raw data of the reception signal, wherein the data in the first output data format is provided to an output configured for access by an external processing device, and is independently accessible for use by the external processing device without requiring generation of point cloud data;
- transform circuitry configured to receive the data in the first output data format from the reception circuitry, to generate point cloud data from the raw data, and to output data in a second output data format;
- and
- object recognition circuitry configured to receive the output of the transform circuitry in the second output data format, perform object recognition on the point cloud data, and to output data in a third output data format based upon the object recognition performed on the point cloud data.
A data output method for a radar device comprising:
- receiving, by reception circuitry, a reception signal from a reception antenna, sampling the reception signal for predetermined periods to provide a sampled signal, and subjecting the sampled signal to analog-to-digital (A/D) conversion for outputting data in a first output data format that includes raw data of the reception signal, wherein the data in the first output data format is provided to an output configured for access by an external processing device, and is independently accessible for use by the external processing device without requiring generation of point cloud data;
- receiving, by transform circuitry, the data in the first output data format from the reception circuitry, generating point cloud data from the raw data, and outputting, by the transform circuitry, data in a second output data format;
- and
- receiving the output of the transform circuitry in the second output data, performing object recognition on the point cloud data, and outputting data in a third output data format based upon the object recognition performed on the point cloud data.
