器件型号:AWR1843BOOST

工具与软件:

您好!

我正在使用" automatically_parking_18xx "用于从检索数据的代码 AWR1843BOOST .
代码输出以下结构:

Header Structure (MmwDemo_output_message_header):
    Description: This structure serves as metadata for the radar data packet.
    Attributes:
        platform: Identifier for the platform on which the radar is operating.
        magicWord: A 64-bit magic word used for frame synchronization.
        numDetectedObj: Number of detected objects in the frame.
        version: Information about the software development kit (SDK) version.
        totalPacketLen: Total length of the packet.
        timeCpuCycles: Timestamp represented in CPU cycles.
        frameNumber: Frame number.
        subFrameNumber: Subframe number within the frame.
        numTLVs: Number of TLV (Type-Length-Value) elements present in the packet.
        
Generalised : TLV Element Structure (MmwDemo_output_message_tl):
    Description: Represents a TLV element within the radar data packet.
    Attributes:
        type: Type of data contained in the TLV element (e.g., detected points, side info).
        length: Length of the TLV data in bytes.
        
1.  Detected Points (MMWDEMO_OUTPUT_MSG_DETECTED_POINTS):
        Data Structure: DPIF_PointCloudCartesian
            Represents a point in a 3D Cartesian coordinate system.
            Attributes:
                x: X coordinate of the point.
                y: Y coordinate of the point.
                z: Z coordinate of the point.
                velocity: Velocity associated with the point.
2.  Detected Points Side Info (MMWDEMO_OUTPUT_MSG_DETECTED_POINTS_SIDE_INFO):
        Data Structure: DPIF_PointCloudSideInfo
            Contains side information associated with a point cloud.
            Attributes:
                snr: Signal-to-noise ratio (SNR) of the detected object.
                noise: Noise level associated with the detected object.
3.  Range Profile (MMWDEMO_OUTPUT_MSG_RANGE_PROFILE):
        Data Structure: uint16_t[]
            Array of uint16_t representing the intensity of the radar return signal at different range bins.
4.   Noise Profile (MMWDEMO_OUTPUT_MSG_NOISE_PROFILE):
        Data Structure: uint16_t[]
            Array of uint16_t representing the noise level at different range bins.
5.  Azimuth Static Heat Map (MMWDEMO_OUTPUT_MSG_AZIMUT_STATIC_HEAT_MAP):
        Data Structure: cmplx16ImRe_t[]
            Array of cmplx16ImRe_t structures representing complex values representing the distribution of objects in the azimuth domain.
6.   Range Doppler Heat Map (MMWDEMO_OUTPUT_MSG_RANGE_DOPPLER_HEAT_MAP):
        Data Structure: uint16_t[][]
            2D array of uint16_t representing intensity values representing the distribution of objects in the range-doppler domain.
7.   Stats (MMWDEMO_OUTPUT_MSG_STATS):
        Data Structure: MmwDemo_output_message_stats
            Structure containing statistics information related to radar operation.
8.   Temperature Stats (MMWDEMO_OUTPUT_MSG_TEMPERATURE_STATS):
        Data Structure: MmwDemo_temperatureStats
            Structure containing temperature statistics, such as sensor temperature

我的目标是将雷达用于紧急制动系统。 如果检测到前方有物体、汽车应停止行驶。 但是、MMWDEMO_OUTPUT_MSG_DETECTED_POINTS 中的数据并不表示我是在接收对象的质心还是曲面。 此外、它不提供物体的宽度、这是创建边界框和确定物体是否在汽车路径中所必需的。

您能否说明 MMWDEMO_OUTPUT_MSG_DETECTED_POINTS 代表什么?
此外、  需要哪些结构来确定紧急制动系统的物体的宽度和位置(如果需要)?

提前感谢您。

    您好!

    使用雷达传感器时、由于角分辨率不足、无法测量物体的宽度。

    谢谢你

    那么使用多个雷达传感器是可行的吗?

    此外、 MMWDEMO_OUTPUT_MSG_DETECTED_POINTS 能说明什么? 它们是哪些点? 或什么?

    即使有多个传感器也可能无法实现。

    检测点将是传感器接收到的最强反射。 没有关于反射在表面中心或一侧位置的信息。

    谢谢你
