The invention provides a parking space detection device and a camera device used for monitoring a parking space and provided with radar. The parking space detection device comprises a shell, a radar, a radar beam wave structure and a camera. The radar is assembled in the radar mounting hole of the shell and comprises a transmitting surface; the radar beam wave structure comprises a main body part and a sunken part sunken inwards from the outer surface of the main body part, the main body part is fixed to the shell, the sunken part comprises a first opening and a second opening which are opposite, the radar corresponds to the sunken part, the emitting surface is located in the first opening, the second opening is away from the radar relative to the first opening, and the second opening is larger than the first opening. The inner surface of the sunken part comprises a beam wave surface extending from the first opening to the second opening, the beam wave surface comprises a first surface, the first surface is a curved surface bending and extending from the first opening to the second opening, and at least part of the first surface is located below the emission surface so as to limit the downward emission and echo receiving range of ultrasonic waves emitted by the radar. The camera is assembled in the shell.
本申请提供一种车位检测装置和用于监控车位的具有雷达的摄像机装置。车位检测装置包括壳体、雷达、雷达束波结构和摄像头。雷达组装于壳体的雷达安装孔,雷达包括发射面。雷达束波结构包括主体部和从主体部的外表面向内凹陷的凹陷部,主体部固定于壳体,凹陷部包括相对的第一开口和第二开口,雷达对应凹陷部设置,发射面位于第一开口,第二开口相对于第一开口远离雷达,且第二开口大于第一开口。凹陷部的内表面包括从第一开口向第二开口的方向延伸的束波面,束波面包括第一面,第一面为从第一开口向第二开口的方向弯曲延伸的曲面,且至少部分位于发射面的下方,以限制雷达发出的超声波向下发射和接收回波的范围。摄像头组装于壳体内。
