  • Publication number: 20180003822
    Abstract: Disclosed are embodiments of environmental sensing devices and information acquiring methods applied to environmental sensing devices. In some embodiments, an environmental sensing device includes a camera sensor, a laser radar sensor that are integrated, and a control unit. The control unit is connected simultaneously to the camera sensor and the laser radar sensor. The control unit is used for simultaneously entering a trigger signal to the camera sensor and the laser radar sensor. The design of integrating the camera sensor and the laser radar sensor avoids the problems such as poor contact and noise generation that easily occur in a high-vibration and high-interference vehicle environment, and can precisely trigger the camera sensor and the laser radar sensor simultaneously, so as to obtain high-quality fused data, thereby improving the accuracy of environmental sensing. As a result, the camera sensor and the laser radar sensor have a consistent overlapping field of view.
