A scanner and a method for controlling the scanner for a Lidar system are provided. The method comprises: producing a trigger signal by a positional sensor of the scanner; generating a single drive signal comprising a first component at a first frequency and a second component at a second frequency, the first component and the second component are superposed with a fixed phase relationship with aid of the trigger signal; transmitting the single drive signal to the scanner, and the scanner has resonant responses at the first frequency; and actuating the scanner to move in a first periodic motion at the first frequency about a first axis, and move in a second periodic motion at the second frequency about a second axis.

Scanner control for Lidar systems

The present invention provides a detection device and a method for adjusting a parameter thereof. The device includes a real-time collection module, configured to collect and obtain environment information in real time; a real-time location information obtaining module, configured to obtain location information in real time; a parameter determining module, configured to determine a value of a target parameter of the detection device based on at least either the obtained environment information or the obtained location information; and a parameter adjustment module, configured to adjust the parameter of the detection device in real time based on the determined value of the target parameter. Based on the present invention, the parameter of the detection device can be adjusted in real time, and the detection device can adapt to diversified road conditions and improve detection accuracy.
