A perception perceives a driving environment surrounding an ADV based on sensor data obtained from a variety of sensors. Based on the perception data received from the perception module, a planning module is to plan a trajectory for a current driving cycle to drive the ADV. In addition, the planning module determines a driving intent and one or more regions of interest (ROIs) surrounding the ADV based on the trajectory. The driving intent and the ROIs information is then provided to the perception module as a feedback. The perception module can then processing the sensor data from selective sensors to generate the perception data for a next driving cycle. The selected sensors may be determined and selected based on the driving intent and the ROIs, such that the sensor data of the unrelated sensors may be ignored to reduce the computation cost of the perception module.
