Methods and systems for detection of reflective markers at long range
Example methods and systems for detecting reflective markers at long range are provided. An example method includes receiving laser data collected from successive scans of an environment of a vehicle. The method also includes determining a respective size of the one or more objects based on the laser data collected from respective successive scans. The method may further include determining, by a computing device and based at least in part on the respective size of the one or more objects for the respective successive scans, an object that exhibits a change in size as a function of distance from the vehicle. The method may also include determining that the object is representative of a reflective marker. In one example, a computing device may use the detection of one reflective marker to help detect subsequent reflective markers that may be in a similar position.
