Method for determining an occupancy status of a parking bay and for determining the occupancy statuses of several parking bays along a street
The invention relates to a method for determining an occupancy status of a parking bay, wherein a vehicle is moved along a street segment with at least one parking bay and the vehicle has a distance sensor as well as a sensor for satellite-based location and time determination. Furthermore, static parking information on the position of the parking bays in a street segment and parking information on the parking bays are on hand. By means of distance and location data projected distance data are produced which each indicate a distance datum of the distance sensor to the next object in the sensor direction at a point of the street of the street segment at the parking bay. By means of these projected distance data a standard distance is ascertained. Subsequently, for each point of a parking bay the determination is made if this is unoccupied by comparing the distance datum with the standard distance plus a delta. An area of a parking bay is determined as one or several vacant parking spaces if the rounded-down quotient of the length of the adjoining contiguous unoccupied points to the length of an average parking space is 1 or greater.

SYSTEM AND METHOD FOR RESOURCE-DRIVEN DATAPOINT AGGREGATION OF LIDAR DATAPOINTS EXCHANGED BETWEEN LIDAR SENSOR AND HOST COMPUTING DEVICE AND APPLICATION OF SAME
A system and a method for performing exchange of lidar datapoints between a lidar sensor and a host computing device are provided. The lidar sensor stores a sensor payload size range, and the host computing device stores a host payload size range. When the lidar connection is initiated, the host computing device and the lidar sensor perform handshaking to determine an overlapping range between the host sensor payload size range and the sensor payload size range, and to negotiate an acceptable datapoint payload size based on the overlapping range. Once the handshaking is complete, the lidar connection may be performed using the acceptable data point payload size as a payload size thereof. Thus, the payload size is independent of a maximum transmission unit (MTU) of an Ethernet.
