20210108925 | REFINING AN ECOLOGICAL NICHE MODEL - Refining an ecological niche model (ENM) associated with a geospatial location includes developing a fluid dynamics model based on measurements generated by a device deployed into fluid flows of the geospatial location. The measurements include temperature and velocity field, depth and particle transport measurements. The refining further includes refining and running the fluid dynamics model using measurements regenerated from the device being redeployed into the fluid flows to produce an output. This output is descriptive of fluid dynamics at the geospatial location and input into the ENM. The ENM is run to produce a baseline ENM output descriptive of a probability of a species existing at the geospatial location. In addition, the ENM is run with a limnologic modification to produce a predictive ENM output descriptive of a predictive probability of the species existing at the geospatial location that is comparable to the baseline ENM output. | 2021-04-15 |
20210108926 | SMART VEHICLE - Smart car operations are detailed including capturing a point cloud from a vehicle street view and converting the point cloud to a 3D model; applying a trained neural network to detect street signs, cross walks, obstacles, or bike lanes; and updating a high definition (HD) map with the neural network output. | 2021-04-15 |
20210108927 | REAL-TIME UPDATES TO MAPS FOR AUTONOMOUS NAVIGATION - Presented herein are techniques for updating detailed maps used to navigate an autonomous vehicle. The techniques include determining that a vehicle has come within a predetermined range of a road side unit, establishing a communication link with the vehicle, receiving, from the vehicle, data sufficient to identify a vehicle type of the vehicle, based on the vehicle type, selecting a map, stored by the road side unit, for the vehicle, sending a query to a neighbor road side unit seeking data to augment the map, in response to the query, receiving the data to augment the map from the neighbor road side unit, updating the map based on the data to augment the map to obtain an updated map, and sending at least a aspects of the updated map to the vehicle. | 2021-04-15 |
20210108928 | SYSTEMS AND METHODS FOR ROUTE SEARCHING - The present disclosure relates to systems and methods for searching for a route. The systems may perform the methods to obtain route information of a first route; encode the route information of the first route into a first code based on a target model; access a target database in at least one storage medium, wherein the target database includes a plurality of candidate codes encoded through the target model from a plurality of candidate routes; identify, from the plurality of candidate codes, a second code based on the first code, the second code being associated with at least one second route; and send information associated with the at least one second route to a receiving device. | 2021-04-15 |
20210108929 | DYNAMIC SELECTION OF AUTONOMOUS VEHICLE STOPPING POINTS - Disclosed are embodiments for adjusting a vehicle stopping point. The vehicle stopping point is a point between a route of the vehicle and a second route. in some embodiments, an adjustment to the stopping point is determined based on ranking secondary routes that are adjusted based on the adjusted vehicle stopping point. Tanking of the secondary routes is based, in sonic embodiments, on a score of segment(s) included in the secondary routes. In some cases, the ranking of the segments considers safety information associated with each of the segments. | 2021-04-15 |
20210108930 | METHOD AND APPARATUS FOR RECOMMENDING A TRAVEL PLAN, DEVICE AND STORAGE MEDIUM - The present disclosure provides a method and an apparatus for recommending a travel plan, a device and a storage medium, and relates to the field of computer technology. A query request sent by a terminal device for a travel plan is received, where the query request includes travel information. At least one candidate mixed travel plan is obtained from a travel plan database according to the travel information. A real-time travel cost parameter of the at least one candidate mixed travel plan is obtained and travel cost information of the at least one candidate mixed travel plan is obtained according to the travel cost parameter. An optimum mixed travel plan is selected from the at least one candidate mixed travel plan according to the travel cost information and sent to the terminal device. Candidate mixed travel plans are stored in the travel plan database. | 2021-04-15 |
