Abstract

The disclosure comprises a vehicle-mounted sensing system and a vehicle with the vehicle-mounted sensing system. The vehicle-mounted sensing system comprises: a plurality of sensor assemblies provided at the specific positions of a vehicle to enable sensing of a specific range around the vehicle, the specific range depending on the purpose of sensing and/or characteristics of the sensor assemblies; and a processing unit configured to process sensing data from the plurality of sensor assemblies to generate sensing results; wherein the sensor assemblies are three-dimensional sensing assemblies. With the vehicle-mounted sensing assembly according to the disclosure, a three-dimensional environment around the vehicle can be accurately sensed, and the sensing results can be applied to operations such as parking.

First claim

1 . A vehicle-mounted sensing system, comprising:
a plurality of sensor assemblies provided at the specific positions of a vehicle to enable sensing of a specific range around the vehicle, the specific range depending on a purpose of the sensing and/or characteristics of the sensor assemblies; and a processing unit configured to process sensing data from the plurality of sensor assemblies to generate sensing results; wherein the sensor assemblies are three-dimensional sensing assemblies.

2 . The system according to claim 1 , wherein
the three-dimensional sensing assembly is a laser radar assembly, which comprises an emitting apparatus and a receiving apparatus, the emitting apparatus being a vertical-cavity surface-emitting laser (VCSEL), and the receiving apparatus being a single photon avalanche diode (SPAD).

3 . The system according to claim 1 , wherein
arrangement positions of the plurality of sensor assemblies include one or more of the following: a front bumper, a rear bumper, a license plate lamp shell, a trunk lid switch, a vehicle roof, and a vehicle door.

4 . The system according to claim 3 , wherein
the arrangement positions are determined on the basis of fields of view (FOVs) of the plurality of sensor assemblies.

5 . The system according to claim 4 , wherein the FOV is at least one of 180°, 120°, 90° and 60°.

6 . The system according to claim 1 , wherein the sensing results are three-dimensional scene information.

7 . The system according to claim 1 , wherein the processing unit is further configured to implement a direct time of flight (dToF) method or an indirect time of flight (iToF) method.

8 . The system according to claim 1 , wherein the sensing data is in the form of point cloud data.

9 . The system according to claim 8 , wherein the point cloud data is processed by a point cloud processing module on the processing unit or a point cloud processing unit independent of the processing unit.

10 . The system according to claim 1 , wherein the specific range is 360 degrees, and the purpose of the sensing is any one or both of forward detection and front angle blind zone compensation.

11 . The system according to claim 1 , further comprising:
a control unit configured to generate control signals for the plurality of sensor assemblies.

12 . A vehicle, comprising a vehicle-mounted sensing system, wherein the system comprises:
a plurality of sensor assemblies provided at the specific positions of a vehicle to enable sensing of a specific range around the vehicle, the specific range depending on a purpose of the sensing and/or characteristics of the sensor assemblies; and a processing unit configured to process sensing data from the plurality of sensor assemblies to generate sensing results; wherein the sensor assemblies are three-dimensional sensing assemblies.
