A quantum method that uses the Mz quantum circuit that receives a given single chaotic value to generate strong quantum key stream of three keys. The method includes encrypting a quantum plain color image; applying set of CNOT gates between qubits of a quantum image and qubits of a quantum key to obtain a quantum encrypted image; generating a new quantum key, applying additional set of CNOT gates between the qubits the quantum color image, and the corresponding qubits of the quantum key as target qubits; performing a quantum plain scrambling (QPS) operation; and applying set of CNOT gates; and obtaining, by the quantum circuit, a quantum ciphered image.

A method and device for amending a reference path associated with a vehicle are disclosed. The method includes: (i) acquiring road segment data and reference path data, the reference path data having a plurality of anchor points defining the reference path along the road segment, (ii) using the road segment data and the reference path data to determine a safe deviation interval for each one of the plurality of anchor points, a given safe deviation interval for a given anchor point being indicative of an acceptable deviation of the vehicle from the reference path; and (iii) using the safe deviation intervals to determine an amended path for the vehicle instead of the reference path, such that by following the amended path the vehicle falls within the constraints of the road segment.

Described herein are techniques for facilitating communications between vehicles within a platoon while minimizing latency. In some embodiments, such techniques may be performed by a lead vehicle and may comprise obtaining, from one or more sensors, sensor information pertaining to an environment in which the lead vehicle is located and generating, from the sensor information, driving instructions to be executed by a platoon of vehicles. The techniques may further comprise identifying, within the platoon of vehicles, a plurality of separate groups of vehicles and transmitting the generated driving instructions to a platooning platform via a long-range communication channel such that the driving instructions are relayed to each of the plurality of separate groups of vehicles. The techniques may further comprise transmitting the generated driving instructions to at least one additional vehicle of the platoon of vehicles via a short-range communication channel.

The invention discloses a method, device and equipment for determining the transverse distance of a target vehicle and a medium, and belongs to the field of automatic driving, and the method comprises the steps: obtaining the target driving parameters of the target vehicle and obtaining the driving parameters of the vehicle when the target vehicle exists in front of a road on which the vehicle travels; performing risk assessment according to the target driving parameter and the self-driving parameter to obtain an assessment result; if the assessment result is that the collision risk exists, the transverse distance of the target vehicle is determined based on the target driving parameters and the driving parameters of the vehicle, and the transverse distance is the distance between the vehicle body edge of the target vehicle and the left and right channel sidelines of the road. According to the method, the transverse distance detection is triggered only when the two vehicles have the collision risk, frequent calculation of non-threat targets is avoided, calculation power resource occupation is reduced, the resource utilization rate is improved, response delay of the vehicle control end due to frequent data input can be avoided, unnecessary forced movement is reduced, and the driving smoothness is improved.

A signal transmission method and an apparatus can be used in the field of autonomous driving, intelligent driving, or self driving. In embodiments of this application, a total available frequency band of a detection apparatus includes N frequency bands with same bandwidths, the N frequency bands respectively correspond to N orientation ranges, and N is an integer greater than 1. When the detection apparatus transmits a signal, a first available frequency band of the signal is determined based on an orientation of the detection apparatus, the signal is transmitted on the first available frequency band, and the first available frequency band is one of the N frequency bands. In this way, detection apparatuses in different orientation ranges use different frequency bands to transmit signals. In this way, selection of a transmission frequency band of a detection apparatus can be standardized, and interference between detection apparatuses can be reduced.
