The present disclosure relates to the technical field of remote driving, and provides a data transmission method and device for a remote driving terminal of an unmanned vehicle. The method includes: when the unmanned vehicle enters the remote driving mode, turn on the camera device to collect video images of the surrounding environment of the unmanned vehicle; detect the current network bandwidth of the unmanned vehicle in real time; when the detected network bandwidth is greater than or equal to When the threshold is preset, the collected video image of the surrounding environment is transmitted to the remote driving terminal of the unmanned vehicle, so that the remote driving terminal displays the video image of the surrounding environment; when the detected network bandwidth is less than the preset threshold, the surrounding environment is stopped. The transmission of the video image of the environment, based on the collected video image, calculates the text information of the surrounding environment associated with the video image, and transmits the text information to the remote driving terminal; the remote driving terminal simulates the image of the surrounding environment of the vehicle based on the text information, And display the simulated image. The present disclosure improves the safety of remote driving.
Description
technical field [0001] The present disclosure relates to the technical field of remote driving, and in particular to a data transmission method, device, computer equipment and storage medium for a remote driving terminal of an unmanned vehicle. Background technique [0002] Remote driving is an integrated application of intelligent driving and 4G / 5G network. Remote driving technology transmits the perception data of the car to the cloud controller through network communication, and the human driver remotely controls it. If the underlying automatic driving system inside the car encounters problems, this technology will allow the remote operator to take over the vehicle. Efficiently solves what is known in the industry as the "edge" of the machine. [0003] At present, the control of the vehicle by the remote driving terminal mainly depends on the video images collected by the camera installed on the vehicle, and the transmission of video images mainly depends on the network ...
