Problems solved by technology
[0005] However, although unmanned vehicles can predict the lanes of surrounding obstacles in the future through existing technologies, they cannot predict the trajectory of surrounding obstacles in the future, which leads to unmanned vehicles predicting The surrounding obstacles may still collide with the surrounding obstacles in the next lane, that is, the smooth driving of the unmanned vehicle cannot be guaranteed through the existing technology

The invention discloses an obstacle trajectory prediction method and device, and unmanned equipment, and the unmanned equipment can predict the image data, collected after a set time, of an obstacle based on the determined environment feature data, and can predict the position of the obstacle in the future based on the position of the image of the obstacle in a prediction image. Along with the continuous increase of the number of the obtained prediction images; based on the position of the image of the obstacle in each prediction image, the motion trail of the obstacle in a future period of time can be finally obtained, so that the unmanned equipment can avoid the obstacle in time based on the predicted motion trail of the obstacle, and the advancing safety of the unmanned equipment is further ensured.
Description
technical field [0001] This specification relates to the field of unmanned driving equipment, in particular to a method and device for obstacle track prediction. Background technique [0002] At present, unmanned vehicles, robots and other unmanned equipment have been widely used in many fields. With the continuous improvement of the level of science and technology, unmanned driving equipment will be further developed in various fields, thus bringing more convenience to people's real life. [0003] In order to ensure the smooth driving of the unmanned equipment, it is necessary to predict the driving conditions of the obstacles contained in the surrounding environment of the unmanned equipment, so that the unmanned Avoid obstacles in time according to driving conditions. [0004] Taking unmanned vehicles as an example, in the existing technology, unmanned vehicles can collect sensing data through sensors such as lidar and infrared, and predict the obstacles around the unma...
