Disclosed are a path control method, a path planning method, a first device, a second device, and a computer storage medium. The method includes: collecting and obtaining environment image data of an environment where a first device is located; sending the environment image data to a second device, such that the second device obtains a first movement trajectory for controlling the first device to move based on the environmental image data; receiving the first movement trajectory sent by the second device; and controlling the first device to move based on the first movement trajectory. The technical effect of improving the sensitivity of a first device in avoiding an obstacle during movement is achieved.
