This specification discloses an obstacle avoidance method and device, a moveable object and a computer readable storage medium. The obstacle avoidance method includes: obtaining a depth value of a spot in an area containing an obstacle, the depth value representing a distance between the spot and the moveable object; judging, according to the depth value, whether an edge of the obstacle exists in the area; and if the edge of the obstacle exists in the area, determining a movement direction of the moveable object according to the edge, so as to avoid the obstacle. According to embodiments of the present invention, an obstacle grid map does not need to be established, and a movement track does not need to be predicted, achieving advantages of a small amount of calculation and high control accuracy.
