Embodiments of the present invention provide an unmanned aerial vehicle obstacle avoidance method and apparatus, an unmanned aerial vehicle, a remote control device and a storage medium. The method comprises: obtaining a real-time environment image captured by an image photographing device of an unmanned aerial vehicle; and superposing a first mark in a first image area of the real-time environment image, and superposing a second mark in a second image area of the real-time environment image, wherein the first mark and the second mark are used for indicating that an environment space corresponding to the first image area and an environment space corresponding to the second image area have different obstacle avoidance costs, and the obstacle avoidance costs are associated with safety, the electric quantity consumed by obstacle avoidance and/or the length of an obstacle avoidance path. By adopting the present invention, different marks are superposed in different image areas in the real-time environment image, and environment spaces corresponding to the different image areas have different obstacle avoidance costs.
A detection apparatus may include a light source to emit a light pulse sequence, a first scanner and a second scanner disposed in an optical path of the light pulse sequence to change propagation direction of the light pulse sequence. The first scanner alone may be capable of causing an outgoing light beam to scan along a first path, and the second scanner alone may be capable of causing the outgoing light beam to scan along a second path. The first scanner may include a reflector and a first driver; and the second scanner may include a reflective structure and a second driver, the reflective structure including at least two reflective surfaces. The second driver may drive the reflective structure to rotate so that the at least two reflective surfaces are rotated sequentially onto the optical path of the light pulse sequence.
A control method, comprising: acquiring distribution information of point clouds (110); and determining whether the point cloud row distribution of the point clouds is along a second direction, and if the point cloud row distribution of the point clouds deviates from the second direction, controlling first reflecting modules (20, 102, and 1221) to adjust from a current attitude to a target attitude, so as to correct the point cloud row distribution to the second direction (120). The control method can adjust the point cloud distribution of detection devices (100 and 122), and when the point cloud row distribution deviates and affects the uniformity of the point cloud distribution, the point cloud row distribution can be corrected to a suitable direction by controlling the attitude of a scanning module to change, so as to generate a desired point cloud distribution.
