This application relates to the field of gimbal technology, and more particularly to an environment-adaptive gimbal target tracking method, apparatus, gimbal, and storage medium. By establishing a target reference template and extracting initial features, a degradation risk distribution map is generated for each frame of image to quantify the risk of feature loss. After obtaining the target's current predicted position, a first deviation between the predicted position and the image's geometric center, and a second deviation between the predicted position and the lowest-risk position near the predicted position are calculated. Based on this, a gimbal control signal is generated to drive the gimbal to track the target while guiding the target to avoid highly degraded areas.
