This invention belongs to the field of materials preparation and discloses a method for preparing plate-like zinc phosphate, comprising the following steps: (1) adding an inducing agent to a phosphoric acid solution; (2) adding the mixed solution from step (1) to a zinc oxide slurry, stirring the mixture at 60-90°C, and filtering and drying the reaction product after the reaction to obtain plate-like zinc phosphate. This invention directly controls the growth morphology of plate-like crystals through an aqueous synthesis reaction, eliminating the need for ultrafine grinding, reducing process flow and equipment investment, lowering energy consumption per unit product, and meeting the requirements of green manufacturing.

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. Subsequently, the matching confidence is calculated and the tracking status is determined by combining the motion trajectory consistency: re-acquisition is initiated in case of failure, and the reference template is updated only when preset update conditions are met in case of reliability. This application effectively suppresses background interference and significantly improves the accuracy and robustness of long-term tracking in complex dynamic scenes through a collaborative mechanism of environmental perception, avoidance control, and condition updating.
