3results about How to "Narrow detection range" patented technology

This application relates to the field of automatic control technology and provides a method, apparatus, and storage medium for controlling the recharge of a self-moving device. The method includes: acquiring an environmental image of the self-moving device during the recharge process; performing target detection on the environmental image to obtain a first detection frame including the charging dock; extracting a second detection frame corresponding to the charging dock features from the first detection frame; wherein the charging dock features are identifying features on the charging dock, and the image area of ​​the second detection frame is smaller than that of the first detection frame; determining the position information of the second detection frame; and controlling the self-moving device to move towards the charging dock based on the position information of the second detection frame. This application solves the problem of inaccurate control of the self-moving device returning to the charging dock. By narrowing the target detection range, the recharge control of the self-moving device can be made more precise.

The application relates to a fire hose inspection and detection device and relates to the field of fire hose detection, which comprises a test table, water outlet boxes and water storage frames arranged in a diagonal line on the left and right sides of the test table, two locking mechanisms corresponding to the water outlet boxes and the water storage frames respectively arranged at the upper end of the test table, and an environment simulation unit arranged between the two locking mechanisms. The fire hose is arranged in an S-shaped mode for subsequent detection, the overall detection range of the fire hose is shortened, the fire hose can be fully detected in a long enough detection length, and the authenticity of the fire hose detection result is greatly improved; the use condition of the subsequent fire hose after back and forth friction with different ground is simulated by replacing the environment simulation plate and the friction sleeve, the limitation of the fire hose detection in a single environment is changed, the quality of the fire hose is more comprehensively detected, and a more accurate wear resistance detection result is obtained.
