Problems solved by technology

[0003] At present, there are the following problems to be solved for underwater welding: 1. The accuracy and efficiency of manual welding are not high; 2. The mechanical welding method has a specific structure that needs to adapt to the underwater environment, especially the image that needs to overcome various underwater disturbances Processing equipment; 3. Lack of automatic welding equipment
Therefore, in the prior art, mechanical welding cannot be used to weld underwater equipment, resulting in the current welding method being slow and inaccurate

Embodiment Construction

[0015] The implementation of the underwater robot based on multiple filter processing of the present invention will be described in detail below with reference to the accompanying drawings.

[0016] Underwater welding must first accurately identify the position of the weld. In the prior art, image recognition is generally used. However, the shutter control of current underwater laser imaging is difficult, resulting in poor underwater laser image effects and the lack of suitable underwater positioning. equipment and image filtering equipment, so that the accuracy of underwater welding is not high.

[0017] In order to overcome the above-mentioned shortcomings, the present invention builds an underwater robot based on multiple filter processing, uses multiple filter methods to preprocess images, optimizes underwater laser imaging technology and underwater equipment positioning technology, and at the same time, transforms underwater robots and Welding equipment makes automatic un...
