Technical Field

Mapping is often an indispensable link in mechanical design work. The common mechanical mapping method is that the mapping personnel measures the size parameters of the measured object or equipment by using a ruler, records the measured parameters, and then models the measured parameters on a computer by combining the measured data.
The application of automatic mechanical equipment in the kelp seedling clamping operation is an important way for improving the seedling clamping operation efficiency and saving labor. In the early-stage design working process of the automatic kelp seedling clamping device, a large amount of mapping work is also required. For example: in order to enable the automatic kelp seedling clamping equipment to better conform to the shape characteristics of kelp seedlings, a large number of kelp seedlings with different sizes need to be measured and modeled, and are assembled with a prototype model in three-dimensional design software to observe whether the operation effect of a relevant mechanism of the automatic kelp seedling clamping equipment conforms to the expected assumption or not; the kelp automatic seedling clamping equipment sometimes needs to be installed on other related equipment (such as a fishing boat and the like) for combined operation, and at the moment, the size parameters of the related equipment need to be mapped so as to ensure that the kelp automatic seedling clamping equipment can be normally installed; the kelp seedling automatic clamping device designed and trial-produced for the first time is bound to be changed for a plurality of times in the process of testing and debugging for a plurality of times, and the change is usually directly carried out on a prototype according to the test effect without changing the previous drawing. After a plurality of times of test debugging and structural improvement, the sample machine has the best operation effect, and at the moment, the sample machine with the best operation effect needs to be subjected to surveying and mapping again to form a new drawing so as to realize batch production.
However, the above-mentioned situation will have the following disadvantages if the conventional mapping method is adopted:
(1) parameters need to be measured firstly in the surveying and mapping process, then modeling is carried out, a certain time difference exists between the two processes, and the efficiency is low;

(3) for the application scenario of the invention, the mapping field is often harsh; for example, when mapping kelp seedlings, the field is relatively humid and is covered with corrosive seawater. The surveyor often has the inconvenience of recording data while surveying and even causing damage to the computer used for modeling if the modeling work is performed immediately thereafter.
