This invention relates to a method for continuous injection path planning for multiple piglets, which solves the technical problem of how to achieve rapid and continuous injection of vaccines into piglets using a robotic system, thereby improving operational efficiency, reducing the labor intensity of operators, and lowering labor costs. The method uses machine vision to obtain N injection points for multiple clamped and restrained piglets, sorts these N injection points to generate an injection sequence, and places the injection point with the shortest movement time (greater than T) of the veterinary needleless injector at the beginning of the injection sequence, while placing those with longer movement times at the end. This invention has wide applications in the field of swine disease prevention and control technology.

The present invention relates to the field of medical puncture technology, and specifically to a puncture path planning method and system based on an optimization strategy and a needle tip retraction strategy, comprising the following steps: kinematic analysis of the puncture needle to construct a kinematic model of the puncture needle puncture path; based on the kinematic model of the puncture needle puncture path, a multi-objective function for puncture needle puncture path planning is constructed; based on the multi-objective function, the kinematic model of the puncture needle puncture path for puncturing multiple target points is optimized and solved by using an optimization algorithm combined with a needle tip retraction needle insertion strategy, to obtain the optimal puncture needle puncture path for puncturing each target point one by one. The present invention performs puncture path planning by means of an optimization strategy, establishes constraints between multiple objectives, and controls the constraint direction by setting weights, so that the optimization direction is controllable, and thus the effect of path planning is controllable, thereby achieving the optimization of path planning.

A copywriting rewriting system for digital human live broadcast belongs to the technical field of computer programs, and expands a plurality of different expression modes which do not change original meaning according to the content of an original verbal skill copywriting based on a segment of existing live broadcast verbal skill copywriting, a target verbal skill length (or playing duration) and a non-repetition rate of the target verbal skill. And character contents are ensured not to be repeated. According to the invention, one-time off-line operation before broadcasting can be realized. In order to further ensure the safety of the content, the limited content generated by the method can be manually examined before broadcasting, so that the safety and the accuracy of the content are ensured, and the risk caused by forbidden words, inaccurate content or repeated texts and the like in the live broadcasting process is reduced to the minimum.
