Intelligent instrument has been widely used in various fields of life and production. When it was used with monitoring technology, the problem of measuring dangerous area can be solved efficiently. In this paper, character tilt and location were brought into focus. To solve tilt problem, rotation correction method was proposed based on the theory of perspective projection transformation. To solve location problem, sliding window method was proposed by using gray comparison. Experimental results show that these two methods can solve character tilt and location problem in character recognition of intelligent instrument.
