The invention discloses a precise and quick positioning method for vision. On a substrate, small holes with the same size are processed to manufacture a target, a back illumination light source is adopted to carry out illumination on the target; the target is attached to a tested object; when the tested object generates displacement, the target is driven to move, and therefore, all small holes move together; a digital camera is adopted to carry out visual imaging on the target, and the collection of a target light spot and light spot displacement information can be finished through computer image processing; a new sub-region grid positioning method is used for realizing light spot positioning; and therefore, the precise displacement of the tested object is determined. The method innovatively adopts a machine vision technology to process the relative positions of the light spots on different positions, and utilizes a grid region division way to extract the precise displacement information of the system so as to realize non-contact precise positioning, errors can be effectively reduced, and light spot micrometric displacement accuracy is improved.

The invention discloses an infrared characteristic simulation system for a target. The system comprises multiple simulation target plates used for simulating infrared characteristics, temperature control boxes which are in one-to-one correspondence with the simulation target plates, a temperature monitoring center and a power supply system; a temperature sensor collects temperatures of the simulation target plates and transmits the temperatures to the temperature control boxes which upload the temperature values to the temperature monitoring center, the temperature monitoring center gives temperature control instructions to the corresponding temperature control boxes according to the surface temperatures of all the simulation target plates and the infrared characteristic test requirements,and the temperature control boxes control on and off of power supply lines between the power supply system and the simulation target plates. Accordingly, by splicing the simulation target plates intoa set shape, the temperatures of the simulation target plates are collected so as to adjust the average output power of a heating layer in the simulation target plates, and dynamic equilibrium of a simulation target plate temperature field is achieved.
