Infrared light source type selection method in infrared camera based on optical simulation software

Abstract

The invention discloses an infrared light source type selection method in an infrared camera based on optical simulation software, and the method comprises the steps: building a plurality of differentlight source models through an existing camera structure, adding the light source models into the camera structure, and enabling any two light source models to have the same number or arrangement mode of lamp beads; inputting a power parameter and a wavelength range of an infrared light source; outputting performance parameter distribution for different light source models, and picking out the light source model with the minimum difference according to the required performance parameter distribution; enabling the performance parameter distribution to be close to the required performance parameter distribution as much as possible by changing the radiation angle and the radiation power; outputting the parameters of the radiation angle and the radiation power obtained in the step S4; and processing the data in the S5 through the correction parameters, and applying the actually processed data. Through the arrangement, the emission angle and the radiation power parameter of the infrared light source can be quickly and accurately obtained, and the method has the advantage of low cost in the model selection process.

Description

technical field [0001] The invention relates to the field of optical simulation, in particular to a method for selecting a type of infrared light source in an infrared camera based on optical simulation software. Background technique [0002] The traditional infrared light source selection method is to select an infrared light source with a suitable luminous angle and power based on experience, and then get samples for actual testing and evaluation, and obtain an infrared light source that meets the needs based on the actual measurement and comparison of multiple samples. [0003] The traditional infrared light source selection method has the following disadvantages: [0004] ①The traditional selection method can only roughly select the angle and power based on experience, and cannot intuitively obtain the irradiance distribution of the selected infrared light. It can only be obtained through actual testing, and the efficiency is low. [0005] ② If the infrared light board ...

Problems solved by technology

[0004] ①The traditional selection method can only roughly select the angle and power based on experience, and cannot intuitively obtain the irradiance distribution of the selected infrared light. It can only be obtained through actual testing, and the efficiency is low

[0006] If the structure changes, such as changes in the number and arrangement of infrared lamps, the required angle and radiation power cannot be judged by experience

[0007] ③If there is a structure outside the infrared lamp to reflect or absorb infrared light, it will cause the intensity of infrared light to weaken, and it cannot be accurately judged by experience
