Embodiment Construction

[0014] The method of the present invention adopts the grayscale table corresponding to the specific required characters, and according to the grayscale table, the required characters can be displayed simply and quickly during the character display process. First, make the bmp file of the required characters in the drawing tool, use VisualDsp++ software to import the file and convert it into a dat file containing 16-bit data, when the infrared system is initialized, allocate memory space to import the data of the dat file, and then when the characters are displayed Call different address segments of this space according to requirements to display different characters. Using this method to realize the display of infrared image characters see process figure 1 ,Specific steps are as follows:

[0015] (1) First enter all the characters to be displayed in the drawing tool, for example, take the character "infrared image" and adjust the size of the characters to 14x14, the position ...

Abstract

The invention relates to a character display method on the basis of an infrared image and belongs to the technical field of infrared image processing. The character display method on the basis of the infrared image comprises the following steps of: firstly, inputting all characters which need to be displayed in a drawing tool and generating a bmp (Bitmap) file of the characters by regulating the positions and the sizes of the characters; introducing the bmp file by a Visual Dsp++ tool, converting each pixel into hex data and carrying out integration to generate corresponding dat files; when an infrared system is initialized, distributing a corresponding memory space and introducing the pixel data in the dat files in sequence; and in the operating process of the infrared system, displaying different characters by calling different address fields in the memory space. Due to the adoption of the method disclosed by the invention, the character display characteristics of infrared image processing are sufficiently utilized, the optimization of the character display method in the infrared image processing is well implemented, the occupation of a character base in the memory space is reduced, and the real-time processing efficiency of character display is improved.

Description

technical field [0001] The invention relates to a character display method based on an infrared image, and belongs to the technical field of infrared image processing. Background technique [0002] Traditional character display algorithms usually need to create or call a large and complex character library, which takes up a lot of memory space during the operation process. Although it has certain versatility, it will have limited system space resources and high real-time requirements. environment is not suitable. [0003] The method of the invention aims at the characteristics of character display in the infrared system, only uses less memory space to establish the required character data files, and can be called flexibly, is simple and easy to implement, and ensures the function and performance requirements of the system. Contents of the invention [0004] The purpose of the present invention is to provide a character display method based on infrared images to solve the ...
