Embodiment approach

[0042] The specific implementation method is: the infrared telescope is aimed at the scene including the target to be identified, and when the target detection function is enabled by the software, the wk model file is called from the memory of the embedded chip to generate a detection model, and the software loads the obtained infrared image into the detection model Calculate in , obtain the target category in the infrared image and the rectangular frame covering the whole target.

[0043] Target distance measurement: Calculate the distance between the target and the observer based on the preset height of the target to be measured, the pixel height of the target person or object in the picture, the lens focal length of the known infrared telescope and the pixel size of the detector.

[0044] The specific implementation method is: the pixel height of the rectangular frame covering the whole target obtained by target detection is regarded as the pixel height of the target person ...

Abstract

The invention relates to a distance measuring method and system based on external equipment and an infrared telescope. Infrared glass lenses with different curvatures and different refractive indexes are arranged on the same axis in the infrared telescope to form an infrared imaging lens; the infrared light sensing unit is arranged to be an uncooled infrared focal plane array to form an infrared detector in the infrared telescope. The distance measuring method of the infrared telescope comprises the following steps: determining the category of a target to be measured, calibrating a data set, training a detection model, importing the model, detecting the target, measuring the distance of the target, identifying an image, and observing and displaying. According to the method, the detection model used for target detection is obtained through acquisition of the infrared data set, data set calibration and model training, the detection model is used for performing category identification, target distance measurement, image identification and identification superposition on the infrared target, real-time distance measurement and labeling of the infrared image target are completed, and the problem that in the prior art, the detection efficiency is high is solved. The distance measurement operation is complex, and the distance measurement error is large.

Description

technical field [0001] The invention relates to a ranging system, in particular to a ranging method and system based on external equipment and an infrared telescope. Background technique [0002] An infrared camera is an electronic device that receives the infrared light emitted or reflected by the scene itself to achieve the purpose of imaging the scene. The infrared telescope is an observation product that integrates a miniaturized infrared camera, an electronic display screen and a battery module, and can transmit instant infrared images to users. Because infrared images can distinguish targets at different temperatures and are not affected by ambient light, they are often used in wild hunting, police reconnaissance and other fields, especially at night. When users need to obtain the distance value of the observed target, they can use physical distance measurement and image distance measurement. Physical ranging is to integrate an optical ranging module on the infrared ...
