Con el desarrollo de la ciencia y la tecnología y la apertura de políticas nacionales, la caza legal se ha convertido gradualmente en un nuevo tipo de entretenimiento al aire libre. Hay muchos fanáticos militares y entusiastas del aire libre que tienen una demanda creciente de cámaras térmicas y dispositivos de visión nocturna. Al mismo tiempo, muchos internautas con una fuerte sed de conocimiento se preguntan: ¿Qué son exactamente las cámaras térmicas y los dispositivos de visión nocturna?


Today, preste atención, ¡nuestra conferencia de conocimiento está abierta!


In Las cámaras térmicas cortas y los dispositivos de visión nocturna son equipos de alta tecnología que pueden proporcionarle con imágenes de alta definición en la oscuridad y pueden obtener fácilmente imágenes claras de objetivos en un entorno completamente oscuro.

At presente, han sido ampliamente utilizados en seguridad militar, tecnología industrial, conducción asistida por automóviles, inspección de prevención de epidemias, prevención de incendios forestales, caza al aire libre y medicina.


So ¿Cuál es la diferencia entre las cámaras térmicas y los dispositivos de visión nocturna? Seguir leyendo:


Thermal las imágenes son infrarrojas pasivas, que se basan en recibir energía infrarroja (temperatura / energía térmica) emitida por el propio objeto, y luego la presentan a través de la pantalla después de recibir y procesar.


The la imagen resultante tiene múltiples modos de visualización. Por ejemplo, los productos de imagen térmica de PARD Technology tienen cinco modos de imagen: seudo-color rojo caliente, blanco caliente, negro caliente, rojo hierro y cielo. Las imágenes térmicas no dependen de sí mismas para emitir rayos infrarrojos, sino que solo reciben rayos infrarrojos del mundo exterior.


Night los dispositivos de visión están activos, lo que significa que la luz debe reflejarse en los objetos y el dispositivo de visión nocturna recibe la imagen. Los dispositivos de visión nocturna del rango civil suelen ser dispositivos digitales de visión nocturna, que se pueden utilizar tanto de día como de noche. En buenas condiciones de iluminación durante el día, el efecto de imagen es más claro y algunos productos pueden presentar imágenes en color.


At de noche, en condiciones de fuentes de luz externas o luces de autollenado, la mayoría de las imágenes son en blanco y negro. En un entorno completamente oscuro, los productos de visión nocturna digital de PARD Technology pueden proporcionar imágenes de visión nocturna de alta definición dentro de un rango de infrarrojos de 350 m.

So desde la perspectiva de las necesidades de caza al aire libre, ¿cómo elegir dispositivos de imagen térmica y dispositivos de visión nocturna? Lo siguiente proporcionará una respuesta sencilla para las necesidades iniciales de amigos con:


In el entorno de caza nocturna, se utilizan gafas de visión nocturna para observar el objetivo. La distancia que se puede observar es relativamente cercana, y el efecto de imagen es más cercano a la apariencia real del objetivo observado en sí, pero hay ciertas limitaciones, es decir, el objetivo se confunde fácilmente cuando se mezcla con el medio ambiente y no es fácil de encontrar.

However, su imagen es más realista, y la apariencia y el contorno reales del objeto se pueden observar desde una cierta distancia, y su precio es relativamente barato, por lo que los amigos con de bajo presupuesto pueden elegir gafas de visión nocturna.


In comparación, la distancia de detección de las cámaras termográficas es mayor, y utiliza el principio de imagen térmica, utilizando la diferencia de temperatura para distinguir entre fuentes de calor e interferencias ambientales circundantes, por lo que es más fácil encontrar la existencia del objetivo. Sin embargo, su precio es generalmente más caro y el umbral de entrada es más alto.


Thermal Imagers And Night Vision Devices


Finally, en resumen, no hay diferencia entre los dos productos, depende de sus necesidades y presupuesto. Aquí, también deseo que cada espectador pueda encontrar un producto de visión nocturna de imagen térmica que le convenga y que le guste.
