问题与措施:红外触发相机使用技术探索

Research on Infrared Camera Field Monitoring Technology

红外触发相机广泛用于自然保护区野外监测,但有效拍摄率和照片可辨识度有待提高。以甘肃白水江国家级自然保护区红外触发相机安装使用情况和拍摄得到的有效照片为对象,对比分析、归纳、整理,总结提出15项相机使用中存在的问题及其改进措施,包括机型选择、相机参数设置、障碍物清除、逆向曝光、相机与地面位置关系、相机高度、相机固定、有效距离、相机间距、相机误启动、相机保养、相机伪装、诱饵使用、位点信息和相机内存卡,需要在实际工作中予以高度重视。

Infrared trigger camera is widely used for field monitoring in nature reserves,but the effective shooting rate and the recognizability of photos need to be improved.Taking the installation and use of infrared trigger camera and the effective photos taken in Gansu Baishuijiang National Nature Reserve,as the object,through comparative analysis,induction,collation,15 problems exist in the use of cameras and their improvement measures are summarized,which includes model selection,camera parameter setting,obstacle removal,reverse exposure,relationship between camera and ground position,camera height,camera fixation,effective distance,camera spacing,camera misstart,camera maintenance,camera camouflage,use of bait,location information and camera memory card.In a word,these need to be paid high attention in practical work.
