Local stereoscopic vision infrared camera system and method for wild animal monitoring

Abstract

The invention provides a local stereoscopic vision infrared camera system and method for wild animal monitoring. The local stereoscopic vision infrared camera system comprises two image acquisition modules, an induction triggering module, a synchronous control module and an image processing module; the two image acquisition modules are arranged up and down, and the view fields are partially overlapped; the two image acquisition modules are used for synchronously acquiring binocular images; the induction trigger module is used for infrared induction of wild animal motion information and acquisition of infrared signals; the synchronous control module receives a trigger signal sent by the induction trigger module and controls the two image acquisition modules to be opened and closed; and theimage processing module receives the binocular images acquired by the two image acquisition modules, corrects the binocular images according to calibrated internal and external parameters and lens distortion information, performs binocular matching on the view field overlapping part, and measures the wild animal size in a three-dimensional way. According to the invention, the field of view is expanded, the effective detection efficiency of the animal target is improved, and the high-precision size information of the target can be obtained.

Description

technical field [0001] The present disclosure relates to the field of infrared cameras, in particular to a local stereo vision infrared camera system and method for wild animal monitoring. Background technique [0002] Infrared cameras are often used in the monitoring of wild animals in recent years. Compared with other monitoring methods such as GPS tags and radios, they have the advantages of non-damage, good data robustness, and more additional information. Its basic working principle is to sense the movement information of animals through infrared sensors, and then trigger the camera to take pictures to obtain animal images. [0003] For the acquisition of size information of animal targets, there are currently three main technologies: TOF camera, structured light camera and binocular camera. The TOF camera calculates the distance of the target by the time difference between the transmitted pulse and the returned pulse, and can quickly identify and measure the target. T...

Problems solved by technology

The TOF camera calculates the distance of the target by the time difference between the transmitted pulse and the returned pulse, and can quickly identify and measure the target. The problem is that the cost is high and the resolution is relatively low, and the TOF camera technology is active imaging, which is easy to cause interference to animals. ;The structured light camera obtains the modulation pattern by projecting structured light on the target surface, and then calculates the target siz...
