The present invention discloses an image searching and capturing system and a control method thereof. The system comprises a first capture device, a second capture device, a control module and a processing module. The first capture device captures a plurality of multi-spectral panoramic images with panorama. The control module controls the second capture device to search and target an azimuth of target object according to the plurality of multi-spectral panoramic images; the control module controls that the second capture device rotates a rotation module to capture a high-resolution image of a target object. The control module controls a rotation angle and a rotation direction of the rotation module according to attitude information, position information, and azimuth of the target object. The invention is applied to environmental monitoring and disaster monitoring, and has automatic search for targets, calibration targets and achieve high-resolution images and other effects.
