Small-pipe-diameter loess geological information in-situ detection environment self-adaptive visual system and method

The invention discloses a small-pipe-diameter loess geological information in-situ detection environment adaptive visual system and method. The system comprises an image acquisition module, a focusing module, an image processing module and a control module. The image acquisition module comprises a light source, a camera and a light source controller. The axis of the light source is coaxial with the imaging optical axis of the camera. The focusing module comprises a linear moving mechanism and a rotating mechanism; the image processing module comprises a photometric module, a dimming module, an image definition evaluation module and a focusing search module; the control module is used for receiving instruction information of the upper computer, sending feedback information to the lower computer and controlling the focusing module to adjust the object distance of the camera or the light source controller according to the instruction information. According to the self-adaptive vision system, an automatic focusin
