An adjusting method and an adjusting system of an intelligent vehicle imaging device are provided, wherein a real feature point for comparison is disposed in a monitoring area around a vehicle. A camera captures images around the vehicle. The images are transmitted to the controller and displayed on a touch display panel. The controller performs image processing on the images and the real feature point, and compares the real feature point with position data of predetermined feature points, and generates a bird's-eye view image. If the images are captured, the bird's-eye view image is rotated and scaled after conversion according to a predetermined position and a predetermined proportion and then is located on a stitched image and outputted. A blind spot area size or a lane departure parameter is selected through the touch display panel, and the stitched image is adjusted through the touch display panel.
