Abstract: A ranging system includes a pinhole camera, a fisheye camera and a processor. The pinhole camera captures a pinhole image. The fisheye camera captures a fisheye image. The processor performs a undistorting process on the fisheye image to obtain a corresponding undistorted fisheye image, perform a size-converting process on the pinhole image to obtain a corresponding size-converted pinhole image, obtain a transformation relation between a pinhole image plane of the pinhole camera and a fisheye image plane of the fisheye camera, obtain a corresponding point of the corresponding undistorted fisheye image corresponding to a target point of the corresponding size-converted pinhole image based on the transformation relation, and obtain a distance between the ranging system and the physical point based on the transformation relation, the target point and the corresponding point.

Abstract: A driving environment monitoring system includes a line-of-sight analysis module, an environment analysis module and a processor. The line-of-sight analysis module captures an eye image of a driver; and analyzes the eye image to obtain a plurality of line-of-sight probabilities that a line-of-sight of the eye image is located in a plurality of partitions. The environment analysis module is configured to capture an environment image around the mobile vehicle; and analyze the environment image to obtain a plurality of object probabilities that at least one object of the environment image is located in the partitions. The processor is configured to obtain an integration probability of the line-of-sight probability and the object probability in each partition; obtain a forward direction of the mobile vehicle; and send a reminder signal based on the integration probability of the partition where the forward direction is located being greater than a preset probability.

Abstract: A processing method for vehicle surround view, a vehicle surround view system and an in-vehicle processing device are provided. The processing method for vehicle surround view includes the following steps: obtaining a first exterior image and a second exterior image; recognizing a first interest object in the first exterior image and a second interest object in the second exterior image; fitting the first interest object to a first geometric contour and fitting the second interest object to a second geometric contour; applying the first geometric contour and the second geometric contour on a 3D model, to obtain a ground point, a first contour position and a second contour position; obtaining a merged contour position according to the ground point; and projecting the first interest object or the second interest object at the merged contour position on a vehicle surround image.
