An autonomous driving control system for a vehicle which is able to switch between manual driving and autonomous driving is provided with a driver condition sensor, acting part, and electronic control unit. The electronic control unit is provided with an autonomous driving control part, reliance calculating part for calculating an autonomous driving output reliance, vigilance calculating part for calculating a driver vigilance, and an action control part for controlling a strength of an action against a driver. In a region in which an operating point determined by the autonomous driving output reliance and driver vigilance can fall, a plurality of sub regions are defined by boundary lines extending so that the driver vigilance becomes higher as the autonomous driving output reliance becomes lower. The action control part controls the strength of the action against the driver to differ in accordance with the sub region in which the operating point falls.

The invention discloses a submodule-assembled three-dimensional positioning mounting method. The mounting method comprises the following steps: (1) selecting and burying datum points; (2) establishing a plane coordinate system; (3) positioning module boundary lines and central angle control lines; (4) establishing a height datum system; (5) adjusting the elevations of all modules at the bottom to be qualified; (6) controlling the position line of an inclined plate and the elevation of a WP point; (7) setting out the position line and the angle line of a peripheral circular plate, and measuring the perpendicularity; (8) controlling the position line and the elevation of an inside circular plate and measuring the perpendicularity; (9) measuring the control line and the elevation of a top cover; (10) after assembly is finished, repeatedly measuring. In the assembly process, each submodule needs to be measured and the three-dimensional coordinate of each submodule is measured; then, according to a series of technical data of welding contraction, the final position of each submodule is determined, and the assembling precision requirement is achieved; finally, the parameters such as the size and position of the module need to be converted into the position in a nuclear island coordinate system, so that the accurate position of the module in a nuclear island is determined.

The invention discloses a method for detecting a ship water gauge line. The method comprises the steps: acquiring an original image containing ship water gauge mark information through a mobile terminal; respectively inputting the original image into a horizontal line identification model and a water gauge mark identification model which are constructed in advance based on a depth separable convolution module to obtain a first image marked with a ship body water body boundary line and a second image marked with water gauge characters and contents thereof; and detecting the actual height of theship waterline according to the information marked in the first image and the second image. According to the invention, a lightweight deep learning network is used, and the detection precision and the detection speed are ensured at the same time, so that the collected image is processed at the mobile terminal.
