Abstract

The invention provides a parking guide method and a parking guide device. The method comprises the following steps of: reading a region image by using an image sensor, detecting running speed by using a speed sensor, and detecting a retransmission distance between the current vehicle and an obstacle through a lateral distance sensor; acquiring the relative coordinate of the current position of the vehicle and a parking lot and the angle and the width of the parking lot by using a processor according to the region image, the running speed and the distance; accordingly, estimating a preset parking guide frame and the relative position between the preset parking guide frame and the parking lot; marking the parking lot and the preset parking guide frame on a display screen, so that a driver can move the vehicle according to the display screen; and moving the preset parking guide frame to be coincided with the parking lot to position the vehicle at the best starting position, namely controlling a steering wheel manually or automatically to stop the vehicle into the parking slot so as to effectively improve the convenience of parking.

Description

technical field [0001] The present invention relates to a parking guidance method and device, in particular to a parking guidance method and device that can pre-estimate the preset parking guidance frame of various parking modes to assist the driver to park quickly and accurately. Background technique [0002] With the rapid development of technology and equipment, such as automobiles, as a means of transportation and transportation, the quality of human life has been greatly improved, and it has already played an important and indispensable role. Therefore, with the rapid increase in the number of cars and the difficulty of finding an inch of land in the metropolis, the resulting traffic congestion and the relative pressure on parking spaces are doubled. It is common for drivers to wander around in the same area for a long time in search of parking spaces. Most of them are In addition to finding no parking space, some may miss the parking space and have to find a new parkin...
