Abstract:
The present disclosure provides a method, a device, a terminal, a system and a vehicle for visualization of vehicle's blind spot. The method includes: acquiring real-time image data in front of the vehicle; creating a Three-Dimension (3D) map with the acquired image data; determining a current location of the vehicle in the 3D map; acquiring the relative location information between the driver and the sight-blocking object that blocks the vision of the driver; determining the blind spot in the vision of the driver in connection with structure information of the sight-blocking object and the relative location information between the driver and the sight-blocking object that blocks the vision of the driver; and determining environmental information of the blind spot in the vision in accordance with the 3D map, the current location of the vehicle in the 3D map and the blind spot in the vision of the driver.

Claim (Index 14):
The method according to  claim 13 , wherein the step of creating the 3D map or the compartment 3D model by SLAM comprises:\n acquiring real-time image data in front of the vehicle or real-time image data of the inside of the compartment of the vehicle; extracting feature points of the real-time image data in front of the vehicle or the real-time image data of the inside of the compartment of the vehicle; matching the feature points of the real-time image data in front of the vehicle or the real-time image data of the inside of the compartment of the vehicle in different frames; estimating a motion parameter of the 3D map based on the feature points successfully matched of the real-time image data in front of the vehicle or the real-time image data of the inside of the compartment of the vehicle in different frames and a normalization algorithm of the feature points; converting the feature points of the real-time image data in front of the vehicle or the real-time image data of the inside of the compartment of the vehicle in all frames to a same coordinate system in accordance with the motion parameter; and creating the 3D map or the compartment 3D model.
