Cruise-assist image generation device, cruise-assist image generation method, in-vehicle camera and equipment-control assist image generation device

摘要

A cruise-assist image generation device includes a steering-angle information acquisition unit, an additional line generation unit generating a cruise assist additional line corresponding to acquired steering angle information and formed by combination of a given number of segments, and an additional line superimposing unit superimposing the generated cruise assist additional line on a taken image of the vehicle periphery to obtain a composite image. The additional line generation unit generates respective curved lines forming at least some of the segments by quadratic curve approximation using coordinate data corresponding to the acquired steering angle information and including coordinates of points representing each segment, and generating respective straight lines forming any remaining segments by collinear approximation using coordinate data corresponding to the acquired steering angle information.

1. A cruise-assist image generation device comprising:
a steering angle information acquisition circuitry configured to acquire, repeatedly at a time interval, steering angle information of a steering wheel; a memory configured to store a plurality of data sets in a lookup table, each data set of the plurality of data sets includes coordinate data corresponding to a different steering angle of a plurality of steering angles; an additional line generation circuitry configured to:
select a data set from the plurality of data sets in accordance with the steering angle information,generate a cruise assist additional line formed by a combination of a number of vertical segments and a number of horizontal segments based on the data set selected from the plurality of data sets, andupdate the cruise assist additional line based on a change of the steering angle information; and an additional line superimposing circuitry configured to superimpose the cruise assist additional line on an image of a vehicle periphery, wherein
the each data set of the plurality of data sets includes a common coordinate between at least one of the vertical segments and at least one of the horizontal segments that form the cruise assist additional line.
