Classification: CPC G  Y | IPC G

Claim 4:
5. The target detection method based on fusion of vision, lidar, and millimeter wave radar according to claim 1, wherein:
the step 4 comprises:
arranging the second anchor point at a certain interval in a blind area in which radar points of the millimeter wave radar are not generated; and
generating the second region of interest by traversing the second anchor point with the second anchor point as the center of the second region of interest,

the short-wave detection range of millimeter wave radar from 0 to 30 meters is 90 degrees,
the short-beam detection range of millimeter wave radar from 30 to 70 meters is 18 degrees,
a long-wave detection angle at 70 meters is 18 degrees,
a range of detecting obstacles is [−30, 30, 0, 70], and
a method for determining the blind area comprises:
(1) projecting the first region of interest obtained in step 3 onto bird's-eye view plane;
(2) obtaining a background area according to a projected two-dimensional candidate frame; and
(3) generating candidate frames by traversing the background area.
