Abstract
A three-dimensional object detection method includes: determining first plane coordinates of multiple landing points of a first object based on a projection frame of the 3D first object in a to-be-detected image, the to-be-detected image being captured by an image acquisition device; obtaining first world coordinate information based on a world coordinate system established based on position information and size information of the first object, the first world coordinate information including first world coordinates of the multiple landing points of the first object and first word coordinates of multiple vertices of the first object; and using coordinate conversion processing to obtain external parameter information that converts the world coordinates of the first object into camera coordinate based on the first plane coordinates, the first world coordinates of the multiple landing points of the first object, and the internal parameter information of the image acquisition device.
