Abstract

The invention relates to a joint calibration method and device based on a radar and a camera, electronic equipment and a computer readable storage medium. The method comprises the following steps: acquiring radar coordinates of a to-be-monitored object under a radar coordinate system and camera image coordinates under a camera image coordinate system; constructing a conversion relation between the radar coordinate system and a camera image coordinate system according to the radar coordinates and the camera image coordinates; and performing joint calibration on the radar and the camera according to the conversion relation to obtain the calibrated pitch angles of the radar and the camera. According to the joint calibration method based on the radar and the camera provided by the invention, rapid and accurate joint calibration between monitoring equipment is realized.

Description

technical field [0001] The present invention relates to the technical field of multi-sensor joint calibration, in particular to a joint calibration method, device, electronic equipment and computer-readable storage medium based on radar and camera. Background technique [0002] With the development of technology monitoring technology in modern society, there are more and more environments and places that need to be monitored, such as traffic monitoring, assisted driving, unmanned driving, etc. Traditional monitoring methods use single sensors, such as camera sensors or millimeter-wave radars sensor. [0003] The camera sensor can directly obtain visual information, can monitor intuitively and is cheap to manufacture, but it is easily affected by environmental factors such as weather and light, and its positioning is not accurate enough; although the millimeter-wave radar sensor is not easily affected by environmental factors and can accurately locate, it is not With visual ...
