Problems solved by technology

Since every turn, only the area currently covered by the sensor can be detected, and other uncovered areas cannot be detected, and full-time 360° detection cannot be realized. Even if the scanning frequency of the scanning motor is increased, this problem cannot be eliminated.
The scanning motor and transmission part not only increases the complexity of the system, but also the mechanical life of this part restricts the service life of the whole system

Abstract

The invention discloses a 360° detection sensor based on an area array CCD / CMOS and a detection method, including an area array CCD / CMOS sensor, a conical mirror, a light-shielding tube, a light source, a collimating lens, an optical filter, a cylindrical window, Circular aperture diaphragm, after the light source passes through the collimating lens, after being emitted through the conical mirror, it is emitted through the cylindrical window, and after meeting the reflector, it is reflected by the reflector through the conical mirror, and then emitted through the conical mirror, and the light passing through the circular aperture Diaphragm, filter reflected to the area array CCD / CMOS sensor. Correspondingly, a detection method based on the above-mentioned area array CCD / CMOS 360° detection sensor is also provided. The present invention realizes 360° no dead angle detection, realizes full coverage detection of one machine, or area detection, and can be used for perimeter collision avoidance , area security, contour detection, contour detection, angle tilt and other applications. In addition, the method of image difference is adopted, which has strong anti-interference ability to the environment.

Description

technical field [0001] The invention relates to the technical field of sensors, in particular to a 360° detection sensor and a detection method based on an area array CCD / CMOS. Background technique [0002] The core components of the existing 360° sensors are ordinary photoelectric sensors and mechanical parts that can drive ordinary sensors to rotate at high speed. Ordinary photoelectric sensors can only detect objects within a small angle range in the horizontal direction. To achieve 360° detection, a 360° scanning motor is required to drive the photoelectric sensor to rotate and scan through the transmission part. Since every turn, only the area currently covered by the sensor can be detected, and other uncovered areas cannot be detected, and full-time 360° detection cannot be realized. Even if the scanning frequency of the scanning motor is increased, this problem cannot be eliminated. . The scanning motor and transmission part not only increases the complexity of the ...
