Description
Technical field [0001] The present application relates to the field of detectors, in particular, to an incident angle calculation method, apparatus, computer device, and storage medium applied to a cylindrical matrix ray detector. Background technique [0002] The ray detector is mainly used to collect information such as energy, distribution, and state of high-energy rays, and is an important part of the radiation measurement device. The cylindrical matrix obtains information of three-dimensional spatial rays by distributing probes on the cylindrical surface. The incident angle is the basic information of the rays, obtains an accurate incident angle in real time, which is critical to subsequent calculation and processing. [0003] An incident angle calculation method is, that is, by assumed a projection plane, the upper and lower projection maps will be consistent when the probe readings on the plane and the lower probe readings are vertical and the projection planes are vertica...
