Example Embodiment
[0062] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.
[0063] According to the characteristics of the exponential function, the present invention introduces an exponential function to calculate the probability value, which effectively reflects the relationship between the ratio of each point to the two-way distance and the weight that should be assigned. Realize good information fusion of CT data and optical data, and provide convenience for the later reverse reconstruction.
[0064] The application principle of the present invention will be described in detail below with reference to the accompanying drawings.
[0065] Such as figure 1 As shown, the white light data and CT d...
