[0031] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0032] The present invention provides a semi-global stereo matching method using cost fusion and hierarchical matching strategy. The flow chart is as follows: figure 1 As shown, the method includes the following steps: Step 1) Determine the number of pyramid layers N according to the input image and initialize the top-level parallax search range; Step 2) On the basis of step 1), the algorithm starts to perform hierarchical iterative matching, and each layer matches There are multi-threading and SIMD instruction set to accelerate the calculation.
[0033] Step 1) Determine the number of pyramid layers N according to the input image and initialize the top-level disparity search range.
[0034] Step 2) On the basis of step 1), the algorithm starts to perform hierarchical iterative matching, and each layer of matching has multi-threading and S...
