The present disclosure provides a method and an apparatus for binocular ranging, capable of achieving an improved accuracy of binocular ranging. The method includes: extracting features from a left image and a right image to obtain a left feature image and a right feature image; selecting a standard feature image and obtaining a cost volume of the standard feature image by applying a correlation calculation to the left feature image and the right feature image using a block matching algorithm; obtaining a confidence volume by normalizing computational costs of all disparity values in a disparity dimension for each pixel point in the cost volume; obtaining a confidence map by selecting a maximum value from confidence levels of all the disparity values in the disparity dimension for each pixel point in the confidence volume; obtaining a mask map by mapping each pixel point having a confidence level higher than a predetermined threshold in the confidence map to 1 and mapping each pixel point having a confidence level lower than or equal to the threshold in the confidence map to 0; obtaining a disparity map by calculating an argmax value for the confidence levels of all disparity values in the disparity dimension for each pixel point in the confidence volume; obtaining a target disparity map by multiplying the mask map with the disparity map; and estimating a distance based on the target disparity map.

Systems, methods, and devices for providing an adjusted yardage recommendation (AYR) to a golfer prior to a golf shot. AYRs are determined based on predicted golf ball trajectories that are modeled from a golfer's golf ball launch data, using non-classical mathematical approximation methods. Each of the modeled trajectories are unique, and result in personalized AYR values that are personalized to each individual golfer, even where two golfers hit a ball with the same club the same distance while having two different ball flights. Devices that can perform the methods of the present invention include rangefinder devices and/or portable computing devices, such as a smartphone. Systems can include a rangefinder device and a portable computing device, in which the rangefinder device determines the line-of-sight distance and angle of elevation to a target and communicates the same to the portable computing device, which calculates the AYR.
