[0003] However, in the prior art, in the process of measuring the movement distance of the vehicle or other smart devices, the distance information of the vehicle or moving object is calculated according to the real-time position measured by GPS, that is, the distance between the position coordinate points of two adjacent positionings is accumulated. However, this method of only relying on GPS to calculate the movement distance of vehicles or moving objects has disadvantages, because GPS can only measure the horizontal distance traveled by moving objects (including vehicles or moving objects), However, when the moving target is in an uphill or downhill state, the actual moving distance of the moving target is greater than the distance measured by the GPS. There are errors in the calculation of energy consumption information, which reduces the accuracy of distance measurement of moving targets and affects the measurement effect

The embodiment of the invention discloses a distance measurement method and a distance measurement device. The method comprises the following steps: acquiring GPS data information of a moving target; acquiring gradient information corresponding to the GPS data information from a three-dimensional map according to the acquired GPS data information; calculating a moving distance of the moving target according to the GPS data information and the gradient information. According to the method and the device, the actual moving distance of the moving target can be precisely calculated, and the distance measurement accuracy can be improved.
Description
technical field [0001] The invention relates to the field of measurement technology, in particular to a distance measurement method and device. Background technique [0002] With the rapid progress and popularization of GPS technology, its role in the field of measurement has become more and more important. For example, the vehicle-mounted GPS is generally installed on the vehicle now, and the vehicle-mounted GPS can locate the accurate position of the vehicle so as to guide the user, and can measure the distance information, speed information or fuel consumption information of the vehicle on the road; GPS smart bracelets or other smart measuring devices can also locate the exact position of moving objects, and can measure the movement distance information of moving objects. [0003] However, in the prior art, in the process of measuring the movement distance of the vehicle or other smart devices, the distance information of the vehicle or moving object is calculated accord...
