Embodiment Construction
[0038] A method for moving positioning targets such as figure 1 shown, including:
[0039] Step 101: Acquire the latitude, longitude and altitude of the measurement device at the initial measurement position, locate the target, measure the distance between the measurement device and the target as the target initial distance, measure its azimuth as the target initial azimuth, and the pitch angle is the initial pitch angle of the target;
[0040] In this embodiment of the present invention, a positioning request may be sent to a satellite positioning system, where the satellite positioning system may be implemented by adopting one or more of the following combinations: GPS, GLONASS, GALILEO ) system, Beidou. In this technical solution, it is preferable to use Beidou for target positioning. Since Beidou is independently developed by my country, the target can be positioned safely and reliably. After the positioning request is sent and the positioning information is received, t...

The invention discloses a method for a mobile positioning target. A measuring apparatus is employed for positioning the target twice so as to obtain the initial distance and the current distance of the target respectively, and for measuring the azimuth of the target while positioning the target so as to obtain the initial azimuth and the current azimuth respectively; the measuring apparatus measures the pitching angle of the target so as to obtain the initial pitching angle and the current pitching angle of the target respectively; and then the measuring apparatus carries out calculation on the basis of the above-mentioned results and the latitude and longitude, altitude, azimuth and pitching angle of the measuring apparatus in two positioning operations so as to obtain the longitude and latitude, altitude, definite motion state, motion range and geographical environment of the target at a current measuring position. For users, a technical scheme provided by the invention is simple to operate and easy to implement.
Description
technical field [0001] The invention belongs to the technical field of photoelectric observation, and particularly relates to a method and a measuring device for moving a positioning target. Background technique [0002] Obtaining target information can provide guidance for the command center or its own defense system, thereby enhancing the ability to attack the enemy and its own defense and attack capabilities. [0003] With the rapid development of science and the rapid progress of optoelectronic technology, optoelectronic technology has been widely used in the field of positioning targets. However, many factors will affect the accuracy of target positioning and the effectiveness of obtaining relevant information about the target. The inventors found that in the prior art, when a target is detected, only relevant information of the target can be detected at a certain moment, and for a moving target, the movement state and movement law of the target cannot be accurately ob...
