Abstract
Embodiments of the present disclosure relate to positioning target device. According to embodiments of the present disclosure, the location of the target device is measured by two anchor devices. The distances between the target device at a location and the anchor devices are measured and the distances between the target device at a further location and the anchor devices are also measured. The location of the target device is estimated based on the distances. In this way, fewer anchor devices are used to perform the positioning.
Claims20
A target device, comprising:
- at least one processor;
- and
- at least one memory including computer program codes;
- the at least one memory and the computer program codes configured to, with the at least one processor, cause the target device to:
- obtain a first distance between the target device at a first location and a first anchor device at a second location and a second distance between the target device at the first location and a second anchor device at a third location;
- obtain a third distance between the target device at a fourth location and the first anchor device at the second location and a fourth distance between the target device at the fourth location and the second anchor device at the third location;
- determine an angle between first line connecting the first and fourth locations and second line connecting the second and third locations, wherein the angle is determined based on angles between the first line and each of planes XY, YZ, and XZ, respectively;
- and
- obtain a first coordinate of the first location and a second coordinate of the fourth location relative to the first and second anchor devices based at least in part on the first, second, third and fourth distances and the angle.
A method comprising:
- obtaining, at a target device, a first distance between the target device at a first location and a first anchor device at a second location and a second distance between the target device at the first location and a second anchor device at a third location;
- obtaining a third distance between the target device at a fourth location and the first anchor device at the second location and a fourth distance between the target device at the fourth location and the second anchor device at the third location;
- determining an angle between first line connecting the first and fourth locations and second line connecting the second and third locations, wherein the angle is determined based on angles between the first line and each of planes XY, YZ, and XZ, respectively;
- and
- obtaining a first coordinate of the first location and a second coordinate of the fourth location relative to the first and second anchor devices based at least in part on the first, second, third and fourth distances and the angle.
A computer readable medium storing instructions thereon, the instructions, when executed by at least one processing unit of a machine, causing the machine to perform:
- obtaining, at a target device, a first distance between the target device at a first location and a first anchor device at a second location and a second distance between the target device at the first location and a second anchor device at a third location;
- obtaining a third distance between the target device at a fourth location and the first anchor device at the second location and a fourth distance between the target device at the fourth location and the second anchor device at the third location;
- determining an angle between first line connecting the first and fourth locations and second line connecting the second and third locations, wherein the angle is determined based on angles between the first line and each of planes XY, YZ, and XZ, respectively;
- and
- obtaining a first coordinate of the first location and a second coordinate of the fourth location relative to the first and second anchor devices based at least in part on the first, second, third and fourth distances and the angle.
