Abstract
A target for use in surveying applications is provided. The target comprises a plurality of light sources arranged around a longitudinal axis (A) of a base element of the target. The plurality of light sources is configured to emit light radially. The target further comprises a control unit. The control unit is configured to receive, from a surveying instrument aimed towards the target, an input indicative of a distance (d) between the target and the surveying instrument. The control unit is further configured to control an intensity of the light emitted by the plurality of light sources based on the input indicative of the distance between the target and the surveying instrument.
Claims13
A target for use in surveying applications, the target comprising:
- a plurality of light sources arranged around a longitudinal axis (A) of a base element of said target and configured to emit light radially;
- and
- a control unit configured to:
- receive, from a surveying instrument aimed towards the target, an input indicative of a distance (d) between the target and the surveying instrument, the input comprising a position of the surveying instrument;
- determine, from a target position input received from an external source, a position of the target;
- determine the distance between the surveying instrument and the target based on the received position of the surveying instrument and the determined position of the target;
- and
- control an intensity of the light emitted by the plurality of light sources based on the determined distance.
A target for use in surveying applications, the target comprising:
- a plurality of light sources arranged around a longitudinal axis (A) of a base element of said target and configured to emit light radially;
- and
- a control unit configured to:
- receive, from a surveying instrument aimed towards the target, an input indicative of a distance (d) between the target and the surveying instrument, wherein said input indicative of a distance between the target and the surveying instrument comprises a measured optical signal strength of light emitted by said plurality of light sources and detected by a light detector of said surveying instrument;
- and
- control an intensity of the light emitted by the plurality of light sources based on a difference between the measured optical signal strength and an optical signal strength model.
A target for use in surveying applications, the target comprising:
- a plurality of light sources arranged around a longitudinal axis (A) of a base element of said target and configured to emit light radially;
- and
- a control unit configured to:
- receive, from a surveying instrument aimed towards the target, an input indicative of a distance (d) between the target and the surveying instrument, wherein said input indicative of a distance between the target and the surveying instrument comprises a wireless communication between the surveying instrument and the target;
- and
- control an intensity of the light emitted by the plurality of light sources based on a signal strength of the wireless communication.
A target for use in surveying applications, the target comprising:
- a plurality of light sources arranged around a longitudinal axis (A) of a base element of said target and configured to emit light radially;
- and
- a control unit configured to:
- receive, from a surveying instrument aimed towards the target, an input indicative of a distance (d) between the target and the surveying instrument;
- control an intensity of the light emitted by the plurality of light sources based on the input indicative of the distance between the target and the surveying instrument;
- receive, from the surveying instrument, an indication that the surveying instrument is not aimed towards the target;
- and
- upon reception of said indication, control the intensity of the light emitted by the plurality of light sources to be at a maximum level.
A method for operating a target for use in surveying applications, the target comprising a plurality of light sources arranged around a longitudinal axis of a base element of said target and configured to emit light radially, the method comprising:
- receiving, from a surveying instrument aimed towards the target, an input indicative of a distance between the target and the surveying instrument;
- controlling an intensity of the light emitted by the plurality of light sources based on the input indicative of the distance between the target and the surveying instrument;
- receiving, from the surveying instrument, an indication that the surveying instrument is not aimed towards the target;
- and
- upon reception of said indication, controlling the intensity of the light emitted by the plurality of light sources to be at a maximum level.
