Abstract

The invention discloses a mobile data terminal, which comprises a front shell, a rear shell, a processor, a camera and an antenna module, wherein the camera is connected with the processor; the processor is connected with the antenna module; and a plumb line in the phase center of the antenna module is parallel to or coincides with that in the axis of the camera. The invention further discloses a positioning method utilizing the mobile data terminal. The positioning method comprises the steps of: shooting a surface mark point in real time and displaying the surface mark point in a display screen by the camera; receiving a satellite signal to obtain coordinate information of a phase center point of an antenna by the antenna module; and setting the plumb line in the phase center of the antenna module to be parallel to or coincide with that in the axis of the camera so as to obtain correct coordinate information of the point. According to the mobile data terminal manufactured by adopting the technical scheme, the standard camera is utilized, and a professional laser centering device or other auxiliary centering device is not required, so that the cost is reduced; the camera is built in the mobile data terminal and is good in drop resistance, so that the surface mark point can be very visually seen; and the mobile data terminal is convenient to operate.

Description

technical field [0001] The invention relates to a data terminal, in particular to a mobile data terminal and a positioning method thereof. Background technique [0002] At present, the existing mobile data terminals on the market are equipped with cameras, but the cameras are only used to transmit and take photos of the measured points at that time. The real alignment measurement requires a professional laser head or other auxiliary alignment devices, and the camera is not too Great practical significance, which greatly increases the cost. And the measurement requires other auxiliary centering devices, so the auxiliary centering components may be installed tilted, resulting in non-vertical deviations, resulting in inaccurate measurements. Contents of the invention [0003] In order to solve the above problems, the present invention provides a mobile data terminal with accurate measurement and low cost and a positioning method thereof. [0004] A mobile data terminal in t...
