A surveying device, in particular a video theodolite or video tachymeter, having - a base, - a support, which is pivotable in relation to the base about a first axis, - a targeting unit, which is pivotable in relation to the support about a second axis, having telescope optics defining an optical beam path having - an objective, - a physical targeting marking defining a targeting direction, in particular a crosshair, - an ocular, and - a camera for recording an image through the objective, - goniometers for measuring pivot positions of the support and the targeting unit, - an analysis and control unit, which contains stored calibration parameters with respect to an image position indicating the targeting direction in the recorded image as the targeting image position, and - a display screen for displaying a recorded image with marking for the targeting image position, in particular for displaying the image with superimposed electronic crosshair, the crosshair center point of which falls on the targeting image position, characterized by a partially automatic function for checking and/or recalibrating the targeting image position, wherein a sequence is defined for the function and corresponding items of sequence information are stored for this purpose in the analysis and control unit, during which sequence targeting actions of an identical target are successively performed at least once using the physical targeting marking and at least once using the marking for the targeting image position as a targeting aid, and wherein in the scope of the function, in a manner automatically controlled or carried out by the analysis and control unit - in response to a first trigger, which can be given in the event of completed targeting of the target using the physical targeting marking, first measurement data comprising a first pivot position of the support and the targeting unit, which is measured via the goniometers, and/or a first image recorded by the camera, are captured and added to a measurement data set, - in response to a second trigger, which can be given in the event of completed targeting of the target using the marking for the targeting image position as a targeting aid, second measurement data, which conform in type to the first measurement data, comprising a second pivot position of the support and the targeting unit, which is measured by the goniometers, and/or a second image recorded by the camera, are captured and added to the measurement data set, - the targeting image position is automatically checked, on the basis of a correlated analysis of the measurement data set, with respect to correspondence with the targeting direction defined by the physical targeting marking, and/or recalibrated by updating the stored calibration parameters, -
