Beneficial effect: the device for the remote range finding of post-processed of the present utility model, adopted technique scheme, when needs are measured distance between two points, only the image measurement storage element need to be aimed to 2 tested points, and guarantee that they are in same picture, then take image and preservation, described at least two parallel laser device transmitter units with reference to indication device can be formed with two laser spots in image, the digital photograph that then will obtain, perhaps common photo is converted to the electronic pictures on plane, by using the distance between the measured point of software measurement, then measure respectively the distance of above-mentioned measured point-to-point transmission, and the distance between two laser spots, again according to the known distance between the optical axis of two laser instrument transmitter units, then bring into and contrast and calculate, just can calculate the distance of tested point-to-point transmission, it is to be noted distance between two above-mentioned measured points, for the projector distance of these two measured points in the vertical plane of the optical axis when taking pictures, if measure the real space distance of measured point-to-point transmission, need translation-angle to measure repeatedly, then by the equation of higher degree, solve.
The accompanying drawing explanation
Fig. 1, be the structural representation of a kind of preferred embodiment of the utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model, the technical scheme in the utility model is carried out to clear, complete description, obviously, described embodiment is a part of embodiment of the present utility model, rather than whole embodiment.Based on embodiment of the present utility model, those of ordinary skills obtain under the prerequisite of not making creative work every other embodiment, belong to the scope that the utility model is protected.
Please refer to shown in Figure 1, for a kind of preferred embodiment of device for the remote range finding of post-processed of the present utility model, in the present embodiment, should be for the device of the remote range finding of post-processed, for the picture catching storage element 1 of seizure and document image with reference to indication device, described parallel laser device transmitter unit 2 of mutually being connected by least two on-off circuits with reference to indication device forms, the optical axis of the laser beam that described at least two parallel laser device transmitter units are launched is arranged in parallel, and the optical axis of the optical axis of these two parallel laser device transmitter units and described picture catching storage element camera lens is parallel to each other, constant gap between the optical axis of at least two above-mentioned parallel laser device transmitter units, , usually, in the simplest embodiment, the number of the described transmitter unit of laser instrument with reference to indication device is 2, 2 the laser instrument transmitter units of below usining are set forth principle of the present utility model as scheme: for the technical scheme that 2 laser instrument transmitter units are arranged, device for the remote range finding of the post-processed of the present utility model step of operation usually is:
