Application of hand-held laser rangefinder in archaeological research
At present, the country archaeology widely USES the tape measure, the steel tape measure, the GPS, the total station instrument and so on to carry on the length, the area, the volume and so on quantity calculation, USES the total station instrument, the gps-rtk and so on to carry on the topographic mapping, the exploration layout, the project lotting.So what can hand-held laser rangefinders do?The handheld laser rangefinder can also be used for measuring distance, area, volume and lofting with the collaborative theodolite.
Distance measurement is the most widely used function in archaeology. The following two examples illustrate: 1. In the process of making the flat and section drawing of the tomb, the length, width and height of the tomb should be measured and registered, and then made according to the scale.It is assumed that the tomb is an earth pit tomb with a vertical hole and the mouth bottom is the same size. Suppose to measure the width of the tomb chamber, set the handheld laser rangefinder to initially calculate from the bottom of the instrument, and then stick the bottom of the handheld laser rangefinder to the tomb wall, stick to the horizontal button, and then the width of the tomb data will flash on the screen.The length measurement is similar to the width. The depth measurement can be directly measured from the tomb entrance, and the policy plate is also placed at the tomb entrance to measure from the bottom of the tomb. It is assumed that in order to avoid the influence of inclined tomb wall, the time delay measurement can be carried out by using extension bar when the bottom of the tomb mouth is different. 2. The measurement of the mound. Set the handheld laser rangefinder to triangulate, and then take the handheld laser rangefinder as the pole (preferably level with the bottom of the mound) and measure the distance to the bottom and top of the mound respectively. Then the height of the mound will be automatically calculated and flashed in the instrument. This function is particularly useful in the wild, in the Great Wall resources query some beacon tower climb up may be difficult to access, can use this function to measure the height of beacon tower;In the third national census of cultural relics, some ancient buildings, stone carvings are also very difficult to get close to, can also use this function measurement.
Area and volume measurements are also widely used in archaeology.For example, exploration area, tomb opening area, city site area, exploration square, tomb earthwork, etc. To use these functions, simply switch the function options of the handheld laser rangefinder to the corresponding options, and then measure two or three data of the entity to get the area and volume data.
Summary and Suggestions
The hand-held laser rangefinder is sensitive, accurate, simple and easy to operate.However, it also has disadvantages, such as: the measuring range is close, generally about 200 meters, can not meet the requirements of large planning measurement;Prices are high, usually ranging from hundreds to thousands of yuan.Therefore, in the archaeology we should use the hand-held laser rangefinder and other surveying and mapping instruments in cooperation, will give full play to the interests of various instruments, traveling archaeological surveying and mapping, mapping accuracy and power.
