measurement
Measuring and measurement are important concepts in software engineering. According to the standard dictionary of software engineering terms, measurement is a quantitative measurement of a given attribute of a system, component, or process. It is established by collecting the results of one or more data points. For example, the number of errors found in a module review is a measure. And measurement was a means of measuring or indicating something that could not be directly measured, observed, or expressed. It is an estimate or measurement of length, size, or capacity, usually expressed in numerical units. In software engineering, software engineers collect measurement results to produce measurements and obtain indicators. Therefore, measurement and measurement are related and complementary concepts in software engineering.

Photographic measurement
Photogrammetry was a technique that used a combination of a camera and film to measure the shape, size, and spatial position of a target. It used the image of the object to reconstruct the spatial position and three-dimensional shape of the object, thereby obtaining the spatial information of the ground or other objects. The core problem was to use the two-dimensional image to obtain the three-dimensional coordinates of the target. Since the invention of photography by Nippes and Dayle in 1839, photogrammetry had a history of more than 170 years. It had gone through three stages: simulation photogrammetry, analytical photogrammetry, and digital photogrammetry.
In modern times, the principle of photogrammetry was similar to a puzzle. By capturing and stitching image information to create a digital model of the physical world, images were like " puzzle pieces." The more images captured and collected, the more realistic and detailed the 3D model. The effect depended on the quality of the data set, so the correct shooting method was very important.
Photogrammetry is divided into aerial photogrammetry and ground photogrammetry. Aerial photosurveying placed the camera in the air for large or difficult to access areas. It was one of the widely used methods of establishing a geographical database in the field of forest and natural resource management. Ground photosurveying focused on the focus of the measurement object, usually relying on images taken by a hand-held camera or a camera fixed on a tripod. It could quickly collect field data and capture more detailed images.
There was also a professional term like control point in photogrammetry. It was a control point that was directly measured on the spot for photogrammetry encryption or map measurement. It was the basis for photogrammetry control encryption and map measurement. It could correct errors caused by many factors. According to the use, it was divided into plane point, elevation point, or flat point, and there were corresponding selection and measurement requirements.

Distance measurement algorithm
The following is an algorithm for measuring distance with fingers (using the thumb as an example): Raise your right arm horizontally, make a fist with your right hand, and raise your thumb. Using his right eye (left eye closed), he overlapped the left side of his thumb with the target in a straight line. If the right arm and thumb were still, he would close his right eye and observe the left side of the thumb with his left eye. He would find that the boundary was a distance away from the right side of the target. He estimated the distance and multiplied it by 10. The result was the approximate distance to the target. This method required a certain amount of experience, and there were some objective things that could provide some reference. For example, the size of the house and the distance between the houses were generally about 10 meters, or the distance between the utility poles was 50 meters, the town utility poles were 100 meters, and the high-voltage power was 200 meters. He still needed to practice more to be able to use it skillfully, and the measurement error would be smaller. The other way was to place your thumb in front of you (with your arm fully extended) and close one eye. Hover your thumb over an object of known size (such as a car). In the case of not moving the thumb, close the open eye and open the other eye to estimate the distance that the thumb has "moved" relative to the object you are looking at. For example, the length of a car is known to be about 4.5 meters. If the thumb moves half of the length of the car (about 2.25 meters), multiply the result by 10 to obtain the approximate distance between the car and you (in this case, about 22.5 meters).

A unit of measurement for spaceships
The number of spaceships was usually measured in units of "ships" or "bars". This was because a spaceship could be seen as a ship in a sense, and the words " Shou " and " Tiao " were more suitable for ships.
The novel " Hundred Years of Spaceship " is equally exciting. Everyone is welcome to click and read it!

How did the 'kings foot measurement story' influence historical measurement systems?
It led to inconsistency. Since different kings had different foot sizes, the unit of measurement kept changing. This made it hard for trade and construction across regions.

Satellite map measurement area
You can use the Tuxin Earth desktop software (LMV) to measure the area. First, open the software to load the satellite map in the online map and locate the area to be measured. Draw the area according to the operation instructions of the measurement analysis function. After the measurement analysis-area measurement double-click to complete the operation, the area can be obtained. In addition, the Earth APP could measure distance and area at any point. The Symbiotic Earth APP had outdoor measurement functions to help with geographical exploration and surveying planning. The measurement functions in these apps could use satellite maps for area measurement.

F8 on boot
Pressing F8 was the shortcut key to enter safe mode. In the Windows system, pressing the F8 key could enter the safe mode. This was a boot mode that could be used to resolve system faults and eliminate problems. After entering the safe mode, the user could perform some diagnosis and repair operations, such as deleting stubborn files and clearing the contents of the resource recycling bin. However, it should be noted that with the update of the Windows system, especially in the versions of Windows 8 and later, the function of pressing F8 to enter the safe mode has changed. You may need to use other methods or adjust the system settings to enter the safe mode.

How accurate is the measurement of the guy in the cartoon?
It's not very precise. The measurement seems to be rather approximate and might not be reliable.
