What are two methods of calibration?

How Do You Calibrate The DJI Vision Sensor

Calibration is the process of adjusting and validating the accuracy of a measuring instrument to ensure its measurements are reliable. Two common methods of calibration are:

  1. Calibration by Comparison (or Standardization): In this method, the instrument under test is compared to a known, more accurate standard. The standard can be a certified reference instrument or a physical artifact with a precisely known value. The instrument being calibrated and the standard are operated under the same conditions, and any discrepancies are adjusted to bring the instrument into alignment with the standard. This method is often used for calibrating instruments like thermometers, pressure gauges, and voltmeters.
  2. Calibration by Simulation (or Software Calibration): This method involves using a simulation or mathematical model to emulate the expected performance of the instrument. Instead of adjusting physical components, corrections are applied to the instrument’s output based on the simulated response. This is common in electronic devices, where calibration involves adjusting software settings or firmware to ensure accurate measurements. For example, digital multimeters and oscilloscopes may use software calibration to compensate for variations in components over time.

Both methods aim to minimize errors and uncertainties in measurement instruments, ensuring that they provide accurate and reliable results in various applications. The choice of calibration method depends on the type of instrument, the required level of accuracy, and the specific industry standards and regulations.
