1. Color of the target object: The ranging sensor has certain requirements for the color of the target object. For example, brighter colors such as white, red, and yellow have higher reflectivity than black, so the measured distance and accuracy will also be different.

2. Surface properties of the target object: The surface properties of the target object will also affect the accuracy of the measurement. If the target object surface is a mirror, then there is only one direction of light reflection, which will affect the sensor's measurement. In addition, if the target object is a porous or translucent material, it may cause measurement errors of the sensor.

3. Coating on metal surface: The metal surface has some diffuse reflection on the bare metal surface, but the reflectivity of the metal surface is inconsistent. Therefore, the repeatability accuracy of different detection points or the same detection point on the metal surface will be reduced. This effect varies from metal to metal and depends on the coating on the metal surface.

4. Working distance and size of measured object: Working distance and size of measured object will affect the accuracy of measurement. Generally speaking, the larger the size of the object being measured and the farther the working distance, the lower the measurement accuracy.

5. Atmospheric conditions: Atmospheric conditions such as humidity, temperature, pressure, etc. will also affect the measurement accuracy of the laser ranging sensor.

6. Equipment performance and settings: Factors such as the equipment performance of the laser ranging sensor, the power of the laser transmitter, the design of the optical system, the sensitivity of the receiver, as well as the ambient temperature and wind speed during measurement will all affect its measurement accuracy.

7. Algorithm and software processing: The accuracy of the ranging sensor is also related to the algorithm and software processing it uses. For example, different data processing algorithms may have an impact on the final measurement results.

In general, the difference in accuracy of laser ranging sensors is the result of a combination of factors. When using a laser ranging sensor, it is necessary to comprehensively consider the actual situation and select appropriate equipment and technical parameters.
