Technical Field

[0001] The utility model relates to the technical field of TOF chips, and specifically relates to a height measuring device using a TOF chip. Background Art

[0002] The TOF chip is a key component for implementing TOF technology. TOF technology is a technology for calculating the distance of an object by measuring the time difference between the emission and reception of signals such as light or sound. Among TOF chips, the application of optical signals is more common because it has higher speed and a wider measurement range.

[0003] In view of the above and related existing technologies, the inventor believes that the following defects often exist: when measuring height, a special measuring instrument is used.
