Introduction

Arducam TOF SDK is a dynamic link library written in C++,There are three classes, Camera, Frame, and Sensor. Camera is responsible for managing camera image acquisition calculation, Frame is responsible for memory management of camera data storage, and Sensor is the specific implementation of calling camera. It is called as a member object in the Camera class, and users generally do not touch it. Specifically as shown in the figure below:

Mode introduction

We provide two modes, 2m range mode and 4m range mode, the difference between the modes is that the modulation frequency of light in 2m range mode is 75MHZ and the 4m range mode is 37.5MHZ. The unit of the depth value of the camera is millimeters.

Because of the different modulation frequencies, phase winding is more likely to occur in the 2-meter range mode because of the short range. The 4-meter range can effectively avoid phase winding.
