A tracking device including an image sensor, a light source and a processor is provided. The image sensor senses reflected light or scattered light formed by the light source illuminating a work surface. The processor calculates a trace of the tracking device according to one of the reflected light and the scattered light that generates more apparent image features so as to increase the adaptable work surfaces.

The disclosure is related to a sensor module, a sensor unit and a system for recognizing surrounding objects and defining an environment. The sensor module is installed in a sensor unit. The sensor module includes an optical element guiding the lights from the objects surrounding the sensor unit and to an image sensor, and the image sensor is used to sense the lights from the objects. The light can be directly from a light source inside the surrounding object or reflected by the object surface. The objects can be identified according to optical features obtained by the image sensor from surfaces of the objects. When the image sensor receives the two lights, guided by the optical element, and reads optical features being regarded as the unique IDs to identify the objects respectively. Therefore, an environment around the sensor unit can be defined.

An optical detecting module includes a housing, a light emitting component, an optical detecting component and an optical signal collecting component. The light emitting component is disposed inside the housing. The optical detecting component is disposed inside the housing to receive an optical detecting signal generated by the light emitting component. The optical signal collecting component is utilized to hold the light emitting component for signal collection. The optical signal collecting component includes an output portion, a bottom portion and at least one lateral portion. The light emitting component is disposed on the bottom portion, and an optical positive signal of the optical detecting signal is projected out of the housing through the output portion. The lateral portion is bent from the bottom portion to reflect an optical lateral signal of the optical detecting signal, and the optical lateral signal is projected out of the housing through the output portion.
