Abstract: The present disclosure describes systems and methods for operating a movable object using a machine readable code. In one embodiment, an image may be obtained by the movable object. The image may include a machine-readable code configured to store a set of operation data for controlling the movable object. The movable object may process the image to retrieve the machine-readable code and the set of operation data. The movable object further may adjust one or more operation parameters of the movable object based on the set of operation data.

Abstract: Systems and methods for performing optical distance measurement are provided. In one aspect, a system for measuring a distance to an object comprises a light emitter configured to emit an outbound light pulse, and a light sensor configured to receive a returning light pulse reflected from the object and output an analog pulse signal representing the returning light pulse. The system also comprises a field-programmable gate array (FPGA) coupled to the light sensor. The FPGA is configured to convert the analog pulse signal to a plurality of digital signal values, and generate a plurality of time measurements corresponding to the plurality of digital signal values. The system also comprises a controller configured to calculate the distance to the object based on the plurality of digital signal values and the plurality of time measurements.
