template<bool HAS_4_BITS_INTERFACE>
class Metavision::AERDecoder : public Metavision::I_EventsStreamDecoder

Public Functions

inline virtual bool get_timestamp_shift(timestamp &ts_shift) const override

Finds the timestamp shift.

If the timestamp shift (timestamp of the first event in the stream) is already known, the function returns true and the parameter timestamp_shift will be set to its value. Otherwise, the function returns false and does nothing.

Returns

true if the timestamp shift is already known, false otherwise

inline virtual timestamp get_last_timestamp() const final override

Gets the timestamp of the last event.

Returns

Timestamp of the last event

inline virtual uint8_t get_raw_event_size_bytes() const override

Gets size of a raw event element in bytes.

If the timestamp shift (timestamp of the first event in the stream) is already known, the function returns true and the parameter timestamp_shift will be set to its value. Otherwise, the function returns false and does nothing.

Returns

true if the timestamp shift is already known, false otherwise

inline virtual timestamp get_last_timestamp() const override

Gets the timestamp of the last event.

Returns

Timestamp of the last event

inline virtual uint8_t get_raw_event_size_bytes() const override

class Metavision::MTRDecoder : public Metavision::I_EventFrameDecoder<PointCloud>

Public Functions

inline MTRDecoder(int sensor_width = 1280, int sensor_height = 720, MTRMode mode = MTRMode::MTR)

Constructor.

Parameters

• sensor_width – Width of the sensor

• sensor_height – Height of the sensor

• mode – MTR (Module for Triangulation) stream mode

inline virtual uint8_t get_raw_event_size_bytes() const override

Gets size of a raw event in bytes.

inline virtual void decode(const RawData *ev_bufferp, const RawData *evendp) override

Decodes raw event frame data.

Warning

It is mandatory to pass strictly consecutive buffers from the same source to this method

Parameters

• raw_data_begin – Pointer to start of frame data

• raw_data_end – Pointer after the last byte of frame data
