Detailed Description

Class which stores a image histogram from a camera image. This is used as an input when querying a image histogram.

Example code to query a image histogram for a left image corresponding to frameId 100

//
// Instantiate a channel connecting to a sensor at the factory default
// IP address
crl::multisense::Channel* channel;
channel = crl::multisense::Channel::Create("10.66.171.21");

channel->setMtu(7200);

//
// Create a histogram instance to store histogram data
crl::multisense::image::Histogram histogram;

uint64_t frameId = 100;

//
// Query the histogram from the image with the frameId == 100.
// Note histograms can only be queried for images whose frameIds are
// less than 20 frameIds away from the most recent received frameId
crl::multisense::Status status = channel->getImageHistogram(frameId, histogram);

//
// Check to see if the histogram query succeeded
if(crl::multisense::Status_Ok != status) {
     throw std::runtime_error("Unable to query image histogram for frameId %d", frameId);
}

//
// Destroy the channel instance
crl::multisense::Channel::Destroy(channel);

Member Data Documentation

uint32_t crl::multisense::image::Histogram::bins

The number of possible pixel values for each color channel

Definition at line 1271 of file MultiSenseTypes.hh.

uint32_t crl::multisense::image::Histogram::channels

The number of color channels in the given histogram. For color images this is 4 corresponding to the GRBG Bayer channels

Definition at line 1266 of file MultiSenseTypes.hh.

std::vector<uint32_t> crl::multisense::image::Histogram::data

The histogram data concatinated serially in GRBG order. The length of data is equal to channels * bins
