#endif
 
int main()
{
#if defined(VISP_HAVE_OPENCV) && defined(HAVE_OPENCV_HIGHGUI) && defined(HAVE_OPENCV_IMGPROC) && defined(HAVE_OPENCV_IMGCODECS)
#ifdef ENABLE_VISP_NAMESPACE

#elif VISP_HAVE_OPENCV_VERSION >= 0x030000
    int flags = cv::IMREAD_GRAYSCALE;
#else
    int flags = CV_LOAD_IMAGE_GRAYSCALE;

[out]	grey	: Pointer to the 8-bits grey bitmap that should be allocated with a size of width * height.
[in]	width,height	: Image size.
[in]	flip	: When true, image is flipped vertically.
[in]	nThreads	: When > 0, the value is used to set the number of OpenMP threads used for the conversion.

	)

static

Convert a cv::Mat to a vpImage<vpRGBa>.

A cv::Mat is an OpenCV image class.

If the input image is of type CV_8UC1 or CV_8UC3, the alpha channel is set to vpRGBa::alpha_default, or 0 in certain case (see the warning below).

Warning: This function is only available if OpenCV (version 2.1.0 or greater) was detected during the configuration step.; If ViSP is built with SSSE3 flag and the CPU supports this intrinsics set, alpha channel will be set to 0, otherwise it will be set to vpRGBa::alpha_default (255).

Parameters

[in]	src	: Source image in OpenCV format.
[out]	dest	: Destination image in ViSP format.
[in]	flip	: Set to true to vertically flip the converted image.

	)

static

Create a point cloud from a depth image.

Parameters

[in]	depth_raw	: Depth raw image.
[in]	depth_scale	: Depth scale to apply to data in `depth_raw`.
[in]	cam_depth	: Depth camera intrinsics.
[out]	pointcloud	: Computed 3D point cloud. The 3D points reconstructed from the raw depth image are those that have their corresponding 2D projection in the depth mask and have a Z value within ]Z_min, Z_max[ range. When the depth mask is set to nullptr, we reconstruct all 3D points from the complete depth raw image and retain only those whose Z value lies between ]Z_min, Z_max[ range. You must also ensure that the size of the depth mask and the size of the depth raw image are the same.
[in,out]	pointcloud_mutex	: Optional mutex to protect from concurrent access to `pointcloud`. When set to nullptr, you should ensure that there is no thread that wants to access to `pointcloud`, like for example the one used in vpDisplayPCL.
[in]	depth_mask	: Optional depth_mask. When set to nullptr, all the pixels in `depth_raw` are considered. Otherwise, we consider only pixels that have a mask value that differ from 0.
[in]	Z_min	: Min Z value to retain the 3D point in the point cloud.
[in]	Z_max	: Max Z value to retain the 3D point in the point cloud.

Returns: The size of the point cloud.

◆ depthToPointCloud() [2/2]

int vpImageConvert::depthToPointCloud	(	const vpImage< vpRGBa > &	color,
		const vpImage< uint16_t > &	depth_raw,
		float	depth_scale,
		const vpCameraParameters &	cam_depth,
		pcl::PointCloud< pcl::PointXYZRGB >::Ptr	pointcloud,
		std::mutex *	pointcloud_mutex = `nullptr`,
		const vpImage< unsigned char > *	depth_mask = `nullptr`,
		float	Z_min = `0.2`,
		float	Z_max = `2.5`
	)

static

Create a textured point cloud from an aligned color and depth image.

Parameters

[in]	color	: Color image.
[in]	depth_raw	: Depth raw image.
[in]	depth_scale	: Depth scale to apply to data in `depth_raw`.
[in]	cam_depth	: Depth camera intrinsics.
[out]	pointcloud	: Computed 3D point cloud with RGB information. The 3D points reconstructed from the raw depth image are those that have their corresponding 2D projection in the depth mask and have a Z value within ]Z_min, Z_max[ range. When the depth mask is set to nullptr, we reconstruct all 3D points from the complete depth raw image and retain only those whose Z value lies between ]Z_min, Z_max[ range.
[in,out]	pointcloud_mutex	: Optional mutex to protect from concurrent access to `pointcloud`. When set to nullptr, you should ensure that there is no thread that wants to access to `pointcloud`, like for example the one used in vpDisplayPCL.
[in]	depth_mask	: Optional depth_mask. When set to nullptr, all the pixels in `depth_raw` are considered. Otherwise, we consider only pixels that have a mask value that differ from 0 and that a Z value in ]Z_min, Z_max[] range. You should also ensure that mask size and `depth_raw` size are the same.
[in]	Z_min	: Min Z value to retain the 3D point in the point cloud.
[in]	Z_max	: Max Z value to retain the 3D point in the point cloud.

Returns: The size of the point cloud.

Convert an image from YCbCr 4:2:2 (Y0 Cb01 Y1 Cr01 Y2 Cb23 Y3...) to RGBa format. Destination rgba memory area has to be allocated before.

The alpha component of the converted image is set to vpRGBa::alpha_default.

In YCbCr (4:2:2) format each pixel is coded using 16 bytes. Byte 0: YO (Luma for Pixel 0) Byte 1: Chroma Blue Cb (Blue Chroma for Pixel 0 and 1) Byte 2: Y1 (Luma for Pixel 1) Byte 3: Chroma Red Cr (Red Chroma for Pixel 0 and 1) Byte 4: Y2 (Luma for Pixel 2)
In RGBa format, each pixel is coded using 24 bytes. Byte 0: Red Byte 1: Green Byte 2: Blue Byte 3: -

Parameters

[in]	ycbcr	: Pointer to the bitmap containing the YCbCr 4:2:2 data.
[out]	rgba	: Pointer to the 32-bits RGBA bitmap that should be allocated with a size of width * height * 4.
