Peak Detection

The Peak Detection module produces a depth map represented by 16-bit fixed-point words. It can be configured with two precisions:

●

UQ11.5 in which 5-bit (LSB) represent the fraction part and 11-bit (MSB) the integer part. In this mode, the maximum effective LLE-ROI YSize supported by the Peak Detection module is almost 2048 Pixels.

●

UQ8.8 in which 8-bit (LSB) represent the fraction part and 8-bit (MSB) the integer part. In this mode, the maximum effective LLE-ROI YSize supported by the Peak Detection module is almost 256 Pixels.

When more than one peak is detected on a given LLE-ROI column, the Peak Detection module will indicate the position of the one where the corresponding f(x) pixel has the highest intensity. If more than one corresponding f(x) pixel have the same condition (highest intensity), then the one with highest position among them will be indicated.

InvalidDataFlag

An InvalidDataFlag is generated when:

●

The detected line position is above the max LLE-ROI height supported.

●

No line is detected in an LLE-ROI column.
